jsp中读取xml文件中内容的方法,案例如下:
1、XML文件
<?xml version="1.0" encoding="GB2312" ?><!-- 个人履历表-->
<resume>
<person id="01">
<name>张三</name>
<birthday>03/24/1975</birthday>
<phone>1111-1111</phone>
<address>大连</address>
</person>
<person id="02">
<name>李四</name>
<birthday>9/26/1978</birthday>
<phone>2222-2222</phone>
<address>南京</address>
</person>
<person id="03">
<name>王五</name>
<birthday>11/09/1979</birthday>
<phone>3333-3333</phone>
<address>武汉</address>
</person>
<person id="04">
<name>赵六</name>
<birthday>6/04/1973</birthday>
<phone>4444-4444</phone>
<address>青岛</address>
</person>
<person id="05">
<name>陈七</name>
<birthday>12/19/1977</birthday>
<phone>5555-5555</phone>
<address>上海</address>
</person>
</resume>
2、MyDOMBean.java
package testimport org.xml.sax.*
import javax.xml.parsers.*
import org.w3c.dom.*
import java.io.*
public class MyDOMBean implements java.io.Serializable ...{
private static String xmlStr=""
private static final String PATH="file:///"
public MyDOMBean() ...{
}
public String getString()...{
return xmlStr
}
public static Document getDocument(String filename) throws Exception ...{
xmlStr=""
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance()
// 设定解析的叁数
dbf.setIgnoringComments(true)
dbf.setIgnoringElementContentWhitespace(true)
DocumentBuilder db = dbf.newDocumentBuilder()
//导入XML文件
Document doc = db.parse(PATH+filename)
return doc
}
public void traverseTree(Node node) throws Exception ...{
if(node == null) ...{
return
}
int type = node.getNodeType()
switch (type) ...{
case Node.DOCUMENT_NODE: ...{
xmlStr+="<tr>"
traverseTree(((Document)node).getDocumentElement())
break
}
// *** 作XML元素节点
case Node.ELEMENT_NODE: ...{
String elementName = node.getNodeName()
if(elementName.equals("person")) ...{
xmlStr+="</tr><tr>"
}
NodeList childNodes =node.getChildNodes()
if(childNodes != null) ...{
int length = childNodes.getLength()
for (int loopIndex = 0 loopIndex <
length loopIndex++)
...{
traverseTree(childNodes.item(loopIndex))
}
}
break
}
// *** 作XML文本节点
case Node.TEXT_NODE: ...{
String data = node.getNodeValue().trim()
if((data.indexOf(" ") <0) && (data.length()> 0)) ...{
xmlStr+="<td>"+data+"</td>"
}
}
}
}
}
3、jsp文件
<html><head>
<title>使用DOM解析器</title>
</head>
<%...@ page import="org.w3c.dom.*"%>
<%...@ page contentType="text/htmlcharset=GB2312" %>
<body bgcolor="#CFF1E1">
<center>
<h2>个人履历表(DOM版)</h2>
<table border="1" width="80%">
<tr>
<td>姓名</td>
<td>出生年月</td>
<td>电话号码</td>
<td>居住地</td>
</tr>
<jsp:useBean id="domparser" class="test.MyDOMBean" />
<%...
Document doc = domparser.getDocument(request.getRealPath("/") + "08_02.xml")
domparser.traverseTree(doc)
out.print(domparser.getString())
%>
</body>
</html>
你去查下<xml>这个标签的用法,下面是个例子<body>
<xml id="tree">
${xml信息}//你可以先把你的XML组织一下放到request然后通过这种方式EL方式放这
</xml>
</body>
<script language="JavaScript">
var xmlElement = window.document.getElementById("tree")
var root = xmlElement.XMLDocument.documentElement
//root就是和jdom解析XML一样就是根节点,以后和JDOM的 *** 作也很像
</script>
