    copied!<p>I'm working with twitter's api, trying to get the json data from</p> <pre><code>http://search.twitter.com/trends/current.json </code></pre> <p>which looks like:</p> <pre><code>{"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} </code></pre> <p>My structs look like: </p> <pre><code>type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } </code></pre> <p>and then I parse the JSON into a variable of type <code>Trending</code>. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data.</p> <p>I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)</p> <p>UPDATE: In accordance with PeterSO's comment I'm going the regexp route. Using:</p> <pre><code>Cur_Trends := new(Current) /* unmarshal the JSON into our structures */ //find proper json time-name aoUnixTime, _, _ := os.Time() // insert code to find and convert as_of Unix time to aoUnixTime aoName := time.SecondsToUTC(aoUnixTime).Format(`"2006-01-02"`) fmt.Printf("%s\n", aoName) regexp_pattern := "/" + aoName + "/" regex, _ := regexp.Compile(regexp_pattern); cleaned_json := regex.ReplaceAllString(string(body2), "ntrends") os.Stdout.WriteString(cleaned_json) </code></pre> <p>Doesn't show any changes. Am I specifying the regexp wrong? It seems like 'Go' only allows for one regexp at a time...</p> <p>UPDATE: can now change the date/time to "ntrends" but the "Unmarshaling" isn't working. I can get everything moved into an interface using json.Decode, but can't iterate through it...</p> <p>I guess my new question is, How do I iterate through: </p> <pre><code>map[as_of:1.268176902e+09 trends:map[ntrends:[map[name:#nowplaying query:#nowplaying] map[name:#imtiredofseeing query:#imtiredofseeing] map[name:#iWillNever query:#iWillNever] map[name:#inmyfamily query:#inmyfamily] map[name:#raiseyourhandif query:#raiseyourhandif] map[name:#ripbig query:#ripbig] map[name:QVC query:QVC] map[name:#nooffense query:#nooffense] map[name:#RIPLaylaGrace query:#RIPLaylaGrace] map[name:Justin Bieber query:"Justin Bieber"]]]] </code></pre> <p>using "for...range" is giving me weird stuff...</p>
