Here is a sample JSONArray in which I am trying to search using JsonPath:

["ح م د","ر ب ب","ع ل م","ر ح م","م ل ک","ی و م","د ی ن","ع ب د","ع ون","ع ون","س ف ہ","س ف ہ"]

Its an array of Arabic characters. I am trying to search for value that begins with specific character, for eg. س (seen)

I am using JsonPath like this:

JsonPath.read(myJSONArray.toString(), "$[*][?(@ =~ /^س/i)]", null);

Its returning 0, whereas it should return 2 values as per the sample data. Any idea why the expression not working?

Note: My actual JSONArray includes records in 1000s. So if you think there is better approach than to use JsonPath java library, then your suggestion are most welcome. :)

have you verified your regex? maybe use an external regex-checker? – Martin Frank Sep 27 '16 at 12:28
@MartinFrank I have tried on regex101.com without using ^ and its working but in Java its still returning 0 – codelearner Sep 27 '16 at 12:35
I am in doubt in XPath expression but the documentation at https://github.com/jayway/JsonPath is for JSONObject with Array, mine is simple JSONArray. – codelearner Sep 27 '16 at 12:38
you have to add unicode encoding while searching arabic . See http://stackoverflow.com/a/15203555/3496570 – Zar E Ahmer Sep 28 '16 at 07:15
I have further experimented on XPath Java library and it seems to only work with JSONObjects, simple JSONArray doesn't support regex. – codelearner Sep 28 '16 at 09:33
