Hi Dimitre, the bug you encountered has now been fixed [1]; feel free to check out the latest stable snapshot [2] (7.7.1 will be released soon). Best, Christian [1] https://github.com/BaseXdb/basex/issues/744 [2] files.basex.org/releases/latest ___________________________ 2013/8/11 Dimitre Novatchev <dnovatchev@gmail.com>:

Hi,

Given this XML document (in file example.xml):

<p xmlns="http://example.com/one" xml:lang="de" author="Friedrich von Schiller"> Freude, schöner Götterfunken,<br/> Tochter aus Elysium,<br/> Wir betreten feuertrunken,<br/> Himmlische, dein Heiligtum.</p>

This XQuery expression (in file TesQNametExpression.xquery, in the same directory):

let $doc := doc('example.xml') return

string-length($doc/Q{http://example.com/one}p[1]/@Q{http://www.w3.org/XML/1998/namespace}lang)

produces:

0

However the correct result (which I get with Saxon 9.5.01) is:

1

Here is the "Query Info" from the BaseX UI:

Compiling: - pre-evaluating fn:doc("example.xml") - binding static variable $doc - removing unknown element/attribute Q{http://example.com/one}p - pre-evaluating fn:string-length(()) - removing variable $doc - simplifying flwor expression Query: let $doc := doc('example.xml') return string-length($doc/Q{http://example.com/one}p[1]/@Q{http://www.w3.org/XML/1998/namespace}lang) Optimized Query: 0

Hope that this information would be useful for identifying and fixing the issue.
