Like this...
-- code --
my $text = "Hello 1234, come in";
$text =~ /(\d{4,4})/;
$match = $1 if $1;
print $match;
-- end code --
By putting brackets round the section of the regex you want, perl will store
that data in the special $1 variable (it's read only so assign to another
var if you want to make changes. Also the next time you match $1 is
overwritten). You can pull multiple values out of the same regex by putting
multiple () round different sections. The results are stored in $1, $2, $3
etc in the order of the match.

Subject: extracting *just* matched text
hi,
how does one extract *just* the matched text in a regular expression,
e.g.
my $text = "Hello 1234, come in";
if ($text =~ /\d{4,4}/)
{
#grab just the 4 digit number
}
thanks
