Subject:  Want to use XSLT to sort an XML Schema

Hello,

I have a huge XML Schema file consisting of xs:imports,
xs:simpleTypes, and xs:complexTypes.  It is out of alphabetical order,
making it very difficult to quickly find definitions of needed types.
Also, the simpleTypes are interspersed with the complexTypes, and I
would like to keep them separated as well.

I would like to use XSLT to sort the document, first by imports, then
by simpleTypes, and then by complexTypes, and for each the three
groups, to have them sorted alphabetically.

As for the stylesheet, this is the best I can come up with:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="schema">

   <xsl:for-each select="./import">
        <xsl:sort select="@namespace"/>
        <xsl:apply-templates select="."/>
   </xsl:for-each>

   <xsl:for-each select="./simpleType">
        <xsl:sort select="@name"/>
        <xsl:apply-templates select="."/>
   </xsl:for-each>

   <xsl:for-each select="./complexType">
        <xsl:sort select="@name"/>
        <xsl:apply-templates select="."/>
   </xsl:for-each>

</xsl:template>

<xsl:template match="import">
   <xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="simpleType">
   <xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="complexType">
   <xsl:copy-of select="."/>
</xsl:template>

</xsl:stylesheet>

And it's resulting in a huge blank file.  Oh well.  Does anyone know
what I'm missing here to get this to work?  Also, I'm not really
handling namespaces here, i.e., the elements are actually called
xs:import, xs:simpleType, etc.  What (if anything) do I need to do to
take care of the namespaces as well?

Thanks,
Glen
