Find all the target elements (there are some ways to do this), and then use built-in function len() to get the count. For example, if you mean to count only direct child elements of root :

from lxml import etree 
doc = etree.parse("file.xml")
root = doc.getroot()

result = len(root.getchildren())

or, if you mean to count all elements within root element :

result = len(root.xpath(".//*"))
