View source for User:Eleanorg/Thematic1.1/Get Ship Position 2 - Regex

Grabs ship's latitude and longitude position, and prints the longitude.

<source lang=python>
#!/usr/bin/env python
#-*- coding:utf-8 -*-

# grabs the most up-to-date lat & long using a regex, then prints the longitude

import urllib2, re

page = urllib2.urlopen("http://www.marinetraffic.com/ais/shipdetails.aspx?mmsi=235080274&header=true").read()

for m in re.findall(r"(\d+\.\d+) ?˚ ?/ ?(\d+\.\d+) ?˚", page):
    print m[1]
# matches in captured () are stored in a list; longitude is at index 1 (second item in list)
</source>

This version does the same, but assigns the longitude to a variable instead of printing it:

<source lang=python>
#!/usr/bin/env python
#-*- coding:utf-8 -*-

# grabs the most up-to-date lat & long using a regex, then prints the longitude

import urllib2, re

page = urllib2.urlopen("http://www.marinetraffic.com/ais/shipdetails.aspx?mmsi=235080274&header=true").read()

for m in re.findall(r"(\d+\.\d+) ?˚ ?/ ?(\d+\.\d+) ?˚", page):
    longitude = m[1]
