You appear to have got the name of the parser wrong. You are parsing an XML document, so you need to use lxml-xml instead of lxml.

Try replacing

soup = BeautifulSoup(r.text , 'lxml')

with

soup = BeautifulSoup(r.text , 'lxml-xml')

After making this change to your get_news_calendar function I get the following output running it on your example XML file:

German Flash Manufacturing PMI EUR <date>04-21-2017</date> 7:30am Medium 58.1 58.3

Consider directly using lxml and run xpath on all <event> nodes as .text() can retrieve CData content.

import requests
import lxml.etree as et

def get_news_calendar():        
    r = requests.get('http://www.forexfactory.com/ffcal_week_this.xml')
    data = et.fromstring(r.text.encode("utf-8"))

    events = data.xpath('//event')
    for event in events:
        print(event.find('title').text, event.find('country').text,
              event.find('date').text, event.find('time').text, 
              event.find('impact').text, event.find('forecast').text, 
              event.find('previous').text)

get_news_calendar()
