Most memory efficient way to re format a JSON array in Java -

-

say have json array similar following:

[   {     "title": "this title",     "year": 2013,     "images": {       "image": "http://........jpg",     },     "ratings": {       "thumbsup": 1053,       "thumbsdown": 256     }   },   {     "title": "this title",     "year": 2013,     "images": {       "image": "http://........jpg",     },     "ratings": {       "thumbsup": 1053,       "thumbsdown": 256     }   } ]

and required output json array this:

[       {         "title": "this title",         "images": {           "image": "http://........jpg",         },         "ratings": {           "thumbsup": 1053,         }       },       {         "title": "this title",         "images": {           "image": "http://........jpg",         },         "ratings": {           "thumbsup": 1053,         }       }     ]

iv'e been researching , it's suggested efficient way parse using jackson streaming api. use on paas limited memory, wish keep memory usage bare minimum.

is best way parse json jackson streaming api, , construct new json array @ same time or remove elements somehow?

i did similiar xml once. can have requestor tell fields want back, , have emit those. in case had no control on 3rd party axis xml view, once had view, when asked things if there give pieces interested in. bonus, if marshalling or unmarshalling real java objects json after getting json or xml don't need build part of object graph don't care about.

this svg contains rect overflows svg element: <svg id='svg' width='10' height='10'> <rect x='-10' y='-10' width='30' height='30'/> </svg> chrome 28 , opera 12 return getboundingclientrect() svg element width , height of 10. firefox 23 reports width , height of 30. correct? jsfiddle the relevant spec cssom , delegates svg spec if svg element not "have associated css layout box". haven't found definition of "having associated css layout box", correct result seem hinge on definition, getbbox returns 30x30 rect in browsers. this firefox bug fixed now, fix in firefox nightlies , should make through firefox 33 released on 14 october 2014. see bug 530985 details.
