    <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>
  <car model="C">
    <id>0004</id>
    <name language="en">name 4</name>
  </car>
</order>

File: Query.xquery

for $prod at $count in doc("Data.xml")//car[@model = ("B", "A")]
return <p>{$count}. {data($prod/name)}</p>
