Transformation Problem
Hello
I am kind of new on working with XML and XSL transformation..
however i have worked with XSL transformation for a short time only..
i have a small problem which i am facing and i do not really understand what is causing although i think the problem has something to do with the namespace..
i try to transform a SOAP_Message XML file to a normal XML file and i can get the values below the Header..meaning inside the the body element...
my XSL transformation looks like below...
<xsl:template match="/">
<Root>
<xsl:value-of select="SOAP-ENV:Envelope/soapenv:Header/cmn:timeStamp"/>
<xsl:value-of select="SOAP-ENV:Envelope/soapenv:Header/ns:getReportResponse/response/companyResponse/responseHeader/cmn:languageCode" />
<xsl:value-of select="SOAP-ENV:Envelope/soapenv:Header/ns:getReportResponse/response/companyResponse/responseHeader/cmn:responseStatus" />
</Root>
the timeStamp can be retrieved easily but however the field responseStatus can not be retrieved..i get an empty element..
can someone please tell me what i am doing wrong??
i have tried to search for a nice reason and people have just hinted the namespace issue and i have not managed to clear reason like what is the cause exactly...
my sample XML message is below::
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<cmn:timeStamp xmlns:cmn="http://www.companyName.com/XMLSchema/compMain.xsd">123445+0001</cmn:timeStamp>
</soapenv:Header>
<SOAP-ENV:Body>
<ns:getReportResponse xmlns:ns="http://www.companyName.com/company/">
<response xmlns:fs="http://www.companyName.com/XMLSchema/Company_4.xsd" xmlns:cmn="http://www.companyName.com/XMLSchema/compMain.xsd" xmlns:pr="http://www.companyName.com/XMLSchema/details.xsd" xmlns="http://www.companyName.com/XMLSchema/compMain3.xsd" xsi:SchemaLocation="http://www.companyName.com/XMLSchema/compMain3.xsd">
<companyResponse>
<responseHeader>
<cmn:languageCode xmlns:cmn="http://www.companyName.com/XMLSchema/compMain.xsd">com</cmn:languageCode>
<cmn:state xmlns:cmn="http://www.companyName.com/XMLSchema/compMain.xsd">1</cmn:state>
</responseHeader>
</companyResponse>
</response>
thanks for help in advance

Start out with the so-called "identity transform":
<?xml version="1.0"?>
<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:stylesheet>
As step 1, run the transform, and look at the result to see the effect.
Then add the following rules one by one and repeat step 1 each time
around.
Add parsing and serialization instructions to get clean input and
output:
<xsl:strip-space elements="*"/><!-- for parsing -->
<xsl:output indent="yes"/><!-- for serialization -->
Replace the document element:
<xsl:template match="/*"><!-- document element -->
<Root>
<xsl:apply-templates select="*"/>
</Root>
</xsl:template>
Replace the cmn:state element, and here, you need to add the namespace
to the stylesheet, and if you don't want it in the output, then you
exclude it:
<xsl:stylesheet version="1.0"
xmlns:cmn="http://www.companyName.com/XMLSchema/compMain.xsd"
exclude-result-prefixes="cmn"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="cmn:state">
<child><xsl:apply-templates/></child>
</xsl:template>
Final touch, add a rule to filter out everything else:
<xsl:template match="*" priority="-0.4">
<xsl:apply-templates select="*"/>
</xsl:template>

Namespaces are just a mapping from prefixes to URIs (well, strings).
Not much to say. For XSLT, there are good sites and books:
* http://www.jenitennison.com/
* http://www.dpawson.co.uk/xsl/
* books by Jeni Tennison, Michael Kay, Evan Lenz, others
I hope this helps :-)

What's a normal XML file? :-)

Maybe that's because there is no cmn:responseStatus in your input?
Maybe you wanted to <xsl:copy-of select="//cmn:state"/> ?

It's easy to lose reason amidst such a namespace horror show as the one
you posted. A horror soap opera, more properly. Really looks like a
parody of SOAP. I counted nine namespaces, two of which are unused.
You may also want to check if you really want <xsl:value-of>, which
extracts the string value, or <xsl:copy-of>, which copies the nodes.
You can get a better answer if you tell us (or maybe the XSL-List at
Mulberrytech.com) what your desired output looks like.
