I want to replace dot and single apostrophe characters within a JSON string, ie only when quoted. Using this input:
String json = "{\"someJsonMap\":{\"with.dot.s\":1.0,\"'with.dots'.and.apostroph's.\":20.001}}";
I want to turn this:
{"someJsonMap":{"with.dot.s":1.0,"with.dots'.and.apostroph's":20.001}}
into this:
{"someJsonMap":{"withdots":1.0,"withdotsandapostrophs":20.001}}
I appreciate any help, solutions or explanations.
If there are never escaped quotes, then you use a look ahead for an odd number of quotes that follow. An odd number means you are inside quotes.
json = json.replaceAll("['.](?=(([^\"]*\"){2})*[^\"]*\"[^\"]*$)", "");
That trainwreck of a regex asserts that there's an odd number of quotes following by consuming multiples (0-n via *) of pairs of quotes ([^\"]*\"){2} with the remaining chars having only one quote [^\"]*\"[^\"]*$
If there are escaped quotes, you basically can't use regex.
