Question

我正在尝试在RSS feed中获取远程PHP array内容并在其上执行一些操作。我正在使用simplexml_load_file将RSS转换为Array

e.g。

<?php
$raw_array = simplexml_load_file('https://kickass.to/new/rss/');
print_r($raw_array);
?>

给出输出

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [version] => 2.0
        )

    [channel] => SimpleXMLElement Object
        (
            [title] => Latest New Torrents RSS Feed - KickassTorrents
            [link] => http://kat.cr/
            [description] => Latest New Torrents RSS Feed
            [item] => Array
                (
                    [0] => SimpleXMLElement Object
                        (
                            [title] => title
                            [category] => category
                            [author] => http://kat.cr/user/author/
                            [link] => http://kat.cr/link.html
                            [guid] => http://kat.cr/link.html
                            [pubDate] => Mon, 18 May 2015 16:02:48 +0000
                            [enclosure] => SimpleXMLElement Object
                                (
                                    [@attributes] => Array
                                        (
                                            [url] => http://torcache.net/torrent/hash.torrent
                                            [length] => 83475908
                                            [type] => application/x-bittorrent
                                        )

                                )

                        )

但是当我直接进入RSS FEED并查看源代码时，会显示。

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:torrent="http://xmlns.ezrss.it/0.1/">
<channel>
    <title>Latest New Torrents RSS Feed - KickassTorrents</title>
    <link>http://kat.cr/</link>
    <description>Latest New Torrents RSS Feed</description>
    <item>
        <title>titletitletitle</title>

        <category>category- Video</category>
      <author>http://kat.cr/user/author/</author>        <link>http://kat.cr/link.html</link>
        <guid>http://kat.cr/guid.html</guid>
        <pubDate>Mon, 18 May 2015 15:36:42 +0000</pubDate>
        <torrent:contentLength>125153743</torrent:contentLength>
        <torrent:infoHash>212E859FB1BAFEA38BAB91BF3D94BB0DBB0ABFE4</torrent:infoHash>
        <torrent:magnetURI><![CDATA[magnet:?xt=urn:btih:212E859FB1BAFEA38BAB91BF3D94BB0DBB0ABFE4&dn=titletitle=udp%3A%2F%2Fopen.demonii.com%3A1337%2Fannounce]]></torrent:magnetURI>
        <torrent:seeds>0</torrent:seeds>
        <torrent:peers>0</torrent:peers>
        <torrent:verified>1</torrent:verified>
        <torrent:fileName>fileName.torrent</torrent:fileName>
        <enclosure url="http://torcache.net/torrent/212E859FB1BAFEA38BAB91BF3D94BB0DBB0ABFE4.torrent?title=[kat.cr]the.art.of.cocksucking.pir.te" length="125153743" type="application/x-bittorrent" />
    </item>

所以当我使用simplexml_load_file并不是所有子项/元素都被解析/获取时，它会丢失这些项目

        <torrent:contentLength>125153743</torrent:contentLength>
        <torrent:infoHash>212E859FB1BAFEA38BAB91BF3D94BB0DBB0ABFE4</torrent:infoHash>
        <torrent:magnetURI><![CDATA[magnet:?xt=urn:btih:212E859FB1BAFEA38BAB91BF3D94BB0DBB0ABFE4&dn=titletitle=udp%3A%2F%2Fopen.demonii.com%3A1337%2Fannounce]]></torrent:magnetURI>
        <torrent:seeds>0</torrent:seeds>
        <torrent:peers>0</torrent:peers>
        <torrent:verified>1</torrent:verified>
        <torrent:fileName>fileName.torrent</torrent:fileName>
<torrent:fileName>wwe.payback.2015.ppv.hdtv.x264.champions.rarbg.torrent</torrent:fileName>

我怎样才能从这些元素中获取值？

参考：Parsing a XML file using simplexml_load_file return empty object

我已经通过指定命名空间从上面的url尝试了这个方法。

<?php
$raw_array = simplexml_load_file('https://kickass.to/new/rss/', null, null, 'torrent', true);
print_r($raw_array);
?>

但它给出了空对象

SimpleXMLElement Object
(
)

那么如何从这个RSS FEED中获取所有元素，我可以想到其他方式是使用PHP curl获取feed并使用preg_match来查找标签及其内部值，但这将是难看的修复。

为什么simplexml_load_file没有解析/获取所有子项？
