web-snippet-052 ( preprocessJSON )

function preprocessJSON(str) {

    return str.replace(/("(\\.|[^"])*"|'(\\.|[^'])*')|(\w+)\s*:/g,
    function(all, string, strDouble, strSingle, jsonLabel) {
        if (jsonLabel) {
            return '"' + jsonLabel + '": ';
        }
        return all;
    });

}

// usage: data = JSON.parse(preprocessJSON(json));
// in case you stumble upon single quoted strings, be sure to use: data.replace(/'/g, '"')
