Subject: Aw: Re: [docbook] LaTeX math inside docbook, on-the-fly MathML conversion?

I read about <mathphrase>. However, this element is only for a linear sequence of symbols. Not for sums, integrals, matrices or multiline equations.

There is no <latexmath> element in DocBook. However, you can have the same
functionality with equation (for block formulas) or inlineequation (inside a
paragraph). For example, an inline equation of Einsteins famous formula could
look like:

<mathphrase role="latex">E = mc^2</mathphrase>

Sure. In theorey, it needs a three step process: extract all LaTeX formulas,
convert it to MathML (or maybe graphics?), and reinsert it -- or include a

How many formulas do you have? Do they change frequently? Well, maybe you
don't need such a sophisticated convertion. Perhaps you could reference your
MathML formulas with xi:include and do the convertion outside your workflow.

Get some ideas by reading Bob's chapter about Math in DocBook at

Hope this helps. :)
