Hi All,

My friend Deepa is got stuck in a XSLT transform. She is using Xalan processor.

The input file contains some namespaces which should be removed in desired output file.

Below is the input file-
<ConfigDataFile xmlns="WiMAX-CAPC" xmlns:HHP="HHP" xmlns:CLM="CLM"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="WiMAX-CAPC ./updatedSchema/WiMAX-CAPC_NECB.xsd">
   <configData dnPrefix="String">
        <CLM:CLM>
<CLM:clAgentClientTypeDefinitionTable>
   <CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
   <CLM:clAgentClientType>100</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>

   </CLM:clAgentClientTypeDefinitionEntry>
<CLM:clAgentClientTypeMaxCountONE >test</CLM:clAgentClientTypeMaxCountONE>
<CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<CLM:clAgentClientType>100</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>200</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>
<CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<CLM:clAgentClientType>000</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>
</CLM:clAgentClientTypeDefinitionTable>
</CLM:CLM>
</configData>
</ConfigDataFile>


The XSLT(1.0) code, she is using -
<xsl:template match=”/”>
<xsl:for-each select=”descendant::*>
<xsl:if test=”name(ancestor::*[1])= ‘CLM:clAgentClientTypeDefinitionTable’ | name(ancestor::*[2])= CLM:clAgentClientTypeDefinitionTable’”>
<xsl:element name=”{name(.)}>
<xsl:copy-of select=”@*”/>
</xsl:element>
</xsl:for-each>
</xsl:template>


The output she is getting-
 <CLM:clAgentClientTypeDefinitionEntry xmlns:CLM="CLM" modemId="1" cageId="1">
<CLM:clAgentClientType>0hshj</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>
<CLM:clAgentClientTypeMaxCountONE xmlns:CLM="CLM">test</CLM:clAgentClientTypeMaxCountONE>
<CLM:clAgentClientTypeDefinitionEntry xmlns:CLM="CLM" modemId="1" cageId="1">
<CLM:clAgentClientType>100</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>200</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>
<CLM:clAgentClientTypeDefinitionEntry xmlns:CLM="CLM" modemId="1" cageId="1">
<CLM:clAgentClientType>000</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>

but she doesn't want the red color entries which are coming after transformation.(Means xmlns:CLM=”CLM” should be removed)

The desired output is like-
<CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<CLM:clAgentClientType>0hshj</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>
<CLM:clAgentClientTypeMaxCountONE >test</CLM:clAgentClientTypeMaxCountONE>
<CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<CLM:clAgentClientType>100</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>200</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>
<CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<CLM:clAgentClientType>000</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>


Is it possible to get the desired output using XSLT 1.0 or is there any way to do it in XSLT 2.0(using saxon or any other processor which supports XSLT 2.0).

Thanks

Manish

You can do this with a single template rule that does a recursive walk of the input tree:

<xsl:template match="*">
  <xsl:element name="local-name()">
    <xsl:copy-of select="@*"/>
    <xsl:apply-templates/>
  </xsl:element>
</xsl:template>

If your desired output contains the "CLM" prefix then that namespace prefix will have to be declared somewhere.

As your desired output is an XML fragment and not a full XML document (i.e. it has no single root element) then the namespace declaration must appear more than once.

Michael's example above will remove the namespace prefix "CLM" and hence will no longer require the namespace declaration - this might be what you are after.

Thanks Michael for you input.

She is saying after using code you wrote, she is getting the output without (CLM:) that is like-

<clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<clAgentClientType>0hshj</clAgentClientType>
<clAgentClientTypeMax>100</clAgentClientTypeMax>
</clAgentClientTypeDefinitionEntry>

but she wants the output to come like-

 <CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">
<CLM:clAgentClientType>0hshj</CLM:clAgentClientType>
<CLM:clAgentClientTypeMax>100</CLM:clAgentClientTypeMax>
</CLM:clAgentClientTypeDefinitionEntry>


Here is the copy of XSLT code which she has sent me-

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:xalan="http://xml.apache.org/xalan" xmlns:CLM="CLM" xmlns:HHP="HHP">
    <xsl:output indent="yes"/>
    <xsl:template match="/">
       <xsl:for-each select="descendant::*">
        <xsl:if test="name(ancestor::*[1])='CLM:clAgentClientTypeDefinitionTable' ">
            <xsl:element name="{name(.)}">
            <xsl:copy-of select="@*"/>
                </xsl:element>
                </xsl:if>
                </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Do you want any modification in above code to get desired output?

See my previous comment - you can't remove the namespace declaration if you want to keep the prefix. It would become invalid XML.

/- Sam Judson : Wrox Technical Editor -/

>but she wants the output to come like-

 <CLM:clAgentClientTypeDefinitionEntry modemId="1" cageId="1">

That output would not be valid XML according to the XML Namespaces specification, and XSLT does not allow you to create invalid XML.
