how do i find node and its child nodes using selenium with python

问题

Please let me know the code syntax how to use Node.childNodes from the documentation http://docs.python.org/library/xml.dom.html#module-xml.dom I am beginner to python and selenium. I have tried using:

elem = self.browser.find_element_by_id("pie4")
x = elem.childNodes
print x

I have also tried:

self.dom.getElementsByTagName('path')[0].firstChild.data

But both fail.

回答1:

elem is WebElement. You could use elem.find_elements_by_xpath() to select relevant child elements e.g.:

#!/usr/bin/env python
from contextlib import closing

from selenium.webdriver import Chrome as Browser # pip install selenium
from selenium.webdriver.support.ui import WebDriverWait

with closing(Browser()) as browser:
    browser.get('http://stackoverflow.com/q/9548523')
    elem = WebDriverWait(browser, timeout=10).until(
        lambda br: br.find_element_by_class_name('related'))
    children = elem.find_elements_by_xpath('./*')
    for child in children:
        print("<%s> %r" % (child.tag_name, child.text[:60]))
