Question

我试图在php中创建RSS提要，我想从两个不同的链接中获取数据。澄清;我想从两个不同的网站获取数据，并将其显示为链接为我自己的链接。

现在我从两个不同的网站获取数据，但我无法同时显示两组数据。

这是我的代码，有人可以帮忙吗？

从网址获取q参数$ q = $ _ GET [＆＃34; q＆＃34;];

//find out which feed was selected 
if($q==" Tech") {  
 $xml=("http://----/myrssfeed.xml"); 
} elseif($q=="Herald") {  
 $xml=("http://******/top-stories.rss"); }
 $xmlDoc = new DOMDocument(); $xmlDoc->load($xml);


 //get elements from "<channel>"
 $channel=$xmlDoc->getElementsByTagName('channel')->item(0);
 $channel_title = $channel->getElementsByTagName('title')

 ->item(0)->childNodes->item(0)->nodeValue; $channel_link = $channel->getElementsByTagName('link')

 ->item(0)->childNodes->item(0)->nodeValue; $channel_desc = $channel->getElementsByTagName('description')

 ->item(0)->childNodes->item(0)->nodeValue;


 //output elements from "<channel>"
 echo("<p><a href='" . $channel_link. "'>" . $channel_title . "</a>"); 
 echo("<br>");
 echo($channel_desc . "</p>");

 //get and output "<item>" elements
 $x=$xmlDoc->getElementsByTagName('item'); 

for ($i=0; $i<=11; $i++) {  
 $item_title=$x->item($i)->getElementsByTagName('title')  

 ->item(0)->childNodes->item(0)->nodeValue;   $item_link=$x->item($i)->getElementsByTagName('link')  
 ->item(0)->childNodes->item(0)->nodeValue;   $item_desc=$x->item($i)->getElementsByTagName('description')  
 ->item(0)->childNodes->item(0)->nodeValue;   

 echo ("<p><a href='" . $item_link . "'>" . $item_title . "</a>");  
 echo ("<br>");   
 echo($item_desc . "</p>");
} ?>
