Parse xml for newline chars using xpath

Hi guys,
need your help.
I was curious to how can we use subString-before and subString after function to extracts records based on newline.
Ex.
for an strin xml field with data
1st line
2nd line
and want to extract each line as separate record.
Hope i am clear on req.
anybody done something similar before?
Thanks in advance.

While SOA is based on handling XML messages, it has no relation with a presentation layer. Characters such as new-line, line-feed are processed as whitespace.
If you want to add specific characters, you must encode this. So a new line would be 
 This also applies for characters like quote and less-then and greater then.
You must encode your information into UTF8 format.

Parsing xml for complex type using sax

I have an xsd of below type:
<xs:complexType name="itemInfo">
 <xs:sequence>
 <xs:element name="displayLineNumber" type="xs:string" minOccurs="0"/>
 <xs:element name="lineNumber" type="xs:integer" minOccurs="0"/>
 <xs:element name="parentLineNumber" type="xs:integer" minOccurs="0"/>
 <xs:element name="service" type="serviceInfo" minOccurs="0" maxOccurs="unbounded"/>
 </xs:sequence>
</xs:complexType>
<xs:complexType name="serviceInfo">
 <xs:sequence>
 <xs:element name="displayLineNumber" type="xs:string" minOccurs="0"/>
 <xs:element name="lineNumber" type="xs:integer" minOccurs="0"/>
 <xs:element name="serviceName" type="xs:string" minOccurs="0"/>
 <xs:element name="serviceDescription" type="xs:string" minOccurs="0"/>
 <xs:element name="subscriptionBand" type="subscriptionBandInfo" minOccurs="0" maxOccurs="unbounded"/>
 </xs:sequence>
</xs:complexType>
<xs:complexType name="subscriptionBandInfo">
 <xs:sequence>
 <xs:element name="min" type="xs:long"/>
 <xs:element name="max" type="xs:long"/>
 <xs:element name="duration" type="xs:string" minOccurs="0"/>
 <xs:element name="price" type="xs:decimal"/>
 </xs:sequence>
</xs:complexType>
I have written a handler and able to handle simple type but how I can handle serviceInfo and subscriptionBandInfo as itemInfo is my root element.
My handler class is:
public class ProductHandler
extends DefaultHandler
//List to hold ProductInfo object
private List<ProductInfo> productList = null;
private ProductInfo product = null;
public List<ProductInfo> getProductList()
 return productList;
boolean bDisplayLineNumber = false;
boolean bLineNumber = false;
boolean bParentLineNumber = false;
@Override
public void startElement(String uri, String localName, String qName, Attributes attributes)
 throws SAXException
 if (qName.equalsIgnoreCase("item"))
 { //create a new ProductInfo and put it in Map
 //initialize ProductInfo object and set id attribute
 product = new ProductInfo();
 //initialize list
 if (productList == null)
 productList = new ArrayList<ProductInfo>();
 else if (qName.equalsIgnoreCase("name"))
 //set boolean values for fields, will be used in setting ProductInfo variables
 bName = true;
 else if (qName.equalsIgnoreCase("displayLineNumber"))
 bDisplayLineNumber = true;
 else if (qName.equalsIgnoreCase("lineNumber"))
 bLineNumber = true;
 else if (qName.equalsIgnoreCase("parentLineNumber"))
 bParentNumber = true;
@Override
public void endElement(String uri, String localName, String qName)
 throws SAXException
 if (qName.equalsIgnoreCase("item"))
 //add ProductInfo object to list
 productList.add(product);
@Override
public void characters(char ch[], int start, int length)
 throws SAXException
 if (bDisplayLineNumber)
 product.setDisplayLineNumber(Integer.parseInt(new String(ch, start, length)));
 bDisplayLineNumber = false;
 else if (bLineNumber)
 product.setLineNumber(Integer.parseInt(new String(ch, start, length)));
 bLineNumber = false;
 else if (bParentNumber)
 product.setParentNumber(Integer.parseInt(new String(ch, start, length)));
 bParentNumber = false;
@Override
public void endElement(String uri, String localName, String qName)
 throws SAXException
 if (qName.equalsIgnoreCase("item"))
 //add ProductInfo object to list
 productList.add(product);
My ProductInfo class is:
import com.vpc.schema.ServiceInfo;
import java.util.ArrayList;
import java.util.List;
public class ProductInfo
private String category, family, subGroup, size, productType, availability;
private String displayLineNumber;
private int lineNumber;
private int parentNumber;
private List<ServiceInfo> serviceInfo;
public int getLineNumber()
 return lineNumber;
public int getParentNumber()
 return parentNumber;
public List<ServiceInfo> getServiceInfo()
 if (serviceInfo == null)
 serviceInfo = new ArrayList<ServiceInfo>();
 return serviceInfo;
public void setServiceInfo(List<ServiceInfo> serviceInfo)
 this.serviceInfo = serviceInfo;
I am able to do parsing for my simple type but when a complex type comes I am not able to do it. So please suggest how I can add complex type

