You can use getpath() to get xpath from element, for example :

import requests
from lxml import html

page = requests.get("http://www.w3schools.com/xpath/")
root = html.fromstring(page.text)
tree = root.getroottree()
result = root.xpath('//*[. = "XML"]')
for r in result:
    print(tree.getpath(r))

Output :

/html/body/div[3]/div/ul/li[10]
/html/body/div[3]/div/ul/li[10]/a
/html/body/div[4]/div/div[2]/div[2]/div[1]/div/ul/li[2]
/html/body/div[5]/div/div[6]/h3
/html/body/div[6]/div/div[4]/h3
/html/body/div[7]/div/div[4]/h3
