jsp中解析dom不推荐，建议在后台用DOM取好后返回给前台jsp页面显示：
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 {
List list = display();
Map 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中每项的值
public static List display() throws Exception{
Document doc = getDocument(path);
NodeList list = doc.getElementsByTagName("normativeField");
List normativeFieldList = new ArrayList();
// 得到normativeField中每项的值加到normativeFieldList集合里
for (int i = 0; i < list.getLength(); i++) {
normativeFieldList.add(list.item(i).getTextContent());
}
return normativeFieldList;
}

public static Map run(List list) throws Exception {
Map map = new HashMap();
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要在工程根目录下：

relation

ID
xingming
xingbie
nianling
shili
shengao
tizhong
guomin
gongfeizifei
lianxifangshi
bingli

回答2：

SAXReader reader = new SAXReader();// 实例化解析器
File file = new File("路径");
Document doc = reader.read(file);
Element root = doc.getRootElement();// 得到根节点

List childList = root.elements(); //获取所有子节点

Element rsElement = root.element("rs");//获取rs节点

//获取子节点属性名、值
List attrList = root.attributes();
for (int i = 0; i < attrList.size(); i++) {
Attribute item = (Attribute)attrList.get(i);
System.out.println(item.getName() + "=" + item.getValue());
}

回答3：

SAXReader reader = new SAXReader();// 实例化解析器

File file = new File("路径");
Document doc = reader.read(file);

Element root = doc.getRootElement();// 得到根节点

其他的，自己去参考吧，不是太难，相信你可以的！
