How to cut a string with a regular expression?

Question

Java

Good afternoon! There is a line
String valueUrl = getPage(" api.vk.com/method/database.getRegions?&country_id=1 ");
the cat contains the answer:

{"response":[{"region_id":"1000001","title":"Адыгея"},{"region_id":"1121540","title":"Алтай"},{"region_id":"1121829","title":"Алтайский край"},{"region_id":"1123488","title":"Амурская область"},{"region_id":"1000236","title":"Архангельская область"},

"It repeats so ad infinitum =) "
How to cut it with a regular expression so that there are only regions (and put them in an array)?
String[] urlRegexp = valueUrl.split(" ??? "); --- I do not understand what to prescribe here so that everything turns out as intended?
I tried , it worked for me, but with the id number and ":" , "," .

Answer 1

If you really want a regular expression, then you can do something like:

String s = "та самая строка";
// коды
Matcher m = Pattern.compile("\"region_id\":\"(\\d+)\"").matcher(s);
while (m.find()) { m.group(1));}

// названия
Matcher m2 = Pattern.compile("\"title\":\"([^\"]+)\"").matcher(s);
while (m2.find()) { m2.group(1));}

You receive data in JSON format. use any JSON reader for your PL and it will be much easier.
