You have to replace URL with the one that corresponds to your location.

Code:

require('socket.http')

forecast = {}

function parsetag(parser, tag, attributes)
 if tag == 'time' then
   table.insert(forecast, {})
 elseif tag == 'symbol' then
   forecast[ #forecast ].symbol = attributes.name
 elseif tag == 'precipitation' then
   forecast[ #forecast ].precipitation = attributes.value
 elseif tag == 'windDirection' then
   forecast[ #forecast ].wind_direction = attributes.code
 elseif tag == 'windSpeed' then
   forecast[ #forecast ].wind_speed = attributes.mps
 elseif tag == 'temperature' then
   forecast[ #forecast ].temperature = attributes.value
 elseif tag == 'pressure' then
   forecast[ #forecast ].pressure = attributes.value
 end
end

url = 'http://www.yr.no/place/United_Kingdom/England/London/varsel.xml'
data, err = socket.http.request(url)

if data then
 require('lxp').new({
   StartElement = parsetag
 }):parse(data)

 log(forecast)
else
 alert('Fetch failed: ' .. tostring(err))
end
