Bug Description

The following query returns an empty result if the context-item is set to the attached document. However, the result shouldn't be empty.

declare default element namespace "http://www.w3.org/1999/xhtml";
fn:data (//td [not(@class) and parent::tr[@class]]/a/text())

The result is correct, if the nested @class predicate is removed from the path expression.

The file doc.xml was added: document used as context-item in the query above

Matthias, the query works for me. Can you please double check again?

Markos, I double checked again. In Revision 6506 I still get the empty result. I also double checked with Saxon which gives me my expected result of 260 text nodes. I executed the query as follows (note that doc.xml contains the file that is attached to this bug report):

tmp.xq
declare default element namespace "http://www.w3.org/1999/xhtml";
fn:data (doc("doc.xml")//td [not(@class) and parent::tr[@class]]/a/text())

command
bin/zorba -q tmp.xq -f

Thanks Markos. I verified again (on Linux) and it's indeed a problem only existing on Macs. The problem is because of a bug in libxml 2.2 shipped with Mac OS X. I installed a newer version and it works.
