I'm using the NIFI ExtractText Processor and I'm trying to come up with the regular expression to extract a Header and its value from a JSON String. Sample JSON Data is: {"_id": "5b42fe8f7f663540330b3bdc","index": 0,"guid": "60358c95-e50c-4f5e-ad48-00d9e1f9a849","isActive": true,"balance": "$2,483.56","picture": "http://placehold.it/32x32","age": 32,"eyeColor": "green"} I want to extract only the Header (eyecolor) and its value (green), ID field(ID) and its value (5b42fe8f7f663540330b3bdc). What would be a valid regular expression to get this value? Thanks! ... View more
