With the clarification in "Re 3", this should give you an approach:

#!/usr/bin/perl
use strict;
use warnings;
# 812662

my @data = ('<td class="c"><input type="hidden" name="recid5" value="1
+0293424">2009/08</td>',
            '<td class="c">foobar - Item &quot;123&quot;: <b>8</b></td
+>'
           );

for my $data(@data) {
    if ($data =~ /"hidden"/ && $data =~ /value="([^"]+)/ ) {
        print "Hidden value: $1 \n";
    }else{
        print "Nothing hidden in \$data: $data\n";
    }
}

Output: 

Hidden value: 10293424
Nothing hidden in $data: <td class="c">foobar - Item &quot;123&quot;: 
+<b>8</b></td>

Update: else {...} added for clarity and output updated

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
