如何从表格行中删除特定单词？

Question

我只想使用python从下表中抓取代码

如图中所示，您可以看到我只想废弃CPT，CTC，PTC，STC，SPT，HTC，P5TC，P1A，P2A，P3A，P1E，P2E，P3E。该代码可能会不时更改，例如添加P4E或删除P1E。

上表的HTML代码是：

<table class="list">
   <tbody>
      <tr>
         <td>
            <p>PRODUCT<br>DESCRIPTION</p>

         <td>
            <p><strong>Time Charter:</strong> CPT, CTC, PTC, STC, SPT, HTC, P5TC<br><strong>Time Charter Trip:</strong> P1A, P2A, P3A,<br>P1E, P2E, P3E</p>
         </td>
         <td><strong>Voyage: </strong>C3E, C4E, C5E, C7E</td>
      </tr>
      <tr>

      </tr>

         <td>

         </td>
      </tr>
      <tr>
         <td>
            <p>FINAL SETTLEMENT PRICE</p>

         </td>
         <td colspan="2" rowspan="1">

      </tr>
      <tr>
         <td>
            <p>CONTRACT SERIES</p>
         </td>
         <td colspan="2" rowspan="1">

      </tr>
      <tr>

如果您的用例是擦除所有文本：

您必须为所需的WebDriverWait引入visibility_of_element_located()，并且可以使用以下任何一个Locator Strategies：

• 使用CSS_SELECTOR：

  driver.get('https://www.eex.com/en/products/global-commodities/freight')
  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "article div:last-child table>tbody>tr td:nth-child(2)>p"))).text)
  

• 使用XPATH：

  driver.get('https://www.eex.com/en/products/global-commodities/freight')
  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//h3[text()='Contract Specifications']//following::table[1]/tbody/tr//following::td[1]/p"))).text)
  

• 控制台输出：

  Time Charter: CPT, CTC, PTC, STC, SPT, HTC, P5TC
  Time Charter Trip: P1A, P2A, P3A,
  P1E, P2E, P3E
  

• 注：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
