1.接口內(nèi)容如下：
<?xml version="1.0" encoding="UTF-8"?>
<users>
<user>
<id>1</id>
<firstname>Song</firstname>
<lastname>Thinking</lastname>
<password>songlipeng</password>
</user>
<user>
<id>2</id>
<firstname>Zheng</firstname>
<lastname>Quanling</lastname>
<password>zhengquanling</password>
</user>
</users>
2.解析的JSP代碼如下：
<%@ page language="java" import="java.util.*,javax.xml.parsers.*,java.sql.*" pageEncoding="UTF-8"%>
<%@ page import="java.io.*,javax.xml.*,org.w3c.dom.*" %>
<%
//建立解析工廠
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setIgnoringElementContentWhitespace(true); //忽略元素內(nèi)容中的空格
//創(chuàng)建解析器
DocumentBuilder db = dbf.newDocumentBuilder();
//得到解析文件
//據(jù)說這樣寫可以讓
XML與JSP放在同一目錄哦
Document doc = db.parse("http://localhost:8080/MyProjects/webserver/users.xml"); //得到其他地方的接口目錄
doc.normalize();
//得到根元素
//Element root = doc.getDocumentElement();
//得到所有user元素
NodeList users = doc.getElementsByTagName("user");
NodeList usersIdNodeList= doc.getElementsByTagName("id");
NodeList usersNameNodeList= doc.getElementsByTagName("firstname");
NodeList usersPasswordNodeList=doc.getElementsByTagName("lastname");
NodeList usersTrueNameNodeList=doc.getElementsByTagName("password");
%>
<table>
<thead>
<tr>
<th>ID</th>
<th>firstName</th>
<th>lastName</th>
<th>password</th>
</tr>
</thead>
<%
Node userNode = null;
for (int i = 0; i < users.getLength(); i++) {
//Element user = (Element) users.item(i);
%>
<tr>
<td><%=usersIdNodeList.item(i).getFirstChild().getNodeValue()%></td>
<td><%=usersNameNodeList.item(i).getFirstChild().getNodeValue()%></td>
<td><%=usersPasswordNodeList.item(i).getFirstChild().getNodeValue()%></td>
<td><%=usersTrueNameNodeList.item(i).getFirstChild().getNodeValue()%></td>
<%
}
%>
</tr>
</table>
<!--只提取XML中的ID數(shù)據(jù)信息-->
<div>
<%
for(int i=0;i<usersIdNodeList.getLength();i++){
out.println("<b>"+usersIdNodeList.item(i).getFirstChild().getNodeValue()+"</b>");
}
%>
</div>
