I tried something like
"
public static void removeTextNodes(Node node) {
if(node.getType == Node.TextNode)
{
node.getParent().removeChlid(node);
}
else
{
// If there are any children, visit each one
NodeList list = node.getChildNodes();
for (int i=0; i<list.getLength(); i++) {
// Get child node
Node childNode = list.item(i);
// Visit child node
removeTextNodes(childNode);
}
}
}"
Anyway you method looks better I'll give it a try.
Thanks.

What did you try? I did a quick experiment with:
NodeIterator iterator = ((DocumentTraversal)
doc).createNodeIterator(doc, NodeFilter.SHOW_TEXT, null, false);
Node nextNode = iterator.nextNode();
while (nextNode != null) {
// we know it's a text-node
Text textNode = (Text) nextNode;
nextNode = iterator.nextNode();
System.out.println("textNode.getNodeValue() = " +
textNode.getNodeValue());
if ((textNode.getNodeValue() == null) ||
textNode.getNodeValue().matches("^\\s*$")) {
System.out.println("removed");
textNode.getParentNode().removeChild(textNode);
}
}
iterator.detach();
And that seemed to do it. Not sure if this is legal (changing the DOM
during iteration?) and whether this would also filter out empty
attributes, but you could use it as a basis?
It seems to be smarter to do this that your preparser working on the
stream.
Kind regards,
