Takes a sequence as its input and produces a sorted sequence as its output.
Available in XSLT 2.0 and later versions. Available in all Saxon editions.
- Category: instruction
- Content: (
xsl:sort+ , sequence-constructor )
- Permitted parent elements: any XSLT element whose content model is sequence-constructor; any literal result element
- The input sequence may be defined either by an expression within the optional
selectattribute, or by the enclosed sequence constructor.
The sort criteria are specified using
xsl:sort elements as children of
xsl:perform-sort, in the usual way.
It's often useful to use
xsl:perform-sort inside a stylesheet function; the function can return the sorted sequence as its result, and can be invoked directly from an XPath expression.
<xsl:perform-sort select="//BOOK"> <xsl:sort select="author/last-name"/> <xsl:sort select="author/first-name"/> </xsl:perform-sort>
