javascript 如何找到包含文本的 DOM 节点?

javascript how to find that DOM node that contains a text?

给定一个获取的 html 页面,我想找到包含一部分文本的特定节点。我想最困难的方法是一个一个地迭代所有节点,尽可能深入,并针对每种情况进行搜索,例如.includes()

但是怎样才是明智之道呢?一定有什么东西,但我无法 google 正确地

    response = axios.get(url);
    let parsedHtml = parser.parseFromString(response.data, 'text/html');
    for (let i = 0; i < parsedHtml.children.length; i++)
       if (parsedHtml.children[i].textContent.includes('hello'))
          console.log(parsedHtml.children[i])

*没用

*示例代码

<html>
 <body>
  <div>dfsdf</div>
  <div>
   <div>dfsdf</div>
   <div>dfsdf</div>
  </div>
  <div>
   <div>
    <div>hello</div>
   </div>
  </div>
  <div>dfsdf</div>
 </body>
 </html>

我想检索 <div>hello</div> 作为节点元素

在几乎确信我必须以经典方式遍历 DOM 之后,我在这里 Javascript: How to loop through ALL DOM elements on a page? 找到了这确实很棒:

    let nodeIterator = document.createNodeIterator(
        parsedHtml,
        NodeFilter.SHOW_ELEMENT,
        (node) => {
            return (node.textContent.includes('mytext1')
                || node.textContent.includes('mytext2'))
                && node.nodeName.toLowerCase() !== 'script' // not interested in the script
                && node.children.length === 0 // this is the last node
                ? NodeFilter.FILTER_ACCEPT : NodeFilter.FILTER_REJECT;
        }
    );
    let pars = [];
    let currentNode;

    while (currentNode = nodeIterator.nextNode())
        pars.push(currentNode);
    console.log(pars[0].textContent); // for example
