清单 1. 示例 XML 文档（catalog.xml） 
<?xml version="1.0" encoding="UTF-8"?> 
<catalog> 
<!--An XML Catalog--> 
<?target instruction?>
  <journal title="XML Zone" 
                  publisher="IBM developerWorks"> 
<article level="Intermediate" date="December-2001">
 <title>Java configuration with XML Schema</title> 
 <author> 
     <firstname>Marcello</firstname> 
     <lastname>Vitaletti</lastname> 
 </author>
  </article>
  </journal> 
</catalog>
 然后使用同一个解析器修改 catalog.xml，清单 2 是修改后的 XML 文档，catalog-modified.xml。清单 2. 修改后的 XML 文档（catalog-modified.xml） 
<?xml version="1.0" encoding="UTF-8"?> 
<catalog> 
<!--An XML catalog--> 
<?target instruction?>
  <journal title="XML Zone"
                   publisher="IBM developerWorks"> 
<article level="Introductory" date="October-2002">
 <title>Create flexible and extensible XML schemas</title> 
 <author> 
     <firstname>Ayesha</firstname> 
     <lastname>Malik</lastname> 
 </author> 
  </article>
  </journal> 
</catalog>
 
清单 3 所示的例子程序 XmlDom4J.java 用于创建 XML 文档 catalog.xml。清单 3. 生成 XML 文档 catalog.xml 的程序（XmlDom4J.java） 
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.XMLWriter;

     Element catalogElement = document.addElement("catalog");
     catalogElement.addComment("An XML Catalog");
     catalogElement.addProcessingInstruction("target","text");
     Element journalElement =  catalogElement.addElement("journal");
     journalElement.addAttribute("title", "XML Zone");
     journalElement.addAttribute("publisher", "IBM developerWorks");
     Element articleElement=journalElement.addElement("article");
     articleElement.addAttribute("level", "Intermediate");
     articleElement.addAttribute("date", "December-2001");

     titleElement.setText("Java configuration with XML Schema");
     Element authorElement=articleElement.addElement("author");
     Element  firstNameElement=authorElement.addElement("firstname");
     firstNameElement.setText("Marcello");
     Element lastNameElement=authorElement.addElement("lastname");
     lastNameElement.setText("Vitaletti");
     document.addDocType("catalog",
                           null,"file://c:/Dtds/catalog.dtd");
    try{
    XMLWriter output = new XMLWriter(
            new FileWriter( new File("c:/catalog/catalog.xml") ));
        output.write( document );
        output.close();
        }
     catch(IOException e){System.out.println(e.getMessage());}
}
public static void main(String[] argv){
XmlDom4J dom4j=new XmlDom4J();
dom4j.generateDocument();
}}
 
清单 4 所示的示例程序 Dom4JParser.java 用于把 catalog.xml 文档修改成 catalog-modified.xml 文档。清单 4. 用于修改 catalog.xml 的程序（Dom4Jparser.java）

Answer 2

你给的例子是 创建一个xml 意思是可以根据一个bean 创建一个xml 还有修改的例子。那我xml创建好以后 的解析用dom4j怎么做呢？谢谢 :-) 在麻烦下。

Answer 3

这是我以前回答别人问题的程序，（http://topic.csdn.net/u/20080611/08/cb0894cc-e3dd-4600-95d9-147af5ac616d.html）
也是解析XML文档的，希望对你有用[javacode]
我给你一个自己用LOG4J做的 
package dom4j; import java.util.Iterator; import org.dom4j.Document; 
import org.dom4j.DocumentException; 
import org.dom4j.Element; 
import org.dom4j.io.SAXReader; public class testCSDN { 
public static String DOM_FILE_PATH = new String("testCSDN.xml"); 
public static void main(String[] args) throws DocumentException { 
new testCSDN().parseXML(DOM_FILE_PATH); 
} 
public void parseXML(String DOM_FILE_PATH) throws DocumentException{ 
SAXReader reader = new SAXReader(); 
Document document = reader.read(DOM_FILE_PATH); 
Element root = document.getRootElement(); Element foo = null; 
Element elm = root.element("resourceitem"); 
Iterator <Element> it = root.elementIterator("resourceitem"); while (it.hasNext()) { 
StringBuffer temp = new StringBuffer(); 
foo = it.next(); 
temp.append(foo.elementText("title") + " "); 
temp.append(foo.elementText("keywords") + " "); 
temp.append(foo.elementText("kind") + " "); 
temp.append(foo.elementText("describe") + " "); 
temp.append(foo.elementText("date") + " "); 
temp.append(foo.elementText("url") + " "); 
temp.append(foo.elementText("author") + " "); 
temp.append(foo.elementText("publisher")); 
System.out.println(temp.toString()); 
} 
} 
} 
运行结果:

Answer 4

我写好一个XML例子,用DOM4J解析时出现一个错误:The type org.jaxen.VariableContext cannot be resolved. It is indirectly referenced from required .class files
代码:XMLTableModel model=new XMLTableModel(definition,document);
错误是在这个代码上出现的,哪位高手麻烦给解释下
        

Answer 5

用二楼的代码 生成xml时候没有问题但是解析xml的时候 报下边的问题：c Nested exception: c
我估计是这段代码。
 Document document = saxReader.read(new File("d://catalog.xml"));

网上有很多例子，而且都是写好的不用调试就可以了到google上去找吧，比你在这里等来的快
