first, you'll want to alphabetize the list based on city name so run this
stylesheet on the xml:

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

<xsl:template match="people"> 
  <people> 
  <xsl:apply-templates select="person"> <xsl:sort
select="city"/> </xsl:apply-templates>
  </people> 
</xsl:template> 

<xsl:template match="person"> 
	<person> 
	<city> <xsl:value-of select="city"/></city>
	<name> <xsl:value-of select="name"/></name>
</person> 
</xsl:template> 

</xsl:stylesheet> 

Then, do this:

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

<xsl:template match="people"> 

  <xsl:apply-templates select="person"/> 

</xsl:template> 

<xsl:template match="person"> 

<xsl:if test="not(preceding-sibling::person[1]/city=city)"> 

  <xsl:text disable-output-escaping="yes"> 
</xsl:text>  <!-- hard return to make it look pretty -->

  <xsl:value-of select="city"/> 

  <xsl:text disable-output-escaping="yes"> 
</xsl:text>  <!-- hard return to make it look pretty -->

</xsl:if> 

<xsl:value-of select="name"/> 

<xsl:text disable-output-escaping="yes"> 
</xsl:text>  <!-- hard return to make it look pretty -->

</xsl:template> 

</xsl:stylesheet>

Sorry for the subject line, I couldn't think of anything better :-) I'm
trying to do the following:

I have something like this xml:

<people> 
    <person> 
        <city> Amsterdam</city>
        <name> John Doe</name>
    </person> 

    <person> 
        <city> Amsterdam</city>
        <name> Jane Doe</name>
    </person> 

    <person> 
        <city> London</city>
        <name> Jim Doe</name>
    </person> 
</people> 

And would like this result in html:

Amsterdam
John Doe
Jane Doe

London
Jim Doe

I hope I'm making myself clear, I searched the archives for an answer but I
don't really know what I'm looking for...
