"""Read graph in GEXF format from path.
"GEXF (Graph Exchange XML Format) is a language for describing
complex networks structures, their associated data and dynamics" [1]_.
Parameters
----------
path : file or string
File or filename to write.
Filenames ending in .gz or .bz2 will be compressed.
node_type: Python type (default: str)
Convert node ids to this type
relabel : bool (default: False)
If True relabel the nodes to use the GEXF node "label" attribute
instead of the node "id" attribute as the NetworkX node label.
Returns
-------
graph: NetworkX graph
If no parallel edges are found a Graph or DiGraph is returned.
Otherwise a MultiGraph or MultiDiGraph is returned.
Notes
-----
This implementation does not support mixed graphs (directed and unidirected
edges together).

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.

>>> nx.write_gexf(G, "test.gexf")

The node id attribute is set to be the string of the node label.
If you want to specify an id use set it as node data, e.g.
node['a']['id']=1 to set the id of node 'a' to 1.
