Thanks for the answer.

I tested it with your suggestion, but my problem is that the path
"companyIds/collection-element" does not exist. there is only the path
"companyIds", and "collection-element" is missed. the next problem,
"collection-element" is not a property like you thought, it´s a

So the query you showed me doesn`t go at all.

Is there another possibility to solve my problem? i also tested the
following query:

[(menuIds/collection-element/@menuid='1485') and
-> result the same like [(menuIds/collection-element/@menuid='1485')]

[(menuIds/collection-element/@menuid='1485') and
-> result the same like [(menuIds/collection-element/@menuid='1485')]

[(menuIds/collection-element/@menuid='1485') and
-> result 0 rows
