python selenium get child element
from selenium import webdriver
driver = webdriver.Firefox()

header = driver.find_element_by_id("header")
#Here you can get all the child elements by css:
all_children_by_css = header.find_elements_by_css_selector("*")

all_children_by_xpath = header.find_elements_by_xpath(".//*")
#And if you just want one element you can take it by index:
all_children_by_xpath[0] #for first item
all_children_by_xpath[1] #for the 2
