用SAX方式解析XML，XML文件如下：
<?xml version=1.0 encoding=gb2312?> <person> <name>王小明</name> <college>信息学院</college> <telephone>6258113</telephone> <notes>男,1955年生,博士，95年调入海南大学</notes> </person> 事件回调类SAXHandler.java import java.io.*; import java.util.Hashtable; import org.xml.sax.*; public class SAXHandler extends HandlerBase { private Hashtable table = new Hashtable(); private String currentElement = null; private String currentValue = null; public void setTable(Hashtable table) { this.table = table; } public Hashtable getTable() { return table; } public void startElement(String tag, AttributeList attrs) throws SAXException { currentElement = tag; } public void characters(char[] ch, int start, int length) throws SAXException { currentValue = new String(ch, start, length); } public void endElement(String name) throws SAXException { if (currentElement.equals(name)) table.put(currentElement, currentValue); } } JSP内容显示源码,SaxXml.jsp: <HTML> <HEAD> <TITLE>剖析XML文件people.xml</TITLE> </HEAD> <BODY> <%@ page errorPage=ErrPage.jsp contentType=text/html;charset=GB2312 %> <%@ page import=java.io.* %> <%@ page import=java.util.Hashtable %> <%@ page import=org.w3c.dom.* %> <%@ page import=org.xml.sax.* %> <%@ page import=javax.xml.parsers.SAXParserFactory %> <%@ page import=javax.xml.parsers.SAXParser %> <%@ page import=SAXHandler %> <% File file = new File(c:\people.xml); FileReader reader = new FileReader(file); Parser parser; SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); SAXHandler handler = new SAXHandler(); sp.parse(new InputSource(reader), handler); Hashtable hashTable = handler.getTable(); out.println(<TABLE BORDER=2><CAPTION>教师信息表</CAPTION>); out.println(<TR><TD>姓名</TD> + <TD> + (String)hashTable.get(new String(name)) + </TD></TR>); out.println(<TR><TD>学院</TD> + <TD> + (String)hashTable.get(new String(college))+</TD></TR>); out.println(<TR><TD>电话</TD> + <TD> + (String)hashTable.get(new String(telephone)) + </TD></TR>); out.println(<TR><TD>备注</TD> + <TD> + (String)hashTable.get(new String(notes)) + </TD></TR>); out.println(</TABLE>); %> </BODY> </HTML> 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。
