not sure if related, but some IPS templates have names with โ&โ which could break some XML-based exports (if I remember correctly, label is allergies & intolerances). Is that the template you are exporting?
I can share an app that will convert a Web template to xmind. It is a bit limited by the xmind api that we used and it us actually quite tricky to know exactly how much detail to carry.
Thanks for the reply. I actually managed to convert my template to OPML format (with some help from ChatGPT), which I was then able to import into XMind.
