change namespace

nguna · January 14th, 2009, 12:00 PM

Hi,

I have the following xml

<Data xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"xmlns:icns="urn:NewBusiness_XXX"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<createdDate>11/12/2009 at 09:21:38</createdDate>
<product_code>ABC</product_code>
</Data>

I would like to change the namespace icns to urn:NewBusiness_ABC
i.e i would like to get the following.

<Data xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"xmlns:icns="urn:NewBusiness_ABC"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<createdDate>11/12/2009 at 09:21:38</createdDate>
<product_code>ABC</product_code>
</Data>

I have tried various methods but nothing works any hints ?

Do you use XSLT 2.0 or 1.0?

i'm using

XSLT 1.0

Here is an XSLT 1.0 stylesheet that does the trick here for me (tested with Saxon 6.5.5):

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:icns="urn:NewBusiness_ABC"
  version="1.0">
  
  <xsl:template match="@* | text() | comment() | processing-instruction()">
    <xsl:copy/>
  </xsl:template>
  
  <xsl:template match="*">
    <xsl:element name="{name()}" namespace="{namespace-uri()}">
      <xsl:copy-of select="document('')/xsl:stylesheet/namespace::*[local-name() = 'icns']"/>
      <xsl:copy-of select="namespace::*[not(local-name() = 'icns')]"/>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:element>
  </xsl:template>

</xsl:stylesheet>

Hi Martin,

Sorry i didn't explain clearly..
the new namespace should be a dynamic one
urn:NewBusiness_ABC
where ABC is the prodoct code from the xml

Martin Honnen · January 14th, 2009, 01:01 PM

I am not sure that is possible. With XSLT 2.0 there is an instruction http://www.w3.org/TR/xslt20/#creating-namespace-nodes to create a namespace node but I don't know how to achieve the same with XSLT 1.0.
Maybe someone else has an idea.

Just change this:

<xsl:element name="{name()}" namespace="{namespace-uri()}">

to compute the namespace URI that's needed, e.g.

<xsl:element name="{name()}"
namespace="urn:NewBusiness_{../productCode}">

Thanks Micheal,

The solution works if i have it in a seperate style sheet. But not i the following case

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"xmlns:icns="urn:NewBusiness_ATV"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
<xsl:template match="/">
<soapenv:Envelope>
<xsl:call-template name="buildSoapHeader"/>
</soapenv:Envelope>
</xsl:template>

<xsl:template name="buildSoapHeader">
<soapenv:Header>
<icns:IplusHeader>
<icns:freeFormatText>Sample Text</icns:freeFormatText>
</icns:IplusHeader>
</soapenv:Header>
</xsl:template>

<xsl:template match="@* | text() | comment() | processing-instruction()">
<xsl:copy/>
</xsl:template>

<xsl:template match="*">
<xsl:element name="{name()}" namespace="urn:TEST">
<xsl:copy-of select="document('')/xsl:stylesheet/namespace::*[local-name() = icns']"/>
<xsl:copy-of select="namespace::*[not(local-name() = 'icns')]"/>
<xsl:apply-templates select="@* | node()"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>

You can copy a namespace node to add an extra namespace declaration to an element, but that will never change the name of the element. The name of the element (its local name and namespace URI) are determined solely by the name and namespace attributes of the xsl:element instruction. If you need to compute the namespace URI, then the computation must be done in the namespace attribute, e.g.

namespace="{document('')/xsl:stylesheet/namespace::*[local-name() = icns']}"

(though that seems a pretty odd way to compute it, since you know at the time you write your stylesheet what namespaces it declares)

Thanks for the reply.

But after the transformation i'm loosing the prefix icns

i get the following..

<Print_Data xmlns="urn:Test"

i want to get the resulting xml with the prefix icns please explain how i can acheive this
