    What will happen when a <body> tag is included in comments? Your regex will break. I'm almost sure that the one who gave the instruction to find the <body> of the HTML code with a simple regex did not think about this.

      Interesting observation - do you often see body tags enclosed in comments? You are assuming the poster doesn't want body tags enclosed in comments. ;) In any case, I think this pattern is better (added ^):
      my $body = $the_html_string;
$body =~ s/^.*?(<body.*?>)/$1/sgi;

        One can put anything in comments. Sometimes I have different alternative opening tags and the one I don't need I simply comment out. A naive regex search for the opening <body> tag would perhaps find the wrong (=commented out) tag.

        You will still end up with a trailing </html>-tag and any comments outside of the closing </body> tag.
