@yuyuyu easiest is to use the xlm2json conversion, then work with the json objects
see https://stackoverflow.com/questions/52281389/convert-xml-to-json-with-nodejs
also, check on the api, it might accept some header to return json instead of xml
@yuyuyu really has nothing to do with MagicMirror… u can do both together
use google search for “use raspberry pi as bluetooth speaker”
lots of different solutions…