I suppose the posting of xsd is to show the structure of the xml...
In any case, I can suggest a couple of things to do for the purpose.
[1] If you still follow the same line of reasoning using some boolean like bDisplayLineNumber etc to identify the position of the parser traversing the document, you can complete the logic adding bItem (which you did not need under simplified consideration) and bService and bSubscriptionBand to identify at the parent or the grandparent in the case of the "complexType" serviceInfo and even the great-grand-parent in the case of arriving to the complexType subscriptionBandInfo...
[1.1] With those boolean value, you determine bDisplayLineNumber etc under item directly, and then as well say bDisplayLineNumber_Service under the service etc and then bMin_SubscriptionBand etc under subscriptionBand etc. You just expand the number of those variables to trigger the setting of those fields in the object product, service in the serviceList and subscriptionBand in the subscriptionBandList etc etc.
[1.2] All the reset of those booleans should be done in the endElement() method rather than in characters() method. That is logically more satisfactory and has a bearing in case there is a mixed content type.
[1.3] Then when arriving at startElement of service, you make sure you initiate the serviceList, same for subscriptionBand the subscriptionList...
[1.4] Then when arriving at endElement of service, you use setServiceInfo() setter to pass the serviceList to product and the same when arriving at endElement of serviceBand, you use setSubscriptionBand() setter to pass the subscriptionBand to service.
... and then basically that's is it, somewhat laborious and repetitive but the logical layout is clear. (As a side-note, you shouldn't use equalsIgnoreCase(), why should you? xml is case sensitive.)
[2] Actually, I would suggest a much neater approach, especially when you probe many more levels of complexType. It would be even appear cleaner when you have two levels of depth already...
[2.1] You maintain a Stack (or an implementation class of Deque, but Stack is largely sufficient here) of element name to guide the parser identifying its whereabout. By such doing, you get ride of all those bXXX's.
This is a rewrite of the content handler using this approach and I only write the code of capturing service. Adding serviceBand is a matter of repetition of how it is done on service. And it is already clear it appears a lot neater as far as I'm concerned.
public class ProductHandler extends DefaultHandler {
Stack<String> tagstack=new Stack<String>();
private List<ProductInfo> productList = null;
private ProductInfo product = null;
private List<ServiceInfo> serviceList=null;
private ServiceInfo service=null;
public List<ProductInfo> getProductList() {
return productList;
public List<ServiceInfo> getServiceList() {
return serviceList;
@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) {
if (qName.equals("item")) {
 product = new ProductInfo();
 //initialize list
 if (productList == null) {
 productList = new ArrayList<ProductInfo>();
} else if (qName.equals("service") && tagstack.peek().equals("item")) {
 service=new ServiceInfo();
 if (serviceList==null) {
 serviceList=new ArrayList<ServiceInfo>();
tagstack.push(qName);
@Override
public void endElement(String uri, String localName, String qName) {
if (tagstack.peek().equals("item")) {
 //add ProductInfo object to list
 productList.add(product);
} else if (tagstack.peek().equals("service") && tagstack.search("item")==2) {
 serviceList.add(service);
 product.setServiceInfo(serviceList);
tagstack.pop();
@Override
public void characters(char ch[], int start, int length) throws SAXException {
String currentName=tagstack.peek();
int itemPos=tagstack.search("item");
int servicePos=tagstack.search("service");
if (currentName.equals("name") && itemPos==2) {
 product.setName(new String(ch, start, length));
} else if (currentName.equals("displayLineNumber") && itemPos==2) {
 product.setDisplayLineNumber(Integer.parseInt(new String(ch, start, length)));
} else if (currentName.equals("lineNumber") && itemPos==2) {
 product.setLineNumber(Integer.parseInt(new String(ch, start, length)));
} else if (currentName.equals("parentLineNumber") && itemPos==2) {
 product.setParentLineNumber(Integer.parseInt(new String(ch, start, length)));
} else if (currentName.equals("displayLineNumber") && servicePos==2 && itemPos==3) {
 service.setDisplayLineNumber(Integer.parseInt(new String(ch, start, length)));
} else if (currentName.equals("lineNumber") && servicePos==2 && itemPos==3) {
 service.setLineNumber(Integer.parseInt(new String(ch, start, length)));

