MathML in HTML

As mentioned in an earlier post, I'm experimenting with Peter Jipsen's script for using MathML in posts served as text/html. The original script assumed a MathML enabled browser, I've just added some conditional code so that if Gecko or MathPlayer are not detected, some CSS, mainly due to George Chavchanidze, is inserted. It doesn't do all of presentation MathML yet but it renders fractions, msqrt and superscripts enough to make the above post more or less legible in Opera. Things need a bit more tuning yet, I seem to have introduced a noticeable delay before the mathematics is rendered (in all browsers), but progress, I think...

Just testing...

I probably won't be posting too much MathML here, but I wanted to check it was possible. Unfortunately I think blogger always serves as text/html, but Peter Jipsen's script seems to work well in this context. Currently it requires a Gecko browser such as Firefox, or IE with MathPlayer installed. Hopefully I can extend the script to allow some basic CSS rendering in other browsers later.

I also needed to check I could write posts in emacs of course!

Finally some examples using the MathML in HTML script. $\frac{1}{2}$

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

[update, continuous Relax NG validation of the mathml in xhtml in atom markup as I type into this emacs buffer. Isn't emacs wonderful. Will post schemas used shortly.]
