title: Parsing METAR webpage in python
body: <p>I need to use METAR weather information in a python script. I found <a href="http://pypi.python.org/pypi/metar/1.4.0" rel="nofollow">http://pypi.python.org/pypi/metar/1.4.0</a> which seems like it should work for what I need for current METARs. However, I also need to use archived weather information.</p>
  
  <p>I found Navlost.eu, which seems to work well for what I need. For example,
  <a href="http://www.navlost.eu/aero/metar/?icao=KBOS&amp;dt0=2010-07-14+02%3A00%3A00&amp;c=1&amp;rt=metar" rel="nofollow">http://www.navlost.eu/aero/metar/?icao=KBOS&amp;dt0=2010-07-14+02%3A00%3A00&amp;c=1&amp;rt=metar</a></p>
  
  <p>The python METAR module accesses a text file and parses that. How do I parse this webpage in a similar manner so that I am only grabbing the "KBOS 140154Z 15006KT 8SM -RA OVC034 23/22 A2994" text in this example?</p>
