我怎样才能获得标题数组，博客链接<link rel="alternate" href="http://www.website.com/detail/2688327:BlogPost:1569917"/>，作者详细信息如name和uri（个人资料链接）以及使用php的摘要？

查看simplexml，xpath http://php.net/manual/en/book.simplexml.php

   $file = 'url or file name';
    $xml = simplexml_load_file('$file');
    $list= $xml->xpath("/entry"); // root/entry ...
    print $list[0]->id; 
    #var_dump($list);
