I'm close my problem is the spaces in the after the line breaks. I really need to eval it as a single uuid.. I am working on a calendar migration and I'm trying to find old UUID's and replace them. I attached the entire file just incase you want to see what I am working with.

(?s)urn:uuid:.{8}-.{4}-.{4}-.{4}-.{12}

I think I found 1 option...a bit ugly but hey it seems to work

urn:uuid:(?s).\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*

this seems to work better.

(?s):u\s*r\s*n\s*:\s*u\s*u\s*i\s*d\s*:.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*-.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*.\s*

This would be a bit neater:
urn:uuid:(\S\s*){8}-(\S\s*){4}-(\S\s*){4}-(\S\s*){4}-(\S\s*){12}

Can you strip out the spaces before applying the regex? That would be simpler.

I tried to find and replace spaces but it wont import in to zimbra after words and I can't seem to figure out how to add them back in.

Combining your latest pattern, and mine, I get this, which seems to work ok:
u\s*r\s*n\s*:\s*u\s*u\s*i\s*d\s*:(\S\s*){8}-(\S\s*){4}-(\S\s*){4}-(\S\s*){4}-(\S\s*){12}

Split the tasks into steps:
$blob=<FILE>;
$blob =~ s/\n  //g;
@datasets=split("\n",$blob);

... then you can tackle each dataset separately and you don't end up with a regex which is hell to maintain.
