So let's step back one square: what kinds of things are you trying to match?

Trying to match: client.project.subproject where:

Does that help?

Update:Actually your regex /([^.]+)\.(\S+)/ works well. Thank you.

    OK, to match those possible characters (and only those) try something like 
    m/((?:\w|\\\&|\-)*)\.((?:\w|\\\&|\-)*)/

    the \w takes care of letters, numbers and _. I always escape the - out of habit but is unnecessary. The /i is redundant since the \w is case insensitive.
    Personally I would do a nongreedy match. It will match other characters but it probably won't matter. Something like: 
    m/(.*?)\.(.*)/

    update -- of course a simple split would do the trick. 
    my ($client, $project, $subproject) = split /\./, $x;

      Neil bangs his head vigourously against his desk. Of course! Why the hell didn't I think of that before?

      Thank you all for your input.

    Arturo is right -- I don't see how anything is getting assigned to $project, since the match does not succeed at all for the initial example.

    Trying to match: client.project.subproject where:

    • Client and project are manditory. Subproject is optional but, there could be more than one.
    • Client, project and subproject could contain, letters, numbers, _, -, or \&

    Update:Actually your regex ... works well. Thank you.

    Arturo's regex will include both your project and all sub-projects in $2. If that's okay, fine. If not, do it like this: 

      /([^.]+)\.([^.]+)/