How to parse XML for internal table

hi guys, I would like to know how to parse xml for an internal table. I explain myself.
Let's say you have a purchase order form where you have header data & items data. In my interactive form, the user can change the purchase order quantity at the item level. When I received back the pdf completed by mail, I need to parse the xml and get the po qty that has been entered.
This is how I do to get header data from my form
lr_ixml_node = lr_ixml_document->find_from_name( name = ''EBELN ).
lv_ebeln = lr_ixml_node->get_value( ).
How do we do to get the table body??
Should I used the same method (find_from_name) and passing the depth parameter inside a do/enddo?
thanks
Alexandre Giguere

Alexandre,
Here is an example. Suppose your internal table is called 'ITEMS'.
lr_node = lr_document->find_from_name('ITEMS').
lv_num_of_children = lr_node->num_children( ).
lr_nodechild = lr_node->get_first_child( ).
do lv_num_of_children times.
    lv_num_of_attributes = lr_nodechild->num_children( ).
    lr_childchild = lr_nodechild->get_first_child( ).
   do lv_num_of_attributes times.
      lv_value = lr_childchild->get_value( ).
      case sy-index.
         when 1.
           wa_item-field1 = lv_value
         when 2.
           wa_item-field2 = lv_value.
      endcase.
      lr_childchild = lr_childchild->get_next( ).
   enddo.
   append wa_item to lt_item.
   lr_nodechild = lr_nodechild->get_next( ).
enddo.

Set XML attribute from SetValue using Xpath

Is there a trick to assigning a value to an attribute of an element in an XML variable using XPATH inside a setValue activity? When I try something like
Location
/process_var/xml_var/test/@ID
Expression:
/process_var/test_value
it complains about the @ sign in the location assignment. I seem to be able to retrieve attributes just fine.

Still having this issue.
If I have an XML process variable which currently contains
<Document>
 <Title />
 <Author />
 <Date />
</Document>
Try this, it fails.
Location: /process_data/xml/Document/@ID
Expression: 54
Try this, it works.
Location: /process_data/xml/Document/ID
Expression: 54
Now, alter the XML by adding an ID attribute
<Document ID="">
 <Title />
 <Author />
 <Date />
</Document>
Try this, it works, where it failed earlier.
Location: /process_data/xml/Document/@ID
Expression: 54
It appears to me, you can ADD a new node, but you can't ADD an attribute

