[Exist-development] Xpath error/problem in trunk!

[Andrzej J. T. <an...@ch...>]

Wolfgang:

I've been trying to get my code running under the latest version of trunk (2.1)....but have run into
a weird xpath error.

I've attached both a text.xql file and test.xml file.  Put them in /db and then execute the test.xql.

It dies with the following exception:

	cannot convert xs:boolean('false') to a node set

Now if you look at the rather complex xpath statement, if you remove both the exists() and
normalize-space() comparisons at the end, it works.  Also works if you remove the "and @extension =
$id" clause....or if you remove the "@root = "2.16.840.1.113883.4.98" and" clause.

Very strange behaviour.  This is valid xpath...and worked fine in the older 1.5 version I used in
the past.  Almost seems like there is something going on with the parser or the optimizer that is
causing this weird error.

I'm not conversant with the query/xpath engine, so was hoping you could take a look.  Hopefully this
test case will let you replicate the issue.

Thanks!
