Here is my test setup:* ** DocBook 4.4 XML file:** **<?xml version='1.0' encoding='UTF-8'?> <?xml-stylesheet href="HTML5_MathML.xsl" type="text/xsl"?> <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN" "docbookV4.4/docbookx.dtd" []> <book xmlns:xi="http://www.w3.org/2001/XInclude";> <title/> <chapter> <title/> <para> <inlineequation id="Eq_0005"> <inlinemediaobject> <imageobject> <imagedata fileref="math/Eq_0005.gif"/> </imageobject> </inlinemediaobject> </inlineequation> </para> </chapter> </book>*
*The XSLT file (HTML5_MathML.xsl):* *<?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" encoding="utf-8" indent="yes" /> <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> <xsl:template match="/"> <xsl:text disable-output-escaping='yes'></xsl:text> <html> <body> <xsl:apply-templates/> </body> </html> </xsl:template> </xsl:stylesheet>* *MathML file (Eq_0005.xml):* * <math xmlns="http://www.w3.org/1998/Math/MathML";> <mrow> <msup><mi>a</mi><mn>2</mn></msup> <mo>+</mo> <msup><mi>b</mi><mn>2</mn></msup> <mo>=</mo> <msup><mi>c</mi><mn>2</mn></msup> </mrow> </math>* *Expected result:* <!doctype html> <html> <head> <meta charset="UTF-8"> </head> <body> * <math xmlns="http://www.w3.org/1998/Math/MathML";> <mrow> <msup><mi>a</mi><mn>2</mn></msup> <mo>+</mo> <msup><mi>b</mi><mn>2</mn></msup> <mo>=</mo> <msup><mi>c</mi><mn>2</mn></msup> </mrow> </math>* </body> </html> * Obtained result: (by opening the DocBook XML file in FireFox)* *<html>* *<body> x ( t ) = R e [ A ⋅ e j ( ω 0 ⋅ t + Φ ) ] </body>* *</html> **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.
