RE: [xsl] Creating namespace attributes

["Michael Kay" <mike@xxxxxxxxxxxx>]

XSLT creates a result tree, not serialized XML: and in the tree model,
namespaces and attributes are quite distinct things. You need to create a
namespace node, not an attribute node.

In XSLT 2.0 this is easy, there is an xsl:namespace instruction which works
in a similar way to xsl:attribute.

In XSLT 1.0 it's more difficult. The only way to create a namespace node in
the result tree is by copying one either from the stylesheet or from a
source document. So the workaround is to create a temporary tree containing
an element in the relevant namespace, and then copy the namespace node from
that temporary tree (even this needs the xx:node-set() extension).

<xsl:template match="namespace">
<namespace>
<xsl:for-each select="*">
  <xsl:variable name="temp">
    <xsl:element name="{name(.)}:dummy" namespace="{.}"/>
  <xsl:variable>
  <xsl:copy-of select="xx:node-set($temp)//namespace::*"/>
</xsl:for-each>
</namespace>
</xsl:template>
