I want to get the .text() of an element, excluding text nodes of descendants which don't match a selector, e.g. ":not(h2, h2 *, h3, h3 *)"

e.g. from the following example tree I want to get the string, "aaacccdddeee"

<div>
  aaa
  <h3>
    bbb
  </h3>
  ccc
  <div>
    ddd
  </div>
  eee
</div>

The following doesn't work,

$(':not(h2, h2 *, h3, h3 *)', context).text()

- because for each matched element, it returns all descendant text nodes, so it returns some text nodes multiple times - "aaabbbcccdddeeeddd"

$(context).text() only returns each descendant text node once, but it doesn't filter descendants with the selector, so it returns "aaabbbcccdddeee"

Is there an easy way to do this with jQuery?
