BaseX 7.7 error in working with EQNames
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.
Dimitre,
thanks for the bug fix, for which I’ve created an entry in our bug tracker [1].
Best, Christian
