x.loadXML("<Record><Elm_1><Elm_3>null</Elm_3></Elm_1><Elm_2><Elm_4>null</Elm_4><Elm_5><Elm_6>null</Elm_6></Elm_5></Elm_2></Record>")
alert(x.xml)
x3=x.selectSingleNode("/Record/Elm_1/Elm_3")

x3new = x.createElement("Xa")
x3new.text="333"
x3.appendChild(x3new)
alert(x.xml)

x6=x.selectSingleNode("//Elm_6")

x6new = x.createElement("Xa")
x6new.text="666"
x6.appendChild(x6new)
alert(x.xml)

xid=x.selectSingleNode("//Elm_1")

xidnew = x.createAttribute("id")
xidnew.value="iddddddd"
