Dang! I thought for sure this would work... such a good idea. Unfortunately with this syntax the compiler throws an error:
"Call to a possibly undefined method 'child'" Note the first thing I did was make sure I was in fact using an XMLList variable, and that the child method was defined.. Darn... I guess for now its just going to take a custom filtering function. Maybe someday later we can use the predicate filtering syntax with a variable. Thanks guys for trying!
