Can you elaborate on "not working?" What language is this in, and can you give a few test strings and some sample code that you've tried it in? It seems to work fine if you plug it in here: http://regexpal.com/ – jonvuri Mar 06 '13 at 11:57

Define "negate". Do you mean anything other than exactly `*.INFO`, or anything not *containing* `*.INFO`? – Bohemian Mar 06 '13 at 12:02

I am writing this rule in a lex file. The test file look like: * \n *.ABCD \n *.MNC a=10 \n *.INFO A B C D \n start. Now i just want to ignore the strings which starts from *. except *.INFO. So i need to define a rule which identify all strings starting from *. except *.INFO. @Bohemian So i mean anything starting from *. other than exactly *.INFO . – user2114865 Mar 07 '13 at 04:52

@user2114865 looks like you are right http://www.regular-expressions.info/refflavors.html – VladL Mar 07 '13 at 11:53

Based on your recent comment, this matches anything starting with *. except *.INFO:
\*\.(?!INFO\b)\S+
Note that by adding the \b to INFO this will match strings that start with*.INFO but are followed by other characters, eg *.INFOXYZ

Give more detail about what you're trying to do. For example, maybe you can filter the file list before it goes into your tool – Bohemian Mar 07 '13 at 07:39

i am just trying to match some specific pattern from file and then simply generating the list of matched patterns. – user2114865 Mar 07 '13 at 09:46
