[xsl] Return the max value of a set of nodes using FLWR

[Philip Vallone <philip.vallone@xxxxxxxxxxx>]

Hi,

How can I return the max value of a set of nodes using FLWR? In this example I
want to return:

3
2
0

input:

<data>
	<set>
		<changenumber>0</changenumber>
		<changenumber>3</changenumber>
		<changenumber>0</changenumber>
	</set>
	<set>
		<changenumber>0</changenumber>
		<changenumber>2</changenumber>
		<changenumber>1</changenumber>
	</set>
	<set>
		<changenumber>0</changenumber>
	</set>
</data>

XSLT 2.0

<xsl:sequence select="for $x in changenumber return number(max($x))"/>

Thanks,

Phil
