Question

我使用DataMiner Chrome扩展程序从网站上抓取数据。在Chrome中，我使用了Inspect Element＆gt;右键单击Inspector中的元素＆gt;复制XPath方法以生成我需要的数据的XPath。这很有效，但是当我进行刮擦时，我会反复重复第一次结果输入。

在检查第二个结果并复制XPath时，我注意到ID中有一个序列号。以下是第一个数据点的XPath：

Entry 1 Company: //*[@id="Repeater_Results_ctl01_tCell1"]/h3/b/a
Entry 2 Company: //*[@id="Repeater_Results_ctl02_tCell1"]/h3/b/a

我可以为序号插入变量吗？还是有更好的方法来解决它？

这是一个示例页面：

<table border="0" cellpadding="0" cellspacing="0" class="tablelist" id="TsTable">
<tr>
   <th class="col1">Organization</th>
   <th>
      <div class="tCol2">Location</div>
   </th>
</tr>
<tr>
   <td id="Repeater_Results_ctl01_tCell1" class="tCell1">
      <h3><b><a href="/organization-search/details.aspx?slne=8118" target="_blank">Organization A</a></b></h3>
      <span class="nm">John Doe</span></h3>
      <p style="margin-bottom:0"><b>Phone:</b> 555-123-4567<br /><span class="webp"><b>Web: </b><a href="http://www.companya.com" target="_blank">www.companya.com</a></span><br />
      </p>
      <div class="locMobile"><b>LOCATION</b><br />
         <span style="white-space:nowrap">Anywhere,&nbsp;USA</span> <br />
         12345<br />
         <small><strong>0 miles</strong></small>
      </div>
   </td>
   <td id="Repeater_Results_ctl01_tCell2" class="tCell2a">
      <div class="tCell2"><b>LOCATION:</b><br />
         <span class="nw">Anywhere,&nbsp;USA</span><br />
         12345<br />
         <small><strong>0 miles</strong></small> 
      </div>
   </td>
</tr>
<tr>
   <td id="Repeater_Results_ctl01_tCell4" colspan="2" class="tCell4a">
      <p><b>Services:</b> XYZ Services</p>
      <p><strong>Locations:</strong> Anywhere, USA</p>
   </td>
</tr>
<tr>
   <td id="Repeater_Results_ctl02_tCell1" class="tCell1">
      <h3><b><a href="/organization-search/details.aspx?slne=2982" target="_blank">Organization B</a></b></h3>

         12345<br />
         <small><strong>6.7 miles</strong></small>
      </div>
   </td>
   <td id="Repeater_Results_ctl02_tCell2" class="tCell2a">
      <div class="tCell2"><b>LOCATION:</b><br />
         <span class="nw">Somewhere,&nbsp;USA</span><br />
         12345<br />
         <small><strong>6.7 miles</strong></small> 
      </div>
   </td>
</tr>
<tr>
   <td id="Repeater_Results_ctl02_tCell4" colspan="2" class="tCell4a">

感谢您的帮助！

您可以使用包含方法，就像这样

    //*[contains(@id, "_tCell1")]/h3/b/a
