    <name language="en">name 1</name>
  </car>
  <car model="B">
    <id>0002</id>
    <name language="en">name 2</name>
  </car>
  <car model="B">
    <id>0003</id>
    <name language="en">name 3</name>
  </car>
</order>

File: Query.xquery

let $prods := doc("Data.xml")//car
for $prod in $prods
where $prod << $prods[@model = $prod/@model][last()]
return $prod
