python - 如何使用 Selenium Python 定位元素

Question

我正在尝试在以下 HTML 中使用 selenium/python 查找元素。类名会重复出现，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 是 AppFrameMain。正如您所看到的，已经有一个元素具有相同的 class="p_oaimY p_1ntuX"，其内容 Overview Dashboard 位于我想要查找的元素之前。

    <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">
                                    Overview dashboard

                                                    </div>

下面的 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

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，并且可以使用以下命令解决办法:

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