Location Step

• A location step consists of three parts:
  • An axis
  • A node test
  • Zero or more predicates
• Eg, descendant axes, paraelements, and first in the list:

     child::para[position()=1]

• If omitted, the axis is assumed to be the child axis:

     para[position()=1]

• A location step:
  • selects a node set with the node test
  • refines it with the predicates
