in reply to Multiline regex

If you want to do your matching about the whole string (containing multiple lines), then you want /s (also let the dot meta character match line breaks).

my ($body) = $line =~ /^body: \n (.*) \n attachment/xsi;

Or you are matching line by line, then you should have a look at the flip-flop operator in perlop.

# this is from perlop while (<>) { $in_header = 1 .. /^$/; $in_body = /^$/ .. eof; if ($in_header) { # ... } else { # in body # ... } }

    Also see Flipin good, or a total flop? for a good discussion of the flip-flop operator by Grandfather.
