How to add a custom parsing code ?

[ShayA]

Hello,

I would like to add some rule in the editor that will translate a specific string to an html code (very similar to the BB code principle).

For example, suppose the use add this link to his message www.xxx.com?ht=14234 (it will always be from the same domain)

I would like to take the ht var value and base on that to replace the all link with a valid html code.

What would be the best way to do it so if I will update vBulletin my changes will be still there.

Many thanks,
