Hello,

I am rather a beginner with xsl. What I am trying to do is to tranform the
input.xml file below with a xsl stylesheet to another xml-file.


input.xml:
<?xml version='1.0' encoding='UTF-8'?>
<TestReq xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
  <par1 xsi:length="20">par1</par1>
  <par2>par2</par2>
</TestReq>



When I use the stylesheet st1.xml, I get the output outputst1.xml



st1.xml:
<xsl:stylesheet version = '1.0'
   xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
   xmlns:xsi='http://www.w3.org/1999/XMLSchema-instance'>

<xsl:output method='xml' version='1.0' indent='yes' />

<xsl:variable name="stylesheet"
              select="document('')/xsl:stylesheet" />

<xsl:template match='/'>
      <xsl:apply-templates select="*"/>
</xsl:template>

<xsl:template match='*'>
   <xsl:element name='{name()}' namespace="http://www.xxx.com/yyy" >
      <xsl:copy-of select="$stylesheet/namespace::xsi" />
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

<xsl:template match="*[@xsi:length]">
   <xsl:element name='withlength-{name()}'>
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

</xsl:stylesheet>


outputst1.xml:
<?xml version="1.0" standalone="yes"?>
<TestReq xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns="http://www.xxx.com/yyy">
   <withlength-par1 xmlns="">par1</withlength-par1>
   <par2>par2</par2>
</TestReq>



You can see that the template match for the attribute xsi:length is
correctly matched (I figure because the version of xsi namespace in the
stylesheet is the same as that of the input file). When I use the stylesheet
st2.xml however, the template match for xsi:length is not handled at all
(apparently because the stylesheet does not have the same version of the xsi
namespace as the input: 2001 instead of 1999).



st2.xml:
<xsl:stylesheet version = '1.0'
   xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
   xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>

<xsl:output method='xml' version='1.0' indent='yes' />

<xsl:variable name="stylesheet"
              select="document('')/xsl:stylesheet" />

<xsl:template match='/'>
      <xsl:apply-templates select="*"/>
</xsl:template>

<xsl:template match='*'>
   <xsl:element name='{name()}' namespace="http://www.xxx.com/yyy" >
      <xsl:copy-of select="$stylesheet/namespace::xsi" />
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

<xsl:template match="*[@xsi:length]">
   <xsl:element name='withlength-{name()}'>
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

</xsl:stylesheet>


outputst2.xml:
<?xml version="1.0" standalone="yes"?>
<TestReq xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.xxx.com/yyy">
   <par1>par1</par1>
   <par2>par2</par2>
</TestReq>



I solved this by looking only at the local-name of the attribute, as shown
in stylesheet st3.xml



st3.xml:
<xsl:stylesheet version = '1.0'
   xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
   xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>

<xsl:output method='xml' version='1.0' indent='yes' />

<xsl:variable name="stylesheet"
              select="document('')/xsl:stylesheet" />

<xsl:template match='/'>
      <xsl:apply-templates select="*"/>
</xsl:template>

<xsl:template match='*'>
   <xsl:element name='{name()}' namespace="http://www.xxx.com/yyy" >
      <xsl:copy-of select="$stylesheet/namespace::xsi" />
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

<xsl:template match="*[@*[local-name()='length']]">
   <xsl:element name='withlength-{name()}'>
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

</xsl:stylesheet>


outputst3.xml
<?xml version="1.0" standalone="yes"?>
<TestReq xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.xxx.com/yyy">
   <withlength-par1 xmlns="">par1</withlength-par1>
   <par2>par2</par2>
</TestReq>



So my output is mainly correct, the only this is that an extra xmlns=""
appears in the tag withlength-par1. This can be removed by adding an extra
'namespace="http://www.xxx.com/yyy"' in the stylesheet as show below in
stylesheet st4.xml.



st4.xml:
<xsl:stylesheet version = '1.0'
   xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
   xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>

<xsl:output method='xml' version='1.0' indent='yes' />

<xsl:variable name="stylesheet"
              select="document('')/xsl:stylesheet" />

<xsl:template match='/'>
      <xsl:apply-templates select="*"/>
</xsl:template>

<xsl:template match='*'>
   <xsl:element name='{name()}' namespace="http://www.xxx.com/yyy" >
      <xsl:copy-of select="$stylesheet/namespace::xsi" />
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

<xsl:template match="*[@*[local-name()='length']]">
   <xsl:element name='withlength-{name()}'
namespace="http://www.xxx.com/yyy">
      <xsl:apply-templates/>
   </xsl:element>
</xsl:template>

</xsl:stylesheet>



Somehow I get the feeling that there should be an easier way to accomplish
this. Does anyone know how?



Kind regards,


Paul Vintges.
