title: Ho to convert an xml file to map[string]interface{} in golang?
body: <p>I know the method <code>Unmarshal</code> in <code>encoding/json</code> can convert a json to <code>map[string]interface{}</code>, so I also want to do same thing with <code>encoding/xml</code>, but it failed.</p>
  
  <p>It seems <code>encoding/xml</code> do not have the similar method, do any one know how to solve it? I don't want to define struct for the xml content, since the xml is generated by many different services.</p>
  
  <p>Thanks in advance.</p>
