A very good news, XMind SDK python is available now! It can help the developers to parse, modify and generate XMind mind maps. Of course, it is useful to build XMind your own extensions.
The SDK is 100% written in python and independent from any Java code of Xmind itself. Actually, we spent more than half a year to complete this SDK. It is now under MIT license and released on GitHub.
For more details, please refer to XMind on GitHub.
