Lawrence WelschSubject: Using MathML with a new schema and with xsl
Author: Lawrence Welsch
Date: 05 May 2005 10:25 AM
I am building a new simple schema in which I would like to embed mathml code and mathml entities such as τ

The schemas I am creating are:

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:include schemaLocation="file:///c:/Documents and Settings/lwelsch/My Documents/My Directories/RobustOptimization/ObjectiveFunctionAndConstraintsXML/ModelProperties.xsd"/>
<xsd:element name="MachiningModel">
<xsd:complexType>
<xsd:all>
<xsd:element name="formulas" minOccurs="0">
</xsd:element>
<xsd:element name="experimentalData" minOccurs="0">
</xsd:element>
<xsd:element ref="ModelProperties"/>
</xsd:all>
</xsd:complexType>
</xsd:element>
</xsd:schema>

and

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="ModelProperties">
<xsd:complexType>
<xsd:all>
<xsd:element name="symbol" minOccurs="0">
</xsd:element>
<xsd:element name="commonName" type="xsd:string" minOccurs="0"/>
<xsd:element name="siUnits" minOccurs="0" type="xsd:string"/>
<xsd:element name="commonUmits" type="xsd:string" minOccurs="0"/>
<xsd:element name="sourceInModeling" type="xsd:string" minOccurs="0"/>
<xsd:element name="uncertaintyEstimateInModeling" type="xsd:double" minOccurs="0" default="NaN"/>
<xsd:element name="sourceInExperimentOrPrototype" type="xsd:string" minOccurs="0"/>
<xsd:element name="uncertaintyEstimateInExperiment" type="xsd:double" minOccurs="0" default="NaN"/>
</xsd:all>
</xsd:complexType>
</xsd:element>
</xsd:schema>

with the xml file

<?xml version="1.0"?>
<MachiningModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="file://c:\Documents%20and%20Settings\lwelsch\My%20Documents\My%20Directories\RobustOptimization\ObjectiveFunctionAndConstraintsXML\MachingModel.xsd">
<formulas/>
<experimentalData/>
<ModelProperties>
<symbol>
<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline" ENTITIES="http://www.w3.org/1998/Math/MathML" >
<mstyle mathsize="3em">
<mrow>
<mi>&tau;</mi>
</mrow>
</mstyle>
</math>
</symbol>
<commonName>Torque</commonName>
<siUnits/>
<commonUmits/>
<sourceInModeling/>
<sourceInExperimentOrPrototype/>
</ModelProperties>
</MachiningModel>

The &tau; is immediately rejected. I trust there is a simple way to fix this. Further I would like an xsl file such as

<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:a="http://www.w3.org/1998/Math/MathML" exclude-result-prefixes="a">
<xsl:output method="html"/>

<xsl:template match="/">
<html xmlns='http://www.w3.org/1999/xhtml'>
<head></head>
<body>The symbol is
<xsl:copy-of select="MachiningModel/ModelProperties/symbol"/>.
</body>
</html>
</xsl:template>

</xsl:stylesheet><!-- Stylus Studio meta-information - (c) 2004-2005. Progress Software Corporation. All rights reserved.

</metaInformation>
-->

to display

The symbol is <the symbol for tau>

This feels like it should be simple, but I am banging my head against the wall.

Hi Lawrence,
entities can only be declared in a DTD, so you need to include it in every XML file where you plan to use them.
For instance, in the case of the XML file you wrote, you can do

<!DOCTYPE MachiningModel [
<!ENTITY % mathml-dtd PUBLIC "-//W3C//DTD MathML 2.0//EN"
"http://www.w3.org/Math/DTD/mathml2/mathml2.dtd" >
%mathml-dtd;
]>
<MachiningModel ...

Hope this helps,
Alberto
