如何使用selenium/python从下面的html代码中找到以下文本(没有id、名称或引用)。只有满足一定条件(文件上传成功)后,才会出现上述文本。请参阅下面的部分HTML代码,此文本位于两个表之间,完整代码位于 link provided

我正在寻找的所需文本:

PCA提交请求成功完成

可以使用以下命令定位元素:

//font[contains(text(),'PCA Submit Request completed successfully')]

在此元素出现之前,可以设置一个暂停,如示例中所示:

from selenium.webdriver.support import expected_conditions

element = WebDriverWait(driver, 10).until(
    expected_conditions.presence_of_element_located((By.xPath, "xPath_to_element"))
)

或

browser.implicitly_wait(30)

你可以试试这个 XPath :

//font[text()='PCA Submit Request completed successfully.']

或

//font[contains(text(),'PCA Submit Request completed successfully.')]

如你所说,你必须满足某些条件才能尝试 显式等待 或 thread.sleep(time for waiting) 在里面爪哇和 time.sleep(5) 在里面蟒蛇不过是最坏的情况 显式等待 .
