Re: Escaping parenthesis in regular expressions....

You were close, you need two backslashes.  IE, '401\\(k\\)'  The reasoning
for this is that the first slash is taken off by the preprocessor, and then
it goes through another processor for the regular expression
matching.  BTW: If you ever want to doa  search for a slash itself, you
need 4 slashes, ie: 'This \\\\ way'
