How about (untested):
var oldList = document.getElementById( "listid" );
var newList = oldList.cloneNode( true );
for ( newItemText in textArray ) {
newLi = document.createNode("li");
newLiText = docuemnt.createTextNode( newItemText );
newLi.appendChild( newLiText );
newList.appendChild( newLi );
}
oldList.parentNode.replaceChild( oldList, newList );
Would this only re-render once when the list was replaced?
