Android使用SAX解析XML(5)

parse_handler.java文件：

package com.hzhi.my_sax;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class parse_handler extends DefaultHandler{

	private infor m_infor;
	private school m_c_school;
	private major m_c_major;

	public parse_handler(infor i){
		m_infor = i;
	}

	public void startElement(String uri, String localName, String name,
			Attributes attributes) throws SAXException{

		super.startElement(uri, localName, name, attributes);

		// 当前元素学院
		if (localName.equalsIgnoreCase(school.tag_name)){

			String school_name = attributes.getValue("Name");
			String code = attributes.getValue("Code");

			school m_school = new school(school_name, code);
			m_infor.add_school(m_school);
			// 记录当前的学院
			m_c_school = m_school;

		}
		// 当前元素有专业
		else if (localName.equalsIgnoreCase(major.tag_name)){

			String major_name = attributes.getValue("Name");
			String code = attributes.getValue("Code");

			major m_major = new major(major_name, code);
			m_c_school.add_major(m_major);
			// 记录当前的学院
			m_c_major = m_major;

		}
		// 当前元素有班级
		else if (localName.equalsIgnoreCase(clas.tag_name)){
			String clas_name = attributes.getValue("Name");
			String code = attributes.getValue("Code");

			//如果其从属的专业不为空则添加其专业的班级列表
			if(m_c_major != null) {
				clas m_clas = new clas(clas_name, code);
				m_c_major.add_clas(m_clas);
			}
		}

	}

}

该类的startElement()函数具体的完成了对XML文件的解析过程，并将解析结果放入变量m_infor中。
