我有一个XML文档,如下所示:
<Data
xmlns="http://www.domain.com/schema/data"
xmlns:dmd="http://www.domain.com/schema/data-metadata"
>
<Something>...</Something>
</Data>
我正在使用PHP中的SimpleXML解析信息.我正在处理数组,我似乎遇到了命名空间的问题.
我的问题是:如何删除这些名称空间？我从XML文件中读取数据.
谢谢!
我正在阅读的XML看起来像这样:
<show id="8511">
<name>The Big Bang Theory</name>
<link>http://www.tvrage.com/The_Big_Bang_Theory</link>
<started>2007-09-24</started>
<country>USA</country>
<latestepisode>
<number>05x23</number>
<title>The Launch Acceleration</title>
</latestepisode>
</show>
要获得(例如)最新一集的数量,我会这样做:
$ep = $xml->latestepisode[0]->number;
这很好用.但是如何从中获取ID <show id="8511">呢？
我尝试过类似的东西:
$id = $xml->show;
$id = $xml->show[0];
但都没有效果.
更新
我的代码片段:
$url = "http://services.tvrage.com/feeds/episodeinfo.php?show=".$showName;
$result = file_get_contents($url);
$xml = new SimpleXMLElement($result);
//still doesnt work
$id = $xml->show->attributes()->id;
$ep = $xml->latestepisode[0]->number;
echo ($id);
大利.XML:
http://services.tvrage.com/feeds/episodeinfo.php?show=The.Big.Bang.Theory
这个:
$XML = new SimpleXMLElement("<foo />");
echo($XML->asXML());
...输出:
<?xml version="1.0"?>
<foo/>
但我也希望它输出编码:
<?xml version="1.0" encoding="UTF-8"?>
<foo/>
有没有办法告诉SimpleXMLElement包含<？xml？>标签的编码属性？除此之外:
$XML = new SimpleXMLElement("<?xml version='1.0' encoding='utf-8'?><foo />");
echo($XML->asXML());
哪个有效,但是必须手动指定版本和编码很烦人.
假设为了这个问题的目的,我不能使用DOMDocument.
我正在尝试解决如何迭代返回的SimpleXML对象.
我正在使用一个名为Tarzan AWS的工具包,它连接到Amazon Web Services(SimpleDB,S3,EC2等).我特意使用SimpleDB.
我可以将数据放入Amazon SimpleDB服务,我可以将其恢复.我只是不知道如何处理返回的SimpleXML对象.
Tarzan AWS文档说明了这一点:
查看响应以浏览响应的标题和正文.请注意,这是一个对象,而不是一个数组,并且正文是一个SimpleXML对象.
这是返回的SimpleXML对象的示例:
[body] => SimpleXMLElement Object
(
[QueryWithAttributesResult] => SimpleXMLElement Object
(
[Item] => Array
(
[0] => SimpleXMLElement Object
(
[Name] => message12413344443260
[Attribute] => Array
(
[0] => SimpleXMLElement Object
(
[Name] => active
[Value] => 1
)
[1] => SimpleXMLElement Object
(
[Name] => user
[Value] => john
)
[2] => SimpleXMLElement Object
(
[Name] => message
[Value] => This is a message.
)
[3] = … 我正在尝试从Flickr读取RSS提要,但它有一些不能被Simple XML(media:thumbnail,flickr:profile等等)读取的节点.
我怎么绕这个？当我查看DOM的文档时,我的头疼.所以我想避免它,因为我不想学习.
顺便说一句,我正试图获取缩略图.
我正在尝试从此youtube播放列表供稿中获取视频数据,并将有趣的数据添加到数组中并稍后使用,但正如您从Feed中看到的,某些视频链接已"死",这会导致我的代码出现问题.
当我尝试访问$ attrs ['url']时,我得到的错误是"节点不再存在".在我访问它之前,我已经尝试了几个小时找到检查节点是否存在的方法,但我没有运气.
如果有人可以帮助我以相同的结果以其他方式解析feed,或者创建一个if-node-exists检查,我将非常高兴.先感谢您
$url = 'http://gdata.youtube.com/feeds/api/playlists/18A7E36C33EF4B5D?v=2';
$sxml = simplexml_load_file($url);
$i = 0;
$videoobj;
foreach ($sxml->entry as $entry) {
// get nodes in media: namespace for media information
$media = $entry->children('http://search.yahoo.com/mrss/');
// get video player URL
$attrs = $media->group->player->attributes();
$videoobj[$i]['url'] = $attrs['url'];
// get video thumbnail
$attrs = $media->group->thumbnail[0]->attributes();
$videoobj[$i]['thumb'] = $attrs['url'];
$videoobj[$i]['title'] = $media->group->title;
$i++;
}
我想从表中获取数据而不使用正则表达式.我很高兴使用simplexml来解析RSS提要,并想知道它是否可以用来从另一个页面中获取表格.
例如.用curl抓取页面或只是file_get_contents(); 然后使用simplexml来获取内容？
请考虑以下代码:
$string = '<device>
<id>1234</id>
<label>118</label>
<username>root</username>
<password>helloWorld</password>
<hardware>
<memory>4GB RAM</memory>
<storage_drives>
<storage_drive_1>2TB SATA 7,200RPM</storage_drive_1>
<storage_drive_2>1TB SATA 7,200RPM</storage_drive_2>
<storage_drive_3>Not Applicable</storage_drive_3>
<storage_drive_4>Not Applicable</storage_drive_4>
</storage_drives>
</hardware>
</device>';
$xml = new SimpleXMLElement($string);
$deviceDetails = Array();
foreach($xml as $element){
$tag = $element->getName();
$deviceDetails += Array($tag => '$element->$tag)',
);
}
输出$detailsDetails数组如下:
Array
(
[id] => $element->$tag)
[label] => $element->$tag)
[username] => $element->$tag)
[password] => $element->$tag)
[hardware] => $element->$tag)
)
这是错的.
我的问题是,如何$element->$tag开展工作？
我正在尝试使用SimpleXML加载远程URL.
