如何在 contenteditable div 中过滤用户粘贴的内容?

How to filter user pasted content in contenteditable div?

我有一个 div 允许 contenteditable。

<div contenteditable="true">
</div>

我想过滤所有从用户复制和粘贴的 html 标签(除了 ),这在 Dart 代码中如何实现?

myDiv.onPaste.listen((e) {
  // do filtering here and then insert the result imperatively
  // one or both of the following might be necessary to prevent
  // the default paste behavior happening as well.
  e.preventDefault();
  e.stopPropagation();
});
