[SimpleParse] How to process the tree?

[Martin d'A. <Mar...@s2...>]

Hi,

I have got the following program which works very well, but does not do 
anything useful after it produces a correct taglist:

import os
from sys import stdin, stdout, stderr
from simpleparse import generator
from simpleparse.common import comments, numbers
from mx.TextTools import TextTools
import pprint

input = stdin.read()
decl = open('pif_works.def').read()
parser = generator.buildParser(decl).parserbyname('source_text')
taglist = TextTools.tag(input, parser)
pprint.pprint(taglist)

Now I want to create 4 different output formats (HTML and LaTeX are two of 
them).

I tried to subclass the DispatchProcessor, and added a function for each
production I had (with a simple print statement in each one). I
instantiated MyProcessor class once. Now I don't now what to do. What
function should I call to get the ball rolling?

I have read the examples in simpleparse/common as recommended, but I just
don't see how tree processing gets started.

Thanks,
Martin
