Problem with recursive xpath 2006-09-26 - By keshlam@(protected)
Sanity-check: Are you altering your DOM model between the two queries?
If so, that's a problem. Our standard DOM adapter is very much a
static/cached adapter; it will *not* tolerate having the document altered
after it has been loaded, and the only thing you can do to overcome that is
to flush the cache by obtaining a new XPath evaluator (effectively
discarding the cached adapter layer) and running the new query against
that.
We have experimented with alternate solutions -- you might want to look at
the DOM2DTM2 prototype, which may still be checked in although it was never
finished, and solving the encapsulation issues more elegantly was part of
the goal of the XDM proposal.
