本文介绍了如何使用Varien_Simplexml_Element类在Magento代码中读取XML节点，并通过示例代码展示如何加载XML文件、读取节点数据以及在XML文件中添加新节点。

I will be using Varien_Simplexml_Element class to read write xml nodes. The path to this class file is lib/Varien/Simplexml/Element.php

Here is a sample XML file which I am going to read through Magento code. I will also be adding an XML node to the following XML data.

Here is the Magento/PHP code to read the XML data. I have kept the XML file in the root directory of Magento installation. The XML file is named test.xml. At first, the XML file is loaded and then it’s node are read with getNode function. Then, I have printed the result.

$xmlPath = Mage::getBaseDir().DS. 'test.xml' ;
$xmlObj = new Varien_Simplexml_Config( $xmlPath );
$xmlData = $xmlObj ->getNode();
echo "<pre>" ; print_r( $xmlData ); echo "</pre>" ;

view plain

$xmlPath = Mage::getBaseDir().DS.'test.xml';
$xmlObj = new Varien_Simplexml_Config($xmlPath);
$xmlData = $xmlObj->getNode();
echo "<pre>"; print_r($xmlData); echo "</pre>";

You can add node with the setNode function. Here, I have set a node inside the node ‘modules’. The name of my new node is ‘mukesh’ and it’s value is ‘chapagain’.
