Problems with reading GraphML files.

[Bill Ford]

I have converted a project so it should input and output GraphML files. I used yEd to create the files. The function in OGDF that reads GraphML files always fails by returning false. I would appreciate any help available. Thanks.

Hello Bill,

it would be helpful if you could post one of the GraphML files which cannot be read.

Maybe it helps to adjust the log level before trying to read the GraphML file, this might produce a helpful warning: `GraphIO::logger.localLogLevel(Logger::Level::Minor);` and `Logger::globalLogLevel(Logger::Level::Minor);`.

Best regards,

Dagobert
