应用xml完成rss定阅【XML教程】,xml，rss

RSS是一种网页内容团结花样，是XML的一种，一切的RSS文档都遵照XML1.0范例。

细致示例：

<span style="font-family:Microsoft YaHei;font-size:18px;"><?xml version = "1.0" encoding = "utf-8" ?>  
<rss version = "2.0" xmlns:wfw ="http://wellformedweb.org/CommentAPI/">  
       <channel>  
              <title>题目</title>  
              <link>链接地点</link>  
              <description>形貌</description>  
              <language>形貌言语</language>  
              <copyright>版本</copyright>  
              <pubdate>时候</pubdate>  
              <item>  
                     <title>日记题目</title>  
                  <link>日记的url接见地点</link>  
                     <author>日记的作者</author>  
                     <pubdate>日记的宣布时候</pubdate>  
                     <description>日记的内容</description>  
              </item>  
       </channel>  
</rss></span>

此时应当链接数据库，输出想要的效果。

Test.PHP

<span style="font-family:Microsoft YaHei;font-size:18px;"><?PHP  
       include("./conn.php");  
       class test{  
              public $title = '';  
              public $link = '';  
              public $description= '';  
              public $items = '';  
              public $template ='./test.xml';  
              public $dom = '';  
              public $rss = '';  
              public function__construct(){  
                     $this ->dom = new domDocument('1.0','utf-8');  
                     $this ->dom -> load($this -> template);  
                     $this ->rss = $this -> dom -> GetElementsByTagName('rss');  
              }  
              public functioncreateChannel(){  
                     $channel =$this -> dom -> createElement("channel");  
                     $channel-> appendChild($this -> createEle('title',$this -> title));  
                     $channel-> appendChild($this -> createEle('link',$this -> link));  
                     $channel-> appendChild($this -> createEle('description',$this ->description));  
                     $this ->rss -> appendChild($channel);  
                        
              }  
              public functioncreateEle($name,$value){  
                     $element =$this -> dom -> createElement($name);  
                     $text = $this-> dom -> createTextNode($value);  
                     $element-> appendChild($text);  
                     return$element;  
              }  
              protected functionadditem($list){  
                     foreach($listas $goods){  
                            $this-> rss -> appendChild($this-> createitem($goods));  
                     }  
              }  
              public functioncreateitem($arr){  
                     $item = $this-> dom -> createElement("item");  
                     foreach($arras $key => $value){  
                            $item-> appendChild($this -> createEle($key,$value));  
                     }  
                     return $item;  
              }  
                 
              public functiondisplay(){  
                     $this ->createChannel();  
                     $this ->additem($this -> items);  
                     echo $this-> dom -> savexml();  
              }  
       }  
       $sql = "select * fromstu";  
       $rs = mysql_query($sql);  
       while($row =mysql_fetch_assoc($rs)){  
              $list[] = $row;  
       }  
       $test = new test();  
       $test -> title = "测试题目";  
       $test -> link = "测试衔接";  
       $test -> description ="测试内容";  
       $test -> display();  
       $test -> items = $list;  
</span>
