It's simple. Instead of getting this...

[body]
  |
  +-[unknown attrib1="1" attrib2="2" attrib3="3" style="display: span"]
     |
     +-[child1]
     |
     +-[child2]
     |
     +-[child3]

...You get this...

[body]
  |
  +-[unknown attrib1="1" attrib2="2" attrib3="3" style="display: none"]
  |
  +-[child1]
  |
  +-[child2]
  |
  +-[child3]
  |
  +-[/unknown style="display: none"]
