XPath Syntax Quick Reference

This topic provides a quick reference for XPath expression syntax.

Axes

XPath provides the following axes:

Node Tests

XPath provides the following node tests:

Filters

A filter specifies a constraint on a node set with respect to an axis to produce a new node set.

Location Steps

A location step has the following format:

AxisSpecifier
              ::NodeTest
              [Filter
              ][Filter
              ]...
               

            

XPath Expression

An XPath expression has one of the following formats:

LocationStep[/LocationStep]...
               
FunctionCall()[Filter]/LocationStep[/LocationStep]...
               
(Expression)[Filter]/LocationStep[/LocationStep]...
               

            

A function call or an XPath expression in parentheses can appear only at the very beginning of an XPath expression. An expression in parentheses always returns a node set. Any function that appears at the beginning of an XPath location step expression must return a node set.
