I am having difficulties referencing all 3.
I have already written my XML,XSD and XSL but it doesn’t seem to work with the referencing.
Here is a simple example using the same referencing.

XSD:

 <?xml version="1.0"?>
 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
   targetNamespace="http://www.w3schools.com"
   xmlns="http://www.w3schools.com"
   elementFormDefault="qualified">

   <xs:element name="email">
     <xs:complexType>
       <xs:sequence>
         <xs:element name="to" type="xs:string"/>
       </xs:sequence>
     </xs:complexType>
   </xs:element>

 </xs:schema>

XML:

 <?xml version="1.0"?>
 <?xml-stylesheet type="text/xsl" href="email.xsl"?>

 <email
   xmlns="http://www.w3schools.com"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.w3schools.com email.xsd">

   <to>John</to>
 </email>

XSL:

 <?xml version="1.0" encoding="UTF-8"?>
 <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:template match="/">
    <html>
      <body>
        <xsl:for-each select="email">
          <h2>To</h2>
          <td><xsl:value-of select="John"/></td>
        </xsl:for-each>
      </body>
    </html>
  </xsl:template>

 </xsl:stylesheet>

    The XSLT does not work because your email element has a namespace, and to match an element with a namespace using an XPath you always have to explicitely declare a prefix and use it.

    You need to write the XSL like this:

    <?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:ws="http://www.w3schools.com"
  version="1.0"> 

  <xsl:template match="/"> 
    <html> 
      <body> 
        <xsl:for-each select="ws:email"> 
          <h2>To</h2> 
          <td><xsl:value-of select="ws:to"/></td> 
        </xsl:for-each> 
      </body> 
    </html> 

  </xsl:template>

    I am not sure what you are expecting from the XSD: it seems correct, but it won’t affect in any way the application of the XSLT.

    email is the root element in your XML, so you can have only one email element per XML file – probably you should have a different root element above it.

    Note also that you are generating dubious HTML: a <td> that is not inside a table.
