can you point me at any call in libxml2 which will evaluate an xpath expression in the context of a nodeset instead of a document? Quite apart from anything else, xpath requires there to be a (single) context node (see http://www.w3.org/TR/xpath20/#context ). For a doc, we set that node to the document node, but what would it be for a node-set or a fragment? If we can't get over that hurdle we're screwed in pursuing your line of thought.
Which may hint at the fact that running xpath on content fragments is ill-defined to begin with?!?
