首先准备数据源，数据源采用数据库、XML、数组等都可以。下面以XML做例子。Contacts.xml文件如下： R88Linux联盟
<?xml version="1.0" encoding="gb2312" standalone="yes"?> <Contacts> <Contact> <Email>myaddress@mycompany.com</Email> <FirstName>E章</FirstName> <LastName>孟子</LastName> <Manager>0</Manager> </Contact> <Contact> <Email>youraddress@yourcompany.com</Email> <FirstName>宪会</FirstName> <LastName>孟</LastName> <Manager>1</Manager> </Contact> <Contact> <Email>mm@mmm.mm</Email> <FirstName>Lover</FirstName> <LastName>Net</LastName> <Manager>0</Manager> </Contact> <Contact> <Email>xxx@xxxx.xx</Email> <FirstName>NET开发者园地</FirstName> <LastName/> <Manager>0</Manager> </Contact> <Contact> <Email>hhh@hhh.hh</Email> <FirstName>XML开发者园地</FirstName> <LastName/> <Manager>1</Manager> </Contact> </Contacts> R88Linux联盟
