Ah, then it becomes this! So far my first lesson in Python.
I do miss the end statements, but it's all done by position and I
already always worked that way, but still.

#!/usr/bin/env python2
# -*- coding: utf-8 -*-

import argparse, socket, urllib2, sys
from urllib2   import urlopen
from xml.etree import cElementTree as ET

parser = argparse.ArgumentParser(description='Get Status of Backend Encoders.')

parser.add_argument('--card', type=str, required=False, 
        metavar='<device>', default='/dev/video0',
        help='tv capture device, default </dev/video0>')

parser.add_argument('--host', type=str, required=False, 
        metavar='<hostname>', default=socket.gethostname(),
        help='backend hostname,  default <local hostname>')

args = parser.parse_args()
URL1 = 'http://{}:6544/Capture/GetCaptureCardList?HostName={}' \
        .format(args.host, args.host)
URL2 = 'http://{}:6544/Dvr/GetEncoderList'.format(args.host)

try:
        response = ET.parse(urlopen(URL1))
except:
        raise SystemExit('GetCaptureCardList failed, is the backend running?')
for element1 in response.findall('CaptureCards/CaptureCard'):
        if element1.findtext('VideoDevice') == args.card:
                try:
                        response = ET.parse(urlopen(URL2))
                except:
                        raise SystemExit('GetEncoderList failed, is the backend running?')
                for element2 in response.findall('Encoders/Encoder'):
                        if element2.findtext('Id') == element1.findtext('CardId'):
                                sys.exit(int(element2.findtext('State')))
                                break 
                break
sys.exit(-1)
