xdmp.keyFromQName( name as xs.QName ) as String
Summary
Construct a context-independent string from a QName. This string is of the form "{namespaceURI}localname" and is suitable for use as a map key.
| Parameters | |
|---|---|
| name | The QName to compute a key for. |
Example
// Using a QName with an in-scope namespace prefix
'use strict';
xdmp.keyFromQName('xs:string');
// Returns output of the following form:
// {http://www.w3.org/2001/XMLSchema}string
//
// The generated key includes the XMLSchema namespace URI because the
// "xs" namespace binding is implicitly defined in MarkLogic.
Example
// Using a key based on an arbitrary namespace
'use strict';
xdmp.keyFromQName(fn.QName('/my/namespace', 'thing'));
// Returns output of the following form:
// {/my/namespace}thing
