対象の div への参照を取得して、それぞれの親から削除するだけです。
もしかして、これに少し似てる?
編集:ドキュメント自体ではなく、クローンに対して操作を実行するコードを追加しました。div 要素には .getElementById メソッドがないため、要素を手動で検索します。
window.addEventListener('load', myInit, false);
function removeFromDocument()
{
// 1. take car of the element with id='quot'
var tgt = document.getElementById('quot');
var parentNode = tgt.parentNode;
parentNode.removeChild(tgt);
// 2. take care of elements whose class == 'quote'
var tgtList = document.getElementsByClassName('quote');
var i, n = tgtList.length;
for (i=0; i<n; i++)
{
// we really should be checking to ensure that there aren't nested instances of matching divs
// The following would present a problem - <div class='quote'>outer<div class='quote'>inner</div></div>
// since the first iteration of the loop would also remove the second element in the target list,
parentNode = tgtList[i].parentNode;
parentNode.removeChild(tgtList[i]);
}
// 3. remove the containing div
var container = document.getElementById('div_text');
container.outerHTML = container.innerHTML;
}
function cloneAndProcess()
{
var clonedCopy = document.getElementById('div_text').cloneNode(true);
var tgt;// = clonedCopy.getElementById('quot');
var i, n = clonedCopy.childNodes.length;
for (i=0; i<n; i++)
{
if (clonedCopy.childNodes[i].id == 'quot')
{
tgt = clonedCopy.childNodes[i];
var parentNode = tgt.parentNode;
parentNode.removeChild(tgt);
break; // done with for loop - can only have 1 element with any given id
}
}
