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 handlingint
/float
/str
/dict
/list
data as required by the GML specification. For other data types, you need to explicitly supply astringizer
/destringizer
.For additional documentation on the GML file format, please see the GML url.
