Thank you for your help! By using directly children() I got the result I wanted. I had obviously misunderstood some JQuery concepts.
However, another problem raised that is related to this one. In my XML there is a dot (.) in tag name like "<P108B.was_produced_by>". If I use find() I could write something like this: $(xml).find("P98B\\.was_born,P100B\\.died_in,P108B\ \.was_produced_by"); And it worked but this is not working: $(xml).children("P10B\\.contains,P89B\\.contains"); Any ideas about that?
