  <pre><code>XmlDocument findStringDoc = new XmlDocument();
      findStringDoc.Load (Application.dataPath+ "/" + filename);
      XmlNodeList nodeList = findStringDoc.SelectNodes("/results/error");
      //XmlNodeList suggestionNodeList = findStringDoc.SelectNodes("/results/error/suggestions/option");
      foreach(XmlNode xn in nodeList){
          errorString.Add(xn["string"].InnerText);
          errorType.Add(xn["type"].InnerText);
          //string temp = xn["suggestion"].InnerXml;
  
          ////TODO: Retrieve suggestions here!
          XmlNodeList suggestionNodeList = findStringDoc.SelectNodes("/suggestions");
          foreach(XmlNode yn in suggestionNodeList){
              option[suggestionNodeList.Count] = yn["option"].InnerText;
              Debug.Log(yn["option"].InnerText);
          }
          suggestionResult.Add (option);
          //Debug.Log(suggestionResult);
  
          //XmlNodeList suggestionNodeList = findStringDoc.SelectNodes("/results/error[string='{0}']/suggestions/option",errorString[i]);
      }
