Sure, just add an extra key and an if test around the value-of to check
if it's the first occurance of that value:

<xsl:key name="cities" match="City" use="."/>

and the if test:

<xsl:if test="generate-id(ancestor::Community/City) =
generate-id(key('cities',ancestor::Community/City)[1])">
  <span><xsl:value-of select="ancestor::Community/City"/></span>
</xsl:if>

Now, this might fail at the moment because I'm guessing at the structure
of your xml, if its anything other that one <City> per <Community> then
you will need to adjust it.
