Splitting a DOM

[Brice Vissi?re]

Hello,

I would like to handle an XML file structured as following
<ROOT>
<STEP>
...
</STEP>
<STEP>
...
</STEP>
...
</ROOT>

>From this file, I want to build an XML file for each STEP block.

Currently I'm doing something like:

from xml.dom.ext.reader import Sax2
from xml.dom.ext import PrettyPrint

reader = Sax2.Reader()
my_dom = reader.fromUri('steps.xml')
steps = my_dom.getElementsByTagName('STEP')

i=0
for step in steps:
	tmp = file('step%s.xml' % i,'w')
	tmp.write('<?xml version="1.0" encoding="ISO-8859-1" ?>\n')
	PrettyPrint(step , tmp , encoding='ISO-8859-1')
	tmp.close()
	i+=1

But I'm pretty sure that there's a better way to split the DOM ?

Thanks for any suggestion provided.
