Two things I'd personally suggest.

One, do a non-greedy match with .*? (although I'd wonder if there's no data -- perhaps use .+? instead). Not critical, just precautionary.

And two, verify your match (this could probably be more elegant, but just to illustrate the point):

my $msg;
if (/msg=(.*?) Src/) {
    $msg = $1;
}
#else {
# possible error message here, whatever is appropriate
#}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
