Need help with Strings

Okay, so I need to get only a specific part of a String, but I need to blank out a small amount of it.

Here's what I need to cut apart:

Code:

[{"broadcast_part": 1, "featured": true, "channel_subscription": false, "audio_codec": "uncompressed", "id": "5708525952", "category": "gaming", "title": "\u4e9e\u6d32\u7d71\u795e \u54ad\u54ad\u4e09\u6bd4\u9748 -  \u9738\u6c23\u56de\u6b78  Gragas God :: TW rank Diamond", "geo": "TW", "video_height": 960, "site_count": 4509, "embed_enabled": false, "channel": {"subcategory": null, "producer": true, "image_url_huge": "http://www-cdn.jtvnw.net/static/images/404_user_600x600.png", "timezone": "", "screen_cap_url_huge": "http://static-cdn.jtvnw.net/previews/live_user_asiagodtonegg3be0-630x473.jpg", "id": "5708525952", "views_count": 1428767, "category": "gaming", "embed_code": "<object type=\"application/x-shockwave-flash\" data=\"http://www.justin.tv/widgets/live_embed_player.swf?channel=asiagodtonegg3be0\" id=\"live_embed_player_flash\" height=\"300\" width=\"400\" bgcolor=\"#000000\"><param name=\"allowFullScreen\" value=\"true\"/><param name=\"allowScriptAccess\" value=\"always\" /><param name=\"allowNetworking\" value=\"all\" /><param name=\"movie\" value=\"http://www.justin.tv/widgets/live_embed_player.swf\" /><param name=\"flashvars\" value=\"hostname=www.justin.tv&channel=asiagodtonegg3be0&auto_play=false&start_volume=25\" /></object><a href=\"http://www.justin.tv/asiagodtonegg3be0#r=-rid-&amp;s=em\" class=\"trk\" style=\"padding:2px 0px 4px; display:block; width:345px; font-weight:normal; font-size:10px; text-decoration:underline; text-align:center\">Watch live video from asiagodtonegg3be0 on www.justin.tv</a>", "title": "asiagodtonegg3be0", "image_url_tiny": "http://www-cdn.jtvnw.net/static/images/404_user_50x50.png", "screen_cap_url_large": "http://static-cdn.jtvnw.net/previews/live_user_asiagodtonegg3be0-320x240.jpg", "channel_url": "http://www.justin.tv/asiagodtonegg3be0", "status": "\u4e9e\u6d32\u7d71\u795e \u54ad\u54ad\u4e09\u6bd4\u9748 -  \u9738\u6c23\u56de\u6b78  Gragas God :: TW rank Diamond", "meta_game": "League of Legends", "tags": null, "image_url_small": "http://www-cdn.jtvnw.net/static/images/404_user_70x70.png", "screen_cap_url_medium": "http://static-cdn.jtvnw.net/previews/live_user_asiagodtonegg3be0-150x113.jpg", "language": "en", "embed_enabled": false, "subcategory_title": "", "image_url_medium": "http://www-cdn.jtvnw.net/static/images/404_user_150x150.png", "image_url_large": "http://www-cdn.jtvnw.net/static/images/404_user_300x300.png", "mature": null, "screen_cap_url_small": "http://static-cdn.jtvnw.net/previews/live_user_asiagodtonegg3be0-70x53.jpg", "login": "asiagodtonegg3be0", "category_title": "Gaming"}, "up_time": "Mon May 20 03:21:34 2013", "meta_game": "League of Legends", "format": "live", "channel_count": 6142, "embed_count": 1176, "abuse_reported": false, "video_width": 1280, "stream_type": "live", "name": "live_user_asiagodtonegg3be0", "language": "en", "stream_count": 5685, "video_bitrate": 261.5703125, "broadcaster": "obs", "video_codec": "AVC", "channel_view_count": 1432775}]

Now, that's twitch's api. I need to get a tiny part of it:

Code:

 "channel_count": 6142

So I thought, okay, they've got these commas, so i'll split them into a String array, and tried doing this:

Code:

        String[] arrayData = data.dataToString().split(",");
        String channel_count = arrayData[41];
        channel_count = channel_count.replaceAll("\"channel_count\":", "");
        viewers = Integer.valueOf(channel_count);

Turns out, it's not always 41st in the data, it changes the list size, and very fast. Any ideas?

You could try using indexes, but one way you could make it so that you could get any data:

Code:

Map<String, String> dataMap = new HashMap<String, String>();
String[] split = data.dataToString().split(", ");
for(String info: split){
  String[] infoSplit = info.split(": ");
  dataMap.put(infoSplit[0], infoSplit[1]);
}

Then to get it:

Code:

String channel_count = dataMap.get("\"channel_count\"");

 

Regex FTW: channel_count":\s+?\d+
