jsp解析xml代碼的簡單介紹

用JSP解析XML

在後面用DOM取好後返回給前台jsp頁面顯示

import java.io.UnsupportedEncodingException;

import java.net.URLDecoder;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import org.w3c.dom.NodeList;

public class Baidu {

public static void main(String[] args) throws Exception {

ListString list = display();

MapString, String map = run(list);

for (int i = 0; i list.size(); i++) {

System.out.println(list.get(i) + “–” +map.get(list.get(i)));

}

}

private static String path;

static {

path = Baidu.class.getResource(“/test.xml”).getPath();

try {

path = URLDecoder.decode(path, “utf-8”);

} catch (UnsupportedEncodingException e) {

throw new RuntimeException(e);

}

}

// 得到normativeField中每項的值

public static ListString display() throws Exception{

Document doc = getDocument(path);

NodeList list = doc.getElementsByTagName(“normativeField”);

ListString normativeFieldList = new ArrayListString();

// 得到normativeField中每項的值加到normativeFieldList集合里

for (int i = 0; i list.getLength(); i++) {

normativeFieldList.add(list.item(i).getTextContent());

}

return normativeFieldList;

}

public static MapString, String run(ListString list) throws Exception {

MapString, String map = new HashMapString, String();

Document doc = getDocument(path);

for (int i = 0; i list.size(); i++) {

NodeList nodeListlist = doc.getElementsByTagName(list.get(i));

Element e = (Element) nodeListlist.item(0);

String value = e.getAttribute(“value”);

map.put(list.get(i), value);

}

return map;

}

public static Document getDocument(String path) throws Exception {

Document doc = DocumentBuilderFactory.newInstance()

.newDocumentBuilder().parse(path);

return doc;

}

}

控制台：

ID–eye1.id

xingming–eye1.name

xingbie–eye1.sex

nianling–eye1.age

shili–eye2.eyelight

shengao–eye2.high

tizhong–eye2.wealth

guomin–

gongfeizifei–eye1.pay

lianxifangshi–eye1.telephonenumber

bingli–eye1.content1

test.xml要在工程根目錄下：

?xml version=”1.0″ encoding=”UTF-8″?

JSP解析XML文件

把你的xml文檔貼出來看下。。。是不是你的nodelist就沒取到東西？

緊急求救！！！在jsp中解析xml時，代碼出現錯誤，請問我應該導入哪些jar包，能使程序正常，截圖如下

我可以幫你解決，我昨天剛把這個實現了。你留QQ給我。我加你。然後我把jar 給你。你自己複製進去。然後引入一下就可以了

JSP中能用javascript解析xml嗎？（我知道可以直接用java解析） 為什麼我做的時候老是說缺少對象？

IE下可以直接使用LoadXML方法解析XML字元串,而在FF下則要使用DOMParser 對象的parseFromString() 方法即

var oParser=new DOMParser();

xmlDoc=oParser.parseFromString(xmlStr,”text/xml”);

var document_xml=new ActiveXObject(“Microsoft.XMLDOM”);

document_xml.loadXML(XML);

var name=document_xml.getElementsByTagName(“vcOne”);

var value=document_xml.getElementsByTagName(“vcAction “);

var str1=name(0).firstChild.nodeValue;

一些關鍵的步驟 這樣你應該能完成剩下的全部吧

如果對您有幫助，請記得採納為滿意答案，謝謝！祝您生活愉快！
