I have a form that the user is allowed to type plain text and/or HTML into. I need to recognize urls within this text that have not already been wrapped in an anchor <A HREF>
tag, and then wrap them so they end up as hyperlinks. If already wrapped, I want to leave them alone.
I have an expression that does this for the whole string:
$myformtext =~ s!(http://[^\s]+)!<a href="$1">$1</a>!gi;
But can I somehow apply this only to the portion of the text that is not within an <A HREF>
tag? Maybe split it or something? I'm not a perl expert...

<li> <nbsp> <ol> <p>
<small> <strike> <strong>

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
