Reading XML file - PHP

 

The easiest and simplest way to read XML file is using SimpleXML.

 

We'll consider a simple XML file test.xml with the following nodes and values.

---

<!-- Test.xml --> 

<root>

   <node1>Hello</node1>

   <node2>World</node2>

    <node3>This is simple Example of Parsing XML files </node3>

<root>  

 

---

 Loading a XML file

$xml=simplexml_load_file("filename");

Parsing a Node value 

$node=$xml->node_name;

  

 Example to demonstrate the usage of simpleXML

---

<?php
$xml=simplexml_load_file("test.xml");
echo $xml ->node3;
 echo '<br/>';
foreach($xml->children() as $child)   // children() get all the child nodes in the XML file.
{
      echo 'Node_name: '.$child ->getName().'   ';      // displays the node_name.
     echo 'Node_value: '.$child.'<br/>';   // displays the node value.
}
?>  

---

Output will be displayed as follows

---

This is a simple example of parsing XML files
Node_name: node1 Node_value: Hello
Node_name: node2 Node_value: World
Node_name: node3 Node_value: This is a simple example of parsing XML files 

---

Nodes having nested nodes can be parsed using the above method by using foreach loop.
