Number of elements in XML file
Hi,
I have an xml file as follows
<xml>
<head>
<h1>xxxx</h1>
</head>
<line>
<name>ravi</name>
<dept>Oracle</dept>
</line>
<line>
<name>Kamal</name>
<dept>Java</dept>
</line>
<line>
<name>Ajay</name>
<dept>Linux</dept>
</line>
</xml>
I need to insert the above xml file into a table.
For that i have used the following query.
insert into dest_table
SELECT EXTRACTVALUE (t2.xml_doc, '/xml/head/h1') head,
EXTRACTVALUE (t2.xml_doc, '/xml/line['||level||']/name') name,
EXTRACTVALUE (t2.xml_doc, '/xml/line['||level||']/dept')dept
FROM xml_table t2
CONNECT BY LEVEL <= n
Here n in CONNECT BY clause is the number "<line>" elements (3 in the above example).
If i know the number of <LINE> elements,then i can easily select and insert the xml data.
BUT How to know the number of particular elements(<line> in above xml) in the above xml using oracle xml oracle.
any idea psl.
cheers
RRK
select count(1) from table(
xmlsequence(
extract(
XMLType('<root><a>b</a><a>c</a><a>d</a><x>z</x></root>'),
'/root/a'
)

</printing>How do i do it using DOM,
I can create instance of DOM and write it using TransformerFactory
AshishHi
I am trying the following code,
but it is not working
NodeList nScene = doc.getElementsByTagName("firstLineTexts");
NodeList nScene1 = nScene.item(0).getChildNodes();
for (int i = 0; i < nScene1.getLength(); i++)
Node n = nScene1.item(i);

How to add attribute to the elements in XML file in BPEL transformation
Hi All-
I have to create a XML file using transformation and file adapater and the parent element is USERRECORDS, now when I am creating the XML file using transformation the XML get creates like
<?xml version="1.0">
<USERRECORDS>
so on
But I want the parent element and the xml version tags as:
<?xml version="1.0" encoding="UTF-8"?>
<USERRECORDS xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="mySchema.xsd">
as I need to add the attributes.
Is it possible in transformation?
Any idea, please suggest.
Thanks and Regards,
SreejitI have never come across any functionality like that.
However I assigned values to attributes in Assign Acitivity using XML Fragment on source side. -
Number of elements in TDMS file
Is there a way to determine the number of elements in a TDMS file? The files I am creating have several signals all of the same length. The only way I can think of is to do this is put it in a loop and read one element at a time until it reaches the end of the file. But, my files will have millions of elements. Any suggestions?
Thanks.
--RobertThanks Herbert
For readers having similar problems, here are my experiences:
It works either without wiring a property name and datatype, as you mentionned before.
Resulting is a variant array. Result see attached solutionVariant.jpg
It also works wiring the right datatype as in the TDMS File Viewer and your first explanations:
Resulting is the channel length as Integer I64 or U64. Datatype constant representation and indicator representation must match!
See attached solution.jpg
My error has been wiring a string "I64" as datatype and a string indicator as value indicator. So stupid...

Invalid tag generated in result XML file, xslt mapping done using MAPFORCE
HI
My requirement is File to File using xslt mapping
I have done a very simple XSLT mapping, but through MAPFORCE tool
Here are the steps, I followed:
1. Supplied source xsd and xml file to MAPFORCE
2. Supplied target xsd file
3. mapped it as required
4. tested by supplying a sample xml file by clicking OUTPUT button, which displays perfect XML structure
5. Clicked XSLT button and copied and created a new file with extension .xsl file
6. Zipped the above xsl file
7. imported into IR imported archives folder
8. Selected the above xslt mapping in my Interface mapping.
9. Now tested my Interface Mapping by supplying sample some data for the source structure.
Now I got the error or warning "XML not well-formed" and got the successfull completion message window for my mapping when I proceed.
Now when I clicked xml source button for the target structure, It displays the invalid tag and starting with "#default"
So If I removed this particular tag at the first and last lines, it becomes a valid xml structure and able to see properly in my internet explorer
Here is the result I am getting:
<?xml version="1.0" encoding="UTF-8"?>
<#default:MT_Student_Result xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:xsltMappingScenarios C:/DOCUME~1/Satya/Desktop/MT_Student_Result.xsd">
<Data>
<Name>Khan Raj</Name>
<Marks>
<Total_Marks>166</Total_Marks>
</Marks>
</Data>
</#default:MT_Student_Result>
When I tested through MAPFORCE it generates absolutely valid XML structure when I clicked OUTPUT button on MAPFORCE, but not when I used the xslt mapping through my interface mapping.
What is the error I am making or any step missing?
Please help me!

