javascript - 如何使用 xpath 获得硒中的非罢工价格金额？

问题描述

这是我试图自动化的网页的网址：

http://www.qaclickacademy.com/courses-description.php

我想使用 Selenium 和 XPath 定位器获取非删除线价格（目前为 20.00 美元）的价值。

包含我感兴趣的元素的 HTML 标记片段是：

<div class="course row" data-scroll-reveal=""
     style="-webkit-transform: translatey(24px);transform: translatey(24px);opacity: 0;-webkit-transition: -webkit-transform 0.66s ease-in-out 0s,  opacity 0.66s ease-in-out 0s;transition: transform 0.66s ease-in-out 0s,  opacity 0.66s ease-in-out 0s;-webkit-perspective: 1000;-webkit-backface-visibility: hidden;"
     data-scroll-reveal-initialized="true">

我尝试了很多方法，但到目前为止我一直无法找到解决方案

解决方案

这是python中的方法，它只会得到价格（20.00美元）。注意：这不适用于您是否有定价的两种情况。

def get_text_exclude_children(element):
    return driver.execute_script(
        """
        var parent = arguments[0];
        var child = parent.firstChild;
        var textValue = "";
        while(child) {
            if (child.nodeType === Node.TEXT_NODE)
                    textValue += child.textContent;
                    child = child.nextSibling;
        }
        return textValue;""",
        element).strip()

如何使用这里。

element = driver.find_element_by_xpath("(//div[@class='col-md-3 col-sm-4 price'])[1]")
price = get_text_exclude_children(element)
