What does the specific specification information mean? We can easily know according to the content of the tag. Next, we write an rss.php to read this xml and obtain the above article:

$dom = simplexml_load_file("http://rss.sina.com.cn/news/world/focus15.xml");
//var_dump($dom);
?>

The example of RSS

foreach($dom->channel->item as $item)
{
print("

  print("");
  print($item->title);
  print("");
  print("
");
}
?>

Pay attention to this function: simplexml_load_file(); it can read both local xml files and xml on the network.

Run result:
