Answer 1

использование:

var Jsonstring = {title: "Movie", actors: [ 'actor1','actor2']}; 
var movie = $.parseJSON(Jsonstring); 
alert(movie.title); //will alert Movie 
alert(movie.actors[0]) // will alert actor1 

эта функция преобразует вашу строку JSON в объект JavaScript.

Answer 2

Вы можете разобрать его с RegExp:

var str = obj.query.pages[564947].revisions[0]['*'], 
    matches = str.match(/\|\s+(starring)\s+=\s+(.+)\n/), 
    result = matches[1] + ': ' + matches[2].replace(/<br\s+\/>/ig, ', ').replace(/[\[\]]/ig, ''); 

Там будет в переменной результата starring: Will Smith, Bridget Moynahan, Bruce Greenwood, James Cromwell, Chi McBride, Alan Tudyk.
