如何在保留html标签/结构的同时在html中查找/替换文本

function replaceText(textToFind, textToReplace) {
  const elements = document.querySelectorAll('*');
  elements.forEach((element) => {
    const childNodes = element.childNodes;
    for (let i = 0; i< childNodes.length; i++) {
      if (childNodes[i].nodeType === Node.TEXT_NODE) {
        const replacedText = childNodes[i].textContent.replace(textToFind, textToReplace);
        childNodes[i].textContent = replacedText;
      }
    }
  });
}

// 使用示例
replaceText('保留HTML标签/结构', '替换文本');
