"undeclared reference to namespace prefix " error

I use xml to get label for my website.

the xml generated from database file look like this

<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'

<z:row LABEL_KEY='_site_map' Label_LNG='Site Map' Label_ID='4' c3='4' Language_ID='1'/>
</rs:data>
</xml>

my function is

    Public Function Get_Item(Temp_L_KEY)
        Set XMLL = Server.CreateObject("MSXML2.DOMDocument.4.0") 
        XMLL.Async = False
        XMLL.Load (Server.MapPath(Replace(application("root"),"/","\") & "system\db\dict\SITE_xml_" & Temp_LNG_ID & ".xml"))
        Get_Item=xmll.selectSingleNode("xml/rs:data/z:row[@LABEL_KEY='" & lcase(Temp_L_KEY) & "']").attributes(1).value
            if err.number <>0 then
                Get_Item=Temp_L_KEY
            end if
    End Function

and i get that error

msxml4.dll error '80004005'

Reference to undeclared namespace prefix: 'rs'.

You have not declared any namespaces for MSXml.

You can add the following after loading the document and before selection:

XMLL.setProperty("SelectionNamespaces", "xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882' xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882' xmlns:rs='urn:schemas-microsoft-com:rowset'");
