Hi Marc and Gerard, Just to let you know that I'm still working on this. At the moment the code only exports the nodes, I'll start working on processing the child relations now. To run this, it's necessary to install the scripting plugin and download Jython. Then select scripting/show scripting console and copy/paste this code to the editor window and save it. Then select a collection relation and press the Run button. The result goes to C:/export.gpx. You probably want to change that when running on Linux.
