在PHP解析XML
问题描述:
我解析一个XML,但有一个标签,其中包含图像和文字两个,我想在表格的不同列中分离图像和文本在我的设计布局,但我不知道该怎么做。请帮帮我。我的PHP文件是:在PHP解析XML
<?php
$RSS_Content = array();

要你需要分析存储在里面的描述再次元素作为XML的HTML的图像和描述分开。幸运的是,它在该元素内部是有效的XML,因此您可以直接使用SimpleXML,以下代码示例采用URL并将每个项目 * description *转换为仅文本并提取src属性图像以将其存储为图像元件:
<item>
<title>Fake encounter: BJP backs Kataria, says CBI targeting Modi</title>
<link>http://ibnlive.in.com/news/fake-encounter-bjp-backs-kataria-says-cbi-targeting-modi/391802-37-64.html</link>
<description>The BJP lashed out at the CBI and questioned its 'shoddy investigation' into the Sohrabuddin fake encounter case.</description>

<image>http://static.ibnlive.in.com/ibnlive/pix/sitepix/05_2013/bjplive_kataria3.jpg</image>
</item>
的代码的例子是:
$url = 'http://ibnlive.in.com/ibnrss/top.xml';
$feed = simplexml_load_file($url);
$items = $feed->xpath('(//channel/item)');
foreach ($items as $item) {
list($description, $image) =
simplexml_load_string("<r>$item->description</r>")
->xpath('(/r|/r//@src)');
$item->description = (string)$description;
$item->image = (string)$image;
}
然后可以导入的SimpleXML成一个DOMElement与然而dom_import_simplexml()
说实话,我只是想包那个小HTML创建以及进入的SimpleXML的一个foreach,因为你可以利用LimitIterator
的寻呼以及你可能与DOM文档和您访问的数据实际上很容易与SimpleXML一起传递,只需简单地将XML元素传递为SimpleXMLElements,而不是首先解析为数组,然后再处理数组。这是没有意义的。
你已经尝试过什么,它在哪里破裂?并向我们展示您的XML。 –
