public class NodeNameFunctionIterator extends LocalFunctionCallIterator
Implementation of the fn:name function according to XQuery 3.1 specification. Returns the name of a node, as an xs:string that is either the zero-length string, or has the lexical form of an xs:QName. Function signatures: - fn:name() as xs:string - fn:name($arg as node()?) as xs:string 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 zero-length string - If the node identified by $arg has no name (that is, if it is a document node, a comment, a text node, or a namespace node having no name), the function returns the zero-length string - Otherwise, the function returns the value of the expression fn:string(fn:node-name($arg))
