The count information is included in the XML data:

 <count id="0">
    <tag k="nodes" v="0"/>
    <tag k="ways" v="36"/>
    <tag k="relations" v="0"/>
    <tag k="total" v="36"/>
  </count>
.....
  <count id="0">
    <tag k="nodes" v="0"/>
    <tag k="ways" v="9"/>
    <tag k="relations" v="0"/>
    <tag k="total" v="9"/>
  </count>
.....
  <count id="0">
    <tag k="nodes" v="0"/>
    <tag k="ways" v="16"/>
    <tag k="relations" v="0"/>
    <tag k="total" v="16"/>
  </count>
......
  <count id="0">
    <tag k="nodes" v="0"/>
    <tag k="ways" v="61"/>
    <tag k="relations" v="0"/>
    <tag k="total" v="61"/>
  </count>


It is just a bit more work to filter it out.
