MarkLogic 9 Product Documentationxdmp:QName-from-key
xdmp:QName-from-key( $key as xs:string ) as xs:QName
Summary
Construct a QName from a string of the form "{namespaceURI}localname". This function is useful for constructing Clark notation parameters for the xdmp:xslt-eval and xdmp:xslt-invoke functions.
| Parameters | |
|---|---|
| key | The string from which to construct a QName. |
Example
(: Using a key based on a QName with an in-scope namespace prefix :)
xquery version "1.0-ml";
let $key := xdmp:key-from-QName(xs:QName("xs:string"))
let $qname := xdmp:QName-from-key($key)
return ($key, $qname)
(: Returns output of the following form:
( {http://www.w3.org/2001/XMLSchema}string, xs:string )
The generated QName uses the "xs" namespace prefix because
this binding is implicitly defined in MarkLogic.
:)
Example
(: Using a key based on an arbitrary namespace :)
xquery version "1.0-ml";
xdmp:QName-from-key("{/my/namespace}thing")
(: Returns output of the following form:
thing
:)
