SAX PULL解析

SAX,本地解析：

 

try {
        	SAX(getAssets().open("data.xml"));
        } catch (Exception e) {
			e.printStackTrace();
     }

			XMLAdressInfo xmlAdress = new XMLAdressInfo();
			xReader.setContentHandler(xmlAdress);

			xReader.parse(new InputSource(input));
			
			//获得所有的数据
			hashMap = xmlAdress.getData();
			//获得省市对应的数据
			provinceCity = xmlAdress.getCityData();
			
			Log.d("dfdfd", ""+provinceCity.size());
		}
