使用Selenium Webdriver和Python从XPath中提取链接?

Rob*_*nar 7 python python-2.7 selenium-webdriver

我对Seleniun WebDriver和Python很陌生,我的问题可能很基础.

所以,我有以下HTML代码:

<a class="wp-first-item" href="admin.php?page=account">Account</a>

而且我想提取HREF出来的,是XPath的手段,知道它的XPath是".//*[@id='toplevel_page_menu']/ul/li[2]/a".

我怎么做?

driver.find_element_by_xpath(".//*[@id='toplevel_page_menu']/ul/li[2]/a").link

要么

driver.find_element_by_xpath(".//*[@id='toplevel_page_menu']/ul/li[2]/a").href

似乎没有工作,导致:

AttributeError: 'WebElement' object has no attribute 'link'

我期待结果如此"admin.php?page=account".

你可以使用get_attribute:

element = driver.find_element_by_xpath(".//*[@id='toplevel_page_menu']/ul/li[2]/a")
href = element.get_attribute('href')
print href

通常我使用Selenium导航到一个页面,检索源并使用BeautifulSoup解析它:

from BeautifulSoup import BeautifulSoup

# On the current page
source = driver.page_source
soup = BeautifulSoup(source)

href = soup('<the tag containing the anchor>',{'id':'toplevel_page_menu'})[0]('ul')[0]('li')[2]('a')[0]['href']

不幸的是,BeautifulSoup不支持xpath,所以上面是你的xpath的BS表示(据我所知).
