Dynamic golang xml structure

I'm working with xml api and trying to parse incoming documents. Documents have structures

<md>
  <command n="status">
    <item atr1="" atr2=""/>
  </command>
</md>
<md>
  <command n="check">
    <item atr3="" atr4=""/>
  </command>
</md>

All xml requests come to one URL. Is it the right way to parse attribute of the command tag and then to construct the right golang structure with <item atr1="" atr2=""/> or <item atr3="" atr4=""/>?
