=head2 STRIP HTML
Because I did wanted to match only the nodelets start here comment and
+ not
these tags before the comment, I just strip the html off usign substr
(last 55 characters).
</td>
<td width="20%" valign=top align=right>
=cut
# L to the V to the A to the L
substr($CRAP,-55) = '';
# and now to massage crap (reverse the effects of code tags
$CRAP =~ s{\n<FONT color="red">\+<\/FONT>}{}g;
# multiline code
$CRAP =~ s{<pre><TT><FONT size="-1">}{\<CODE\>}g;
$CRAP =~ s{</FONT></TT></pre>}{\<\/CODE\>}g;
# single line code
$CRAP =~ s{<TT><FONT size="-1">}{\<CODE\>}g;
$CRAP =~ s{</FONT></TT>}{\<\/CODE\>}g;
$CRAP =~ s{\<\;}{<}g;
$CRAP =~ s{\>\;}{>}g;
$CRAP =~ s{\[\;}{\[}g;
$CRAP =~ s{\]\;}{\]}g;
$CRAP =~ s{\"}{"}g;
$CRAP =~ s{\&}{\&}g;
print $CRAP if(@ARGV);

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
