stregex - lookaround operators? [message #56376]

Does stregex support the lookahead and lookbehind operators? I'm
guessing it doesn't, which is a real bummer. Specifically I am trying
to use the lookahead operator to extract data from an XML like string:
'[^>]*(?=</rid>)' which should extract all characters before the </
rid> tag up to ">". But I get an error:

STREGEX: Error processing regular expression: [^>]*(?=</rid>)
repetition-operator operand invalid

I think the expression is valid. Has anyone used the lookaround
operators in IDL?
