Sorry if I didn't make this clear from the start. There were two
sets of code. The code you mentioned above I got off python
cookbook. I have just tried this code, and hot this result:

<?xml version="1.0" encoding="iso-8859-1"?>
<foo>
&lt;some text&gt;
</foo>

So the CDATA is escaped! (Though it would be nice to have the
characters unescaped but enclosed in CDATA tags; that way it is
easier to go back and change things on your xml doc before final
output.)

The other set of code apparently uses a different library. I had
been using this code for my parsing, and saw that it wasn't
escaping the CDATA. This code must somehow be broken.

I am a big unfamiliar with the "good" code. I suppose it follows
all of the SAX protocols. However, I notice that it is very, very
slow. It took around 15 seconds just to parse the above data!

Any thoughts as to why the "bad" code is bad would help me. 

Thanks

Paul