Accessing documents in xml db in browser using xpath not returning results

I have loaded the purchaseorder documents and schema (from Oracle Magazine article (Mar/Apr 2003) "From XML to Storage and Back" article.
I am able to access the LineItems element of the purchaseorder document using:
http://localhost:8080/oradb/SCOTT/PURCHASEORDER/ROW/PurchaseOrder[Reference="ADAMS-20011127121040988PST"]/LineItems
However, I cannot access the indivicual LineItem elements using the ItemNumber attribute:
http://localhost:8080/oradb/SCOTT/PURCHASEORDER/ROW/PurchaseOrder[Reference="ADAMS-20011127121040988PST"]/LineItems/LineItem[@ItemNumber="2"]
I get the following result:
<?xml version="1.0"?>
<ERROR>ORA-00904::invalid identifier</ERROR>
I need to be able to use this and other xpath statements to extract elements from my document. Any suggestions?

I'm including a sample purchase order:

Parse xml for conky

I'd like to capture two key outputs and have them displayed in conky. On my system, GPU load and GPU memory usage are available from the nvidia-smi program. I can output in xml format which I'd like to parse and harvest to display in conky. I can brute-force myself through it via grep and sed statements, but I'm looking for some suggestions from more knowledgeable people to do this in a minimal way. For example, only run the program once, and harvest all data. My current solution runs twice.
Example output:
$ nvidia-smi -a -x
<?xml version="1.0" ?>

Or it might be better not to go to xml which I can do by omitting the -x switch:
$ nvidia-smi -a

Damn, my memory is truly shit. Thanks, ST. The awk syntax is still foreign to me. How would I segregate the RAM usage from the GPU usage? I think conky needs the output to be unique for each one in their own script.

Parse xml for font / paragraph styling

Has anyone tried to understand the XML representation of font style (or as I believe it is defined in the XML, "paragraphstyle")? I am having trouble getting all the lookups. I get multiple results. I am not an expert on XML. Is "property-map" a term that is unique to this XML definition, or is their a standard way to look up values via an XML property-map.
I am wondering if I need a combination of styletheetID, paragraphstyleID and parent-ident, just to get a single lookup val?
I have pasted what my return results look like:
<sf:paragraphstyle sfa:ID="SFWPParagraphStyle-94" sf:parent-ident="titleHeadlineParagraphStyleID">
<sf:property-map/>
</sf:paragraphstyle>
<sf:paragraphstyle sfa:ID="SFWPParagraphStyle-94" sf:parent-ident="slideNotesParagraphStyleID">
<sf:property-map/>
</sf:paragraphstyle>
<sf:paragraphstyle sfa:ID="SFWPParagraphStyle-94" sf:parent-ident="shapeParagraphStyleID">
<sf:property-map>
<sf:fontName>
<sf:string sfa:string="CopperplateGothic-Bold"/>
</sf:fontName>
<sf:fontColor>
<sf:color xsi:type="sfa:calibrated-white-color-type" sfa:w="0.90196079015731812" sfa:a="1"/>
</sf:fontColor>
<sf:fontSize>
<sf:number sfa:number="18" sfa:type="q"/>
</sf:fontSize>
</sf:property-map>
</sf:paragraphstyle>
<sf:paragraphstyle sfa:ID="SFWPParagraphStyle-94" sf:parent-ident="level1HeadlineParagraphStyleID">
<sf:property-map/>
</sf:paragraphstyle>
<sf:paragraphstyle sfa:ID="SFWPParagraphStyle-94" sf:parent-ident="shapeParagraphStyleID">
<sf:property-map>
<sf:fontName>
<sf:string sfa:string="Corbel-Bold"/>
</sf:fontName>
<sf:fontColor>
<sf:color xsi:type="sfa:calibrated-white-color-type" sfa:w="0.90196079015731812" sfa:a="1"/>
</sf:fontColor>
<sf:fontSize>
<sf:number sfa:number="18" sfa:type="q"/>
</sf:fontSize>
</sf:property-map>
</sf:paragraphstyle>
<sf:paragraphstyle sfa:ID="SFWPParagraphStyle-94" sf:parent-ident="shapeParagraphStyleID">
<sf:property-map>
<sf:fontName>
<sf:string sfa:string="Futura-Medium"/>
</sf:fontName>
<sf:alignment/>
<sf:fontColor>
<sf:color xsi:type="sfa:calibrated-white-color-type" sfa:w="0.90196079015731812" sfa:a="1"/>
</sf:fontColor>
<sf:fontSize/>
</sf:property-map>
</sf:paragraphstyle>
I should also note another weird behavior... when I do a "find" within the text application I only get two results for "SFWPParagraphStyle-94", one for the paragraph where it is used, and one in the stylesheet section where it is defined (ie. the return result that I expect).

