In terms of speed, the performance is very good. A 500kB file with over 
2000 elements is done in less than a second, 3 times faster then XMLTREE 
and much, much faster than XML4MAT.

It does not complain about parsing the non-xml example 1) from 
http://www.cae.wisc.edu/pipermail/octave-maintainers/2006-May/000168.html.
The items 2)-4)  are handled correctly.

Considering the size of the code, there will be hardly a better method 
for reading XML data. Therefore, I think it would be worth to convert it 
to an oct-file.
