Hi Folks,

I want to transform this:

<xs:attribute name="test" />

to this:

<xs:attribute name="test" type="xs:anySimpleType" />

Here is the code that I tried:

<xsl:template match="xs:attribute">
<xsl:copy-of select="@*" />
<xsl:attribute name="type"><xsl:value-of select="QName('http://www.w3.org/2001/XMLSchema', 'anySimpleType')" /></xsl:attribute>
<xsl:sequence select="node()" />

Unfortunately that code produces this:

<xs:attribute name="test" type="anySimpleType" />

Notice that there is no prefix on anySimpleType.

What's the best way to accomplish my objective?

I want the prefix on anySimpleType to match the prefix on the <attribute> element, whether it be xs: or xsd: or anything else.

Retrieve it from the namespace axis:

(untested; assumes the default namespace is not the XSD namespace)
<xsl:attribute name="{name(namespace::*[.='http://www.w3.org/2001/XMLSchema'])]}:anySimpleType"
<xsl:copy-of select="node()"/>

or in XSLT 2.0:

<xsl:attribute name="{prefix-from-QName(node-name(.))}:anySimpleType"
  <xsl:copy-of select="node()"/>

Remember that node-name(.) gives the QName of the name of the current node, not the name string of the name of the current node.

I hope this helps.
