Importing json or XML into XMIND

Has anyone figured out how to do this?

Basically, I’m working on bug bounties. I’m working on a script that consolidates Harvester and dnsrecon data into a single XML file to import into XMIND.

Here’s the problem, XMIND doesn’t accept XML files in their current state. I’ve tried the suggestions here, but to no avail.

Has anyone had any luck with this? If so please share. I’m open to any other suggestions.
