Node / element in XML
I have one XML message with an element <netvmi.edi>, but in IR is not possible to create a data type with this name because ite contain a character invalid (.). How I to solve it?
Hi Elton,
if you dont use a message mapping (you can use XSL, Java or ABAP) and no proxy or BPM container, dont care about that. The interfaces are not processed during runtime. Give us a short description of your scenario (adapters, sychronous?, BPM?) for a better help.
Regards,
Udo

Store XML node value into an array with node element name
Hi,
I have the following code that displays the node element with the
corresponding node value. I want to store the values in an array in
reference to the node name.
i.e.
XML (my xml is much bigger than this, 300 elements):
<stock>
<symbol>SUNW</symbol>
<price>17.1</price>
</stock>-----
would store the following:
*data[symbol] = SUNW;*
*data[price] = 17.1;*
Thanks in advance,
Tony

I've done the following but its not working, i'm getting error codes. I think its an easy fix. I'd also like to pass a String instead of a .xml document b/c my xml is stored inside a DB. Any suggestions on that?

Adding multiple same-name nodes from one xml into another
Hi,
Following on from my question the other day (Adding multiple different nodes from one xmltype into another), I now have a slightly more complex requirement that I cannot work out where to start, assuming that it's something that can reuse some/all of yesterday's work (thanks again, odie_63!). ETA: I'm on 11.2.0.3
So, here's the (slightly amended) xml along with yesterday's solution:
with sample_data as (select xmltype('<root>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
</xmlnode>
</root>') xml_to_update,
xmltype('<a>
<b>valb</b>
<c>valc</c>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<e>vale</e>
<f>valf</f>
<g>
<g1>valg1</g1>
<g2>valg2</g2>
</g>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
<multinode>
<name>fred</name>
<type>book</type>
<head>1</head>
</multinode>
<multinode>
<name>bob</name>
<type>car</type>
<head>0</head>
</multinode>
</a>') xml_to_extract_from
from dual)
select xmlserialize(document
xmlquery(
'copy $d := $old
modify (
insert node element extrainfo {
$new/a/b
, $new/a/d
, $new/a/f
, $new/a/h
} as first into $d/root
return $d'
passing sd.xml_to_update as "old"
, sd.xml_to_extract_from as "new"
returning content
indent
from sample_data sd;
That gives me:
<root>
<extrainfo>
<b>valb</b>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<f>valf</f>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
</extrainfo>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
</xmlnode>
</root>
However, I now need to add in a set of new nodes based on information from the <multinode> nodes, something like:
<root>
<extrainfo>
<b>valb</b>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<f>valf</f>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
<newnode>
<name>fred</name>
<type>book</type>
</newnode>
<newnode>
<name>bob</name>
<type>car</type>
</newnode>
</extrainfo>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
<type>book</type>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
<type>car</type>
</xmlnode>
</root>
If it's easier, I *think* we would be ok with something like:
<newnode>
<type name="fred">book</type>
<type name="bob">car</type>
</newnode>
The closest I've come is:
with sample_data as (select xmltype('<root>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
</xmlnode>
</root>') xml_to_update,
xmltype('<a>
<b>valb</b>
<c>valc</c>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<e>vale</e>
<f>valf</f>
<g>
<g1>valg1</g1>
<g2>valg2</g2>
</g>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
<multinode>
<name>fred</name>
<type>book</type>
<head>1</head>
</multinode>
<multinode>
<name>bob</name>
<type>car</type>
<head>0</head>
</multinode>
</a>') xml_to_extract_from
from dual)
select xmlserialize(document
xmlquery(
'copy $d := $old

$new/a/b
, $new/a/d
, $new/a/f

, element newnode {

,$new/a/multinode/type
} as first into $d/root
return $d'
passing sd.xml_to_update as "old"
, sd.xml_to_extract_from as "new"
returning content
indent
) fred
from sample_data sd;
Which produces:
<newnode>
<name>fred</name>
<name>bob</name>
<type>book</type>
<type>car</type>
</newnode>
- obviously not right!
Can anyone provide any hints? I've tried searching for similar examples, but I mustn't be putting in the right search terms or something!odie_63 wrote:

