Hi,
That stylesheet works outside of the browser, so it
seems to be an issue with how the browser loads and processes a
stylesheet. Can you get the browser to work without any stylesheet
customization, using the stock DocBook XSL stylesheet (without MathML
processing)? I've never had much luck getting browsers to process the
DocBook XSL stylesheets.

It doesn't seem to work for me.
I had to put this line right
after the xls namespace declaration line.
Now it drops an "unknown
error".
To reproduce the error, follow these steps:
download the 3 attached files into one directory
extract the DocBook xslt files into a subdirectory called
"docbook-xsl-1.76.1"
open the file called "MathML_XSLT_teszt.xml" in a browser (I use
FireFox)

Hi Zoltán,
I assumed you were developing a
customization layer of DocBook XSL. Your test stylesheet does not
import the DocBook XSL stylesheet, and so the templates matching on the
mathml elements are not available to the processor. If you add this to
the top of your test stylesheet, it will work:
<xsl:import
href=""/>
Now
the templates matching on mml:* are imported and can copy the MathML
elements through.
You also said:
but in my files, there are no mml namespace
given.
But in your Eq_0005.xml file, you do
specify the MathML namespace on the <math>
element:
<math xmlns="http://www.w3.org/1998/Math/MathML">
When
that file is opened by the document() function, that namespace is respected
and those mathml templates will be applied to those elements.

Problem 1:
All of the
MathML XML elements are missing.
Problem 2:
You wrote something
about DocBook MML template match and I couldn't really understand what
should I do with that:
You might want to add some error checking to this
code. You can use
xsl:apply-templates here because the DocBook
stylesheets already have
templates matching on MathML elements, and
they just copy the elements
through to the output. In html/math.xsl
you will find:
<xsl:template match="mml:*"
xmlns:mml="http://www.w3.org/1998/Math/MathML">
<xsl:copy>
<xsl:copy-of
select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
It
seems to me really usable (just copying the MathML objects), but in my
files, there are no mml namespace given.

OK, I'll do.

OK. If it works, please post your reply to the

Thanx Bob, you are right about what I originally
wanted.
Thanx for the answer, soon I'll try it!
2012/6/14 Bob
Stayton <>:
I think the requestor wanted to do this without
modifying the XML files to
add the references to the MathML
files:
dynamically pull in MathML files (by their
ID)
That's why he was trying to use
XInclude in XSL. However, XInclude cannot
be used inside an XSLT
stylesheet because XSLT processors do not recognize
it or process
it. The XInclude step is performed when the files are parsed
by the
XML parser, before the stylesheet sees the XML.
But a
stylesheet can use the XSLT document() function to open and
include
other content. Something like this would
work
<xsl:template
match="inlineequation">
<xsl:variable name="id"
select="@id"/>
<xsl:variable name="mathml"
select="concat($id, '.xml')"/>
<xsl:apply-templates
select="document($mathml,.)/*"/>
</xsl:template>

The first
thing I see is that you need to include the mathml namespace
in
your customization
layer
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:mml="http://www.w3.org/1998/Math/MathML"
xmlns:xi="http://www.w3.org/2001/XInclude">
Elements
for the MathML namespace should be prefixed with the prefix
you
chose (mml in the case above). Same thing with the XIncllude
elements,
they
have to be on their own namespace
(xi)
Each ID has to be unique. Otherwise when inserting the
MathML equation the
XSLT processor will throw an error for
duplicate IDs
Using the code you provide below I would do
something like this:
<inlineequation
id="Eq_0005">
<inlinemediaobject>
<imageobject>
<imagedata
fileref="math/Eq_0005.gif"/>
</imageobject>
<textobject>
<xi:include
href=""http://docbook.org/tdg51/en/html/inlinemediaobject.html"
target=_blank>http://docbook.org/tdg51/en/html/inlinemediaobject.html)
so the order in
which you put them may be important.
Using
xincludes may also change the way in which you process
your
documents.
Look at Bob Stayton's book for how to
pre-process your document with
xincluded content (http://www.sagehill.net/docbookxsl/Xinclude.html)

Hi
all!
My question:
Is there any way (with XSLT) to
dynamically pull in MathML files (by their
ID) and put them into
the XML/HTML files?
The situation is the following:
I
have a DocBook 4.4 XML file with equation objects in it.
Every
equation object has a unique ID.
For every equation ID belongs to 2
files, one MathML 2.0 XML file and a
graphics version.
Both
filename is constructed from the equation ID+extension.
The
graphics version is linked by the imagedata tag.
The source
equation looks like this: (DocBook
4.4)
<para>
<inlineequation
id="Eq_0005">
<inlinemediaobject>
<imageobject>
<imagedata
fileref="math/Eq_0005.gif"/>
</imageobject>
</inlinemediaobject>
</inlineequation>
<para>
I'd
like to dynamically transform the equation object to include
the
MathML
version rather than the graphics version. I tried to
transform the DocBook
document into XHTML and HTML5, and use
xinclude to include the MathML XML
files, but didn't succeed
yet.
It should look something like this at the end: (I
think)
<p>
<math>
<mrow>
<mi>a</mi>
<mo>⁢</mo>
<msup>
...
</math>
</p>
What
I have tried yet:
Here is a simple XSLT to get the equation
ID:
<?xml version="1.0"
encoding="UTF-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output
method="html"/>
<xsl:template
match="inlineequation">
The ID of equation is <xsl:value-of
select="@id"/>
</xsl:template>
</xsl:stylesheet>
Then
I tried to use the xinclude and put into the XSLT but none of
them
seemed to work.
Any ideas appreciated.
Thanx in
advance!
