Replaceing text in active forums posts

I want to let people post youtuvbe embedded videos in forum posts (Active Forums 3.6). To do this I decided that I could invent a tag that they could use. So I decided to use the following syntax:

[youtube⒯igHV0CwJk[/youtube]

The part in between the start and end tags is the id from youtube.

I have a javascript function that I feed the id to to display it in the post. I think if I try to post it here it will get changed but here goes a try:

<script language="Javascript">embedyoutube("91igHV0CwJk");</script>

My thought was to change replace [youtube] with the javascript tag up to the first quote of the embedyoutube() function, and also replace the [/youtube] tag with the text from the closing quote to the closing script tag.

However, this caused my site to go BOOM. With a very cryptic error about an XML parsing problem.

Here is the resulting rule as created in the config:

     
        youtube-start[youtube]embedyoutube(]]>
     
     
        youtube-end[/youtube]
     

(I hope the tags display properly)

Anyway, is there a bug that causes this, or is there a better way for me to handle the scenario I described?

The tags in the above post are being stripped.. let me summarize:

I want to take a tag like:

[mytag]  some text [/mytag]

and replace the tag protions with some javascipt that would result in "some text" being passed as a parameter. for example:

<script language="Javascript"> myfunction("some text") </script>

thanks

This could probably be done, but you would need to use a different delimiter on your tokens.  ActiveForums encodes those square brackets on posts because that is what they use for token delimiters.

How about this:

The tag they post can look like this :  {youtube=igHV0CwJk}

Then the replacement rule can be:

SearchFor:  {youtube=(.*?)}

ReplaceWith:  <scriptlanguage="Javascript">embedyoutube("$1");</script>

Ooops.

Ok, we can do even better than searching inside the page body tags and only target the post body.

Try this:

SearchFor:  (afpostbody.*?){youtube=(.*?)}

ReplaceWith:  $1<scriptlanguage="Javascript">embedyoutube("$2");</script>
