xsl:perform-sort

Takes a sequence as its input and produces a sorted sequence as its output.

Category: instruction
Content: ( xsl:sort+ , sequence-constructor )
Permitted parent elements: any XSLT element whose content model is sequence-constructor; any literal result element

Attributes

select?

expression

The input sequence may be defined either by an expression within the optional select attribute, or by the enclosed sequence constructor.

Details

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.

Examples

<xsl:perform-sort select="//BOOK"> <xsl:sort select="author/last-name"/> <xsl:sort select="author/first-name"/> </xsl:perform-sort>
