Hey,
instead of putting it all in one field, put it in 3 fields for street, city and country. Therefore your can just use a similar rex, but with more capturing groups:
\"lines\":\[\"(?<Street>[^\"]+)\",\"(?<Town>[^\"]+)\",\"(?<Country>[^\"]+)\"
Remember if you use it in Splunk rex, put the " around it. After your rex you got 3 new fields, Street, Town and City. If you want you can use them as they are, or you can use an eval to combine them into one field again:
... | eval adress = 'Town'." ".'City'." ".'Country'
Greetings
Tom
