local-name

The local-name function in XQuery returns the local part (local name) of the expanded QName of the node provided as input. This excludes the namespace prefix and namespace URI.

Syntax

fn:local-name(arg)

The following table describes the argument for this command:

Argument	Required/Optional	Description
arg	Optional	The node from which to extract the local name. If omitted or empty, the context item is used.

Return Value

Returns the

xs:string

representing the local name of the input node's QName.

Returns an empty string if the input is an empty sequence or the node does not have a name. For example, text nodes.

Raises an error if no context item is provided and the argument is omitted.

Examples

The following table lists some sample values and return values:

SAMPLE FUNCTION	OUTPUT
fn:local-name(<a:book xmlns:a="http://example.com"/> )	"book"
fn:local-name(text{"Hello"})	""
fn:local-name(())	""
fn:local-name() (with context node <ex:item> in scope)	"item"
