I am trying to pull the URI of the currently playing track on a sonos speaker and then use that elsewhere. I am able to pull all of the track data and store that in a variable, but it is more text than just the URI itself. Is there a way to get a substring of the variable text I stored?

It ends up setting currentTrack to “{“station”:“RINCON\_5CAAFDA596E801400”,“name”:null,“artist”:null,“album”:null,“trackNumber”:“1”,“status”:“playing”,“level”:”",“uri”:“x-sonos-htastream:RINCON\_5CAAFDA596E801400:spdif”,“trackUri”:“x-sonos-htastream:RINCON\_5CAAFDA596E801400:spdif”,“transportUri”:“x-sonos-htastream:RINCON\_5CAAFDA596E801400:spdif”,“enqueuedUri”:"",“metaData”:“RINCON\_5CAAFDA596E801400\<\u002fdc:title\>object.item.audioItem\<\u002fupnp:class\>x-sonos-htastream:RINCON\_5CAAFDA596E801400:spdif\<\u002fres\>\<\u002fitem\>\<\u002fDIDL-Lite\>”,“trackMetaData”:“x-sonos-htastream:RINCON\_5CAAFDA596E801400:spdif\<\u002fres\>\<\u002fr:audioInputIcon\>21\<\u002fr:streamInfo\> \<\u002fdc:title\>object.item\<\u002fupnp:class\>\<\u002fitem\>\<\u002fDIDL-Lite\>”}"
