XML文件如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>@H_502_4@ @H_502_4@ <books>@H_502_4@ @H_502_4@ <book name="book1" num="1" > 出版于1991年 </book>@H_502_4@ <book name="book2" num="2" > 出版于1992年 </book>@H_502_4@ <book name="book3" num="3" > 出版于1993年 </book>@H_502_4@ <book name="book4" num="4" > 出版于1994年 </book>@H_502_4@ @H_502_4@ </books>
@H_502_4@
解析后的结果：
@H_502_4@
@H_502_4@
@H_502_4@
封装model来接收解析后的XML文件数据