I am trying to decipher what the current text formatting of a shape is. I am parsing through the slides, parsing through the shapes of a slide, and am now trying to lookup/extract the formatting of the text that is inside the shape.
which looks like this in my test file:
<sf:p sf:style="SFWPParagraphStyle-94">Centered, has a font override<sf:br/></sf:p>
<sf:p sf:style="SFWPParagraphStyle-94">and line break</sf:p>
With regards to the post above, I was making a rookie error... I was using:
xml.blablabla.paragraphstyle.(@ID="SFWPParagraphStyle-94");
instead of
xml.blablabla.paragraphstyle.(@ID=="SFWPParagraphStyle-94");
.... so that obviously now clears that up.... totally.. duh
Now I am just trying to continue to look up all the inheritance formatting... which to me, at this point is not that straight forward. So I would prefer to leave this thread open as to "how to parse for text formatting"
So far I am:
getting the stylesheet-ref
looking up the paragraphStyle
which then points to the master-slide
....

Fetching xml node nth value using Xpath

HI Experts ,
with reference to below question, i have one more doubt.
https://social.msdn.microsoft.com/Forums/en-US/f894e5e2-8926-4604-9171-616da3f00cd7/xpath-to-fetch-value-in-flatfile-schema?forum=biztalkgeneral
I used below xpath to fetch nth value of full repeating message nodes
indexStr = System.Convert.ToString(index);DATE=xpath(In_FF, "string(//*[local-name() = 'Details']["+indexStr+"])/*[local-name()='DATE'])");index=index + 1;
and i got below error, can any help me in this?
Exception thrown from: segment 2, progress 43
Inner exception: 'string(//*[local-name() = 'Details'][1])/*[local-name()='DATE'])' has an invalid token.
Exception type: XPathException
Source: System.Xml
Target Site: MS.Internal.Xml.XPath.AstNode ParseXPathExpresion(System.String)
The following is a stack trace that identifies the location where the exception occured

your XPATH expression is WRONG.
it should be
DATE=xpath(In_FF,
"string(//*[local-name() = 'Details']["+indexStr+"]/*[local-name()='DATE'])");
There is NO ")" after ["+indexStr+"].
The more reliable way is to use a string variable and use the System.String.Format() call as below
xPathExpr = System.String.Format("string(//*[local-name() = 'Details'][{0}]/*[local-name()='DATE'])", index);
DATE=xpath(In_FF, xPathExpr);
The "invalid token" is because of the mismatched ")" in your XPATH Expression.

Very high parse times for query rewrite using cube materialized views

We recently upgraded to version 11.2.0.2 (both AWM and Oracle database server). We are using cube materialized views with query rewrite enabled. Some observations of changes that took place when we rebuilt all the dimensions and cubes in this version:
1. Queries against the base tables take about 35 seconds to parse. Then they execute in a tenth of a second. Even simple queries that just get a sum of the amount from the fact table (which is joined to all the dimensions) takes that long to parse. Once parsed, the queries fly.
2. I noticed that the materialized views used to use grouping sets in the group by clause in version 11.2.0.1, but now they use group by rollup, rollup, rollup...
If we disable query rewrite on the MV or for my session, parse times drop to less than a second. Ideas?

