xml to integer

[kendias]

my question here:

I am trying the foll. python script to get sensor values from my smart phone so as to do calcs on these values. Hence, I need to convert from xml format to integer or float. Not sure how.

import socket, traceback, string
from sys import stderr

host = ''
port = 5555
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
s.bind((host, port))

# print one blank line
print 

while 1:
   try:
       message, address = s.recvfrom(8192)
#        print message

# split records using comma as delimiter (data are streamed in CSV format)
       data = message.split( "," )

# convert to flaot for plotting purposes
       t = data[0]
       sensorID = int(data[1])
       if sensorID==3:     # sensor ID for the eccelerometer
           ax, ay, az = data[2], data[3], data[4]
