So do I, even though I wrote this (and I'm quite ashamed to admit it).
I'm pretty confident this will break as soon as it encounters
something not formatted like the Tomboy notes I have on my computer.
I'm saying this because I'm far from understanding the intricacies of

I'd be in favor of this solution, provided we do not find any blocker.
Xml is a complex beast and I'd sleep better at night knowing someone
knowledgeable about the format handles the decoding for us.

I initially tried to extract the raw content between the note-content
tags with SAX and couldn't find any way to do it. But this could be
handy if we manage to do it, we get the best of both worlds: a tested
library to decode xml and parsing only what we need to show the note

If I remember correctly, the regexp solution is the one used by Tomboy
in the web sync addin.
