XPath Operators

All operators defined by XPath are listed here.

Mathematical Operators

+ (plus)

Adds one number to another

- (minus)

Subtracts one number from another

* (multiplication)

Multiplies one number by another

div

Performs a floating-point division between two numbers

mod

Returns the floating-point remainder of dividing one number by another

Boolean Operators

=

Tests whether two expressions are equal.

<

Tests whether the first expression is less than the second. Within an attribute, this operator must be coded <.

<=

Tests whether the first expression is less than or equal to the second. Within an attribute, this operator must be coded <=.

>

Tests whether the first expression is greater than the second. Within an attribute, this operator can be coded >.

>=

Tests whether the first expression is greater than or equal to the second. Within an attribute, this operator can be coded >=.

!=

Tests whether the two expressions are not equal.

and

Tests whether both the first and second expressions are true. If the first expression is false, the second is not evaluated.

or

Tests whether either the first or second expressions are true. If the first expression is true, the second is not evaluated.

Comparing values of various datatypes

For the first six boolean operators, comparing values of various datatypes is complicated. We explain the various possibilities here:

If both objects are boolean values

Then they are equal if they have the same value. For less-than and greater-than ...
