You haven't told us what processor you're using, nor what language 
you're doing this work in.

I just wrote the following XSLT to test it:

<?xml version="1.0"?>
<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01"
   xmlns:curr="http://www.ecb.int/vocabulary/2002-08-01/eurofxref"
   version="1.0">

   <xsl:output method="html"/>

   <xsl:template match="/">
     <html>
       <head>
         <title>Euros to Dollars</title>
       </head>
       <body>
         <p>
           <xsl:text>Today the Euro is worth </xsl:text>
           <xsl:apply-templates
             select="gesmes:Envelope/curr:Cube/curr:Cube
                     /curr:Cube[@currency='USD']/@rate"/>
           <xsl:text> US Dollars</xsl:text>
         </p>
       </body>
     </html>
   </xsl:template>

</xsl:stylesheet>

You can see this execute in Cocoon at http://publish.ucc.ie/feeds/currency
