檢查是否有任何子元素滿足從同級DOM開始的特定單詞

我想了解這些兄弟姐妹中的哪一個具有特定的文本“應用程式”。由于沒有絕對參考，我從“DOD”這個詞開始搜索。之后，我搜索：following-sibling::td/div/table/tbody 然后我想知道以下任何“tr”（在本例中為 2）是否包含“app”一詞。然后，導航到該元素并單擊它。

以下是 HTML：

<tr align="center">
    <td align="left" valign="top" style="width:30%;">Application</td>
    <td align="left" valign="top" style="width:30%;">DOD 11-24-2021</td>
    <td align="right" valign="middle" style="width:32%;">
        <div>
            <table class="Nested_ChildGrid" cellspacing="0" cellpadding="0" rules="rows" border="0" id="ctl00_ContentPlaceHolder1_gridViewEvents_ctl15_gridViewEventDocs" style="color:Black;border-width:0px;border-style:None;width:100%;border-collapse:collapse;">
                <tbody>
                    <tr align="center">
                        <td align="center" valign="middle" style="width:70px;">
                        <td align="left" valign="middle" style="width:75%;">
                            <span id="ctl00_ContentPlaceHolder1_gridViewEvents_ctl15_gridViewEventDocs_ctl02_lblDocDesc">Application</span>
                        </td>
                        <td class="Hide" style="width:90px;">&nbsp;</td>
                        <td style="width:40px;">3</td>
                        <td class="Hide">4</td>
                        <td class="Hide">18200854</td>
                        <td align="right" valign="middle" style="width:60px;">

                        </td>
                    </tr>

這是我一直在嘗試但沒有成功的一些代碼：

path = driver.find_element(By.XPATH, '//td[contains(text(), "DOD")]/following-sibling::td/div/table/tbody/*/*/span[contains(text(), "app")]/parent::*/td[5]/a').click()

先感謝您！

uj5u.com熱心網友回復：

要識別帶有文本為DOD<td>的元素 并找到相應的帶有文本為App的元素，然后單擊帶有文本為View的相關標簽，您需要為element_to_be_clickable()引入WebDriverWait，您可以使用以下定位器策略：<span><a>

• 使用XPATH：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//td[starts-with(., 'DOD')]//following-sibling::td[.//span[starts-with(., 'App')]]//following-sibling::td[.//a[text()='View']]"))).click()
  

• 注意：您必須添加以下匯入：

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