Hi,

Very roughly, you can go:

<!-- global to your stylesheet -->
<xsl:key name="att-by-name" match="Attendance"
         select="concat(LastName,' ',FirstName)" />
...
<!-- in a template somewhere -->
<xsl:variable name="varName" select="concat(
                               current()/LastName,' ',
                                 current()/FirstName)" />
...
<xsl:apply-templates select="key('att-by-name',$varName)" />


Maybe you want to refine this further if the format of the variable names is
variable too (WRT to upper-/lowercase), but this should get you going.

Hope this helps!

Cheers,
