XPath Operators

This lesson is part of XML · All levels

Summary

XPath provides comparison operators (=,!=, <, >), arithmetic (+, -, *, div, mod), logic (and, or), as well as node merging (). Boolean values can be formed from comparisons and then used on predicates. Note that div is written div because the * mark is already used as a wildcard.

Key points

The comparison operator: =,!=, <, <=, >, >=
Arithmetic operators: +, -, *, div, mod
Logic operator: and as well as or
The sign combines the node-set
Div is used for division instead of slash
