Hi Mark,
No, you don't need to clone anything. If you're trying to turn the entire
result tree fragment into a node-set, you can take a look at what's going
on in the node-set extension function. The source file is
xml-xalan/c/src/xalanc/XalanExtensions/FunctionNodeSet.cpp.
However, if I understand you code correctly, the following is the
equivalent of what you were doing before:
theNodeList->addNode(&(*it).second->rtree());
The node set doesn't own any of the nodes and won't clean them up when it's
destroyed.
Thanks!
Dave

I'm just not sure how I add this to a nodeset. Do I have to clone it?
theNodeList->addNode((*it).second->rtree().cloneNode( false ));
Should the deep flag be set? Does the nodelist then own (and therefore
ultimately cleanup) the cloned tree?
Thanks,
Mark
