Structuring the code of a wiki parsing engine

[Michiel Sikma]

Hello everybody. I'm kind of new to Python. I'm working on a simple  
text parser that will allow me to transform a certain syntax into a  
certain output. I find wikis interesting, so wiki to HTML parsing is  
one of the things that I want to accomplish (I'm not actually writing  
a whole wiki, that's complex, but I'm only trying to get basic text  
conversion going on).

Presently, I'm thinking of putting the (simple, regexp-driven)  
filters in a module called "parsers", and then make a "handlers"  
module that allows for the actual transformation. So, for example,  
one parser would be a separate class (WikiParser) which would have an  
attribute called "emph" (emphasis) which is a string '\*\*(.+?)\*\*'.  
Then a handler class (HTMLHandler) would have an attribute called  
"emph" which is a string '<em>\\1</em>'. Then the regular expressions  
would be generated via a chosen parser/handler combination. This to  
make it easy to change things around later.

My question to you: is this the right way to go about it? My parser  
doesn't really need to do all that much, but I would like for it to  
be easily changeable by editing a single file.

Thanks for any help!

Greets,
