Assertions with Multiple Nodes in an XML response

Hi,

I'm new to the soapUI game and have been tasked with building assertions for XML Responses.

Forgive me if I get the terminology wrong as I'm not a technical guy.

my objective here is to find an existance of a tag within a tag.

<Team> <TeamID>0</TeamID> <Member> <MemberID>0</MemberID> </Member> <Member> <MemberID>1</MemberID> </Team> <Team> <TeamID>1</TeamID> <Member> <MemberID>0</MemberID> </Member> <Member> <MemberID>1</MemberID> </Member> </Team>

Take this Scenario,

I'd like to add an assertion in soapUI that acknowledges an Existance of MemberID ONLY under TeamID 1. A seperate assertion for MemberID under TeamID 2 as well.

Thanks,
David
