My pattern matching was failing when I had these definitions, which I happen to prefer: const string number = "[0-9]+"; const string name = "[A-z][A-z0-9]*"; ("name" is supposed to match a typical variable name) The program is working fine now, after I am using these ones: const string number = "\\d+"; const string name = "[A-z]\\w*"; The only difference that I aware of, is that the second form accepts underscores as part of variable names. TIA, -RFH

Could you please read documentation before posting question? http://www.boost.org/doc/libs/1_45_0/libs/regex/doc/html/boost_regex/syntax/... "w - Any word character (alphanumeric characters plus the underscore)"

I don't knot about you, but I definitely prefer a human response. If we all read and studied the documentation, you would not have the chance to show your expertise. Check how Microsoft, Sun and others award points (even military-type stars) to folks who provide answers different from a simple "RTFM". Thanks for the URL, no thanks for the rest. :-) -Ramon F.

Ramon, I think, that people should try to find answers independently. Your question about regular expression in general, not in specific of boost.regex library - at first. At second, you ask about base element of regex - clearly, that you no hard to read something more about regex before using it. I spent 15 seconds to find this link. It's not so hard. Seriously...

Correct there should be no difference - do you have a test case? Thanks, John.
