Converting LF/FF delimited logs to XML w/ Python?

P: n/a
This is a very noob-ish question so I apologize in advance, but I'm
hoping to get some input and advice before I get too over my head.

I'm trying to convert some log files from a formfeed- and
linefeed-delimited form into XML. I'd been thinking of using Python to
do this, but I'll be honest and say that I'm very inexperienced with
Python, so before I dive in I wanted to see whether some more
experienced minds thought I was choosing the right tool.

Basically, what I want to do is convert from instant messaging logs
produced by CenterIM, which look like this (Where "^L" represents ASCII
12, the formfeed character):

^L
IN
MSG
1190126325
1190126325
hi
^L
OUT
MSG
1190126383
1190126383
hello

To an XML-based format* like this:

<chat account="joeblow" service="AIM" version="0.4">
<message sender="janedoe" time="1190126325">hi</message>
<message sender="joeblow" time="1190126383">hello</message>
</chat>

Obviously there's information in the bottom example not present in the
top (account names, protocol), but I'll grab those from the file name or
prompt the user.

Given that I'd be learning as I go along, is Python a good tool for
doing this? (Am I totally insane to be trying this as a beginner?) And
if so, where should I start? I'd like to avoid massive
wheel-reinvention if at all possible.

I'm not afraid to RTFM but there's a lot of information around on Python
and I'm not sure what's most relevant. Suggestions on what to read,
books to buy, etc., are all welcomed.

Thanks in advance,
Kadin.

* For the curious, this is sort of poor attempt at the "Universal Log
Format" as used by Adium on OS X.

I've used lxml and DOM/minidom. Both took my a while to figure out and
I still don't always understand them. Anyway, lxml is similar to the
method Chris mentioned.
