python selenium如何从谷歌获取链接

Question

How do I get a link from Google? I tried the following ways, but none of them worked:

1. find_elements_by_xpath("//*[@class='r']/@href")
2. driver.find_element_by_xpath("//a").get_attribute("href")
3. driver.find_element_by_xpath("//a").get_attribute(("href")[2])

I am receiving "none"

I need to get google link, not link to the site (eg not www.stackoverflow.com). It's highlighted on this image:

You maye have multiple issues here: First and third options are a not a valid xpath. Second options may find more than one matches, so it will return the first that fits, which is not necessarily the one you want. So I suggest:

1. Make find specific enough to locate a proper element. I'd suggest find_element_by_link_text if you know the name of the link you are going to choose:

    link = driver.find_element_by_link_text('Stack Overflow') 

2. Given you chose the right link, you should be able to get the attribute:

    href = link.get_attribute('href') 

3. If the first statement throws an exception (most likely element not found ), you may need to wait for the element to appear on the page, as described here
