SAXReader sax=new SAXReader();
try {
doc=sax.read(new File("./src/com/lufeisong/dom4j/ch6.xml"));
} 
catch (DocumentException e) 
{
e.printStackTrace();
}
return doc;
}
public void list2XML()
{
Document doc=getDoc();
Element ele=doc.getRootElement();
List list=ele.selectNodes("雇员/工资");
for(int i=0;i<=list.size();i++)
{
//System.out.println(((Element)list.get(i)).getText());
System.out.println(((Element)list.get(i)).getText());
}
}
public static void main(String [] args)

------解决方案--------------------
for(int i=0;i<=list.size();i++)
改成for(int i=0;i<list.size();i++)
试试
