Notes

This stores nested GML attributes as dictionaries in the NetworkX graph, node, and edge attribute structures.

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 writing int/float/str/dict/list data as required by the GML specification. For writing other data types, and for reading data other than str you need to explicitly supply a stringizer/destringizer.

For additional documentation on the GML file format, please see the GML url.

See the module docstring networkx.readwrite.gml for more details.