Edited by: Shilpa Shetty on Oct 9, 2008 5:58 AM
Edited by: Chris Rock on Oct 9, 2008 6:06 AMFor some reason when I use MapForce tool to generate my xslt mapping source, it is generating the following statement in the xsl file.
<xsl:namespace-alias stylesheet-prefix="n" result-prefix="#default"/>
So at the root element of XML file, it is replacing the character n with '#default' for some reason, I don;t know the purpose of this.
As you suggested, I changed the name space, still I experienced same problem.
It is now resolved after removing the above xsl statement from the xsl file before creating/uploading the relevant zip file into archives folder.
It works fine now. Thanks for the clue. -
CS4-JS : Read XML file and getting Attributes
Dear All,
How to get the Attributes based on the RootElements.
For Example:
//========================== XML File : Start ================================//
<stag>
<cust>
<custname>120</custname>
<atagst name="alpha" attributename="1" attributevalue="2" sty="First"/>
<atagst name="beta" attributename="1" attributevalue="5" sty="Second"/>
<atagst name="gama" attributename="1" attributevalue="2" sty="Third"/>
<atagst name="theta" attributename="1" attributevalue="5" sty="Fourth"/>
<cust>
<cust>
<custname>121</custname>
<atagst name="A.alpha" attributename="1" attributevalue="2" sty="First"/>
<atagst name="A.beta" attributename="1" attributevalue="5" sty="Second"/>
<atagst name="A.gama" attributename="1" attributevalue="2" sty="Third"/>
<atagst name="A.theta" attributename="1" attributevalue="5" sty="Fourth"/>
<cust>
<cust>
<custname>122</custname>
<atagst name="B.alpha" attributename="1" attributevalue="2" sty="First"/>
<atagst name="Bbeta" attributename="1" attributevalue="5" sty="Second"/>
<atagst name="B.gama" attributename="1" attributevalue="2" sty="Third"/>
<atagst name="B.theta" attributename="1" attributevalue="5" sty="Fourth"/>
<cust>
</stag>
//========================== XML File : End ================================//
Here I want to check through Java Script Code [InDesign]
//======================== Script : Starts ====================================//
var myEveryName = new Array();
traverse(roots);
for(var Element_name=0; Element_name<myEveryName.length; Element_name++)
if(myEveryName[Element_name] == "customername")
custname.push(myEveryContent[Element_name]);
if(myEveryName[Element_name] == "applytagstyle")
Aname.push(myEveryAttributes[Element_name][0]);
Aattributename.push(myEveryAttributes[Element_name][1]);
Aattributevalue.push(myEveryAttributes[Element_name][2]);
Asty.push(myEveryAttributes[Element_name][3]);
function traverse(tree) {
myEveryName.push(tree.name());
if(tree.elements().length() > 0) {
for(var i=0; i<tree.elements().length(); i++) {
traverse(tree.elements()[i]);
//======================== XML File : End ====================================//
Everything working fine, but I couldn't get attribute values. Please check the below example
For Example:
If you check first root element in above xml code
i need the output like
custname=120
name=alpha,beta,gama,theta
attributename=1,1,1,1
attributevalue=2,5,2,5
sty=first,second,third,fourth
custname=121
Please any one can help me and give me the solutions.
Thanks & Regards
T.R.Harihara SudhaNFew questions:
1. Your XML is not well formed.
2. Secondly, I do not see any relation of XML with script. For instance, I do see any elements "customername", "applytagstyle" in input.
3. Either you have not provided the complete source or either your dummy XML is incorrect.
Anyways, having a quick look, I guess you are trying to get specific attributes values from XML tree. I will try to give you a kick start though you will be required to customized the script as per requirement (for instance rearranging the attribute values in array and so forth). Otherwise please try to post complete inputs.
#include "glue code.jsx"
//Get the attribute values of all elements
main();
function main(){
if (app.documents.length != 0){
var myDoc = app.activeDocument;
var myRuleSet = new Array (
new findObjAttribute("//*")
with(myDoc){
var elements = xmlElements;
__processRuleSet(elements.item(0), myRuleSet);
else{
alert("You have no document open!");
exit();
function findObjAttribute(XPATH){
this.name = "findObjAttribute";
this.xpath = XPATH;
this.apply = function(myElement, myRuleProcessor)
var elmName=myElement.markupTag.name;
with(myElement){
try {
var Name=myElement.xmlAttributes.itemByName("name").value;
var AttName=myElement.xmlAttributes.itemByName("attributename").value;
var AttValue=myElement.xmlAttributes.itemByName("attributevalue").value;
var AttSty=myElement.xmlAttributes.itemByName("sty").value;
$.writeln("Name: "+Name);
$.writeln("AttributeName: "+AttName);
$.writeln("AttributeValue: "+AttValue);
$.writeln("Sty: "+AttSty);
} catch(e){};
return true;
This will just print the values JavaScript console.

