Thanks, this works for me. At some point we might need to do this more
honestly, ie add a configure probe and do
#ifdef HAVE_XMLXPATHSETCONTEXTNODE
xmlXPathSetContextNode(cur, xtCxt->xpathcxt);
#else
xtCxt->xpathcxt->node = cur;
#endif
but that can probably wait until libxml does something that breaks
the direct-assignment coding. If the latter is the way you were
supposed to do it before, I think they'd be hesitant to break it.
