Question

我正在尝试在以下HTML中使用selenium / python查找元素。类名会重复，并且检查器中的xpath选择器无法完成工作。我正在尝试获取class="p_oaimY p_1ntuX"中的美元金额数字。最接近的唯一div ID为AppFrameMain。如您所见，已经有一个元素与class="p_oaimY p_1ntuX"相同，并且内容Overview Dashboard在我要查找的元素之前。

    <main class="p_2WHWf" id="AppFrameMain" data-has-global-ribbon="false">
        <div class="p_IoKcO">
            <div class="p_1fbVL p_qRiFk">
                <div class="p_13E1y">
                    <div class="p_1jSPN">
                        <div class="p_1d9lu">
                            <div>
                                <h1 class="p_oaimY p_1ntuX">

                                                                    <div class="Txt6X">

                                                    </div>

以下xpath代码不起作用：

//*[@id="AppFrameMain"]/div/div/div[2]/div[2]/div[1]/div[1]/div/div/div/div[2]/div/div[1]/div/div/div[1]/p

Answer 1

使用WebDriverWait处理动态元素和Css Selector。

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


wait = WebDriverWait(driver, 20)
element=wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, '#AppFrameMain p.p_oaimY.p_1ntuX')))
print(element.text)

输出：

$10,384.75

Answer 2

要提取文本 $ 10,384.75 ，因为该元素是动态元素，您需要为_visibility_of_element_located_引入 WebDriverWait ，您可以使用以下内容解决方案：

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[text()='Total sales']//following::p[1]"))).get_attribute("innerHTML"))
