Can I do this with XSLT?

[Billy Hause]

How do I extract a list of 'states' using XSLT?
I want each state listed only once. Can XSLT do this?
Any suggestions appriciated.
My XML looks like this (but with many more stores)...
<?xml version="1.0"?>
<stores>
<store storename="Rocky's Auto">
<state>CO</state>
</store>
<store storename="John Elway Used Cars">
<state>CO</state>
</store>
<store storename="Wild Pete's Used Cars">
<state>FL</state>
</store>
</stores>

Output should be something like this...
<states>
<state>CO</state>
<state>FL</state>
</states>

Hi !
You may do something like this...
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="stores">
<?xml version="1.0"?>
<states>
<xsl:apply-templates match="store"/>
</states>
</xsl:template>
<xsl:template match="store">
<state><xsl:value-of select="state"/></state>
</xsl:template>
</xsl:stylesheet>
I hope this is working & this will help you

Thanks, but that solution doesn't list each state only once. I need to eliminate duplicates.
Thanks anyway.

<xsl:template match="/">
<states>
<xsl:for-each select="//state">
<xsl:sort select="."/>
<xsl:if test="not(.=preceding::*)">
<state><xsl:value-of select="."/></state>
</xsl:if>
</xsl:for-each>
</states>
</xsl:template>

That worked! Thanks