So we're going with the second method, but I've discovered that the "$i/name" node is not always present. When that happens, I would like to use a default value (for example, "george"). I promise I've searched and searched, but I'm completely failing to turn up anything that sounds remotely like what I'm after (seriously, I can't believe my google-fu sucks this badly!).
Is there a simple way of doing it? The only thing that I've found that looks vaguely relevant is "declare default namespace...." but I'm not sure that that's the correct thing to use, or if it is, how I'm supposed to reference it when populating the attribute value. -
How to get the second element in XML Response with same name
Hi All,
I am struck at this point, I have written a sample HTTP client which sends a request to the HTTP Server. In response to the request made the HTTP Server gives response in the XML format. eg: -
<?xml version="1.0"?>
<parent>
<node1> Value1 </node1>
<node1> Value2 </node1>
<node2> Value3 </node2>
</parent>
In the HTTP Client I am getting the value of node1 using the following statement: -
if (node instanceof Element && "node1".equals(((Element)node).getName()) )
String node1 = node.getStringValue();
System.out.println("Product Code:"+node1);
This is always returning the first node1 value i.e. <node1> Value1 </node1>.
The requirement is, I also need to get the <node1> Value2 </node1> value also. So can anyone tell me hw can I get the <node1> Value2 </node1> value. please tell me the piece of code that I should add to get the <node1> Value2 </node1>.
My Mode is something like this: -
try
Document document = (Document)DocumentHelper.parseText(response);
List<Node> transactionNodeList = document.selectNodes( "//parent" );
for(Node singleNode:transactionNodeList)
for(int i=0,j=0;i< ((Element)singleNode).nodeCount();i++ )
Node node = ((Element)singleNode).node(i);
if (node instanceof Element && "node1".equals(((Element)node).getName()) )
node1= node.getStringValue();
System.out.println("Air Way Bill Number:"+node1);
if (node instanceof Element && "node1".equals(((Element)node).getName()) )
node1= node.getStringValue();
System.out.println("Product Code:"+node1);

Waiting for your replay.
Thanks in Advance
Best regardHi,
Till now i tried the following code which give null pointer exception at following line
element.getParentNode().removeChild(element);
public String removeUserByID(String id) throws Exception{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer tFormer = tFactory.newTransformer();
doc = builder.parse(usersXml);
Element element = (Element)doc.getElementsByTagName("user id="+id).item(0);
// Remove the node
element.getParentNode().removeChild(element);
// Normalize the DOM tree to combine all adjacent nodes
doc.normalize();
FileOutputStream fos = new FileOutputStream(this.usersXml);
XMLOutputter out = new XMLOutputter();
out.output(((org.jdom.Document)doc), fos);
/* Source source = new DOMSource(doc);
Result dest = new StreamResult(System.out);
tFormer.transform(source, dest);
System.out.println();
return "true";
if following line i m trying to use first attribute of my XML file where i am passing a string which is for example like "user id=Guest". id is a string which have user Id "Guest".
Element element = (Element)doc.getElementsByTagName("user id="+id).item(0);So any suggestion??Whats wrong here?

Edited by: chinnasapxi on Mar 16, 2010 8:11 PMHi Chinna,
Probably writing a script and calling in receiver file adapter after message processing and in the script just add the line in the 3rd line and then put the rest.