There does appear to be a slow down in parse times between 11.1.0.7 and 11.2. We are still investigating this, but in the meantime here is a way to force the code in 11.2 to generate a GROUPING SETS clause instead of the new ROLLUP syntax.
The trick is to create a dummy hierarchy containing only the leaf level. This is necessary for all dimensions that currently have a single hierarchy. As a simple example I created a dimension, PROD, with three levels, A, B, and C, in a single hierarchy. I then created a one dimensional cube, PC. Here is the SELECT statement for the MV in 11.2. Note the ROLLUP clause in the GROUP BY.
SELECT
GROUPING_ID(T3."CLASS_ID", T3."FAMILY_ID", T3."ITEM_ID") SYS_GID,
(CASE GROUPING_ID(T3."CLASS_ID", T3."FAMILY_ID", T3."ITEM_ID")
   WHEN 3
   THEN TO_CHAR(('A_' || T3."CLASS_ID") )
   WHEN 1
   THEN TO_CHAR(('B_' || T3."FAMILY_ID") )
   ELSE TO_CHAR(('C_' || T3."ITEM_ID") ) END)     "PROD",
T3."CLASS_ID" "D1_PROD_A_ID",
T3."FAMILY_ID" "D1_PROD_B_ID",
T3."ITEM_ID" "D1_PROD_C_ID",
SUM(T2."UNIT_PRICE")     "PRICE",
COUNT(T2."UNIT_PRICE") "COUNT_PRICE",
COUNT(*) "SYS_COUNT"
FROM
GLOBAL."PRICE_AND_COST_FACT" T2,
GLOBAL."PRODUCT_DIM" T3
WHERE
(T3."ITEM_ID" = T2."ITEM_ID")
GROUP BY
(T3."CLASS_ID") ,
ROLLUP ((T3."FAMILY_ID") , (T3."ITEM_ID") )Next I modified the dimension to add a new hierarchy, DUMMY, containing just the leaf level, C. Once I have mapped the new level and re-enabled MVs, I get the following formulation.
SELECT
GROUPING_ID(T3."CLASS_ID", T3."FAMILY_ID", T3."ITEM_ID") SYS_GID,
(CASE GROUPING_ID(T3."CLASS_ID", T3."FAMILY_ID", T3."ITEM_ID")
   WHEN 3
   THEN ('A_' || T3."CLASS_ID")
   WHEN 1
   THEN ('B_' || T3."FAMILY_ID")
   WHEN 0
   THEN ('C_' || T3."ITEM_ID")
   ELSE NULL END) "PROD",
T3."CLASS_ID" "D1_PROD_A_ID",
T3."FAMILY_ID" "D1_PROD_B_ID",
T3."ITEM_ID" "D1_PROD_C_ID",
SUM(T2."UNIT_PRICE")     "PRICE",
COUNT(T2."UNIT_PRICE") "COUNT_PRICE",
COUNT(*) "SYS_COUNT"
FROM
GLOBAL."PRICE_AND_COST_FACT" T2,
GLOBAL."PRODUCT_DIM" T3
WHERE
(T3."ITEM_ID" = T2."ITEM_ID")
GROUP BY
GROUPING SETS ((T3."CLASS_ID") , (T3."FAMILY_ID", T3."CLASS_ID") , (T3."ITEM_ID", T3."FAMILY_ID", T3."CLASS_ID") )This puts things back the way they were in 11.1.0.7 when the GROUPING SETS clause was used in all cases. Note that the two queries are logically equivalent.

Parse XML

how is possible to parse a XML file without using:
javax.xml.parsers.*
org.w3c.dom.*
org.xml.sax.*
thanks...

OK, so why are you asking the question?
Java platforms (version >= 1.4) come with a SAX based XML parser.
SAX XML parsers are freely available as components for use with previous versions.
Alternatively, if you don't want to use SAX, you can download one of the freely available pull-parsers.
If you want to write your own, you can read the spec and write a parser for the grammar. To do that correctly, handiling namespaces and parsed entities is a few weeks work for a good programmer, who understands XML and parsing. In general, this is a waste of time, as the freely available software is of fairly high quality and robustness.
If your application requires XML for compatability, then use one of the technologies you say you want to avoid, or one of the existing alternatives.

