hmmm, a key for sorting these values i suspect ?

look at www.dpawson.co.uk XSL faq area on keys for this...

u need to put the current node test first

but in any event the following should be illustrative of how one would get
the right test ( i've used a for-each, but of course u could use templates )

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

<xsl:template match="root">
   <xsl:for-each select="//Billcode">

   <xsl:value-of select="@country='USA'"/>

   </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

xml file
----------------------------------------------------
<?xml version="1.0" ?>
<root>
<Billcode corp="EvilEmpire" country="USA"/>
<Billcode corp="FunEmpire" country="UK"/>
<Billcode corp="SunEmpire" country="BERMUDA"/>
</root>

HTH, in the future i would include a slightly more defined example of 'what
u want to do' maybe in the form of desired results, also pls quote your XSLT
processor,
