the op is having trouble getting a string to render in a HTML browser.

It doesn't _ignore_ that part of the string. The reason why it will not
render in the browser should be obvious to a web developer. The construct
"<gimp>" is a tag, plain and simple.

You mentioned you tried to escape the html metacharacters in the string but
didn't show how you tried to accomplish this. That is where your problem is.
Note:

[EMAIL PROTECTED] trwww]$ perl
use warnings;
use strict;
use CGI;

my($literal) = 'searchtest<gimp><10>';

print( CGI::escapeHTML( $literal ), "\n" );
Ctrl-D
searchtest&lt;gimp&gt;&lt;10&gt;

This will render the string as desired in a browser.
