like the below:

<ul>

<li>li1</li>

<li>li2</li>

<li>

<h4>a h4</h4>

<ul>

<li>li3</li>

<li>li4</li>

</ul>

</li>

</ul>

$("li") will return 5 elements but i only want 4 elements.

i want to select the li1,li2,li3 and li4,but i can't find a good way to select them if i do not assign them a className.

i'm think would you add a ":header" or ":input" like pseudo class to select the nodes only contains plain text or contains nothing??
