[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Recursive selection, elegantly
 Hi Stephen,
I would have written something like this -
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:template match="/root">
<html>
<head>
<title/>
</head>
<body>
<table>
<tr>
<xsl:apply-templates select="menu[@ref =
'main_menu']/item"/>
</tr>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="menu/item">
<xsl:call-template name="x-page">
<xsl:with-param name="resource"
select="@resource"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="x-page">
<xsl:param name="resource"/>
<xsl:variable name="x-name"
select="/root/page[@about = $resource]/name"/>
<xsl:variable name="y-name"
select="/root/category[@about = $resource]/name"/>
<td>
<a href="{$resource}">
<xsl:value-of select="$x-name"/><xsl:value-of
select="$y-name"/>
</a>
</td>
</xsl:template>
</xsl:stylesheet>
Regards,
Mukul
