<country id='fr' name='France'  pop='60000000'/>
<region id='Asia'>
<country id='cn' name='China' pop='1300000000'/>

The XPath expression //country[@id='fr']/@pop find the country node that has attribute id set to 'fr', it returns the value of the pop attribute.

The value returned should be 60 million.
