apply two consecutive xslt transformations - xslt

Question

I have two xslt transformations to apply to an xml message.
The first is to drop all namespaces and prefixes. here is the code :
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="#*|node()[not(self::*)]">
<xsl:copy/>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
The second one is to select elements from the output of the first :
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<onSale><xsl:value-of select="//entry/content/product_product/sale_ok" /></onSale>
<onlineOnly><xsl:value-of select="//entry/content/product_product/online" /></onlineOnly>
<name><xsl:value-of select="//entry/content/product_product/name" /></name>
<isbn><xsl:value-of select="//entry/content/product_product/isbn" /></isbn>
<price><xsl:value-of select="//entry/content/product_product/price" /></price>
<active><xsl:value-of select="//entry/content/product_product/active" /></active>
<format><xsl:value-of select="//entry/content/product_product/format" /></format>
<collection><xsl:value-of select="//entry/content/product_product/collection" /></collection>
<dateParution><xsl:value-of select="//entry/content/product_product/date_parution"/></dateParution>
<ean13><xsl:value-of select="//entry/content/product_product/ean13"/></ean13>
</xsl:template>
</xsl:stylesheet>
How I can apply the two of them in one xslt transformation without doing two transformation separately .
Thanks

I don't know which version of XSLT is supported in your environment, with XSLT 2.0 you can use
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="step1">
<xsl:apply-templates mode="step1"/>
</xsl:variable>
<xsl:template match="#*|node()[not(self::*)]" mode="step1">
<xsl:copy/>
</xsl:template>
<xsl:template match="*" mode="step1">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="node()|#*" mode="step1"/>
</xsl:element>
</xsl:template>
<xsl:template match="/">
<xsl:apply-templates select="$step1//entry"/>
</xsl:template>
<xsl:template match="entry">
<onSale><xsl:value-of select="content/product_product/sale_ok" /></onSale>
<onlineOnly><xsl:value-of select="content/product_product/online" /></onlineOnly>
<name><xsl:value-of select="content/product_product/name" /></name>
<isbn><xsl:value-of select="content/product_product/isbn" /></isbn>
<price><xsl:value-of select="content/product_product/price" /></price>
<active><xsl:value-of select="content/product_product/active" /></active>
<format><xsl:value-of select="content/product_product/format" /></format>
<collection><xsl:value-of select="content/product_product/collection" /></collection>
<dateParution><xsl:value-of select="content/product_product/date_parution"/></dateParution>
<ean13><xsl:value-of select="content/product_product/ean13"/></ean13>
</xsl:template>
</xsl:stylesheet>
I would further refactor however and write templates like
<xsl:template match="sale_ok">
<onSale>
<xsl:value-of select="."/>
</onSale>
</xsl:template>
If you use XSLT 1.0 you need an extension function to process the contents of a variable with apply-templates so doing
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exsl="http://exslt.org/common">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="step1">
<xsl:apply-templates mode="step1"/>
</xsl:variable>
<xsl:template match="#*|node()[not(self::*)]" mode="step1">
<xsl:copy/>
</xsl:template>
<xsl:template match="*" mode="step1">
<xsl:element name="{local-name()}">
<xsl:apply-templates select="node()|#*" mode="step1"/>
</xsl:element>
</xsl:template>
<xsl:template match="/">
<xsl:apply-templates select="exsl:node-set($step1)//entry"/>
</xsl:template>
<xsl:template match="entry">
<onSale><xsl:value-of select="content/product_product/sale_ok" /></onSale>
<onlineOnly><xsl:value-of select="content/product_product/online" /></onlineOnly>
<name><xsl:value-of select="content/product_product/name" /></name>
<isbn><xsl:value-of select="content/product_product/isbn" /></isbn>
<price><xsl:value-of select="content/product_product/price" /></price>
<active><xsl:value-of select="content/product_product/active" /></active>
<format><xsl:value-of select="content/product_product/format" /></format>
<collection><xsl:value-of select="content/product_product/collection" /></collection>
<dateParution><xsl:value-of select="content/product_product/date_parution"/></dateParution>
<ean13><xsl:value-of select="content/product_product/ean13"/></ean13>
</xsl:template>
</xsl:stylesheet>
On the other I wonder why we are getting lots of questions recently trying to eliminate namespaces or to ignore them, if you really want to do that with XSLT 2.0 then doing
<xsl:template match="*:sale_ok">
<onSale>
<xsl:value-of select="."/>
<onSale>
</xsl:template>
and so on suffices.
