XML and IEnumerator problems on webgl

When i switch to WebGL platform i get script error on my XML lang script that does work for other platform.

Code (JavaScript):

1.     public function setLanguage ( path : String, language : String) {
2.         var xml : XmlDocument = new XmlDocument();
3.         xml.Load(path);
4.        
5.         Strings = new Hashtable();
6.         var element : XmlElement = xml.DocumentElement.Item[language];
7.         if (element) {
8.             var elemEnum : IEnumerator = element.GetEnumerator();
9.             while (elemEnum.MoveNext()) {
10.                 Strings.Add(elemEnum.Current.GetAttribute("name"), elemEnum.Current.InnerText);
11.             }
12.         } else {
13.             Debug.LogError("The specified language does not exist: " + language);
14.         }
15.     }

The errors are

BCE0019: 'InnerText' is not a member of 'Object'.
BCE0019: 'GetAttribute' is not a member of 'Object'.

I have no idea if its something not implemented yet, or a limitation on webgl, it does work on webplayer.

 

Thank you, casting it as XmlElement worked, it was kinda confusing because it worked ok whiout that for webplayer and windows, and it was my only script to have a issue with webgl.
