importNode() Problem
I'm trying to utilize importNode() as defined below. I'm using xerces
v1.0.3 and the it appears the importNode is not working.
What am I doing wrong?
==================
String sXML1 = "<?xml version=\"1.0\" ?>" +
"<TEST><ResponseType>XML</ResponseType>" +
"<StyleSheet>login.xsl</StyleSheet>" +
"</TEST>";
try
{
Document doc1 = XMLHelper.getDocument(sXML1);
Element eRoot = doc1.getDocumentElement();
NodeList nlTmp = eRoot.getElementsByTagName("ResponseType");
Node node = nlTmp.item(0);
Document doc2 = XMLHelper.getDocument();
Element eNewRoot = doc2.createElement("TEST");
doc2.appendChild(eNewRoot);
doc2.importNode(node, true);
String sDoc2 = XMLHelper.makeStringFromDOM(doc2);
System.out.println("sDoc=\n" + sDoc2);
}
==================
Thanks
Tom

It's working for me, and I'm using xerces 1.0.3.
The problem is this: importNode *returns* a new Node object whose owning
document is the target doc object. You then have to add that returned node
to your target doc at the correct location. This should work:
Node importedNode = doc2.importNode(node, true);
eNewRoot.appendChild(importedNode);
Take care,

It may not be working as it's suppose to but it returns a Node that is now
owned by the target doc and that's good enough for now.
I'll keep my I out for the new release.
Thanks
Tom

Well, I have resolved my problem.
Whether it is suppose to work like this I'm no longer sure. After reading
the DOM spec again for importNode(), it doesn't say that it will actually
update the target DOM via the import process. My understanding is that it
simply returns the node which is now owned by the target DOM. This may be a
side-effect but it's enough to allow me to place this node in the target DOM
as opposed to letting the import just append it. It actually saves me from
having to build a new DOM, now I can simply call replaceNode() instead.
If I'm assuming in error or have made a big mistake, please let me know.
Thanks again for everyone's help.

Thank-you so much for responding so quickly. I tried adding cloneNode() but
unfortunately it didn't correct the problem.
I'm at a loss and I really don't want to code another solution since you've
already done it.
Any other ideas would be most appreciated.
Thanks
Tom

The node passed to importnode cannot have a parent. In your example, node
is a member of document sXML1.
Just missing the call to cloneNode().
Node newNode = node.cloneNode (true);
doc2.importNode(newNode, true);
