Re: [xsl] Text markup for web forums, eg. [b]bold text[/b]

["M. David Peterson" <m.david@xxxxxxxxxx>]

Nice catch!  I put this together on the fly when I was in the middle of a 
fairly massive project and obviously didnt think it all the way through.

Let me think through it a bit and Ill send you and update that adds 
recursion to the mix.

Thanks!
