# Load example file with population data from United Nations Statistics Division # and create flat dataframe example <- system.file("worldpopulation.xml", package="flatxml") xml.dataframe <- fxml_importXMLFlat(example) # Determine the number of siblings (elements on the same hierarchy level) of the XML element # with ID 4 (xml.dataframe$elemid. == 4) fxml_numSiblings(xml.dataframe, 4)
#> [1] 4
