You need to pull out buy_rate, sell_rate

import requests
from xml.etree import ElementTree as ET

response = requests.get('http://site.com/api/', stream=True)

tree = ET.fromstring(response.content)

for i in tree.findall('currency'):
    value = (i.find('title_alias'))
    print value

How to get to child elements?

Answer 1

import requests
from xml.etree import ElementTree as ET

response = requests.get('http://site.com/api/', stream=True)

tree = ET.fromstring(response.content)

for currency in tree.findall('currency'):
    title = currency.find('title_alias').text
    print(title)

    rates = currency.find('rates')
    print('\tBuy: ' + rates.find('buy_rate').text)
    print('\tSell: ' + rates.find('sell_rate').text)
