In order to convert a GEXF (Graph Exchange XML Format) file to the nodes and edges CSV files, you can use the command:

python main.py {yourFileName}.gexf

This file has two columns: nodeID and nodeName.

This file has three columns: SourceID, TargetID and weight.

SourceID and TargetID represents the id of the source and target nodes. weight represents the weight of the edge.

If the graph is undirected (has attribute defaultedgetype as undirected in the GEXF file), the edges CSV file will contain two edge rows for each edge specified in the GEXF file.
