MarkLogic Server 11.0 Product Documentationfn.nodeName
fn.nodeName( arg as Node? ) as xs.QName?
Summary
Returns an expanded-QName for node kinds that can have names. For other kinds of nodes it returns the empty sequence. If $arg is the empty sequence, the empty sequence is returned.
| Parameters | |
|---|---|
| arg | The node whose name is to be returned. |
Example
var x = fn.head(xdmp.unquote('<hello><goodbye>1</goodbye></hello>'));
fn.nodeName(x.xpath("/child::element()"));
=> hello (because the xdmp.unquote produces a Sequence
containing a document node, and the xpath starts at the
document node and selects the sequence of child elements,
which in this case is the root node named "hello")
