Question

Can anyone teach me how to extract the latitude and longitude values? How can I do that? 

url="https://api.projectnimbus.org/neaodataservice.svc/NowcastSet"
request = urllib2.Request(url)
request.add_header("accept", "*/*")
request.add_header('AccountKey', "OSJeROQjTg4v7Ec3kiecjw==")
request.add_header('UniqueUserID', "00000000000000000000000000000001")
result = urllib2.urlopen(request)
for key in result.readlines():
    print key

Maybe storing into dict, funct, for loop ?

I only need the values here, such as area, lat and long.

Solution

BeautifulSoup is your friend.

import urllib2
try:
    from bs4 import BeautifulStoneSoup #Using bs4
except ImportError:
    from BeautifulSoup import BeautifulStoneSoup #Using bs3

url="https://api.projectnimbus.org/neaodataservice.svc/NowcastSet"
request = urllib2.Request(url)
request.add_header("accept", "*/*")
request.add_header('AccountKey', "OSJeROQjTg4v7Ec3kiecjw==")
request.add_header('UniqueUserID', "00000000000000000000000000000001")
result = urllib2.urlopen(request)
xml_str = result.read()

soup = BeautifulStoneSoup(xml_str)

prop_list = []
for content in soup.findAll("m:properties")
    props = {}
    for prop in content.findChildren():
        props[prop.name[2:]] = prop.text
    prop_list.append(props)

print prop_list
