Import.io - REGEX 从 th 获取表 td 值

Question

我需要帮助。 我正在使用 import.io 并想使用正则表达式抓取表数据并希望从某个列中获取值，这是代码

<table>
   <tr>
      <td class='label'>No. Urut</td>
      <td class='titikdua'>:</td>
      <td>201</td>
   </tr>
   <tr>
      <td class='label'>Kode</td>
      <td class='titikdua'>:</td>
      <td>DF 045</td>
   </tr>
   <tr>
      <td class='label'>Warna</td>
      <td class='titikdua'>:</td>
      <td>HITAM</td>
   </tr>
   <tr>
      <td class='label'>Bahan</td>
      <td class='titikdua'>:</td>
      <td>KULIT</td>
   </tr>
   <tr>
      <td class='label'>Berat</td>
      <td class='titikdua'>:</td>
      <td>0 gr</td>
   </tr>
   <tr>
      <td class='label'>Info</td>
      <td class='titikdua'>:</td>
      <td>SOL : FIBER</td>
   </tr>
</table>
</div>
<div id='fr-stok'>
<table id='t01'>
   <tr>
      <th>Size</th>
      <th>Stok</th>
      <th>Pesanan</th>
      <th>Last Update</th>
   </tr>
   <tr>
      <td>38</td>
      <td>4</td>
      <td>0</td>
      <td></td>
   </tr>
   <tr>
      <td>39</td>
      <td>5</td>
      <td>0</td>
      <td>05 Oct 17, 15:39:53</td>
   </tr>
   <tr>
      <td>40</td>
      <td>11</td>
      <td>0</td>
      <td></td>
   </tr>
   <tr>
      <td>41</td>
      <td>4</td>
      <td>0</td>
      <td>08 Oct 17, 12:24:28</td>
   </tr>
   <tr>
      <td>42</td>
      <td>0</td>
      <td>0</td>
      <td>07 Oct 17, 14:22:07</td>
   </tr>
   <tr>
      <td>43</td>
      <td>6</td>
      <td>0</td>
      <td>04 Oct 17, 15:52:41</td>
   </tr>
</table>

我想获得 size 值并将其转换为 38,39,40,41,42,43 我如何使用正则表达式来做到这一点

Answer 1

<tr>\s*<td>\s*\K\d+

<tr> matches the characters <tr> literally (case sensitive)
\s*
matches any whitespace character (equal to [\r\n\t\f\v ])
* Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
<td> matches the characters <td> literally (case sensitive)
\s*
matches any whitespace character (equal to [\r\n\t\f\v ])
* Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
\K resets the starting point of the reported match. Any previously consumed characters are no longer included in the final match
\d+
matches a digit (equal to [0-9])
+ Quantifier — Matches between one and unlimited times, as many times as possible, giving back as needed (greedy)
