Hi Garvin,
if your using xslt 2.0 it's pretty easy:
<xsl:for-each-group select="//edge" group-by="@source">
<xsl:for-each-group select="current-group()" group-by="@target">
<xsl:copy>
<xsl:copy-of select="@*"/>
</xsl:copy>
</xsl:for-each-group>
</xsl:for-each-group>
if your using 1.0 you may have to wait for someone with more knowledge of keys.

That wouldn't really work either. That would just assure you didn't
spit out a duplicate of the preceding record.
Someone will surely followup with more comprehensive suggestions about
xsl:key. I'd research it until then. =)
