public class NodeQNameFunctionIterator extends LocalFunctionCallIterator
Implementation of the fn:node-name function according to XPath and XQuery Functions and Operators 3.1 (https://www.w3.org/TR/xpath-functions-31/#func-node-name) and the XDM 3.1 node-name accessor. XDM 3.1 Section 5.10 node-name Accessor. dm:node-name($n as node()) as xs:QName? "The dm:node-name accessor returns the name of the node as an xs:QName, or the empty sequence if the node does not have a name." Function signatures (Functions and Operators 3.1, fn:node-name):
  • fn:node-name() as xs:QName?
  • fn:node-name($arg as node()?) as xs:QName?
Rules:
  • "If the argument is omitted, it defaults to the context item."
  • "If the argument is supplied and is the empty sequence, the function returns the empty sequence."
  • "Otherwise, the function returns the result of applying the dm:node-name accessor to the node identified by the argument. If the dm:node-name accessor returns the empty sequence, then the function returns the empty sequence."
The optional xs:QName result wraps the expanded Name from Item.nodeName() in a QNameItem; otherwise the function returns the empty sequence.
