My code is working fine in FireFox but my users are restricted to IE. I'm getting an error though in IE, related to my JQUERY function.

 populateTable:function(returnList) {


     var self = this;
     var eat = $.evalJSON(returnList.firstChild.textContent)
     $.each(eat,function() {


$("<tr><td>" + this.reportId + "</td><td>" + this.description + "</td><td>" + 
this.drawingNumber + "<td></tr>").insertAfter(self.tblResults[0].childNodes[1]);

 })


}

IE is erring on the $.each with the message below:

'Length' is null or not an object

Any ideas or maybe a workaround for the $.each function?

Update: returnList is an XML document object from an Ajax call. I'm trying to retrieve the JSON object string located within the XML tag.
