write_gexf

write_gexf(G, path, encoding='utf-8', prettyprint=True, version='1.1draft')

Write G in GEXF format to path.

“GEXF (Graph Exchange XML Format) is a language for describing complex networks structures, their associated data and dynamics” [R249].

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.

Notes

This implementation does not support mixed graphs (directed and unidirected edges together).

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.