Hi,
I'm going to use JAXP and SAX to read my application XML config file.
But I'm lost, I don't know how to read the elements.
How does it function, do I have to put in the startElement() method as many "if" as entitys I need to process?
And how can I guess if an element belongs (is inside) one element or another?
Example:
<program>
<printer id="xx" type="aa">
<path> /aa/cc </path>
</printer>
<source>
<path> /aa/bb </path>
</source>
</program>
for this XML, how would you code it? this way?
startElement (String uri, String localName, String qName, Attributes attributes) {
if (localname.equals("printer")) {
//get printer attributes
} else if (localname.equals("source")) {
//get source attributes
thanks!i have one sample code through which u can read the elements from xml file.

Loading data held in separate XML files
I think I am probably just having a slow brain day, but I have a requirement that I can't think of a neat solution for.
We will be receiving a number (200-400 ish) xml files twice a day. These files will have a standard naming structure - 850xxxx_ATT_850LLLL_zzz.xml
xxx will be a 4 digit school number - we will get a file for each school twice a day and yyy is a numeric identifier. The identifiers won't necessarily be consecutive for a particular school, they will in general be increasing, but they will wrap around eventually (only a 3 digit number)
I want to merge all of the data into a table, twice a day, the details for an existing row can be updated and new ones inserted. Once I have the data in oracle I can then process it however I like, I'm comfortable with that bit. It's loading the data I'm not sure about
database version is
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Prod
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for 32-bit Windows: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
running on Windows Server 2003
I'd prefer a mainly oracle based solution if possible. Otherwise I could just loop through the files programatically, strip the data out via XPATH or using some sort of DOM and then do a series of insert/updates. Getting messy though and I would prefer to keep the loading of the data with the processing of the data.
Any suggestions? A gentle Nudge in the right direction should do it - I'm happy to work out the details (Which is why I haven't gone into the details of the XML or the data)

my db version is Oracle Database 10g Release 10.2.0.1.0 - ProductionHi,
What are you trying to achieve with a single WITH clause and no SELECT?
Please see this from the documentation if you want to use it properly :
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_10002.htm#i2077142
Apart from its true purpose of subquery factoring, the WITH clause is often use here and there to simulate a table content, but you'll always need a SELECT.
Maybe that's what you were trying to do?
As for your question, starting with release 10.2, Oracle provides XMLTable to shred XML documents into relational structures.
For example,
with t as (
select xmltype('<Message-Header>
<Message-Id>1234</Message-Id>
<Sender-Company-ID>4569</Sender-Company-ID>
<Sender-Company-Name>abc company</Sender-Company-Name>
<Sender-User-ID>AA</Sender-User-ID>
<Recv-Company-ID>050</Recv-Company-ID>
<Recv-Company-Name>XYZ pvt.ltd</Recv-Company-Name>
<Creation-Time>20101019 15:59:39</Creation-Time>

