IdentityXSLT

The identity XSLT stylesheet

The identity stylesheet takes a source XML document and produces as the result document an exact copy of the input.

Here is the stylesheet:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="3.0">

  <xsl:template match="*|@*">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

</xsl:stylesheet>

To get this working, we need:

• matching attributes
• attribute pattern
• attribute nodes
• built-in templates
• template priorities
• xsl:copy element
• Union XPath operator
