最近项目需要用到 城市的地址信息，但从网上下载的xml数据没有几个是最新的地址信息.....数据太老，导致有些地区不全。所以才想到天气预报官网特定有最新最全的数据。贴出代码，希望能给有同样困惑的朋友，减少一些时间。

	/**
	 * @param var  城市名称
	 * @return	string数组，0表示邮编	1表示区号
	 */
	@SuppressWarnings("deprecation")
	private String[] getZipCode(String var) {
		String[] code = new String[2];
		String zipCode_S = "邮编：";
		String zipCode_E = " ";
		String qhCode_S = "区号：";
		String qhCode_E = "</td>";
		String encode = URLEncoder.encode(var);
		try {
			URL url = new URL("http://www.ip138.com/post/search.asp?area="
					+ encode + "&action=area2zone");
			BufferedReader br = new BufferedReader(new InputStreamReader(
					url.openStream(), "GBK"));
			for (String line; (line = br.readLine()) != null;) {
				int zipNum = line.indexOf(zipCode_S);
				if (zipNum > 1) {
					String str = line.substring(zipNum + zipCode_S.length());
					str = str.substring(0, str.indexOf(zipCode_E));
					code[0] = str;
				}
				int qhNum = line.indexOf(qhCode_S);
				if(qhNum > 1)
				{
					String str = line.substring(qhNum + qhCode_S.length());
					str = str.substring(0, str.indexOf(qhCode_E));
					code[1] = str;
					break;
				}
			}
		} catch (Exception e) {
			System.out.println(var +"\t错误"+e.toString());
		}
		return code;
	}

小巧抓取(省、市(区号\邮编)、县)数据