;If you're working in PL/SQL, and the XML resides in a variable, you can directly do (with necessary datatype conversion in the SELECT) :

Vendor code 30951Error at Line:18I would guess that some of the fields have max lengths > 4000. I plan to annotate the schema with SQLType="CLOB", but need to know which fields to change. I was able to copy the xml file and reduce that xml file to one record, which imported into the tables. My plan was to write a view over the bfile to get the lengths of certain fields, annotate the .xsd with CLOBS where needed, and then import again. In order to do that, I have a 1 record file imported into a table and as a bfile.
Here is my code selecting length from a generated object-relational table of only one record.
CREATE OR REPLACE VIEW pharma.drugs_vw AS
SELECT d.*
FROM drugs, XMLTABLE
('/drugs' PASSING OBJECT_VALUE COLUMNS
drugbank_id VARCHAR2(20) PATH 'drug/drugbank-id',
name VARCHAR2(50) PATH 'drug/name',
description VARCHAR2(4000) PATH 'drug/description'
) d
select max(length(drugbank_id)) as dbidlen,
max(length(name)) as nmlen,
max(length(description)) as desclen
from drugs_vw;
DBIDLEN NMLEN DESCLEN
7 9 229
1 row selected.Here is the code for the bfile. Same results, but using deprecated functions. I read the whitepaper, Oracle XML DB: Best practices to get optimal performance out of XML Queries. It says that extract(), extractvalue(), Table(XMLSequence()), and XMLType() are deprecated in 11gr2.
-- Note extractvalue is deprecated in 11gr2 replaced by W3C standard
-- XMLCast(XMLQuery())
-- TABLE(XMLSequence) is replaced by XMLTable
-- XMLType() is replaced by XMLParse()
SELECT max(length(extractvalue(column_value, '/drug/drugbank-id'))) dbidlen,
max(length(extractvalue(column_value, '/drug/name'))) nmlen,
max(length(extractvalue(column_value, '/drug/description'))) desclen
FROM TABLE(XMLSequence(XMLTYPE(bfilename('XMLPHARMA',
'db00001.xml'),nls_charset_id('AL32UTF8')).extract('/drugs/drug'))) d
WHERE ROWNUM <= 5;
DBIDLEN NMLEN DESCLEN
7 9 229Is this better code for getting the maximum length of xml fields from a bfile? Here is what I have so far. This works on a single drugbank-id.
SELECT max(length(drugbank_id)) AS dbidlen,
max(length(name)) AS nmlen,
max(length(description)) AS desclen
FROM (XMLTABLE('*'
PASSING (XMLType(bfilename('XMLPHARMA', 'db00001.xml'),nls_charset_id('AL32UTF8')))
COLUMNS
drugbank_id VARCHAR2(20) PATH 'drug/drugbank-id',
name VARCHAR2(50) PATH 'drug/name',
description VARCHAR2(4000) PATH 'drug/description'
);I try to run it on the full file and get this error
Error report:
SQL Error: ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00007: unexpected end-of-file encountered
31011. 00000 - "XML parsing failed"
*Cause: XML parser returned an error while trying to parse the document.
*Action: Check if the document to be parsed is valid.The code to create schema and object-relational tables. This worked fine.

but the problem is i want to read (parse) any XML file means any Elemets would be change any time using SAX .In the above example
else if (elemName.equals("Heat")) {
else if (elemName.equals("IndexREDId")){
} else if (elemName.equals("Maturity")) {
like above I am doing hard code Elements names and reading the values so i don't want hard coding the elements names I want to read any element name and value dynamically.
If i give any one below XML file i want to read the Elements and displaying to console without changing any code i want to read the XML document.
EX:
Student.XML: <root>..</StName>..</StAge>...</root>
Employee.XML: <root>..</EmpName>..</EmpAge>...</root>
CdCatalog.XML: <root>..</Cdtitle>...</CdNumber>...</root>
I need one java program can ready any type of XML file elements and send to the Database table.
Please any one done like this task please suggest some reference links or books or sample snippet which can help me to develop program in my requirement.
Thanks in advance

satishYou should ask in the Java forum.

