I have the following XML:-

<doc>
  <animal value="Dog">
    <type value="Mammal Canine" />
    <legs value="4" />
  </animal>
  <animal value="Cat">
    <type value="Mammal Feline" />
    <legs value="4" />
  </animal>
  <animal value="Tasmainian Devil">
    <type value="Mammal Marsupial" />
    <legs value="4" />
  </animal>
</doc>

How do I select all 'Animal' nodes that have a 'type' node with an attribute value that contains 'Mammal'?

Try out something linke this: /doc/animal[contains(./type/@value,'Mammal')]

Thank you. That works perfectly.
