string

The string function in XQuery is used to convert an argument to its string representation. It is commonly used to ensure that a given value is treated as a string.

Syntax

fn:string(arg)

The following table describes the argument for this command:

Argument	Required/Optional	Description
arg	Required	The item you want to convert to a string. This can be any atomic type, node, or sequence. The sequences with more than one item will return an error.

Return Value

Returns the value of

$arg

represented as a

xs:string

. If no argument is supplied, the context item (

) is used as the default argument. The behavior of the function if the argument is omitted exactly the same as if the context item had been passed as the argument.
