调用雅虎天气API

这两天一直在弄天气信息的问题，不知道为什么百度别人都写的超级复杂，看的头都大了，总算是写出来了。。。

 

我用的是SSH框架，所以直接就有dom4j的架包，如果没有可以下一个

String[] dictionaryStrings = { "龙卷风", "热带风暴", "飓风", "强雷阵雨",
		            "雷阵雨", "小雨加雪", "雨加冰雹", "雪加冰雹", "冰雨", "毛毛雨", "冻雨", "阵雨", "阵雨", "小雪",
		            "零星小雪", "高吹雪", "雪", "冰雹", "雨夹雪", "尘", "雾", "薄雾", "多烟的", "大风", "有风",
		            "寒冷", "阴天", "夜间阴天", "白天阴天", "夜间多云", "白天多云", "夜间清亮", "晴朗", "转晴",
		            "转晴", "雨夹冰雹", "热", "雷阵雨", "雷阵雨", "雷阵雨", "雷阵雨", "大雪", "阵雪", "大雪",
		            "多云", "雷", "阵雪", "雷雨" };
		URL url=null;
		try {
			url=new URL("http://weather.yahooapis.com/forecastrss?w=2502265&u=c");//w是城市的代码，u是温度单位
		} catch (MalformedURLException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		SAXReader saxReader = new SAXReader();
		List code=new ArrayList();
		try {   
		Document document = saxReader.read(url);   
		Element employees=document.getRootElement();   
		for(Iterator i = employees.elementIterator(); i.hasNext();){   
		Element employee = (Element) i.next();   
			for(Iterator j = employee.elementIterator(); j.hasNext();){   
			Element node=(Element) j.next();
			if(node.getName().equals("item")){
				for(Iterator k = node.elementIterator(); k.hasNext();){   
					Element val=(Element) k.next();   
					if(val.getName().equals("forecast")){
						code.add(val.attributeValue("code"));
					}
					} 
			}
			} 
		}   
		} catch (DocumentException e) {   
		System.out.println(e.getMessage());   
		}   
		System.out.println(code.get(0));
		int r=Integer.valueOf(code.get(0).toString());
		System.out.println(dictionaryStrings[r]);

多简单的东西啊！！！
