Hello,
I am rather new to docbook, but I have been successful using docbook (installed in Ubuntu 13.10) except for MathML content. Any math formatting is missing in the html output, and the pdf output is totally lacking the math content (not only the formatting).
Can you please check the detailed description below and suggest how I can start working with MathML content to produce both html pages and printed documents with nicely formatted formulas?
I have installed the following packages in ubuntu 13.10:
$sudo apt-get install xsltproc docbook-xsl docbook-defguide fop docbook-xsl-doc-pdf docbook-mathml
I am trying to process the following example (from http://www.docbook.org/tdg5/en/html/_any.mml.html) into html and
pdf:
test.xml:
--------------------------------------------------------
<article xmlns='http://docbook.org/ns/docbook'
xmlns:mml="http://www.w3.org/1998/Math/MathML">
<title>Example mml-math</title>
<informalequation>
<mml:math>
<mml:msup>
<mml:mi>x</mml:mi>
<mml:mn>3</mml:mn>
</mml:msup>
</mml:math>
</informalequation>
</article>
--------------------------------------------------------
First I process test.xml into test.html with the following
output:
--------------------------------------------------------
$ xsltproc -o test.html /usr/share/xml/docbook/stylesheet/nwalsh/html/docbook.xsl test.xml
Note: namesp. cut : stripped namespace before processing Example mml-math
Note: namesp. cut : processing stripped document Example mml-math
$
--------------------------------------------------------
The equation shows as "x 3" in test.html (the superscript is ignored). Other MathML pages appear correctly in my firefox browser.
Next, I process test.xml into test.pdf with the following output:
--------------------------------------------------------
$ xsltproc -o test.fo /usr/share/xml/docbook/stylesheet/nwalsh/fo/docbook.xsl test.xml
Note: namesp. cut : stripped namespace before
processing Example mml-math
Note: namesp. cut : processing stripped document Example mml-math

The pdf file shows nothing but the title.
What is wrong? Do I need to install additional packages? Can you show a MathML example that renders correctly with the described setup?
Thank you
