Re:  Using contains with more than one string - XSLT2.0
Hi Michael --

Pretty sure.  Using equal would constrain it to exact matches, yes?  Which is
not what I want.  For example, I want to use "neg" to find "negatives"
"negative" "neg" "negs" and so on, since the exact phrasing may vary.

Either use matches() as David Sewell suggests, or construct an expression
along the lines

contains(., 'abc') or contains(., 'xyz') or contains(., 'pqr')

But are you sure you actually want contains()? People often misuse it,
thinking it means "Node N contains value V". For that, you want an "equals"
test.
