Java：如何迭代表格單元以隨機更改表格捕獲數字

Question

下面是我的表格結構，我使用Selenium使用Java遍歷所有行並捕獲數字「00955222222222」，它將在任意單元格中隨機顯示。一旦我得到這個，我已經讀完整行並獲得授權代碼。我可以實現直到循環行和列。但需要輸入我如何獲得授權碼？請幫助

我喜歡這樣的事情寫功能，因爲它們很可能被重複使用。下面的功能需要您正在搜索的手機號碼並返回授權碼。基本邏輯是抓住TR並通過它們循環尋找包含移動號碼的那個。一旦你發現TR，使用正則表達式從TR中找到認證碼並返回。

public static String GetAuthCode(String mobileNumber) 
{ 
    List<WebElement> rows = driver.findElements(By.cssSelector("tr")); 
    for (WebElement row : rows) 
    { 
     String text = row.getText(); 
     if (text.contains(mobileNumber)) 
     { 
      String regex = "Your authentication code is: (\\d+)"; 
      Pattern pattern = Pattern.compile(regex); 
      Matcher matcher = pattern.matcher(text); 

      if (matcher.find()) 
      { 
       return matcher.group(1); 
      } 
     } 
    } 

    return "not found"; 
}
