def read_gml(path, label='label', destringizer=None):

    ''''Read graph in GML format from `path`.
    Parameters
    path : filename or filehandle
    The filename or filehandle to read from.
    label : string, optional
    If not None, the parsed nodes will be renamed according to node
    attributes indicated by `label`. Default value: \'label\'.
    destringizer : callable, optional
    A `destringizer` that recovers values stored as strings in GML. If it
    cannot convert a string to a value, a `ValueError` is raised. Default
    value : None.
    Returns
    G : NetworkX graph
    The parsed graph.
    Raises
    NetworkXError
    If the input cannot be parsed.

    Notes
    GML files are stored using a 7-bit ASCII encoding with any extended
    ASCII characters (iso8859-1) appearing as HTML character entities.
    Without specifying a `stringizer`/`destringizer`, the code is capable of
    handling `int`/`float`/`str`/`dict`/`list` data as required by the GML
    specification.  For other data types, you need to explicitly supply a
    `stringizer`/`destringizer`.
    For additional documentation on the GML file format, please see the
    `GML website <http://www.infosun.fim.uni-passau.de/Graphlet/GML/gml-tr.html>`_.
    See the module docstring :mod:`networkx.readwrite.gml` for additional details.
    Examples
    >>> G = nx.path_graph(4)
    >>> nx.write_gml(G, \'test.gml\')
    >>> H = nx.read_gml(\'test.gml\')'
