Re: [xsl] selecting nodes - syntax?

[Oleg Tkachenko <olegt at multiconn dot com>]

Hello Denis!

Try the following:

<xsl:key name="akey" match="list/a" use="@code"/>
<xsl:template match="b">
	<xsl:variable name="selected">
		<xsl:for-each select="a">
			<xsl:sort select="key('akey', @code)/@priority" 	order="ascending" 
data-type="number"/>
			 <xsl:if test="position() = 1">
				<xsl:value-of select="@code"/>
			</xsl:if>
		</xsl:for-each>
	</xsl:variable>
	selected[<xsl:value-of select="$selected"/>]
</xsl:template>
