[Greasemonkey] XPath problem

[Gareth Andrew]

Just off the top of my head... 
Have you tried XPathResult.UNORDERED_NODE_ITERATOR_TYPE.  I think if you
want to use snapshots you are meant to use
xpathResult.snapshotItem(index) to access the results.  It might also be
worth looking at the values of xpathResult.resultType and
xpathResult.snapshotLength.
http://www.xulplanet.com/references/objref/XPathResult.html is a handy
resource.

Hope this helps,

Gareth
