string

The string() function converts its argument to a string. When the argument is a node, it extracts the string value of the node; when the argument is an atomic value, it converts the atomic value to a string in a similar way to the xs:string() constructor function.

For example, the expression «string(4.00) » returns the string "4" .

Argument	Data Type	Meaning
