我正在尝试解析的 HTML 代码：

<div class="row" style="margin-left: 2%; margin-right: 2%;">
<table class="striped" style="margin-left: auto; margin-right: auto;">
<tbody>
<tr><td><a title="download Summer Girl Hair Spa &amp; Salon 1.3 apk " onclick="ga('send', 'event', 'button', 'download_ver', 'com.girlsbeautysalon.android_summerhairsalon_2016-12-26.apk');" href="/download-app/com.girlsbeautysalon.android_summerhairsalon/4_com.girlsbeautysalon.android_summerhairsalon_2016-12-26.apk/">1.3</a></td><td>Dec. 26, 2016</td></tr>
<tr><td><a title="download Summer Girl Hair Spa &amp; Salon  1.3   apk " onclick="ga('send', 'event', 'button', 'download_ver', 'com.girlsbeautysalon.android_summerhairsalon_2016-12-25.apk');" href="/download-app/com.girlsbeautysalon.android_summerhairsalon/2_com.girlsbeautysalon.android_summerhairsalon_2016-12-25.apk/"> 1.3 </a></td><td>Dec. 25, 2016</td></tr>
<tr><td><a title="download Summer Girl Hair Spa &amp; Salon  1.2   apk " onclick="ga('send', 'event', 'button', 'download_ver', 'com.girlsbeautysalon.android_summerhairsalon_2016-08-26.apk');" href="/download-app/com.girlsbeautysalon.android_summerhairsalon/3_com.girlsbeautysalon.android_summerhairsalon_2016-08-26.apk/"> 1.2 </a></td><td>Aug. 26, 2016</td></tr>
</tbody>
</table>
</div>

我在cheerio（NodeJs）上用于解析的代码：

   const row = $('.row');
   const version = [];
   const href = [];
   const data = [];

   row.find('tr').each(function (i, e) {
     version.push({"version": $(this).find("td a[title^='download']").text()});
     href.push({"href": $(this).find("td a").attr('href')});
     data.push({"data": $(this).find("td").eq(1).text()});
   });

您可以使用map方法并返回对象数组，其中每个对象都是数据形式 current tr。

const data = $('.row table tr').map(function() {
  const a = $(this).find('td:first-child a');
  const td = $(this).find('td:last-child');

  return {
    version: a.text(),
    href: a.attr('href'),
    date: td.text()
  }
}).get();

console.log(data)

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row" style="margin-left: 2%; margin-right: 2%;">
<table class="striped" style="margin-left: auto; margin-right: auto;">