Thanks in Advance.It goes something like this, taken from the above blog entry:
Removing a node from node-list
With the bpelx: extensions in BPEL you are able to insert and update nodes in a node list. A node-list is an XML message that contains a set of records. In this article I use the following example:
<BookList xmlns="http://message.vijfhuizen.com">
<Book>
<title>The Lord Of The Rings</title>
<author>J.R.R. Tolkien</author>
</Book>
<Book>
<title>Harry Potter</title>
<author>J.R.R. Tolkien</author>
</Book>
<Book>
<title>The Hobbit</title>
<author>J.R.R. Tolkien</author>
</Book>
<Book>
<title>Storm; Chronicals of Pandarve</title>
<author>Don Lawrence</author>
</Book>
</BookList>
For creating and updating node lists the bpelx: functions are enough to handle this. But when you want to remove a particular node, you can use the bpelx:remove function. But this function can only remove a node from a particular position. For example removing the second node you code:
<bpel:assign>
<bpelx:remove>
<bpelx:target variable="VarBookList" query="/Booklist/Book[2]" />
</bpelx:append>
</bpel:assign>
It is hard to code the bpelx:remove to create a xpath to dynamicly remove node. You would like to remove the second node based on the xpath:
/Booklist/Book[title="Harry Potter" and author="J.R.R. Tolkien"]
You can add the above xpath in the bpelx:remove, but you are not able to make this dynamically.
There is a solution. The trick is to create a stylesheet that copies the data into a new message, but removing that particular records. Create a stylesheet that does the normal copy of the XML message. Then add a <choose> element in the stylsheet to filter that particular record.
<xsl:template match="/">
<BookList>
<xsl:for-each select="/BookList/Book">
<xsl:choose>
<xsl:when test="title='Harry Potter' and author='J.R.R. Tolkien'"/>
<xsl:otherwise>
<Book>
<title>
<xsl:value-of select="title"/>
</title>
<author>
<xsl:value-of select="author"/>
</author>
</Book>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</BookList>
Now we have a XSL stylesheet that removes a particular record, but this is not variable. This can be done via XSLT parameters.
<xsl:param name="pTitle"/>
<xsl:param name="pAuthor"/>
<xsl:template match="/">
<BookList>
<xsl:for-each select="/BookList/Book">
<xsl:choose>
<xsl:when test="title=$pTitle and author=$pAuthor"/>
<xsl:otherwise>
<Book>
<title>
<xsl:value-of select="title"/>
</title>
<author>
<xsl:value-of select="author"/>
</author>
</Book>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</BookList>
</xsl:template>
Now we are able to use this stylesheet in BPEL. In general BPEL create the following code:
<assign name="Transform">
<bpelx:annotation>
<bpelx:pattern>transformation</bpelx:pattern>
</bpelx:annotation>
<copy>
<from expression="ora:processXSLT('RemoveNode.xsl'
, bpws:getVariableData('Variable_BookList','payload')" />
<to variable="Variable_BookListTemp" part="payload"/>
</copy>
</assign>
But this code does not pass parameters to the stylesheet. The ora:processXSLT() can do this it has an additional parameter in this function:
<assign name="Transform">
<bpelx:annotation>
<bpelx:pattern>transformation</bpelx:pattern>
</bpelx:annotation>
<copy>
<from expression="ora:processXSLT('RemoveNode.xsl'
, bpws:getVariableData('Variable_BookList','payload')" />
, bpws:getVariableData('BPELxslparameters'))"/>
<to variable="Variable_BookListTemp" part="payload"/>
</copy>
</assign>
Now only you have to create the BPELxslparameters variable and assign it with the correct name/value pairs. The structure of the this variable is as follows:
<?xml version="1.0" encoding="windows-1252" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://schemas.oracle.com/service/bpel/common"
targetNamespace="http://schemas.oracle.com/service/bpel/common"
elementFormDefault="qualified">
<xsd:element name="parameters">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="item" minOccurs="1" maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="name" type="xsd:string"/>
<xsd:element name="value" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
Create in BPEL the variable BPELxslparameters and let it point to this strucure:
<process ....
xmlns:common="http://schemas.oracle.com/service/bpel/common"
.../>
<variable name="BPELparameters" element="common:parameters"/>
Now we can in BPEL create an empty XML message, based on this strcuture and assign the values to these parameters and then call the processXSLT function.
<bpelx:assign name="Assign_GenerateEmptyParameterSet">
<copy>
<from>
<parameters xmlns="http://schemas.oracle.com/service/bpel/common">
<item>
<name>pTitle</name>
<value/>
</item>
<item>
<name>pAutor</name>
<value/>
</item>
</parameters>
</from>
<to variable="BPELparameters" query="/common:parameters"/>
</copy>
</bpelx:assign>
<assign name="Assign_setXSLTParameters">
<copy>
<from expression="'Harry Potter'"/>
<to variable="BPELparameters" query="/common:parameters/common:item[1]/common:value"/>
</copy>
<copy>
<from expression="'J.R.R. Tolkien'"/>
<to variable="BPELparameters" query="/common:parameters/common:item[1]/common:value"/>
</copy>
</assign>

