In the Python Selenium module, once I have a WebElement object I can get the value of any of its attributes with get_attribute():

f

    It is not possible using a selenium webdriver API, but you can execute a javascript code to get all attributes:

    driver.execute_script('var items = {}; for (index = 0; index < arguments[0].attributes.length; ++index) { items[arguments[0].attributes[index].name] = arguments[0].attributes[index].value }; return items;', element)
    

    Demo:

    >>> from selenium import webdriver
    >>> from pprint import pprint
    >>> driver = webdriver.Firefox()
    >>> driver.get('https://stackoverflow.com')
    >>> 
    >>> element = driver.find_element_by_xpath('//div[@class="network-items"]/a')
    >>> attrs = driver.execute_script('var items = {}; for (index = 0; index < arguments[0].attributes.length; ++index) { items[arguments[0].attributes[index].name] = arguments[0].attributes[index].value }; return items;', element)
    >>> pprint(attrs)
    {u'class': u'topbar-icon icon-site-switcher yes-hover js-site-switcher-button js-gps-track',
     u'data-gps-track': u'site_switcher.show',
     u'href': u'//stackexchange.com',
     u'title': u'A list of all 132 Stack Exchange sites'}
    

    For completeness sake, an alternative solution would be to get the tag's outerHTML and parse the attributes using an HTML parser. Example (using BeautifulSoup):

    >>> from bs4 import BeautifulSoup
    >>> html = element.get_attribute('outerHTML')
    >>> attrs = BeautifulSoup(html, 'html.parser').a.attrs
    >>> pprint(attrs)
    {u'class': [u'topbar-icon',
                u'icon-site-switcher',
                u'yes-hover',
                u'js-site-switcher-button',
                u'js-gps-track'],
     u'data-gps-track': u'site_switcher.show',
     u'href': u'//stackexchange.com',
     u'title': u'A list of all 132 Stack Exchange sites'}
