Hi Radim,

Thanks for the observation. Could you possibly provide us a little self-contained example (e.g. with a single document that we can use for creating a database) and drop the lines of code that are not necessary to understand the problem?

Thanks in advance, Christian

Hello,

I have problem with namespace 'www.ni.com/TestStand/ATMLTestResults/3.0'. It works for "return" statement, but when I use a value from this namespace in "where" or "order by" statement, the query returns just an empty string, like no results would have been found, although they exist.

In more detail, I have following query:

declare namespace nTestResultsCollection='urn:IEEE-1636.1:2013:TestResultsCollection'; declare namespace nTestResults='urn:IEEE-1636.1:2013:TestResults'; declare namespace nCommon='urn:IEEE-1671:2010:Common'; declare namespace nNi='www.ni.com/TestStand/ATMLTestResults/3.0';

</Result>

If I remove the where (($TestSystemItem1 = 'dx5484')) statement ($TestSystemItem1 is from nNi namespace), it works fine and TestSystemItem1 values are returned properly in the result in the <TestSystemItem1>{ $TestSystemItem1 }</TestSystemItem1>. However, if I put the $TestSystemItem1 to the where statement (like in the example above), or to the order by statement, it returns empty result.

Is there a way how to fix it? Or is it fixable in the BaseX itself (maybe in the new version)? We cannot change the value of 'www.ni.com/TestStand/ATMLTestResults/3.0' because the xml files are generated by the 3rd party.

Thank you for your help in advance. Best regards,
