Question

我有以下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>

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 />';

        }

我正确地获取元素，除了节点 - 类别和媒体下的项目。类别有多个category_id和category_name项，类似的媒体有多个图像。

使用我目前的代码，我能够只获得中的第一项

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)

我缺少什么？请求帮助......

Answer 1

而不是强制转换为字符串，强制转换为数组：

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

因此，您将获得一系列可以使用的值。

如果您只想显示这些值，请使用implode：

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

php simplexml中节点中的多个子节点 - 仅显示第一个项目
