可以获取天气信息,不过天气是文字形式的!
 

------------------------regex-------------------------
function get_weather(con)
	local s = "<current_conditions>.*<\/forecast_conditions>"
	local i ,j = string.sub(con, string.find(con,s)) 
	local s = "\"[a-z0-9A-Z%s:%%]*\""  
	local info
	for word in string.gmatch(i, s) do 
			info = tostring(info).."\t"..tostring(word)  
	end
	local i, j = string.gsub(info, "\"","")
	local l = split(i,"\t")
	return l
end

------------------------split-------------------------
function split(string, spt)
	local find_index = 1
	local spt_index = 1
	local spt_arr = {}
	while true do
		local find_end = string.find(string, spt, find_index)
		if not find_end then
			spt_arr[spt_index] = string.sub(string, find_index, string.len(string))
			break
		end
		spt_arr[spt_index] = string.sub(string, find_index, find_end - 1)
		find_index = find_end + string.len(spt)
		spt_index = spt_index + 1
	end
	return spt_arr
end
