如何根据节点的日期划分XML元素列表并使用javscript对其进行解析？

// 加载XML文档
const xmlString = "<data><entry><title>Entry 1</title><date>2022-10-01</date></entry><entry><title>Entry 2</title><date>2022-10-02</date></entry><entry><title>Entry 3</title><date>2022-10-03</date></entry></data>";
const parser = new DOMParser();
const xmlDoc = parser.parseFromString(xmlString, "text/xml");

// 获取XML元素列表
const entryList = xmlDoc.getElementsByTagName("entry");

// 按日期分类
const entryByDate = {};

// 遍历元素列表并按日期分类
for (let i = 0; i < entryList.length; i++) {
  const entry = entryList[i];
  const dateNode = entry.getElementsByTagName("date")[0];
  const date = new Date(dateNode.textContent);
  const formattedDate = `${date.getFullYear()}-${date.getMonth() + 1}-${date.getDate()}`;

  if (entryByDate[formattedDate]) {
    entryByDate[formattedDate].push(entry);
  } else {
    entryByDate[formattedDate] = [entry];
  }
}

// 输出分类结果
for (const date in entryByDate) {
  console.log(`Entries for ${date}:`);
  const entries = entryByDate[date];
  for (let i = 0; i < entries.length; i++) {
    const title = entries[i].getElementsByTagName("title")[0].textContent;
    console.log(title);
  }
  console.log("-------------------");
}
