xF1 Add-on Post Content Find / Replace 1.0.0

This is a very simple add-on I put together in order to allow an administrator to do a regular expression find and replace in the content of all posts.

It was written in order to find all instances of a custom BB code tag for embedding YouTube video in an imported posts, and convert them to XenForo's :

Quick Find:
[video

Regular Expression:
#\[video=youtube;([^\]]+)\]([^\[]+)\[/video\]#siU

Replacement String:

Limitations:

1. The system will not check that your regular expression is valid, or that it matches. It will fall over if your expression does not compile, and it will simply not match anything if the logic is incorrect.
2. There is no batch processing in this add-on, so if you are replacing something that occurs in a lot of posts, this could be very slow and might time-out.

So, given those limitations, I may as well release it seeing as it's written now. It might serve as a useful tutorial in creating an add-on anyway.

Enjoy.
