<xsl:for-each select="//CUSTOMER[not(.=preceding::CUSTOMER)]">
<xsl:value-of select="."/>
</xsl:for-each>

Don't try it with the new Microsoft product, it doesn't support "preceding".

> for example if i had the following xml document:
> 
> <SALESFORCE>
>      <SALESPERSON NAME="BOB">
>           <CUSTOMER CODE="1">ACME</CUSTOMER>
>           <CUSTOMER CODE="2">BLAMMO</CUSTOMER>
>      </SALESPERSON>
>      <SALESPERSON NAME="TODD">
>           <CUSTOMER CODE="1">ACME</CUSTOMER>
>           <CUSTOMER CODE="3">KABLOOEY</CUSTOMER>
>      </SALESPERSON>
>      <SALESPERSON NAME="BETTY">
>           <CUSTOMER CODE="4">JUICY JUICY</CUSTOMER>
>           <CUSTOMER CODE="2">BLAMMO</CUSTOMER>
>      </SALESPERSON>
> </SALESFORCE>
