Agouti could be problematic without a selector.parent method

[msecret]

Imagine the following nav:

<ul class="nav">
  <li class="nav-item">
    <a>cf-deck org</a>
  </li>
  <ul class="nav">
    <li class="nav-item">
      <a>spaces</a>
    </li>
    ...
  </ul>
  <li class="nav-item">
    <a>cf org</a>
  </li>
  <ul class="nav">
    <li class="nav-item">
      <a>spaces</a>
    </li>
    ...
  </ul>
</ul>

I want to write agouti functionality to click on the spaces like for a certain org. I start this by finding the link for the org by it's name:

nav.FindByLink('cf org')

Which puts me at the second <a> withing ul li. Now I want to get to the ul above and from there, go to the spaces link. In jquery this would be like nav.parent('ul').children('spaces'). But I can't do this in agouti because there's no parent method. There's no parent selector in CSS, making this impossible.

Any ideas on how I could write a test case like this without a parent method?
