The primitive \middle of eTeX seems to be unsupported for MathML
output.
Files below are enclosed between lines starting with '------'.
Minimal input file:
--------- test .tex ----------------
\documentclass{article}
\begin{document}
\begin{displaymath}
\left< A \middle| B \right>
\end{displaymath}
\end{document}
---------- end of text.tex ---------
The following command works on this file to obtain xhtml output
with math represented by images:
/usr/share/tex4ht/xhlatex test.tex
However, if I try to obtain xhtml+mathml with the following command:
/usr/share/tex4ht/xhmlatex test.tex
then TeX errors occur during compilattion (all 3 runs), the first
of which is
! Missing } inserted.
<inserted text>
}
l.5 \left< A \middle
| B \right>
?
The log file is at the end of this email.
The following patch seems to solve the problem.
I strongly recommend to check this patch because I am neither an
expert in MathML, nor do I understand the code of mathml.4ht.
The patch is only for the part of mathml.4ht supporting LaTeX,
similar pacth should apply to the part supporting plain TeX.
The idea of the patch:
I more or less copied the support for \bigm and modified it for
\middle. As for MathML output my idea is that \middle should
produce the same as \bigm except that the mathsize attribute is
replaced with stretchy="true". (This is to indicate that the height
of the delimiter after \middle should be adjusted to the formula.)
