獲取全國所有城市程式碼列表
方法一：
XML介面根節點： http://flash.weather.com.cn/wmaps/xml/china.xmlXML介面主要作用是遞迴獲取全國幾千個縣以上單位的城市程式碼，
如：江蘇的XML地址為：http://flash.weather.com.cn/wmaps/xml/shanghai.xml 蘇州的XML地址為：http://flash.weather.com.cn/wmaps/xml/jiangsu.xml
上面頁面獲得太倉city code：101190408
合成太倉天氣資訊地址：http://m.weather.com.cn/data/101190408.html
下面貼一段PHP程式碼實現的，通過XML介面根節點遞迴獲得全國幾千個縣以上城市cide code的程式碼，供參考(可直接在終端下執行）：
方法二：一次性獲取全國+國外主要城市，8763個城市列表資訊。URL：http://mobile.weather.com.cn/js/citylist.xml