Instance variable to hold the element of a tag in the xml file
Hi I have an xml file that is handled using this parser
<attr id="MY_NAME" >
this parser hanled the above tag but now I want to have it handle
<attr id="MY_NAME" desc="GOOD">
but I need to create an instance variable to handle the desc element in the attr tag .
Can some one help me out as this is not my file and I am having trouble to do please......

The SupportMatrix class provides static variables and methods to simplify
the determination of whether or not a given attribute is supported for a
certain object type (queue manager, channel, etc.), depending on the version
and platform of the queue manager to which it belongs.
The SupportMatrix class may not be instantiated. Its constructor is private.
An instance of the class is created internally in the static initializer so
that the XML parsing methods are available.
A corresponding XML document, SupportMatrix.xml, is parsed to create the various
HashMaps which contain the version/platform dependency information. A number of
inner classes are used to represent the various elements of the XML matrix
definition.
Here's a sample document:
<!-- The supportmatrix tag opens the document -->
<supportmatrix>
<!-- Objects are keyed by classid. "1" is the classid of a queue manager object. -->
<object classid="1">
<!-- Versions group attributes according to the queue manager version where they
were introduced. The "base" cmdlevel encompasses all versions up to 5.1. -->
<version cmdlevel="base">
<!-- Attributes are defined by the attr tag. -->
<attr id="MQCA_Q_MGR_NAME">
<!-- Support elements define the platform-specific requirements for an attribute. -->
<support platforms="UNIX,WINDOWS,OS400,VMS,NSK" maxlen="48" type="MQCFST"/>
<support platforms="MVS" maxlen="4" type="MQCFST"/>
</attr>
<attr id="MQCA_Q_MGR_DESC">
<!-- Specific attribute characteristics, most notably maximum len for string parms,
are defined in the support element. As shown in the following example, it may
apply to all platforms. -->
<support platforms="all" maxlen="64" type="MQCFST"/>
</attr>
<!-- Support elements are optional. -->
<attr id="MQIA_PLATFORM"/>
<attr id="MQIA_COMMAND_LEVEL"/>
</version>
<!-- The version element may 'include' other versions. Note that object elements
may also refer to other objects via the 'include' parm of the object tag.
This is to allow common attributes (especially for queues and channels) to
be shared by multiple definitions in order to reduce some of the
redundancy. -->
<version cmdlevel="520" include="base">
</version>
</object>
</supportmatrix>
The inner classes, and their hierarchical relationships are as follows:
SupportObject - corresponds to the <object> element. Stored in a static HashMap, and
keyed by classid.
VersionObject - corresponds to the <version> element. Stored in a HashMap instance
variable of the SupportObject class, keyed by cmdlevel.
AttributeObject - corresponds to the <attr> element. Stored in a HashMap instance
variable of the VersionObject class, keyed by attribute name.
PlatformObject - corresponds to the <support> element. Stored in HashMaps belonging
to the AttributeObjects, keyed by platform. A single PlatformObject
instance is created when the support tag is encountered. The
"platforms" attribute of the support element is then processed. For
each platform in the comma-delimited list, an entry is added to the
collection of PlatformObjects. This is to greatly simplify later
lookups.
In order to support the 'include' feature of object and version elements, certain
functions are recursive. If the attribute to be validated is not found for the passed
cmdlevel, the 'parent' VersionObject is consulted by means of the 'include' value. If
the chain of VersionObjects has been exhausted and the attribute in question has still not
been located, the next SupportObject in the chain is consulted in a similar fashion.

}Are you the one who commented out the code you're looking for ?//String desc = StringFactory.getString(attributes.getValue("desc"));You just have to modify you AttributeObject class to hold a new field : String description. And then, it's up to you to create a new constructor or a new setter method.
Btw, this is not a Swing related question.
