in reply to Regular expressions are:
Both a blessing and a curse --
I'm used to using regex in Perl, or other apps using PCRE, but I have to do work in IDL ... and they have what they claim to be regex support, but it lacks:
- Non-greedy quantifiers
- lookahead / lookbehind assertions
- all of the zero-width assertions other than $ and ^
- \w, \d, \s, etc.
- non-capturing parenthesis
So ... anyway, not all regex are created equal -- Perl regex good ... IDL regex is a steaming pile.