Flash Player 10 removes HTML encoding in CDATA when parsing XML

I have an application that was written with Flash Professional 8/AS2 and it parses XML for rendering dynamic media content. The XML pulls text with HTML markup out of CDATA sections and places them into an html enabled text field. Everything has worked wonderfully until Flash Player 10.
Now, if we use html escape characters for greater than or less than symbols, they are being decoded by the xml parser.
Here's my example CDATA section:
Here we go: This <node> <works>
when I grab its value using nodeValue or toString, the results are different from Flash Player 9 to 10. Here's what I'm getting:
node.nodeValue (Flash Player 9):
Here we go: This <node> <works>
node.nodeValue (Flash Player 10):
Here we go: This <node> <works>
node.toString (Flash Player 9):
Here we go: This <node> <works>
node.toString (Flash Player 10):
Here we go: This <node> <works>
In Flash 10, if I escape the ampersand, it will work, but this doesn't work in 9. for example, the following works in 10:
<![CDATA[Here we go: This &#60;node&#62; &lt;works&gt;]]>
This all happens before I assign it to a text field. How do I keep the parser from destroying my escaped characters in Flash 10? Do I just need to drop support for Flash Player 9 and go for what works in 10, or is there a solution for both?

I'm not an action script programmer. I'm just trying to fix some code written like 3 years ago. So I think I am wrong about where this problem is coming from.
The original developer actually set up a class to load a remote xml file via sendAndLoad on a LoadVars object. It passes an object with an onData delegate set that passes the event object to an xml parsing method.
the parsing method looks like this:
 private function parseXml(eventObj:Object){
 if(eventObj != undefined)
 try
 //ExternalInterface.call("logMessage", eventObj.toString());
 _xmlDoc.parseXML(eventObj.toString());
 _xmlDoc.loaded = true;
 _xmlDoc.onLoad(true);
 catch(ex)
 _xmlDoc.onLoad(false);
 else
 _xmlDoc.onLoad(false);
I added the ExternalInterface call so that I could log the stuff out in javascript (since I'm not sure how to debug this app).
_xmlDoc is defined as: private var _xmlDoc:XML;
The eventObj receives the xml string and then passes it to the parseXML thing. Here's the odd part. In Flash Player 10, if I comment out my ExternalInterface call, the xml string has the escaped character decoded before it gets to the parser.
However, if I uncomment my ExternalInterface call, it logs the escaped strings as i would expect, but the parser gets the correct formatting this time! Suddenly it all works.
I really wish I had an AS2 programmer on campus still....

How do i Parsing xml

This how my customers xml is coming across and can not
change.
<month name="January">

<date>01</date>

The above data structure uses a new node for each bit of core
information. It is well laid out and very readable by humans,
however a better structure exists when using Flash. The data
structure below makes more use of the attributes feature, speeding
the parsing process up. It takes longer for Flash to read 6
separate nodes, than it does 6 attributes of a node. The data
structure below is suited better for use with Flash.
How do I get it formated like this?
<month name="January">
<day date="01" name="Thursday" time="12:03 PM" comment="It
is a hot day" />
<day date="05" name="Monday" time="09:28 AM"
comment="Another hot day" />
</month>

Hello again,
Sorry, I thought you wanted to know how to parse XML for this
structure
<month name="January">
<day date="01" name="Thursday" time="12:03 PM" comment="It
is a hot day" />
<day date="05" name="Monday" time="09:28 AM"
comment="Another hot day" />
</month>
This is the one that the code I wrote is using. I think
you're loading in the other one. Doesn't matter - I've included the
for loop for both structures below so that you can try it with
both.

