Dear BaseX,
according to github instructions I’m sending a bug report via email: Using BaseX 9.5.1, cmd-line “basex.bat -i datafile.xml queryfile.xq” leads to no result at all. I’m convinced there should be result equivalent to the one of the online xquery tester (https://www.videlibri.de/cgi-bin/xidelcgi) For a modified query using string comparison based on fn:path(), BaseX gives the expected result. %%% query begin %%% let $rootElement := /child::* for $x in //Section[parent::* != $rootElement] return fn:path($x) %%% query end %%% %%% data begin %%% <root> <Section id="should not be reported 1" /> <Section id="should not be reported 2"> <Section id="should be reported 1"/> <a> <Section id="should be reported 2"/> </a> </Section> <a> <Section id="should be reported 3"/> </a> </root> %%% data end %%% %%% modified query begin %%% let $rootElementPath := fn:path(/child::*) for $x in //Section[fn:path(parent::*) != $rootElementPath] return fn:path($x) %%% query end %%% Kind regards Jan Červák