Node refnum comparison (XML parser)
Hello,
I am trying to parse an XML document (actually an Open Office doc) with the LabVIEW 2009 built-in XML Parser. My problem is to identify if two Nodes are actually refering to the same point in the XML or not. For example:
I do a search for specific table cells. The result is an array of Nodes. I want to know if they are on the same table row. So I go up to the first "table row" parent, of which I get the reference. Now I would like to compare two of these parent "row" references, to check if they refer to the same table row. Use of the "equal" LabVIEW function seems not to work (always pretends the reference is different, even if pointing to the same table row actually).
Any idea ?
VincentHello,
Thank you for your interest for the topic. Here is a small example, which is described here:
Assume you have an XML with following content:
<XML>
<Parent>
<Child name="A1">
<Feature />
</Child>
<Child name="A2">
<NoFeature />
</Child>
</Parent>
<Parent>
<Child name="B1">
<Feature />
</Child>
<Child name="B2">
<NoFeature />
</Child>
</Parent>
</XML>
Let's say I need to find all the <Feature> nodes and check whether or not they belong to the same <Parent>. If I look for all the <Feature> nodes by sequentially parsing the whole XML (with a combination of "Next Sibling" and "Next Child" navigation), I will certainly know when I switch from one <Parent> instance to the other one, but this is very inefficient for large XML. I have chosen to use the following method instead:
- with the "Get Elements by Tag Name Array" method for the XML document (DUXGetElementsByTagName), I get an array of all the <Feature> nodes in the document. These are node references to <Child name="A1"/> and <Child name="B2"/> in the above example.
- from both of these nodes I go up to successive parents until I find the <Parent> node reference.
- now I have two different references to <Parent> nodes. I am almost over, I just need to check whether these are the same <Parent> node, or if they are different instances of a <Parent> node (as it is the case in the above example).
How can I do this last step ? Comparing the node references directly with the general "Equal?" built-in LabVIEW function does not work (result is always FALSE, even if both node references point to the same node instance). What is missing here is a sort of "IsSameNode" method, with two node references as inputs, and a boolean as output, that would just return TRUE if both references are pointing to the same node in the XML...
Hope this helps.
Best regards,
Vincent

Unmarshalling a DOM node to an XML file with JAXB
I'm trying to unmarshall a DOM node to an XML file using JAXB. However I keep receiving a NullPointerException. This only seems to occur when I create the DOM Node from scratch. The stack trace looks like the following:
java.lang.NullPointerException
at com.sun.xml.bind.unmarshaller.SAXUnmarshallerHandlerImpl.startElement
(SAXUnmarshallerHandlerImpl.java:87)
at com.sun.xml.bind.unmarshaller.DOMScanner.visit(DOMScanner.java:109)

Impl.java:149)
at Main.main(Main.java:103)(If I unmarshal an XML file into a DOM node, I can successfully marshall the DOM node out to a new XML file using JAXB without error.)
Any insight into what I am doing wrong would be greatly appreciated!

Hello guys,
Can somebody help me???
I need all nodes of one xml that <system> element
equals "SystemOne".
private function initApp():void {
var xmlTemp:XML =

<xinterface>
<name>firstInterface</name>
<team>TeamOne</team>
<systems>
<system>
<name>SystemOne</name>
</system>

<name>SystemThree</name>
</system>
</systems>
</xinterface>
</interfaces>;
var xmlFind:XML =
xmlTemp.xinterface.systems.system.(name=='SystemOne').parent().parent();
But this don't work... return error (TypeError: Error #1010:
A term is undefined and has no properties.)
Thank a lot!!!
KleberNo ready made example, but maybe some (untested) snippets.
var xlSystem:XMLList =
xmlTemp.xinterface.systems.system.(name=='SystemOne');
var xmlInterface:XML = <foundinterfaces />;
var xmlInterface:XML;
for (vari:int=0;i<xlSystem.length();i++) {
xmlInterface = xlSystem
.parent().parent();
xmlInterface.appendChild(xmlInterface .copy());

