Hi all, I'm trying to use WebKit's interface to discover nodes that I
may be interested in exploring or working with. However, the below
code never returns a node list. However, document is valid, and I can
print the contents of the HTML. The only item on the webpage I have
been testing is a submit button. Previous attempts include \\*, and
other queries. Nothing seems to work. I've been debugging and stepping
through webkit all day. The strangest error I have found is (in
XPathResult), while stepping through the iterateNext, somehow the
result type because 111 -- which causes this to exit. I have spent a
ton of time looking for the cause of this, but I seem to be doing
everything properly. If anyone can provide advice on this, it would be
greatly appreciated.
Thanks!
