Hi Eitan,
works for me. What is your expected output and what do you get instead?
General advise for your query: Using / instead of // would be sufficient in this case and is in general is much more performant.
Cheers,
Dirk

Hi Eitan, perhaps there is a misunderstanding concerning CDATA sections?
In case you are not aware of it:
1) XQuery cannot see CDATA sections - their content is just part of the text content. Regard it as an evelope which does not influence the letter contained. As a consequence, it is principally not possible to *select* any text based on whether or not they are in CDATA sections.
2) XQuery output does not use CDATA sections, unless you supply the serialization parameter "cdata-section-elements", which contains a whitespace-separated list of element names. The contents of these elements will then by serialized as CDATA sections.
Example:
basex -i input.xml -s "cdata-section-elements=package folder" myquery.xq
Kind regards,
Hans-Juergen
