Using my code I get `-1` ... I should get 2 instead.

I need to get the position of an `li` with class `focus` within `ul` without considering the div tags like `<div class="clm-XXXX">`

How should I change my code?
Please note (I cannot change the HTML structure).

```
   <div class="snippet-content">
<ul class="layout-1">
    <div class="clm-1">
        <li>content 1</li>
    </div>
    <div class="clm-1">
        <li>content 2</li>
        <li class="focus">content 3</li>
        <li>content 4</li>
        <li>content 5</li>
    </div>
    <div class="clm-3">
        <li>content 6</li>
        <li>content 7</li>
    </div>
</ul>

```
