我在从itunes XML提要中获取信息时遇到了一些问题,您可以在此处查看:http://c3carlingford.org.au/podcast/C3CiTunesFeed.xml
我需要从每个内部<item>
标签中获取信息。其中一个例子如下:
<item>
<title>What to do when a viper bites you</title>
<itunes:subtitle/>
<itunes:summary/>
<!-- 4000 Characters Max ******** -->
<itunes:author>Ps. Phil Buechler</itunes:author>
<itunes:image href="http://www.c3carlingford.org.au/podcast/itunes_cover_art.jpg"/>
<enclosure url="http://www.ccccarlingford.org.au/podcast/C3C-20120722PM.mp3" length="14158931" type="audio/mpeg"/>
<guid isPermaLink="false">61bc701c-b374-40ea-bc36-6c1cdaae8042</guid>
<pubDate>Sun, 22 Jul 2012 19:30:00 +1100</pubDate>
<itunes:duration>40:01</itunes:duration>
<itunes:keywords>
Worship, Reach, Build, Holy Spirit, Worship, C3 Carlingford
</itunes:keywords>
</item>
现在我取得了一些成功我已经能够从这一切中获得标题:
<?php
$dom = new DOMDocument();
$dom->preserveWhiteSpace = false;
$dom->load('http://c3carlingford.org.au/podcast/C3CiTunesFeed.xml');
$items = $dom->getElementsByTagName('item');
foreach($items as $item){
$title = $item->getElementsByTagName('title')->item(0)->nodeValue;
echo $title . '<br />';
};
?>
但我似乎什么都拿不出来。。。我是这一切的新手!
所以我需要得到的包括:
<itunes:author>
值<enclosure>
标记的url属性值
有人能帮我把这两个价值观拿出来吗?
您可以使用DOMXPath
来做到这一点,并使您的生活更加轻松:
$doc = new DOMDocument();
$doc->preserveWhiteSpace = false;
$doc->loadXML( $xml); // $xml = file_get_contents( "http://www.c3carlingford.org.au/podcast/C3CiTunesFeed.xml")
// Initialize XPath
$xpath = new DOMXpath( $doc);
// Register the itunes namespace
$xpath->registerNamespace( 'itunes', 'http://www.itunes.com/dtds/podcast-1.0.dtd');
$items = $doc->getElementsByTagName('item');
foreach( $items as $item) {
$title = $xpath->query( 'title', $item)->item(0)->nodeValue;
$author = $xpath->query( 'itunes:author', $item)->item(0)->nodeValue;
$enclosure = $xpath->query( 'enclosure', $item)->item(0);
$url = $enclosure->attributes->getNamedItem('url')->value;
echo "$title - $author - $url'n";
}
你可以从演示中看到,这将输出:
What to do when a viper bites you - Ps. Phil Buechler - http://www.ccccarlingford.org.au/podcast/C3C-20120722PM.mp3
是的,您可以使用simplexml来完成。
这是示例代码:
<?php
$x = simplexml_load_file("http://c3carlingford.org.au/podcast/C3CiTunesFeed.xml");
foreach ($x->channel->item as $item) {
$otherNode = $item->children('http://www.itunes.com/dtds/podcast-1.0.dtd');
echo $item->title .'---'.$otherNode->author;
echo "'n";
}
?>
输出:
毒蛇咬你该怎么办。Phil Buechler
活水,让河水流过---Phil Buechler
上帝的呼召彼此宽恕AM&下午---下午。Richard Botta
上帝对福音传道者AM&PM---Rob Waugh
上帝的呼唤爱彼此AM&PM---Rob Waugh
希望得到帮助!
您可以使用simpleXML子级
$item->children('tunes',TRUE);
因此,您有一个数组,其中包含所有标签itunes:duration,itunes:subtitle。。。。
<?php
$x = simplexml_load_file("http://c3carlingford.org.au/podcast/C3CiTunesFeed.xml");
foreach ($x->channel->item as $item) {
$otherNode = $item->children('itunes', TRUE);
echo $otherNode->duration;
echo "'n";
echo $otherNode->author;
echo "'n";
echo $otherNode->subtitle;
echo "'n";
}
?>
