exclude

Hi,

I have got some strings to be matched via RegEx. We have a java application which reads the regex from a config file and takes two groups of strings, number of which are specified in the same config.

E.g.

CustomAction.523274ca945f.dialogLabel=Executing Custom Code...

will be matched with

(?m)^(?!#)\s*(\S*)\s*=\s*(\S*.*)

What I need is to pick the first group "CustomAction.523274ca945f.dialogLabel" and exclude the random string in the middle so I end up with something like "CustomAction.dialogLabel" or "CustomAction..dialogLabel" well any other combination but the random string.

Thanks
