Re: Re: Thought i knew this but i guess not

I guess, it's not that hard.  You can have commas and spaces in any
combination.
How about this, assuming you're looking for $wantFilter:

contains( concat( normalize-space( translate( @filter, ",", " " ) ), "
" ), concat( $wantFilter, " " ) )

Russ, here are the steps:
- First translate all commas to spaces
- Then normalize-space -- look up that function if you don't know what
it does.  If all you have are spaces (and no tabs, for example) then
you can skip this.
- Add a space to the end, just for good measure
- Also add a space to the end of the thing you're looking for.  This
prevents "filter1" from matching "filter11".
- Then see if there's a match.
