Regexp, can't match many elements contained in an array (json) - ruby

Question

I have trouble doing a regexp, and I don't know how to formulate the questions, so better than words, here is an example
String
"medias": [
{
"height": 800,
"id": "",
"origin": "google",
"thumbnail": {
"height": 94,
"url": "https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTF_KeDfHAxLuvCoYkuKUcwPKpxHfjt19g-E0uhsV20rLGf6VbJ--NFKCuO",
"width": 150
},
"title": "144779-cat-cats.jpg",
"type": "image",
"url": "https://lh4.googleusercontent.com/-bemqYIv9dPw/UTsFD0yJsBI/AAAAAAAAAZI/1zrKmdolPLY/s0-d/144779-cat-cats.jpg",
"width": 1280
},
{
"height": 300,
"id": "",
"origin": "google",
"thumbnail": {
"height": 94,
"url": "https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcR60TwME2D02rjeROsOlHSMdk5AkrtwPwJIhsXBqoOoISUA95rXpKXihL4",
"width": 124
},
"title": "cats-in-sink.jpeg",
"type": "image",
"url": "https://lh4.googleusercontent.com/-zrZJg2qJQlI/Tg9kwdqbsrI/AAAAAAAAAEQ/Oal8KLLfItk/cats-in-sink.jpeg",
"width": 397
}
]
Regexp
"medias": \[
([{
"height": \d+[,|]
"id": ".*"[,|]
"origin": ".*"[,|]
"thumbnail": {
"height": \d+[,|]
"url": ".*"[,|]
"width": \d+[,|]
}[,|]
"title": ".*"[,|]
"type": ".*"[,|]
"url": ".*"[,|]
"width": \d+[,|]
}[,|]]*)[,|]
\][,|]
Just the middle part of the regexp, between (), works fine. but when I add the media wrapper around it gets broken.
"medias": \[
....................
....................
...........[,|]
\][,|]
Here you'll find the middle part matching
And here you'll find the complete regexp that is broken
Any Idea ?

Use the function json_decode() in php instead
$array = json_decode($json_object);
