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

    The following gets a list of all attributes and their (sometimes translated to strings) values for me, using the PhantomJS or Chrome driver at least:

    elem.get_property('attributes')[0]
    

    To just get the names:

    x.get_property('attributes')[0].keys()

    You can find using element.get_property() method.

    from selenium import webdriver
    from selenium.webdriver.common.by import By
    
    driver = webdriver.Chrome()
    driver.get("https://www.ultimateqa.com/complicated-page/")
    
    logo = driver.find_element(By.XPATH, "//img[@id='logo']")
    attrs=[]
    for attr in logo.get_property('attributes'):
        attrs.append([attr['name'], attr['value']])
    print(attrs)
    

    Output:

    [['src', 'https://www.ultimateqa.com/wp-content/uploads/2019/01/horizontal_on_transparent_by_logaster-2.png'], ['alt', 'Ultimate QA'], ['id', 'logo'], ['data-height-percentage', '100'], ['data-actual-width', '912'], ['data-actual-height', '410']]

    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'}

    Here is my attempt at an answer. I do only tested it on the search box of google's homepage. I made use of @alecxe's answer above about 'outerHTML' Having obtained the html, I used a regular expression ([a-z]+-?[a-z]+_?)='?"? to match the attribute names. I think the regex would just have to be modified to match an increasing number of cases. But the essential name we need is "whatever is behind the equal sign."

    Given a webElement

    def get_web_element_attribute_names(web_element):
        """Get all attribute names of a web element"""
        # get element html
        html = web_element.get_attribute("outerHTML")
        # find all with regex
        pattern = """([a-z]+-?[a-z]+_?)='?"?"""
        return re.findall(pattern, html)
    

    Test it on the below code

    import re
    from selenium import webdriver
    
    driver = webdriver.Firefox()
    google = driver.get("http://www.google.com")
    
    driver.find_element_by_link_text("English").click()
    search_element = driver.find_element_by_name("q")
    get_web_element_attribute_names(search_element)
    

    output:

    ['class', 'id', 'maxlength', 'name', 'autocomplete', 'title', 'value', 'aria-label', 'aria-haspopup', 'role', 'aria-autocomplete', 'style', 'dir', 'spellcheck', 'type']
