Random xmlns="" in output

stolte · February 24th, 2011, 01:42 PM

I have one more question that I am unable to resolve. I am finding empty xmlns attributes in my output:

<content xmlns="">
<item type="dummy">
test
</item>
</content>

This seems to happen for any outermost element defined by its own template:

<xsl:template match="content">
<content>
<item type="{@itemType}"><xsl:value-of select="."></item>
</content>
</xsl:template>

Please note that it doesn't add the xmlns to the <item> element, only the <content> element.

Well you haven't shown any of your XSLT code but I suspect you can fix the issue by putting

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns="yourTargetNamespaceGoesHere"
  version="1.0">

</xsl:stylesheet>

into your stylesheet's root element.

I omitted the stylesheet because it is quite long, I have shortened it for this example.

My issue is that I don't want the namespace (xmlns="") at all.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:saxon="http://saxon.sf.net/"
exclude-result-prefixes="xs saxon"
version="2.0">

<xsl:output method="xml" indent="yes" cdata-section-elements="description" name="xml"/>

<xsl:template match="/">
<xsl:apply-templates select="product">
</xsl:template>

<xsl:template match="product">

<xsl:result-document format="xml" href="{@id}/out.xml">
<xsl:apply-templates select="content"/>
</xsl:result-document>

</xsl:template>

<xsl:template match="content">
<content>
<item type="{@itemType}"><xsl:value-of select="."></item>
</content>
</xsl:template>

</xsl:stylesheet>

I can't tell what goes wrong with that stylesheet sample alone. Post enough information allowing us to reproduce the problem (i.e. input sample, XSLT processor version). Usually the problem occurs when people want to output XHTML for instance and then do it like this

Code:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">

  <xsl:template match="/">
     <html xmlns="http://www.w3.org/1999/xhtml">
        <body>
           <xsl:apply-templates/>
        </body>
     </html>
  </xsl:template>

  <xsl:template match="foo">
     <p>
       <xsl:apply-templates/>
     </p>
   </xsl:template>

</xsl:stylesheet>

as that way the "p" elements are created in no namespace inside of a "body" elements in the XHTML namespace and then the output has <p xmlns="">...</p> to ensure the "p" elements are output in no namespace. Moving the xmlns="http://www.w3.org/1999/xhtml" to the stylesheet root fixes that problem.

I don't see anything like that in your stylesheet sample so I am not sure why you get the xmlns="" in your output.

Martin,

That was my problem and adding the namespace to the stylesheet element solved it. Thank you for your help.
