how to submit the text in wysiwyg mode?

after i searched the forum, the solution couldn't be found. so i have to post for answer.

1. i use the code to sumbit

 ckEditor.on("instanceReady",function()
                {                
                  // overwrite the default save function
                  ckEditor.addCommand( "save", {
                    modes : { wysiwyg:1, source:1 },
                    exec : function () {                
                      // get the editor content
                      var theData = ckEditor.getData();
                      alert(theData);
                    }
                    })
                }); 

but it sumbit the raw code of the text which i typed, translated from < to &lt; , i just want to submit the content in the wysiwyg mode, and i changed the code above from source:1 to source:0 , it doesn't effect.

2. i want to use the editor to generate the XML file, is it a shortcut to create it? such as using the API CKEDITOR.dom etc.

Thanks a lot!
