I have to remove all `ul` within `li` except the current `li`.

```
<ul>
        <li id="Li0">
            <ul>
                <li><span>Childnode1</span></li></ul>
        </li>
        <li id="Li1">
            <ul>
                <li><span>Childnode2</span></li></ul>
        </li>
        <li id="Li2">
            <ul>
                <li><span>Childnode3</span></li></ul>
        </li>
        <li id="Li3">
            <ul>
                <li><span>Childnode4</span></li></ul>
        </li>
        <li id="Li4">
            <ul>
                <li><span>Childnode5</span></li></ul>
        </li>
        <li id="Li5">
            <ul>
                <li><span>Childnode6</span></li></ul>
        </li>
    </ul>

```

So If i click on the `li` with id 'li4' every other `li` that are previous to this `li` or next to this `li` should have there `ul` to be removed from dom. 

I was thinking of using the `.not` operator in jquery but till now not able to do this.
