Thank you Martin. I had not considered pickle, and I've done my
research. However, I'm still having problems:
Your foo class (for pickle and xml dumps) works fine for me.
>>> f=Foo()
>>> f.thanksTo='Martin'
>>> f.howMany=100
>>> pickle.dumps(f)
"(i__main__\nFoo\np0\n(dp1\nS'thanksTo'\np2\nS'Martin'\np3\nsS'howMany'\np4\nI100\nsb."
But for my identifiedPeaks class (for instance), it has trouble. This
class contains a list of "peak" classes IdentifiedPeaks.Peak...
>>> from IdentifiedPeaks import IdentifiedPeaks
>>> identifiedPeaks=IdentifiedPeaks()
>>> identifiedPeaks.read(open('input/analysisReport.txt'))
>>> pickle.dumps(identifiedPeaks)

Help would be hugely appreciated.
