Is that because you don't understand XML or because the 
output is not what you expect? How is the data being generated? 
Are you parsing an existing XML source or creating the XML 
from scratch? I'm not sure I understand your problem.

' <order>' + instance.order + ' </order>\n' + \
'</record>\n')

You can simplify this quite a lot. You almost certaionly don;t need 
the outer str() and you probably don;t need the \ characters either.

Also it might be easier to use a triple quoted string and format 
characters to insert the dasta values.

Why do you need to parse it if you are creating it?
Or is this after you read it back later? I don't understand the 
sequence of processing here.

Did you try to use the standard library tools that come with Python, 
like elementTree or even sax?

I think we need a few more pointers to the root cause here.
