Golang marshal dynamic xml element name

The xml file consists of two elements. Those elements have the same structure except for one element name:

<!-- first element -->
<PERSON>
  <ELEM1>...</ELEM1>
  <ELEM2>...</ELEM2>
  <ELEM3>...</ELEM3>
  <ELEM4>...</ELEM4>
</PERSON>


<!-- second element -->
<SENDER>
  <ELEM1>...</ELEM1>
  <ELEM2>...</ELEM2>
  <ELEM3>...</ELEM3>
  <ELEM4>...</ELEM4>
</SENDER>

Is it possible to define a struct such that the element name is dynamic?

type Person struct {
    XMLName string `xml:"???"` // How make this dynamic?
    e1 string `xml:"ELEM1"`
    e2 string `xml:"ELEM2"`
    e3 string `xml:"ELEM3"`
    e4 string `xml:"ELEM4"`
}

I tried to set a value to the XMLName property, but that didn't work.
