Showing node-level members of a global set

[ion]

Hi! I'm struggling with doing this in an elegant way -- I'll get my
XSLT books out of storage this weekend, but for now I could use some
help.
<bedknob>
<broomstick>
<bippity>boppity</bippity>
</broomstick>
<broomstick>
<bippity>boppity</bippity>
<bippity>boo</bippity>
</broomstick>
</bedknob>
I'd like to get the complete list of bippities, then compare the
bippities of each broomstick to them, and make a mark for each present
member of the complete set of bippities in a particular broomstick,
like
<table>
<thead>
<tr>
<th>boppity
</th>
<th>boo
</th>
</tr>
</thead>
<tbody>
<tr>
<td>X
</td>
<td>
</td>
</tr>
<tr>
<td>X
</td>
<td>X
</td>
</tr>
</tbody>
</table>

OK. So, I use a Muenchian sort to get the unique list of bippities for
the thead element, but then to do the rows in the body, I have to go
through it again, and check each member against the set of present
values. I'm thinking of something like taking the intersection and
looking for count() = 2, but I'm having trouble making it happen.

Can you help me?

I have no idea if this will conform to your idea of elegance (it uses
plain dumb for-each loops), but this solution seems to work:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>

<xsl:key name="b" match="bippity" use="."/>
<xsl:variable name="bip"
select="//*[generate-id()=generate-id(key('b',.)[1])]"/>

<xsl:template match="bedknob">
<table>
<thead>
<tr>
<xsl:for-each select="$bip">
<th><xsl:value-of select="."/></th>
</xsl:for-each>
</tr>
</thead>
<tbody>
<xsl:apply-templates select="broomstick"/>
</tbody>
</table>
</xsl:template>

<xsl:template match="broomstick">
<xsl:variable name="this" select="bippity"/>
<tr>
<xsl:for-each select="$bip">
<td>
<xsl:if test=".=$this">X</xsl:if>
</td>
</xsl:for-each>
</tr>
</xsl:template>

</xsl:stylesheet>
