data

The atomic value of a node.

The

fn:data

function takes a sequence of items and returns a sequence of atomic values.

fn:data(arg)

The following table describes the argument:

Argument	Required/ Optional	Description
arg	Required	The items whose typed values are to be returned.

For atomic values, it returns the unchanged value. For nodes, it extracts the typed value of the node.

The following expression returns 123, 456 as the result:

fn:data((123, 456))

Assume that you have the following variable definition:

let $x := <hello>Hello

let $x := <hello>Hello
            <world>World</world>
          </hello>

The expression

fn:data($x)

returns the following result:

Hello World
