With the following regex I would like to extract the value for "rn", only after the "action=login" has occured. This because the page (text) from which I want to extract this has multiple "rn" occurances.

a little help on this would be very welcome, as this goes well beyond my perl/regex knowledge

source string: 
....
<form method="post" action="login.lp" name="authform" id="authform">
        <input type="hidden" name="rn" value="-1383135969">

my working regex so far:

$message =~ /\"rn\"\s+value\=+"([^"]+)"/ ;
$rn= $1;

my attempt of recognizing the pattern first:

$message =~ /^action.*\"rn\"\s+value\=+"([^"]+)"/
