It is not. That is the reason for E4X EcmaScript standard, but currently
is only supported by Firefox 1.5, therefore i did not explore this way.

A desperate XSLT hacker? ;-)

Thanks by the link. It is true that you can write a XSLT transforming
textual content as \alpha to XML stuff, for instance to <mi>&alpha;</mi>,
and you can write 20 XSLT matching rules. The XSLT is very verbose but
works. However, as correctly pointed Carlisle already matching braces is a
interesting issue in XSLT.

I have taken a look to documentation of the latex2xml project and whereas
you can see TeX commands as \"o, \scriptsize, \Omega, and \$, ^, \}, or \(
between others in the LaTeXCommands.xml file, you do not see simple { or }
or \frac{}{}. Probably, the preparser transforms matching braces and other
difficult stuff and after the remaining text is done via XSLT. I do not
know.
