程序代码片-类方法：用到jdom包
public void removeElement(String path,String catalog){
SAXBuilder sb = new SAXBuilder();
try
{
Document doc = sb.build(path);
Element root = doc.getRootElement();
Element subroot=root.getChild("entity");
Element content=subroot.getChild("contents");
List entities=content.getChildren("entity");
for(int j=0;j<entities.size();j++)
{
Element _element=(Element)entities.get(j);
if(_element.getChild("nick").getText().equals(catalog))
{
System.out.println(_element.getChild("nick").getText());
System.out.println(_element.getChild("description").getText());
content.removeContent(_element);
//_element.removeContent(_element);
}
}
Format format = Format.getCompactFormat();
format.setEncoding("UTF-8"); //设置xml文件的字符为UTF-8
format.setIndent(" "); //设置xml文件的缩进为4个空格
XMLOutputter xmlOutput = new XMLOutputter(format);
xmlOutput.output(root, new FileOutputStream(path));
}
catch(Exception e)
{
e.printStackTrace();
}
}

错误出现在： 1、content.removeContent(_element);
2、 //_element.removeContent(_element);
用第2种方法总达不到效果，搞了半天才更正了错误。
