Description:
------------
Parsing named links results in a link which is immediately closed, followed by the name of the link and then the exact same link again. One example taken from your documentation:

[url=http://www.totalgeek.org]totalgeek.org[/url]

will result in

<a href="http://totalgeek.org" onclick="window.open(this.href, '_blank'); return false;"></a>totalgeek.org<a href="http://totalgeek.org" onclick="window.open(this.href, '_blank'); return false;"></a>

I checked this with both, v0.0.4-alpha and the CVS version. Both are showing this behaviour. Unfortunately I do not understand your RegExes well enough to provide a solution for this...

On a sidenote: Parsing will fail at all if the protocol for the link is omitted. For instance [url=totalgeek.org]totalgeek.org[/url] won't parse at all. I'm not quite certain if this qualifies as a bug, but since you allow relative links, I thought you should know.

I jsut checked for PCRE. It's version 6.6.

Update: I've just checked this with an updated build of PHP (v5.2.0) linked with PCRE v6.7. Same problem.

And two new ones: PHP v4.3.10 with PCRE v4.5 on a Debian system and PHP v5.2.1 with PCRE v6.7 on Windows XP SP2a.

Out of curiosity: Which version of PCRE are you using? 7.0? If so, I might give it a try...

Uh, sorry. I've been developing my own BBCode parser in the meantime and lost track of this...

So, this is PHP v5.2.5 w/ PCRE v7.3 on Windows XP: Text_Wiki (v1.2.0) and Text_Wiki_BBCode (v0.0.4-alpha) are working as expected. I can no longer spot this behaviour.
