Returns the expanded QName of $node-var. An expanded QName contains a namespace URI and a local name.
If the value of $node-var is the empty sequence, the following error message is displayed:
Error occurred while executing XQuery: Error loading the XQuery or XSLT for this method: Type error in function node-name invocation: expected type node, given type empty
The empty sequence is a sequence containing zero items (), which is similar to null in SQL.
If a $node-var is not a node, the following error is displayed in the mapper:
Error occurred while executing XQuery: Error loading the XQuery or XSLT for this method: Type error in function node-name invocation: expected type node, given type [string@http://www.w3.org/2001/XMLSchema]
xf:node-name(xf:node $node-var) —> xs:QName?
Returns the expanded QName of $node-var. An expanded QName contains a namespace URI and a local name.
Returns the empty sequence for nodes that do not have names (document, text, processing-instruction, comment). The empty sequence is a sequence containing zero items (), which is similar to null in SQL.
When you invoke the following query:
let $x := <elem xmlns:foo="http://www.acme.org/"><foo:subelem/></elem>, $name := xf:node-name(children($x)) return <result> <uri> { xf:get-namespace-from-QName($name) }</uri> <local>{ xf:get-local-name-from-QName($name) }</local> </result>
The preceding query generates the following result:
<?xml version="1.0" encoding="UTF-8"?>
<result>
<uri>http://www.acme.org/</uri>
<local>subelem</local>
</result>
