A location path consists of an axis, a node test, and optionally, one or more predicates. In this article I explain the predicate term used in Axes. The syntax is as follow,

AxisName :: Node_Test [predicates]

Hear predicate is optional term. In my previous article I will explain the Name of axis and the Node Test now in this we see the predicate.

An XPath predicate allows us to write very specific rules about the nodes that we like to select when making our expressions. There are different types of expressions that we can use in your predicates. Some of them are:

  • Node Set
  • Boolean
  • Number
  • String
  • Result tree fragment
