解析此 HTML table 的最快方法是什么？

Question

我正在尝试解析从网站获取的 Node 中的 table。 table 看起来像这样。我想忽略 header 并只解析实际的交易主体。

        <tbody><tr class="dgHeader" style="font-weight:bold;">
            <th scope="col">Reference 1</th><th scope="col">Reference 2</th><th scope="col">Reference 3</th><th scope="col">Reference 4</th><th scope="col">Gross Amount</th><th scope="col">Discounts/Surcharges</th><th scope="col">Net Amount</th><th scope="col">Means of Payment</th><th scope="col">Form of Payment</th><th scope="col">Payment Folio</th><th scope="col">Branch</th><th scope="col">Time</th><th scope="col">Maturity Date</th><th scope="col">Payment date</th>             </tr><tr align="left">
            <td align="left">
                        <span id="ctl00_Contentplaceholder1_gvConcentracionPagos_ctl02_lblReferencia1">0000000000000000000000000000000X4D649G66</span>
                    </td><td align="left">
                        <span id="ctl00_Contentplaceholder1_gvConcentracionPagos_ctl02_lblReferencia2"></span>

                    </td><td align="right">

我一直在使用 Cheerio，但很难获得 id 标签以从 table 获取数据。

Answer 1

这样就解决了，也很容易拿到参考码

$ = cheerio.load(str, {
    ignoreWhitespace: true
  });

$('tr').each(function(i, tr){   
    var reference = $('#ctl00_Contentplaceholder1_gvConcentracionPagos_ctl02_lblReferencia1').text())
}
