      Parameters
      ----------
      G : graph
         A networkx graph
      path : file or string
         File or filename to write.
         Filenames ending in .gz or .bz2 will be compressed.
      encoding : string (optional)
         Encoding for text data.
      prettyprint : bool (optional)
         If True use line breaks and indenting in output XML.
      infer_numeric_types : boolean
         Determine if numeric types should be generalized.
         For example, if edges have both int and float 'weight' attributes,
         we infer in GraphML that both are floats.
      named_key_ids : bool (optional)
         If True use attr.name as value for key elements' id attribute.
      edge_id_from_attribute : dict key (optional)
          If provided, the graphml edge id is set by looking up the corresponding
          edge data attribute keyed by this parameter. If `None` or the key does not exist in edge data,
          the edge id is set by the edge key if `G` is a MultiGraph, else the edge id is left unset.
  
      Examples
      --------
      >>> G = nx.path_graph(4)
      >>> nx.write_graphml(G, "test.graphml")
  
      Notes
      -----
      This implementation does not support mixed graphs (directed
      and unidirected edges together) hyperedges, nested graphs, or ports.
