Location Steps

• A location step has three parts:

  • The axis

  • The node test

  • An optional predicate

• axis::node-test[predicate]

• child::PERSON[position()=2]

• The axis tells you in what direction to search from the context node.

• The node test tells you which nodes to consider along the axis.

• The predicate is a boolean expression that tests each node in that set. If that expression returns false, then the node is removed from the set.
