I made an example fasta file containing just this one sequence twice:

I then edited the filenames in your example, and ran the code.  It 
worked for me using a fresh install of BioPython 1.41 on Linux with 
Python 2.4.2

So the good news is your code seems fine.

Maybe there is something "funny" with your fasta file?  Accented 
characters for example - which would then be in the output XML file?

Could you send me the fasta file and the XML file (in full, as 
attachments), off the mailing list to avoid clogging up everyone's inboxes.

Thanks
