Weather Data Available in XML

wombatmobile writes "Wired reports the National Oceanic and Atmospheric Administration this week began providing weather data in an open access XML format. Previously, the data was technically available to the public, but in a format that's not easily deciphered. How will the free and easy availability of valuable data like this in XML affect the development of the web? One example is Tom Groves SVG weather. This type of visualization of XML data is about to fall within easy reach with nothing more than a text editor required as an authoring tool. From March 2005 SVG becomes part of the standard Mozilla/FireFox build. As an example of how web standards are supposed to work, what more could you hope to find?" We mentioned the policy change a few days ago.

Click on a city in your area on this site: http://www.timeanddate.com/worldclock/custom.html? continent=namerica The page for each city lists the coordinates.

weather.com been doing this for a while

I set up a little script a long time ago to get weather data from an XML feed from the weather channel for our office webcam. It's free and was really easy to use...

http://www.weather.com/services/xmloap.html?

#!/usr/local/bin/perl -w
require LWP::UserAgent;
use XML::DOM;
use CGI qw(:standard);
# first, get the XML feed
my $ua = LWP::UserAgent->new(env_proxy => 1, keep_alive => 1, timeout => 30);
my $base_url="http://xoap.weather.com/weather/local/6 0143?cc=*&prod=xoap";
my $par="&par=[removed]";
my $key="&key=[sign up to get one]";
$response = $ua->get("$base_url$par$key");
die "Error while getting ", $response->request->uri,
" -- ", $response->status_line, "\nAborting"
unless $response->is_success;
my %weather = %$response;
# then, parse out the crap we want
my $parser = XML::DOM::Parser->new();
foreach(keys %weather){
$xmldoc = $parser->parse($weather{$_}) if(/content/);
}
foreach my $cur_cond ($xmldoc->getElementsByTagName('cc')){
$curr_cond{'lastup'} = $cur_cond->
getElementsByTagName('lsup')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'obsvst'} = $cur_cond->
getElementsByTagName('obst')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'temp'} = cur_cond->
getElementsByTagName('tmp')->item(0)->
&nb s p; getFirstChild->getNodeValue;
$curr_cond{'chill'} = $cur_cond->
getElementsByTagName('flik')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'text'} = $cur_cond->
getElementsByTagName('t')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'icon'} = cur_cond->
getElementsByTagName('icon')->item(0)->
getFirstChild->getNodeValue;
}
print header;
print start_html("nice little cgi page to display the time/weather");
print <<EOF;

sorry about the atrocious formating - slashcode made me take out whitespace (what is the fricking point of an ecode tag supported if you can't post a small snippet like this without removing all the whitespace!?)
