多个孩子在PHP中的SimpleXML，只显示第一个项目节点

Question

我有下面的XML文件，我使用PHP SimpleXML来解析数据：

<?xml version="1.0"?> 
<root> 
<update_time>2014-06-09</update_time> 
<item> 
<url>http://www.myproducts.com</url> 
<name>Wireless Bluetooth Speaker - White</name> 

<category> 
<parent_id>53</parent_id> 
<parent_name>Electronics</parent_name> 

<category_id>150</category_id> 
<category_name>Mini Speaker</category_name> 

<parent_id>81</parent_id> 
<parent_name>Bluetooth Function Devices</parent_name> 

<category_id>1384</category_id> 
<category_name>Bluetooth Function Speaker</category_name> 
</category>

</media>

<![CDATA[<p><span style="font-size: small;"><span style="font-family: Arial;">This mini speaker is in unique cup appearance model design. </span></span></p>]]> 
</short_description> 

<description> 
<![CDATA[<p><strong><span style="font-size: small;"><span style="font-family: Arial;">Features:</span></span></strong> 
* Special tablet PC<br /> 
* Protect your tablet screen from dust and hand print<br /> 
* Size: 17.3 x 10.5cm</span></span></p> 
<p><span style="font-size: small;"><span style="font-family: Arial;">Package included:<br /> 
1* Screen protective film <br /> 
</span></span></p>]]> 
</description> 

</item> 
</root> 

我的PHP代码如下：

<?php 
     if(file_exists('feed.xml')) 
     { 
     $xml = simplexml_load_file('feed.xml', 'SimpleXMLElement', LIBXML_NOCDATA); 
     } 
     foreach($xml->item as $products) 
     { 

     echo 'URL:' . (string)$products->url .'<br />'; 
     echo 'Name:' . (string)$products->name .'<br />';   
     echo 'Category_ID:' . (string)$products->category->category_id .'<br />';//for subcategory 
     echo 'Category_Name:' . (string)$products->category->category_name .'<br />'; 
     echo 'Images:' . (string)$products->media->images .'<br />'; 
     echo 'Short Description:' . strip_tags((string)$products->short_description) .'<br />'.'<br />'; 
     echo 'Description:' . strip_tags((string)$products->description) .'<br />'; 
     echo '<br />'; 

     } 

我正在获取元素，除了节点类别和媒体下的项目。类别具有多个category_id和category_name项目，类似地，媒体具有多个图像。

有了我现在的代码我能够获得两种

category->category_id, (category_id =150) 

category->category_name (Category_Name:Mini Speaker) 

media->images (http://www.myshop.com/media/catalog/product/f/i/file_2111_316.jpg) 

我失去了什么只有第一项 ???请求帮助......

代替铸造的字符串，转换为数组：

$category_id = (array) $products->category->category_id; 
$category_name = (array) $products->category->category_name; 

所以你会得到价值一起工作的数组。

如果你只想显示这些值使用破灭：

echo 'Category_ID:' . implode(' ', (array) $products->category->category_id) . '<br />';
