Thanks for the pointer Andreas. So I guess we cannot use the iterator for
this purpose anymore? I tried out the following bit of code and it seems to
work:
OMNode node =
envelope.getBody().cloneOMElement().getFirstOMChild();
while (node != null) {
OMNode nextNode = node.getNextOMSibling();
newEnvelope.getBody().addChild(node);
node = nextNode;
}
Is this the proper way to solve this problem?
Thanks,
Hiranya
