Re: [xml] Xpath question

Thanks Daniel. I did some tests for xmlSaveTree, it basically prints out
the selected nodes and their children.

Is there any way to print out the selected nodes and their parents (till
root)? I can certainly do the traversal via node->parent. Just in case
you already have some API available (which will trim the non-selected
nodes from the original doc and do xmlDocDump(stdout, doc)).

I plan to use xpath in libxml2 to get a subset of a xmldoc, 
I know it 
can be done by calling xmlXPathEvalExpression(), the result is a 
xmlXPathObjectPtr which has a "nodesetval" member pointing 
to selected 
nodes (of type xmlNodeSetPtr).

My question is, after getting the selected nodes, is there 
any API I 
can call to dump the selected nodes in xml tree format? There is a 
convenient API xmlDocDump(stdout, doc) to dump the whole doc in xml 
tree format, I'm looking for something like xmlDocDumpSubset(doc,
selected-nodes) to dump only the selected nodes in the doc.
