XSLT XML-HTML Transformation using grouping

K

Kevin Brown

Is there anyway to generate this type of resulting HTML table from
this XML using XSLT? Basically I need to be able to consult 2 trees of
data to generate the HTML, but I have not been able to figure out how
to do so. There is supposed to be a way of using templates and the key
function to do grouping, but can it be done with 2 different trees? If
so, are there any examples of such things

Thanks for any help,

Kevin

Hi Kevin,

The only distinct/grouping I can see if the values of @presence?

Try something like...

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:eek:utput method="html" indent="yes"/>
<xsl:key name="kDistinctPresence" match="element.for.housework.def"
use="@presence"/>

<xsl:template match="/">
<html>
<body>
<xsl:variable name="chefs"
select="/housework.definition/sequence.def.list/sequence.def/sequence.def.ro
le"/>
<table border="1">
<!-- do the chef header row -->
<tr>
<th/>
<xsl:for-each select="$chefs">
<th>
<xsl:value-of select="@role"/>
</th>
</xsl:for-each>
</tr>
<!-- now do the rows for each distinct @presence -->
<xsl:apply-templates
select="/housework.definition/element.for.housework.def.list/element.for.hou
sework.def[generate-id() =
generate-id(key('kDistinctPresence',@presence))]">
<xsl:with-param name="chefs" select="$chefs"/>
</xsl:apply-templates>
</table>
</body>
</html>
</xsl:template>

<xsl:template match="element.for.housework.def">
<xsl:param name="chefs"/>
<xsl:variable name="this-presence"
select="key('kDistinctPresence',@presence)/@element.name"/>
<tr>
<th align="right">
<xsl:value-of select="@presence"/>
<xsl:text>:</xsl:text>
</th>
<!-- now do columns for each chef with this @presence value -->
<xsl:for-each select="$chefs">
<td>
<!-- look for matches withing this chef of the current @presence -->
<xsl:for-each select="element.for.sequence.def.role/@element[. =
$this-presence]">
<xsl:value-of select="."/>
<xsl:if test="position() != last()">
<br/>
</xsl:if>
</xsl:for-each>
</td>
</xsl:for-each>
</tr>
</xsl:template>
</xsl:stylesheet>

Why don't you convert your XML into arrays, ie.
must=( make.pizza pour.milk )
maybe=( make.orange.juice make.ice.cream make.martini )
never=( make.apple.pie )
and
chef1=( make.pizza pour.milk make.orange.juice )
chef2=( make.ice.cream make.apple.pie )
chef3=( make.martini )

Then, you can cross-check as you print them out.
