[Phpwiki-talk] Defining new tags dynamically

[Bruno B. G. <br...@ls...>]

	Is there some practical way to define new tags and have them
substituted to code by a preprocessor? What I'm looking for is something
pretty similar to what in C would be:

#define <math>    <?plugin TeX2png text="$$
#define </math>   $$" ?>

	So when someone writes:

<math>x^2</math>

it's preprocessed and translated to:

<?plugin TeX2png text="$$y^2+x$$" ?>

before being processed by the wiki. I think it would clean the syntax
and ease some repetitive tasks.
	It seems that there's no support at all for it, and I'm willing
to implement it, but I need a bit of help to find myself around the
code. I suppose this code would go into BlockParser.php, perhaps at
_getBlock?
	Any ideas or suggestions are appreciated.

Never worry about theory as long as the
machinery does what it's supposed to do.
