First, I'm very surprised that you're seeing R elements that don't have a
child T. Can you confirm that these are actually what you're getting back
from your GSA or Mini?
Second, you can't test for the existence of array elements with IsDefined.
But you can store the array element within a variable, then test for the
existence of members of that variable:
<cfloop ...>
<cfset thisR = XMLContent.GSP.RES.R[idx]>
<cfif IsDefined("thisR.T")>
</cfloop>
Don't forget, you can also use XPath expressions from within CF. You might
find that an easy alternative to accessing elements directly, although to be
honest I haven't tried that myself from within CF while using Google search
result XML.
