XSLT 2.0 template matching - strip all attributes which are not in the desired namespace

StackOverflow https://stackoverflow.com/questions/8544394

Question

I have an XML with differently namespaced attributes - it's basicly a kind of extended XHTML. I want to dump all the non-xhtml namespaced attributes.

Examplary source XML:

<html>
  <body>
    <p class="test" xy:foo="true">blah</p>
  </body>
</html>

At the moment, i have the following XSLT template:

<xsl:template match="@*">
    <xsl:choose>
        <xsl:when test='namespace-uri()="http://www.w3.org/1999/xhtml"'><xsl:copy-of select="."/></xsl:when>
        <xsl:otherwise></xsl:otherwise>
    </xsl:choose>
</xsl:template>

Desired output XML:

<html>
  <body>
    <p class="test">blah</p>
  </body>
</html>

But it doesn't seem to match, because i get an output XML completely without attributes. I have the feeling that namespace-uri() does not work as expected. Any ideas?

Was it helpful?

Solution

The attributes on XHTML elements (like your class one) are attributes in no namespace, not in the XHTML namespace. So use

<xsl:template match="@*[namespace-uri() != '']"/>

plus the identity transformation template.
