Answer 1

With jQuery you can do this:

$("#div1 ul li:contains('Hello')").remove();

Answer 2

var div = document.getElementById('div1'),
    ul = div.getElementsByTagName('ul')[0],
    li = ul.getElementsByTagName('li'),
    len = li.length;

// Go backwards so that removing items has no effect
while (len--) {
    if ( /Hello/.test(getText(li[len])) ) {
        ul.removeChild(li[len]);
    }
}

function getText(node) {
    var s = '';
    node = node.firstChild;
    if ( node ) do {
        if ( node.nodeType === 3 ) {
            s += node.data;
        }
        if ( node.nodeType === 1 ) {
            s += getText(node);
        }
    } while ( node = node.nextSibling );
    return s;
}

Answer 3

function removeLi()
{
    var DIV = document.getElementById('div1');
    var LI = DIV.getElementsByTagName('li');
    LI[0].parentNode.removeChild(LI[0]); //remove the first li
    //LI[1].parentNode.removeChild(LI[1]); //remove the second li
}
