match elements with namespace

ehsansad · October 11th, 2010, 03:49 AM

Hello,
I am using
<xsl:template match="my_element_name">
to get match my XML elements, the problem is that the elements all have namespaces so the will look like "ab:my_element_name". When I try to match it nothing will happen and I am only able to process the node when I take remove the namespace from the XML file and just process the "my_element_name".

this is the xsd file "extracted and changed"

Code:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="2.0" exclude-result-prefixes="xs xdt err fn" 
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                xmlns:xs="http://www.w3.org/2001/XMLSchema" 
                xmlns:fn="http://www.w3.org/2005/xpath-functions" 
                xmlns:xdt="http://www.w3.org/2005/xpath-datatypes" 
                xmlns:err="http://www.w3.org/2005/xqt-errors" 
                xmlns:be="http://some valid address">
	
  <xsl:output method="xml" indent="yes"/>
	<xsl:template match="/">
			<xsl:apply-templates/>
	</xsl:template>

  <xsl:template match="my_element_name">
    <!--create the element with its attributes-->
    <xsl:element name="my_new_element_name">
       <xsl:attribute name="my_attrib1">
        <xsl:value-of select="my_element_name2"/> 
       </xsl:attribute>
       <xsl:attribute name="my_attrib2"/>
       <xsl:attribute name="my_attrib3"/>
       
       
       <xsl:element name="my_other_new_element">
        <xsl:apply-templates/>
       </xsl:element>
    </xsl:element>
  </xsl:template>

 
</xsl:stylesheet>

with out namespace

Code:

<?xml version="1.0" encoding="UTF-8"?>
<my_element_name identifier="">
  <my_element_name2>some stuff</my_element_name2>
  .....
  .....
</my_element_name>

with namespace

Code:

<?xml version="1.0" encoding="UTF-8"?>
<ab:my_element_name identifier="" xmlns:ab="some address" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="some address">
  <ab:my_element_name2>be:soknadid</ab:my_element_name2>
  ....
  .....
  
  </ab:my_element_name>

why can't I process the elements with namespaces?

thanks,
es

You simply need to use the namespace to match the element as well:

Code:

<xsl:template match="ab:my_element_name">

where "ab" is a namespace prefix that matched the namespace on the input XML document.

This is why I am asking the question here, I did try to match the element wtih the namespace, but for some reason it just didn't find it and automaticlly used the default template to process the xml file. so I don't know is it to do with my namespace declaration or something else.

>I did try to match the element wtih the namespace,

But you haven't shown us the code you wrote when you tried this, so we can't tell you where it was wrong.

It is unclear from your examples what the actual namespace in your input XML - I'm not sure that "some address" is a valid namespace.

But whatever your input XML namespace - you simply need to define that in your XSLT and use it as I suggest. The prefix does not need to be the same, but the namespace must match exactly (case sensitivity as well).

sorry for wasting your time, I was using the same address for the namespace and the schemaLocation. But thanks for the replays.
