Question on Parsing a String in a CML Macro - kblagron - 06-18-2019

I am playing with the Native Echo Smarthome Skill, and had a question on the best way to do this.

I have┬áthe following text string:┬á "{'channel': {'number': '100'}, 'channelMetadata': {}}"

I want to save the number shown (100) into a variable┬áand discard the rest.┬á What would be the best recommended way to do so in a CML Macro?┬á I know I can do some splits,┬ástrips, and indexes┬áand get to it in 4 ┬áor 5 commands, but was curious is there an easier way to capture that?┬á The Starting point will always be the same, but the number could be 1, 2, or 3 digits long.

My first stab at this was as follows:

┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á DataParm.Cut(0,24);
┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á ┬á DataParm.Split(TmpStr,''',False);

I guess that should suffice, but open for other ideas.

That's just JSON, so use the JSON parser and it'll do all of that for you.
