如何解析Selenium驱动程序元素? [英] How to parse Selenium driver elements?

问题描述

我是Selenium中的Python新手.我正在尝试抓取一些数据，但是我不知道如何解析这样的命令的输出:

I'm new in Selenium with Python. I'm trying to scrape some data but I can't figure out how to parse outputs from commands like this:

driver.find_elements_by_css_selector("div.flightbox")

我正在尝试搜索一些教程，但对Python却一无所获.

I was trying to google some tutorial but I've found nothing for Python.

能给我一个提示吗?

推荐答案

find_elements_by_css_selector()将为您返回

find_elements_by_css_selector() would return you a list of WebElement instances. Each web element has a number of methods and attributes available. For example, to get a inner text of the element, use .text:

for element in driver.find_elements_by_css_selector("div.flightbox"):
    print(element.text)

您还可以进行特定于上下文的搜索，以查找当前元素内的其他元素.考虑到我知道您在哪个网站上工作，下面是一个示例代码，用于在结果框中获取第一趟航班的起飞和到达时间:

You can also make a context-specific search to find other elements inside the current element. Taking into account, that I know what site are you working with, here is an example code to get the departure and arrival times for the first-way flight in a result box:

for result in driver.find_elements_by_css_selector("div.flightbox"):
    departure_time = result.find_element_by_css_selector("div.departure p.p05 strong").text
    arrival_time = result.find_element_by_css_selector("div.arrival p.p05 strong").text

    print [departure_time, arrival_time]