SSMS 2012:FOR XML PATH Using XPath Node Tests-Columnn name 'test()' contains an invalid XML identifier as required by FOR XML?

I feel this xml output is not like the regular xml output. Do you know why it is diffrent from the regular xml xml output? Please comment on this matter.
Thanks,
Scott Chang
What do you mean by regular xml document? Are you referring to fact that its missing a root element? if yes it can be added as below
USE AdventureWorks;
GO
SELECT
p.NameStyle AS "processing-instruction(nameStyle)",
p.BusinessEntityID AS "Person/@ID",
p.ModifiedDate AS "comment()",
pp.PhoneNumber AS "text()",
FirstName AS "Person/Name/First",
MiddleName AS "Person/Name/Middle",
LastName AS "Person/Name/Last",
EmailAddress AS "Person/Email"
FROM Person.Person p
INNER JOIN Person.EmailAddress e
ON p.BusinessEntityID = e.BusinessEntityID
INNER JOIN Person.PersonPhone pp
ON p.BusinessEntityID = pp.BusinessEntityID
FOR XML PATH('ElementName'),ROOT('RootName');
replace ElementName and RootName with whatever name you need to set for element as well as the root element

Problem for using oracle xml parser v2 for 8.1.7

My first posting was messed up. This is re-posting the same question.
Problem for using oracle xml parser v2 for 8.1.7
I have a sylesheet with
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">.
It works fine if I refer this xsl file in xml file as follows:
<?xml-stylesheet type="text/xsl" href="http://...../GN.xsl"?>.
When I use this xsl in pl/sql package, I got
ORA-20100: Error occurred while processing: XSL-1009: Attribute 'xsl:version' not found in 'xsl:stylesheet'.
After I changed name space definition to
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> in xsl file, I got
ORA-20100: Error occurred while processing: XSL-1019: Expected ']' instead of '$'.
I am using xml parser v2 for 8.1.7
Can anyone explain why it happens? What is the solution?

Steve,
We are also creating an XML DOM from java and are having trouble getting the tags created as we want. When we use XMLText it creates the tag as <tagName/>value rather than <tagName>value</tagName>. We want separate open and close tags. Any ideas?

Using XPath for DOM traversal

This question falls into the category of 'I know it's possible, I just need to find the idom in Java'.
I'm coming from a MSFT world were the DOM-centric model of XML processing makes heavy use of XPATH for node selection. Basically using the method element.selectNodes(XPathExpresson) allows one to quickly extract the relevant subset of the parsed tree in the DOM as a nodeList. I've become accustomed to using XML for all strucutured storage that doesn't require a full database.
The W3C DOM Level 3 spec supports evaluateExpression() for this purpose, but I can't believe that Java developers are still using tree traversal waiting for the spec to be implemented. I suppose that I could use getNodesByTagName(), but this is a chainsaw, and I need a scalpel. Anyway, I'm trying to figure out how, exactly, this gets done in Java.
I figure the following are possibilities:
1) It's in JAXP and I missed it
2) One or more of the XML parsers supports XPATH as an extention
3) There's a common package that sits on top of the DOM Document.
4) There's a standard way to apply and XSLT methods to the DOM document
5) Something I've never thought of.
This is a generalized problem for me, so I can't rely on object serialization, Java-XML data mapping, etc. Any guidance would be greatly appreciated.

I've written a Config file reader for XML in java,
and it extracts values using XPath. This is
some of the code you'll need:
imports:
import javax.xml.transform.TransformerException;
import org.w3c.dom.*;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.apache.xerces.parsers.DOMParser;
import org.apache.xpath.XPathAPI;
import org.apache.xpath.objects.*;
Document doc=....;
* returns a single DOM Node from the config file.
public Node getNode(String xpath) throws ConfigException {
try {
return XPathAPI.selectSingleNode(doc, xpath);
} catch (TransformerException e) {
throw new ConfigException("Can't find '"+xpath+"' ("+e.getMessage()+")");
