Thanks for your help. The solution is working in IE but not in the firefox. I wish to get the whole outerhtml in firefox similar to the way it is done in IE.

 

Please suggest.

 

// if firefox
  if(editselection.rangeCount > 0)
  {
    var range=editselection.getRangeAt(0);
    var clonedSelection = range.cloneContents();
    var div = document.createElement('div');
    div.appendChild(clonedSelection);
    ret = div.innerHTML;
  }
