XML Parsing error in Flex

Question

Hello Experts,
I am passing a XML document form the Java to Flex using Remote Object.  My XML is as follows
<root>
<dept ID="1" Name="RND"
    <Emp ID="1" Name="Aj"/>
</dept>
<dept ID="2" Name="ENG">
<Emp ID="1" Name="Aj"/>
</dept>
<dept ID="3" Name="MECH">
    <Emp ID="1" Name="Aj"/>
</dept>
</root>
In Flex i am trying to access using below code
     treeData = event.result as XML;
     deptTree.dataProvider = treeData;
I am getting the below exception and
[RPC Fault faultString="org.w3c.dom.DOMException : INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified. " faultCode="Server.Processing" faultDetail="null"]
    at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::faultHandler()
    at mx.rpc::Responder/fault()
    at mx.rpc::AsyncRequest/fault()
    at NetConnectionMessageResponder/statusHandler()
    at mx.messaging::MessageResponder/status()
When i tried creating this XML locally and tried to access then i didn't faced any issue.
Please help me to resolve this issue.
Thanks in advance.

Hi
          I think this will help u
DOMException.INVALID_CHARACTER_ERR (Error Code  5)
W3C DOM Level 1
A DOMException.INVALID_CHARACTER_ERR is thrown  whenever an                         invalid or illegal character is specified, such  as in a name.
NOTE: Names in XML  can contain                         English letters (of any case), numbers (0-9),  underscores (_), periods(.)                         and hyphens (-). Names cannot begin with a  number, period or hyphen.                         Names can also contain a colon, but the use of  colons outside of namespaces                         should be avoided.
XML for <SCRIPT> uses the following  regular expression to determin                         if a name is valid:
/^[a-zA-Z_:][a-zA-Z0-9\.\-_:]*$/
Example:
function xmljsDOMExample() {
var xml;
xml = ""
+ "<?xml version=\"1.0\"?>"
+ "<ROOT>"
+ "<TAG1>"
+ "Hello"
+ "</TAG1>"
+ "</ROOT>";
//instantiate the W3C DOM Parser
var parser = new DOMImplementation();
//load the XML into the parser and get the  DOMDocument
var domDoc = parser.loadXML(xml);
//get the root node
var docRoot = domDoc.getDocumentElement();
//The following should raise a  DOMException.INVALID_CHARACTER_ERR
//because element names cannot contain the  "*" character
try {
domDoc.createElement("***");}
catch (e) {
if (e.code ==  DOMException.INVALID_CHARACTER_ERR) {
//display the error message
alert(parser.translateErrCode(e.code));
else {
alert("unexpected exception");
alert(e.code);
}// end function xmljsDOMExample
