Namespace question

Clemensl · October 21st, 2010, 07:24 AM

I fail to understand how the XSLT processor processes my XSLT. Using the following XSLT...

PHP Code:


			
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:output method='xml' />
    <xsl:template match="/">
        <Envelope>
            <soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
                <ns1:SessionHeader soapenv:mustUnderstand="0" xmlns:ns1="urn:enterprise.soap.sforce.com">
                <ns2:sessionId xmlns:ns2="urn:enterprise.soap.sforce.com"><xsl:value-of select="//session/sessionid" /></ns2:sessionId>
                </ns1:SessionHeader>
            </soapenv:Header>
            <soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
                <logout xmlns="urn:enterprise.soap.sforce.com" />
            </soapenv:Body>
        </Envelope>
    </xsl:template>
</xsl:stylesheet>

... executed on this XML:

PHP Code:


			
<?xml version="1.0" encoding="UTF-8"?>
<partnersystemtype systypeid="0af004ea-f3a2-4f54-bf28-44407e2c19cc"
    systypename="WS Salesforce PST" systypeversion="12">
    <session>        
             <sessionid>1234</sessionid>
    </session>
</partnersystemtype>

produces the following output:

PHP Code:


			
<?xml version="1.0" encoding="UTF-8"?>
<Envelope>
    <soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
        <SessionHeader xmlns:ns1="urn:enterprise.soap.sforce.com"
            soapenv:mustUnderstand="0">
            <sessionId xmlns:ns2="urn:enterprise.soap.sforce.com">1234
            </sessionId>
        </SessionHeader>
    </soapenv:Header>
    <soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
        <logout xmlns="urn:enterprise.soap.sforce.com" />
    </soapenv:Body>
</Envelope>

Ok, but I want to have those namespaces ns1 and ns2 placed where I have placed them in the XSLT (i.e. <ns2:sessionId ... and <ns1:SessionHeader ...). With the current output the target web service cannot find the sessionId node because it seems to be in the wrong namespace (I could be in error about this, though). I probably failed to completely grasp the concept of namespaces. I would be very glad if you can give a short explanation why ns1: and ns2: does not appear in the output.

The output I want to have looks like this:

PHP Code:


			
<?xml version="1.0" encoding="UTF-8"?>
<Envelope>
    <soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
        <ns1:SessionHeader xmlns:ns1="urn:enterprise.soap.sforce.com"
            soapenv:mustUnderstand="0">
            <ns2:sessionId xmlns:ns2="urn:enterprise.soap.sforce.com">1234
            </ns2:sessionId>
        </ns1:SessionHeader>
    </soapenv:Header>
    <soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
        <logout xmlns="urn:enterprise.soap.sforce.com" />
    </soapenv:Body>
</Envelope>

Thank you very much

Which XSLT processor do you use? Have you tried a different processor to check and compare the result?

Clemensl · October 21st, 2010, 08:45 AM

Oh sorry, forgot the most important thing.

I am using Saxon 9.

I just tried it with the online xslt processor here: http://www.shell-tools.net/index.php?op=xslt

and it turned out to be ok...

I thought it was an issue with the code...

Mmmh... do you know a workaround for saxon?

I tried your stylesheet (added indent="yes" on xsl: output to be able to read the result) against the input you posted with Saxon 9.2.1.5 HE Java (from the command line) and get the following result:

Code:

<Envelope>
   <soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
      <ns1:SessionHeader xmlns:ns1="urn:enterprise.soap.sforce.com" soapenv:mustUnderstand="0">
         <ns2:sessionId xmlns:ns2="urn:enterprise.soap.sforce.com">1234</ns2:sessionId>
      </ns1:SessionHeader>
   </soapenv:Header>
   <soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
      <logout xmlns="urn:enterprise.soap.sforce.com"/>
   </soapenv:Body>
</Envelope>

That looks fine to me.

Yeah, same here. Using Saxon 9.1.0.2 Basic from Kernow for Saxon I see what Martin sees.

Clemensl · October 21st, 2010, 09:06 AM

Ok, thank you very much

I've updated to saxonb9-1-0-8j and it works now

I should be more confident about my xslt skills

Have a nice day
