I'm updating an application at the moment that generates simple HTML
files. However, it's all done using plain strings and brute force.
It's hard to read, and isn't very robust in the face of special
characters and matching start and end tags.

Why not really keep the test code with the main code?

Is there some way to create a wrapper around a 2.4 csv.reader to
give me pseudo line number handling? I've been experimenting with:

If I have the following data file, data.csv:
1 2 3
2 3 4 5
then I can read it in Python 2.4 on linux using:
import csv
f = file('data.csv', 'rb')
reader = csv.reader(f)
for data in reader:
print data

I've taken over someone else's code (yes, honestly!) that has a
complex class hierarchy on top of the main procedural code. This
is unfortunate because it means that isinstance() is everywhere.

This is neat, but not all of the parsers work on a 'line by line' basis,

I was sure that this must be a frequently asked [homework?] question,
but trying to search for 'file open line number' didn't throw up the
sort of answers I was looking for, so here goes...
