Question

我正在尝试从html表td中检索所有元素，但是当我尝试通过具有多个条件的xpath查找元素时，它无法检索0个元素，因此在单个条件下获取所有值没有问题。到目前为止，我的问题可能是在html元素的顺序中。

这是使用xpath按条件进行搜索的方法，效果很好： "//input[@class='managebtn'][@value='repost']"

这是我要达到的目标而没有达到的结果：

"//td[contains(text(),'manage')]/div[@class='regular']/form[@class='manage']/input[@class='managebtn'][@value='repost']"

以下html表是我要阅读的表”

 <tbody aria-live="polite" aria-relevant="all">
  <tr class="posting-row odd ui-state-default" role="row">
     <td class="status expired">
        <small class="gc" style="background:">
        Expired               </small>
     </td>
     <td class="buttons expired"></td>
  </tr>
  <tr class="posting-row even ui-widget-content" role="row">
     <td class="status deleted">
        <small class="gc" style="background:">
        Deleted               </small>
     </td>
     <td class="buttons deleted">
        <div class="regular">
           <form action="https://" method="GET" class="manage display">
              <input type="hidden" name="action" value="display">
              <input type="submit" name="go" value="display" class="managebtn">
           </form>
           <form action="https://" method="GET" class="manage ">
              <input type="hidden" name="action" value="repost">
              <input type="submit" name="go" value="repost" class="managebtn">
           </form>
        </div>
     </td>
   
  </tr>
  <tr class="posting-row odd ui-state-default" role="row">
     <td class="status deleted">
        <small class="gc" style="background:">
        Deleted               </small>
     </td>
     <td class="buttons deleted">
        <div class="regular">
           <form action="https://" method="GET" class="manage display">
              <input type="hidden" name="action" value="display">
              <input type="submit" name="go" value="display" class="managebtn">
           </form>
           <form action="https://" method="GET" class="manage ">
              <input type="hidden" name="action" value="repost">
              <input type="submit" name="go" value="repost" class="managebtn">
           </form>
        </div>
     </td>
  </tr>
  <tr class="posting-row even ui-widget-content" role="row">
     <td class="status deleted">
        <small class="gc" style="background:">
        Deleted               </small>
     </td>
     <td class="buttons deleted">
        <div class="regular">
           <form action="https://" method="GET" class="manage display">
              <input type="hidden" name="action" value="display">
              <input type="submit" name="go" value="display" class="managebtn">
           </form>
           <form action="https://" method="GET" class="manage ">
              <input type="hidden" name="action" value="repost">
              <input type="submit" name="go" value="repost" class="managebtn">
           </form>
        </div>
     </td>
    
  </tr>

仅当第一列的值是 Expired （过期）时，我才想从第二列（值='repost'）中检索所有值。
由于该表在列中包含多个元素，因此可能看起来有些疏忽。

由于这些列的内容如下：

      <th data-column="0" class="tablesorter-header tablesorter-headerUnSorted ui-widget-header ui-corner-all ui-state-default" tabindex="0" scope="col" role="columnheader" aria-disabled="false" unselectable="on" style="user-select: none;" aria-sort="none" aria-label="status: No sort applied, activate to apply an ascending sort">
   <div class="tablesorter-wrapper" style="position:relative;height:100%;width:100%">
      <div class="tablesorter-header-inner">
         status <i class="tablesorter-icon ui-icon ui-icon-carat-2-n-s"></i>
      </div>
   </div>
</th>
<th class="sorter-false tablesorter-header tablesorter-headerUnSorted ui-widget-header ui-corner-all ui-state-default" data-column="1" scope="col" role="columnheader" aria-disabled="true" unselectable="on" style="user-select: none;" aria-sort="none" aria-label="manage: No sort applied, sorting is disabled">
   <div class="tablesorter-wrapper" style="position:relative;height:100%;width:100%">
      <div class="tablesorter-header-inner">
         manage  <i class="tablesorter-icon ui-icon"></i>
      </div>
   </div>
</th>

我不知道是否有可能这样的一行代码来获取我需要的值：

driver.findElement(By.xpath("//th[@class='sorter-false tablesorter-header tablesorter-headerUnSorted ui-widget-header ui-corner-all ui-state-default' and @text()='manage']"));

这是表格的样子：

要在状态为已过期的项目中将属性为 value 的元素标识为repost，您必须得出{{ 3}}作为VisibilityOfAllElementsLocatedBy()，则可以使用以下基于WebDriverWait的xpath：

new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.XPath("//tr[contains(@class, 'posting-row')][./td[@class='status expired']]//td[@class='buttons expired']//input[@class='managebtn' and @value='repost']")));

通过 SeleniumExtras.WaitHelpers ，您可以使用：

new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.XPath("//tr[contains(@class, 'posting-row')][./td[@class='status expired']]//td[@class='buttons expired']//input[@class='managebtn' and @value='repost']")));

C＃Selenium如果满足两个条件（多个条件），请选择所有列元素
