Assuming that you mean that $listfor is the name of an child element of
Member_id, you can use

test='not(.//InqInfo/Member_id/*[name()=$listfor])'

or

test='count(.//InqInfo/Member_id/*[name()=$listfor])=0'

Other variations are possible, depending on exactly what you want to test
for.

You may also want to replace ".//" with some other construction if you need
to get more performance, since ".//" is likely to be slow.  That would only
matter if you have very large files or you need especially fast response
time.

Cheers,
