compilation

Hello, I have the following PHP variable : $string = '<xen:h1>Demo</xen:h1>' ; I would like to compile it using XenForo's core PHP functions, so I get the following result : "<h1>Demo</h1>". It's exactly like XenForo's templates would do, but without using templates ! Any ideas ?

Hi, this is my first post over here. I have an idea for a wiki page and I'm thinking about hosting it on a forum basis. Does anyone know forums based on this kind of concept? Thanks.
