Re: [Webware-discuss] regexp help

[Chuck E. <ec...@mi...>]

I haven't studied your exact example in depth, but in general, I'm pretty 
confident that if you have a language with multiple, nested blocks, you 
really need a parser, probably a recursive descent parser. Usually these 
sit on top of a lexer that is based on regular expressions.

You are no longer in the realm of simple regexes. Mwahahahaha!

In fact, if I thought that my proposed template language could have been 
done with regexes, I probably would have done it a long time ago.


PSP should be no different so you might look at the source there for hints.
