Re: [docbook-apps] include MathML files with the help of XSL

[Zoltán János Jánosi]

*Is there any single way to use the same method for generating PDFs?
(instead of HTML)*

I modified the method described earlier to generate PDF files with MathML
equations, but I didn't succeed.
*
Attempt one:*

   - I just changed the import href link from HTML to FO

*Content of the transformation XSL file: (**PDF_MathML.xsl**)
*
*<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform";>
*
* <xsl:import href="./docbook-xsl-1.77.1/fo/docbook.xsl"/>

    <xsl:output method="html" encoding="utf-8" indent="yes" />
    <xsl:template match="inlineequation | equation | informalequation">

        <xsl:variable name="id" select="@id"/>
        <xsl:variable name="mathml" select="concat('math/',$id, '.math')"/>

        <xsl:apply-templates select="document($mathml,.)/*"/>
    </xsl:template>
</xsl:stylesheet>*

I used Apache-FOP on Windows:
*fop.bat -c conf/fop.xconf -xml DSP_korrekted_2_abrak.xml -xsl
PDF_MathML.xsl -param body.font.family Times-Roman -param title.font.family
Times-Roman -pdf manual.pdf*

It gave me some errors related to missing fo: namespace. (or maybe root? I
cant remember well)
*
Attempt two:*

   - I modified the fo/math.xsl file, and included the following lines:

*<xsl:template match="inlineequation | equation | informalequation">
    <xsl:variable name="id" select="@id"/>
    <xsl:variable name="mathml" select="concat('math/',$id, '.math')"/>
    <xsl:apply-templates select="document($mathml,.)/*"/>
</xsl:template>*

It gave me a bunch of MathML-related warnings:

   - WARNING: Unknown formatting object "{http://www.w3.org/1998/Math/MathML}
   etc. etc.

And then a bunch of MathML files not found:

   - WARNING: Page xxiv: Unresolved ID reference "Eq_1096" found.

Ideas appreciated
