Accessing stringified JSON objects

As another user in my other thread suggested to post another question here in regards to explaining how to access JSON Objects. The code I am using is:

<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script>
$(function () {
    $.getJSON(
       "https://api.guildwars2.com/v1/wvw/matches.json",
        function (data) {
            $("#reply").html(JSON.stringify(data));
            // or work with the data here, already in object format
        });
});
</script>

What I am trying to do with the JSON code, is to search through for a specified world_id and return the match_id. I'm very new to JavaScript so I'm not too sure how to do it, and how to access the stringified data which the code above gives me.

The way I figured how to do this, is to create an array and store each object in it, then loop through and check for a matching id like,

if(obj[i].red_world_id == 'xxxx' || obj[i].blue_world_id == 'xxxx' || obj[i].green_world_id == 'xxxx') {
    return obj[i].wvw_match_id;
}

My only problem is I'm not sure how to set an array as the JSON data.

There is no need to stringify, you could work with the JSON object directly:

function(data) {
    var filteredArray=$.grep(data.wvw_matches, function (item) {
        return (item.red_world_id == 'xxxx' || item.blue_world_id == 'xxxx' || item.green_world_id == 'xxxx');
    });
}

See this page for information on jQuery.grep.

.use this code - 

$(function() {
    $.getJSON("https://api.guildwars2.com/v1/wvw/matches.json", function(
            data) {
        $("#reply").html(JSON.stringify(data));
        // or work with the data here, already in object format
        var result = [];//for if it has many matches
        for ( var i=0;i<data.wvw_matches.length;i++ ) {
            var obj = data.wvw_matches[i];
            if (obj.red_world_id == 'xxxx' || obj.blue_world_id == 'xxxx'
                    || obj.green_world_id == 'xxxx') {
                result.push(obj.wvw_match_id);
            }
        }
    });
});
