title: basic json > struct question ( using 'Go')
body: <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>
