Xpath to retrieve by Mx ID (GUID)

How can I retrive via Xpath based on the GUID of an object? The documentation states that I can use a 'id' function in my Xpath, see: https://world.mendix.com/display/refguide3/XPath+id However, this doesn't work for me? I'm trying to delete in batch a lot of records of Entity B, that have a relationship with Entity A. Using the executeMicroflowInBatch (CommunityCommons), I want to supply the Xpath (in textstring) from Entity B to Entity A, using the GUID of Entity A. The executed microflow just takes an argument of Entity B and deletes it, nothing special there. Does somebody have an example how to achieve this?

Use the getGUID java action from the CommunityCommons module to get the guid from entity A. The xpath should look like [module.EntityB_EntityA/module.EntityA/id='Your GUID>'] it could be that GUID is without quotes.
