mud程序及内附的dom4j解析xml源代码

嗯断断续续弄了有两个月吧。先给个最简版本（做多用户多房间聊天室还是很好用的）。

如果未安装java虚拟机，需先到：http://www.java.com/zh_CN/download/manual.jsp下载。

选择：Windows（脱机安装），16兆的那个。这儿有个直接下载地址：http://jdl.sun.com/webapps/download/AutoDL?BundleId=10343

装好这个之后，分别下载：

http://www.foryears.com/mudserver.rar  mud服务器端

http://www.foryears.com/mudclient.rar  mud客户端

里面配有简要的说明。

附程序用到的dom4j解析xml：

import java.util.*;
import java.io.File;

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.DocumentException;
import org.dom4j.io.SAXReader;
import org.dom4j.Node;
import org.dom4j.DocumentHelper;
import org.dom4j.Attribute;

public class Dom4jParseXml {
    //通过xml文件名得到DOM
    public Document getDocument(String xmlFileName) throws DocumentException {
        SAXReader reader = new SAXReader();
        Document d = reader.read(new File(xmlFileName));
        return d;
    }
    //重载，通过xml文件内容得到DOM
    public Document getDocument(String xmlContent, boolean b) throws
            DocumentException {
        Document d = DocumentHelper.parseText(xmlContent);
        return d;
    }

    //输出字符串
    public String transformDOM(Document d) {
        String xmlContent = "";
        xmlContent = d.asXML();
        return xmlContent;
    }

    //得到节点
    public Element getNode(Document d, String elePath, String eleValue) {
        Element ele = null;
        List l = d.selectNodes(elePath);
        Iterator iter = l.iterator();
        while (iter.hasNext()) {
            Element tmp = (Element) iter.next();
            if (tmp.getText().equals(eleValue)) {
                ele = tmp;
            }
        }
        return ele;
    }
    //重载，得到节点
    public Element getNode(Document d, String eleName) {
        Element ele = (Element) d.selectSingleNode(eleName);
        return ele;
    }

    //增加节点
    public void addNode(Element parentEle, String eleName, String eleValue) {
        Element newEle = parentEle.addElement(eleName);
        newEle.setText(eleValue);
    }

    //增加属性节点
    public void addAttribute(Element ele, String attributeName,
                             String attributeValue) {
        ele.addAttribute(attributeName, attributeValue);
    }

    //删除节点
    public void removeNode(Element parentEle, String eleName, String eleValue) {
        Iterator iter = parentEle.elementIterator();
        Element delEle = null;
        while (iter.hasNext()) {
            Element tmp = (Element) iter.next();
            if (tmp.getName().equals(eleName) && tmp.getText().equals(eleValue)) {
                delEle = tmp;
            }
        }
        if (delEle != null) {
            parentEle.remove(delEle);
        }
    }

    //删除属性
    public void removeAttr(Element ele, String attributeName) {
        Attribute att = ele.attribute(attributeName);
        ele.remove(att);
    }

    //修改节点值
    public void setNodeText(Element ele, String newValue) {
        ele.setText(newValue);
    }

    //修改属性值
    public void setAttribute(Element ele, String attributeName,
                             String attributeValue) {
        Attribute att = ele.attribute(attributeName);
        att.setText(attributeValue);
    }
}
