Re: [xsl] adding element in with general namespace prefix Wendell Piez Wed Feb 08 14:01:54 2012

Ram,

Maybe you want to use xsl:copy, which may do better for you. Most processors, when copying an element, will use the same prefix as the input document uses.

Or it may not: as Ken says, processors are not obliged to respect prefixes since a prefix is not properly part of the name, as formally defined; it is only a (local) binding mechanism.

If you are answering a requirement from a partner who does not understand this, you can, in XSLT 2.0, go to considerably more work to construct elements with namespaces, names and their prefixes generated dynamically, using XPath functions such as name(), prefix-from-QName(), and namespace-uri-for-prefix(). An XSLT stylesheet could generate a new header using whatever prefix the input uses, whatever it is -- although such a stylesheet will look pretty mysterious to the uninitiated.

But this is not trivial to do, and a lot of trouble to go to for something that matters only because someone thinks it matters. Even worse, if you are addressing a set of requirements that have never been articulated, which you have only because someone at some point might be unhappy about something ... well. That's a difficult problem to solve.

Cheers,
Wendell

A true XML application ignores the
namespace prefix and relies only
on the namespace URI associated with the namespace prefix.

Can you explain why it is important to you that the prefix
be the
same?  It is irrelevant.  This request is
equivalent to an XML-based
namespace-aware application:

    <giraffe:Envelope xmlns:giraffe="http://schemas.xmlsoap.org/soap/envelope/">

An XML application will still see the above as a SOAP
envelope.

It isn't broken.

I hope this helps.

Hi,
     I have a soap request like the following
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:con1="http://abc.com/DefService/">

    <soapenv:Header>


</soapenv:Header>

    <soapenv:Body>

    <con1:GetDefinition>


    <!--Optional:-->


    <con1:Request><con1:Id/>


    </con1:Request>

    </con1:GetDefinition>

    </soapenv:Body>
</soapenv:Envelope>

I wanted to add ws:security with username credentials to
the request
like the following.



<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:con="http://wellpoint.com/esb/context"
xmlns:con1="http://abc.com/DefService/>
<soapenv:Header>
<wsse:Security
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
   <wsse:UsernameToken>

<wsse:Username>abcd</wsse:Username>

<wsse:Password>ramkurra</wsse:Password>
   </wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
<soapenv:Body>
     <con1:GetDefinition>
          <con1:Id/>

    </con1:Response>
     </con1:GetDefinition>
</soapenv:Body>
</soapenv:Envelope>


i tried with the following piece of code

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
      <xsl:copy>

    <xsl:apply-templates
select="@*|node()"/>
     </xsl:copy>

</xsl:template>
<xsl:template
match="/*[local-name()='Envelope']/*[local-name()='Header']">
<soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<wsse:Security
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken>
     <wsse:Username>
abc</wsse:Username>
     <wsse:Password>
xya</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
</xsl:template>
</xsl:stylesheet>

      i get the result as expected,
but my problem is when client
sends the request with different namespace name rather
than
soapenv:Header, like s:Header, the following line of
code will
still put soapenv:Header in the result
<soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

     I wanted to make this namespace prefix is
more of generalized
manner, which picks from request.
        So any idea how to fix
it.
