java - Getting string in side curly braces that also has more values in curly braces within it -


so here's (java) string 

string s = "some string preceding {\"key1\": \"val1\", \"key2\": {\"embedkey1\": \"embedval1\", \"embedkey2\": \"embedval2\"}, \"key3\" : \"val3\", \"key3\": \"val4\"}, value proceeding it"

i want within outer curly braces. how do that? far i've tried following

    pattern p = pattern.compile("\\{([^}]*)\\}");     matcher m = p.matcher(s);     while(m.find()){        system.out.println(m.group(1));     }

this however, prints 

"key1": "val1", "key2": {"embedkey1": "embedval1", "embedkey2": "embedval2"

can please me this?

to in between outer braces, or between first { , last }, use greedy matching . matching symbols (with dotall mode):

string s = "some string preceding {\"key1\": \"val1\", \"key2\": {\"embedkey1\": \"embedval1\", \"embedkey2\": \"embedval2\"}, \"key3\" : \"val3\", \"key3\": \"val4\"}, value proceeding it"; pattern p = pattern.compile("(?s)\\{(.*)}"); matcher m = p.matcher(s); while(m.find()){     system.out.println(m.group(1)); }

see ideone demo

the (?s) inline version of pattern.dotall modifier.
