Hi!
I'm using Xerces and am having trouble with a particular problem.
Problem:
I have a Document object where I need to replace the document element
with a new one. Essentially, I am building a XML document editor, where
I first read in the document, edit the nodes as Java objects and then
export the object hierarchy to XML nodes again.
Solution 1:
Use doc.replaceChild(newRoot,doc.getDocumentElement());
But this didn't work because the implementation tried to insert the new
node before the old one was removed -> structural error. Isn't this a
bug??
Solution 2:
Remove all old children, and insert the new ones:
-------
Element oldNode = doc.getDocumentElement();
NodeList list = oldNode.getChildNodes();
for (int i = 0; i < list.getLength(); i++)
oldNode.removeChild(list.item(i));
list = newRoot.getChildNodes();
for (int i = 0; i < list.getLength(); i++)
oldNode.appendChild(list.item(i));
--------
But this only removes the text nodes of the root document for some
reason. I thought that getChildNodes retrieved all nodes?? Anyway,
calling oldNode.hasChildNodes() after the removal returns true.. bug?
Workaround:
Does anyone know a working solution to this problem? It's a showstopper
for me right now...
Thanks,
Rickard
