The only caveat is that your data set looks like an HTML(SGML) file.
However, there are parsers for nearly any language (well, Java, C++,
C, PERL, and Python come to mind), which are nicely licensed.
Writing out the XML DTD for statistical datasets (and for
communicating the need for procedures of a certain type on those
datasets) has been simmering in the back of my mind for a while, now.
I'd be interested in hearing from anyone else who has been playing
with XML for passing data (my application is for inter-stat package
communication, but might not be bad for with-in package communication,
but it needs a bit more exploration).
It would also lead to WWW-friendly processing :-).
