Extract the relationship from bpmn

I installed camunda plug in at eclipse and now I have to detect and extract the relationships between the diagram elements (sequence flow, message flow, association,…)bpmn whatever the diagram; so i have to use the XML source to do it but i do not even know how to do it.

please help me

Not sure if this is actually a problem with any of bpmn.io tools. Probably you will be able to get help on Camunda forum, so please ask there: https://forum.camunda.org/

ok thank you for your reply