How to pass all values from one node element to created node element?
Hi
I have model node element under which there are 7 values, and I've created value node element and trying to pass the values from the model node Element to this value node element. But instead of passing all the values its listing only one value.
How do we rectify this problem!!!
Thanks in Advance
SrikantHi Anil
I've created the node named: TableNode
and the name of the node from which i want to get the data is : Li_Required_Node
the Node Structure is
Context
|_ Zs_Quantity_Input
|_Output
|_Node_Required_Node
|_Schddt
|_TableNode
|_CmpDate
The Schddt has some 7 values
The code Snippet is as follows:
IPublicPricesComp.ITableNodeElement nodeElement;
IPublicPricesComp.ILi_Required_NodeElement scheduleElement;
int counter3Max = wdContext.ILi_Required_Node().size();
for( int counter3= 0 ; counter3 < counter3Max ;counter3++ )
nodeElement = wdContext.createTableNodeElement();
scheduleElement = wdContext.nodeZs_Quantity_Input().nodeOutput_Contract_Qty().nodeLi_Required_Node().getLi_Required_NodeElementAt(counter3);
nodeElement.setCmpDate(scheduleElement.getSchddt());
wdContext.nodeTableNode().addElement(nodeElement);
On writing the above code and then binding the node to a table column only one value getting displayed
Where can be the error?
Thanks in Advance

How to delete a node in an XML document
Hi,
My flex plugin loads an XML document that is passed in from
the ExternalInterace. I have a List control that displays data from
this XML document.
The XML looks like:
<document>
<response>
<objectlist>
<list type="typeValue">
<object type="typeValue" name="Name Value" id="GUID
Value1">
<params>
<params>
</object>
<!-- more objects in this list -->
</list>
</objectlist>
</response>
</document>
I set the list dataProvider to
xmlDoc.response.objectlist.list.object
Thing is, I want to remove one of the object nodes before I
display the data (that is, i dont want one of the nodes in the XML
document to appear in the list).
How do I do this? I could not find any way to delete an
existing node in the XML api.
-GauravYou can either use the "delete" operator:
delete xmlDoc.response.objectlist.list.object[5]
where the object to be deleted might be the fifth down
(you'll have to play with your xml in debug to get the actual
values down) or convert to xmlListCollection. The xmlListCollection
provides easy methods to remove the offending nodes or you may
provide a filterFunction for the collection which will "hide" the
node. -

Why we need to conver Context Node data into XML file----Export to Excel
Hi All,
Let me clarify my dought........today i have gone through the concept of "Exporting Context Data Using the Webdynpro Binary cache" in SAP Online Help.
From the SAP Online Help pdf document, i have found that, the context node data has been converted first in to XML file,after that file had been stored in the web dynpor binary cache...bla....bla.........
Here my qtn is why they had converted context node data into XML file. With out doing that can not we export context node data to excel file..?
Regards
Seshu
Edited by: Sesshanna D on Dec 19, 2007 7:25 AMHi Sesshanna,
it is not neccessary to do that but xml has the advantage, that it can be easily transformed into every output format that might occur in later project stages.
If it's simply about blowing out some Excel, I suggest using an OSS library such as jexcelAPI or Jakarta POI and building the Excel how you need it.

Regarding creation of node element
Hi
i hav a doubt regarding creation of node element. u can create new node element using method create(cn)Element available either directly from wdContext or from wdContext.node(cn) where cn is any context node.
can any one plz explain me what's the difference between two.
does it has any thing to with node being singelton or non-singelton?
also can anyone explain me the difference between add and bind method.
thanks.hi
good
Data Binding Methods
If a property can, or must be bound to the context, the respective bind and bound methods are available.
● The bind methods bind the value of a property to the context element specified by the path.
The name of the method is created according to the following pattern:
BIND_<runtime name of the property>.
Example: table, property: design, method: BIND_DESIGN.
● The bound methods return the path of the context element to which a property is bound and return NULL if no binding exists.
The name of the method is created according to the following pattern:
BOUND_<runtime name of the property>.
Example: table, property: design, method: BOUND_DESIGN.
ADD METHOD->
Two add methods that add an element.
○ If only the element is transferred as parameter, then the element is added at the and of a list
○ If an index is transferred as well, then this element is transferred at the specified index position.
