XSLT chaining or combining xsl:copy-of and xsl:copy - xslt

Question

I've got the following two XSL transforms that I would like to chain together in one XSL file.
The first transform:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:s0="http://schemas.xmlsoap.org/wsdl/">
<xsl:template match="/">
<xsl:copy-of select="/s0:definitions/s0:types/xs:schema"/>
</xsl:template>
</xsl:stylesheet>
And the second transform (using the output of the first as input):
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:s0="http://schemas.xmlsoap.org/wsdl/">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/xs:schema/xs:element[#name='ServiceAuth']"/>
<xsl:template match="/xs:schema/xs:import[#namespace='http://www.somecompany.com/serviceAuth/ ']"/>
</xsl:stylesheet>
What I'm aiming to accomplish with this, is to copy only the xs:schema node (and all it's children) from a WSDL whilst at the same time removing two nodes from inside the xs:schema node.
How do I chain these two together in one XSL or is there an even better way to accomplish the above objective?
Below is the WSDL input file that should serve as input to the first transform:
<s0:definitions name="CBS_GetUpgradeEligibility" targetNamespace="http://www.somecompany.com/" xmlns:s0="http://schemas.xmlsoap.org/wsdl/" xmlns:s1="http://www.somecompany.com/CBS_GetUpgradeEligibility/" xmlns:s2="http://www.somecompany.com/" xmlns:s3="http://schemas.xmlsoap.org/wsdl/soap/">

Answer 1

If you want a third stylesheet that compose those two performing the same transformation as:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:s0="http://schemas.xmlsoap.org/wsdl/">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/">
<xsl:apply-templates select="s0:definitions/s0:types/xs:schema"/>
</xsl:template>
<xsl:template match="xs:schema/xs:element[#name='ServiceAuth']"/>
<xsl:template match="xs:schema/xs:import[#namespace='http://www.somecompany.com/serviceAuth/']"/>
</xsl:stylesheet>
Then you need:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<xsl:import href="stylesheet2.xsl"/>
<xsl:import href="stylesheet1.xsl"/>
<xsl:template match="/">
<xsl:variable name="vFirst">
<xsl:apply-imports/>
</xsl:variable>
<xsl:apply-templates select="msxsl:node-set($vFirst)/node()"/>
</xsl:template>
</xsl:stylesheet>
Output:
<xs:schema targetNamespace="http://www.somecompany.com/CBS_GetUpgradeEligibility/" xmlns:s0="http://schemas.xmlsoap.org/wsdl/" xmlns:s1="http://www.somecompany.com/CBS_GetUpgradeEligibility/" xmlns:s2="http://www.somecompany.com/" xmlns:s3="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:auth="http://www.somecompany.com/serviceAuth/" xmlns:cbs="http://www.somecompany.com/CBS_GetUpgradeEligibility/" xmlns:esb="http://www.somecompany.com/esbTypes/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.somecompany.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xs="http://www.w3.org/2001/XMLSchema">

Answer 2

I haven't touched XSLT for quite some time - but I think you can do it iterativly instead of by applying templates.
Start by selecting /s0:definitions/s0:types/xs:schema - then go over all of it's children (<xsl:for-each ... If i recall correctly) and for each of them test if it is the node you want to omit. if not - use copy-of, otherwise just drop it
Also, if you run the XSLT using some java code, or ANY utility you can just pass the output of the 1st XSLT as the input of the 2nd XSLT.
Hope this helps.

Answer 3

Since the first stylesheet is just selecting what is processed by the 2nd -- not doing any transformation itself, can't you just change copy-of to apply-templates, and import the 2nd stylesheet ? ( You don't really need to do any chaining. )
<xsl:stylesheet

<xsl:import href="stylesheet-2.xsl" />
<xsl:template match="/">
<xsl:apply-templates select="/s0:definitions/s0:types/xs:schema"/>
</xsl:template>
