检查是否有任何子元素满足从兄弟开始的特定单词 DOM

Question

我想搜索这些兄弟姐妹中哪一个有特定的文本'app'。由于没有绝对引用，我从 'DOD' 这个词开始搜索。之后，我搜索：following-sibling::td/div/table/tbody 然后我想知道以下 'tr'（在本例中为 2）是否有单词 'app'。然后，导航到该元素并单击它。

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>

下面是一些我一直在尝试但没有成功的代码：

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()

提前致谢！

Answer 1

将 <td> 元素的文本标识为 DOD 并找到相应的 <span> 文本为App 然后点击相关的 <a> 标签，文本为 View 你需要诱导 WebDriverWait for the and you can use the following :

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
