我们知道php中的simpleXML没办法直接很方便的添加CDATA格式的数据,这样对我们操作时会有一定的问题,下面我来给各位同学介绍php simpleXML添加CDATA格式数据一种办法,php实例代码如下:
<?php
/**
* to show <title><![CDATA[Site Title]]></title> instead of <title>Site Title</title>
*
*/
class SimpleXMLExtended extends SimpleXMLElement
{
public function addCData($cdata_text)
{
$node = dom_import_simplexml($this);
$no = $node->ownerDocument;
$node->appendChild($no->createCDATASection($cdata_text));
}
}
$xmlFile = 'config.xml';
// instead of $xml = new SimpleXMLElement('<sites/>');
$xml = new SimpleXMLExtended('<sites/>');
$site = $xml->addChild('site');
// instead of $site->addChild('site', 'Site Title');
$site->title = NULL; // VERY IMPORTANT! We need a node where to append
$site->title->addCData('Site Title');
$site->title->addAttribute('lang', 'en');
$xml->asXML($xmlFile);
