No, this is still not what I need ;)
Let me give you a complete example of what I want:
Case 1)
<div id="myElement">
<div class="MyTargetClass" id="found">
<div class="SomeOtherClass"></div>
</div>
</div>
<div class="MyTargetClass"></div>
Case 2)
<div id="myElement">
<div class="SomeOtherClass">
<div class="MyTargetClass" id="notFound"></div>
</div>
</div>
<div class="MyTargetClass"></div>
-> I want to fetch the *direct* child of myElement if it has a class of
MyTargetClass.And I get a reference to myElement as a DOM element.
So in case 1, it should return an element (the one with id="found"), but in
case 2 it should return NOTHING (the element id="notFound" is not a direct
child).
How would you achieve that in Qooxdoo?
