XSLT » Elements » xsl:copy
- Syntax:
- <xsl:copy
use-attribute-sets="name-list"
>
</xsl:copy>
The xsl:copy element copies the current node in the source document to the output. The copy has the same name, namespace, and type as the original node, but any attributes, children, and other descendants are not copied. (Note that you can apply this element recursively to copy attributes and children.)
The xsl:copy-of element can be used to copy a node set. Children are copied with this element.
A common use of this element is to make identity transformations.
Examples
Code:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/ | @* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>Output:
<?xml version="1.0" encoding="UTF-16"?>
<?xml-stylesheet type="text/xsl" href="xslt_example_copy.xsl"?>
