Webmaster in a Nutshell, Third Edition

Name

<xsl:copy-of>

Synopsis

The <xsl:copy-of> instruction inserts the result tree fragment identified by the select attribute into the output document. This copies not only the specific node or nodes identified by the expression, but also all those nodes’ children, attributes, namespaces, and descendants. (This is how it differs from xsl:copy.) If the expression selects something other than a node set or a result tree fragment (e.g., a number), then the expression is converted to its string value, and the string is output.

<xsl:copy-of
   select="expression"/>
