xml to integer

[snippsat]

My question is - I want to use these readings to control a robot, do I have to convert this into another format and do the calcs or can I use as is.

Use a parer for XML data eg BeautifulSoup.
Here a demo,i insert regex to find all() to get all numbered Accelerometer1 2 3
Then loop over and convert to float()

from bs4 import BeautifulSoup
import re

xml ='''\
<Node Id>node12</Node Id>
<GPS>
  <Latitude>1.123123</Latitude>
  <Longitude>234.1231231</Longitude>
  <Accuracy>40.0</Accuracy>
</GPS>
<Accelerometer>
  <Accelerometer1>0.38444442222</Accelerometer1>
  <Accelerometer2>0.03799999939</Accelerometer2>
  <Accelerometer3>9.19400000331</Accelerometer3>
</Accelerometer>
<TimeStamp>1370354489083</TimeStamp>'''

soup = BeautifulSoup(xml, 'html.parser')
acc_meter = soup.find_all(re.compile("meter\d"))
for value in acc_meter:
    print(float(value.text))

Output:
0.38444442222
0.03799999939
9.19400000331
