Returns the parent of an XML element.

fxml_getParent(xmlflat.df, elemid)



A flat XML dataframe created with fxml_importXMLFlat.


The ID of the XML element. The ID is the value of the elemid. field in the flat XML dataframe.


The ID (xmlflat.df$elemid.) of the parent node of the XML element with ID elemid. If no parent exists (because XML node elemid is the root node of the XML document) then NULL is returned.
