I've a string like:

{\"clearExistingTargeting\":\"Yes\",\"campaignid\":\"[CampaignID]\",\"targeting\":{\"appsitetargeting\":{\"[filterout]\":{\"site\":\"www.google.com\",\"app\":\"com.facebook\"},\"filterin\":{\"site\":\"www.gmail.com\",\"app\":\"com.lw.sdk\"}}}}

I want to extract all those string which are enclosed in [] like [CampaignID] and [filterout], I am trying with regular expression - (\\[.*\\]) but its giving the output

[CampaignID]\",\"targeting\":{\"appsitetargeting\":{\"[filterout]

Its matching from the first [ but ending with the last ].

make it lazy using :- `(\\[.*?\\])` or `([^]]*)` – rock321987 Jul 06 '16 at 07:35
@rock321987 Output is: {"clearExistingTargeting":"Yes","campaignid":"[CampaignID ","targeting":{"appsitetargeting":{"[filterout ":{"site":"www.google.com","app":"com.facebook"},"filterin":{"site":"www.gmail.com","app":"com.lw.sdk"}}}} – Pankaj Kumar Katiyar Jul 06 '16 at 07:39

@rock321987 worked with (\\[.*?\\]) Thanks a lot – Pankaj Kumar Katiyar Jul 06 '16 at 07:40
