Why don't you just nest the loops instead of putting them adjacent to each other?

Consider this little stysheet (change 'root' to a proper name) :

<xsl:stylesheet version="1.0"

<xsl:output method="text"/>

<xsl:key name="occupant" match="occupant" use="unitid"/>

<xsl:template match="root">
<xsl:for-each select="unit">
	<xsl:variable name="unit" select="."/>
	<xsl:variable name="occupants" select="key('occupant',id)"/>
		<xsl:when test="$occupants">
			<xsl:for-each select="$occupants">
				<xsl:value-of select="$unit/name"/> | <xsl:value-of select="name"/>
			<xsl:value-of select="$unit/name"/> | Vacant

I had something like this (without using keys, as I just don't understand keys well enough other than to copy other people's examples :) ); the problem is that I was giving a simplified version of my problem. There are actually 7 or 8 columns per row, and it just seems that there must be a way that I don't have to have each column defined in both the when and the otherwise.
