codepoint-equal

The codepoint-equal function in XQuery is used to compare two strings to determine if they are equal based on their Unicode code points. It checks if two strings are identical without considering any advanced collation rules.

Syntax

fn:codepoint-equal(comparand1, comparand2)

The following table describes the argument for this command:

Argument	Required/Optional	Description
comparand1	Required	The first string to compare. It can be an actual string or an empty sequence ( () ).
comparand2	Required	The second string to compare. It can also be an actual string or an empty sequence ( () ).

Return Value

Boolean.

Returns

true

false

depending on whether the value of

$comparand1

is equal to the value of

$comparand2

, according to the Unicode code point collation.

Returns an empty sequence if either input is an empty sequence.

Examples

The following table lists some sample values and return values:

SAMPLE FUNCTION	OUTPUT
fn:codepoint-equal('abc', 'abc')	true
fn:codepoint-equal('abc', 'ab c')	false
fn:codepoint-equal('abc', ())	()
fn:codepoint-equal((), ())	()
fn:codepoint-equal("hello", "world")	false
fn:codepoint-equal("hello", "")	false
