Hi everybody!
I'm developer of ReText editor and we want all math to be wrapped in
<div class="math"> and all inline math — in <span class="math"> tags,
so that it had correct (and consistent) styling.
Is it possible to tell MathJax to parse *only* content withing
<div/span class="math"> blocks and not touch everything else?
Cheers,

Hi Dmitry,
Here are links to the doc, with several options to control what is or is
not parsed:
See "elements" http://www.mathjax.org/docs/2.0/options/hub.html
See "skipTags", "ignoreClass", "processClass":
http://www.mathjax.org/docs/2.0/options/tex2jax.html
Hope that helps,

Fred has already pointed you to the documentation on this.
There are two approaches that would probably work for you. The first
is to use MathJax's ignoreClass and processClass values to control the
tex2jax processing (assuming your input is TeX). Set processClass to
include the "math" class, and add class="tex2jax_ignore" to the BODY
element in your document (or put a <div class="tex2jax_ignore"> around
the contents of the page). This will cause tex2jax to only look for
math in the containers that have class="math".
Alternatively, if you are able to recognize the mathematics yourself
already, you could decide not to use tex2jax at all, and mark the
mathematics directly using the <script> tags that MathJax uses for
storing the math on the page. Use <script type="math/tex">...</
script> for in-line math and <script type="math/tex;
mode=display">...</script> for display math. You can put these inside
your class="math" spans and divs if you want. You could also include
<span class="MathJax_Preview">...</span> just before the <script
type="math/tex"> script (with no intervening tags, text, or
whitespace) to include a preview for before MathJax processes the page
(MathJax will remove it as it goes). That could be just the original
TeX code, or something else that marks where your mathematics will
appear.
See
http://www.mathjax.org/docs/2.0/model.html
and in particular
http://www.mathjax.org/docs/2.0/model.html#how-mathematics-is-stored-in-the-page
for details.

Thank you all, ReText is now using <body class="tex2jax_ignore>.
By the way, if someone also wants to use MathJax within Markdown, the
code is available here:

Hi Davide, you pointed out that if we can use the script tags ourselves and not
use the preprocessor. I'm currently including mathjax as follows:
http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full
so that I can use all the macros included with AMS. The question is, how do I disable
tex2jax? My current solution is to configure it as follows:
tex2jax: {
inlineMath: []
displayMath: []
processEscapes: false,
processEnvironments: false,
balanceBraces: false,
skipTags: ["body"],
},
Is there something I just cannot see from the documentation?

Provide your own set of extensions, i.e.:
extensions: ["MathMenu.js", "MathZoom.js"],

The combined configuration files that include the TeX input processor also include the tex2jax preprocessor, and so it will get installed as a preprocessor automatically when you load that file. In order to really disable it, you would have to remove it from the preprocessor list. In fact, in your case, you will get both the tex2jax and mml2jax preprocessors, since this configuration file processes both MathML and TeX. So you might want to clear the entire preprocessor list.
To do that, you can use
<script type="text/x-mathjax-config">
while (MathJax.Hub.preProcessors.hooks.length) {
MathJax.Hub.preProcessors.Remove(MathJax.Hub.preProcessors.hooks[0]);
}
</script>
This clears all the preprocessors. So you don't need to include configuration for tex2jax in that case.
As for why your configuration didn't prevent the preprocessor, I think you also need to set
processRefs: false
in order to disable all its features.
