Hi all,
I'm trying to use a Java written search code to traverse a DOM
hierarchy.
I'm mainy using code that I obtained from the Sun website. Basically,
in
main(), I have
Element rootElement = XML_document.getDocumentElement();
found_element = findElementNode("ATO_RawXML",
XML_document.getDocumentElement() );
where XML_document is of type Document.
The findElementNode function looks like this:
public static Node findElementNode(String name, Node node)
{
Node matchingNode = null;
//Check to see if root is the desired element. If so return root.
String nodeName = node.getNodeName();
if((nodeName != null) & (nodeName.equals(name)))
return node;
//Check to see if root has any children if not return null
if(!(node.hasChildNodes()))
return null;
//Root has children, so continue searching for them
NodeList childNodes = node.getChildNodes();
int noChildren = childNodes.getLength();
for(int i = 0; i < noChildren; i++){
if(matchingNode == null){
Node child = childNodes.item(i);
matchingNode = findElementNode(name,child);
} else break;
}
return matchingNode;
}
and my XML_document looks like:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<WfMessage>
<WfMessageHeader>
<ResponseRequired>Yes</ResponseRequired>
<UserContext>This data is sent back in response</UserContext>
</WfMessageHeader>
<ProcessTemplateExecute>
<ProcTemplateName>Generate And Disseminate FLY_</ProcTemplateName>
<ProcInstName>FLYPRO_Gen#1</ProcInstName>
<KeepName>true</KeepName>
<ProcInstInputData>
<_ACTIVITY_INFO>
<Priority>1</Priority>
</_ACTIVITY_INFO>
<ATO_ATO>
<ATO_FileLoadedIntoSystem>No</ATO_FileLoadedIntoSystem>
<ATO_RawXML>XML DATA HERE</ATO_RawXML>
</ATO_ATO>
</ProcInstInputData>
</ProcessTemplateExecute>
</WfMessage>
Using IBM WSAD, I put break points in during the for...next loop in
findElementNode, but it skips over the Node with the <ATO_RawXML>
tags.
In main(), found_element is null. What is wrong?
TIA,

Is there any reason you can't use the
getElementsByTagName
method of the document node or any element node to solve that?

The only reason I didn't use that is because I simply couldn't get it to
work
- maybe I got the syntax wrong (I was using the Sun website as a
reference).
