Your problem description is somewhat minimal, but your title suggests that you are looking for the 's' modifier. So make your regex like:

$var =~ m/some text\nand more/s;
[download]

The last 's' makes sure all text is read like one string, even if it contains newlines.

Of course you could have read this in perlop and prelre.

Hope this helps,
