Hi,
Given this type of html (stored in a variable), how can I extract the string after the last <pre> tag: 
$VAR1 = '<html><title>GAL7</title>
<body bgcolor=white>
<h2 align=center>GAL7</h2><hr>
<form method="post" action="/cgi-bin/SCPD/getgene2?GAL7" enctype="appl
+ication/x-www-form-urlencoded">
<input type="submit" name="action" value="Get mapped sites" /><input t
+ype="submit" name="action" value="Get putative sites" /><input type="
+submit" name="action" value="Get interg
enic region" /><br /><input type="submit" name="action" value="Retriev
+e sequence" />Start<-ATG <input type="text" name="start" value="-450"
+ size="5" maxlength="5" />ATG->End <inp
ut type="text" name="end" value="50" size="5" maxlength="5" /><div></d
+iv></form><hr>
<pre>
>YBR018C  GAL7  275433  275933

such that it returns simply: 
my $new_output = '
>YBR018C  GAL7  275433  275933        #this fasta marker line is to be
+ kept

I couldn't figure out how to create mechanism that can distinguished between html tag and 'fasta' tag marked by ">".
