Sorting

Sorting chooses an order for xsl:apply-templates and xsl:for-each (default: document order):

<xsl:sort select="expression" .../>;
a sequence of xsl:sort elements placed in xsl:apply-templates or xsl:for-each defines a lexicographic order

Some extra attributes:

order="ascending/descending"
lang="..."
data-type="text/number"
case-order="upper-first/lower-first"

Example:

<xsl:template match="personlist"> <xsl:apply-templates select="person"> <xsl:sort select="name/family"/> <xsl:sort select="name/given"/> </xsl:apply-templates> </xsl:template>

This template rule processes a list of persons, sorted with family name as primary key and given name as secondary key.
