PHP Simple XML Parser



Hello folks! welcome to another section of our tutorial on PHP. In this section of our PHP tutorial, we will be discussing about the PHP Simple XML Parser. 

The simple xml parser is used to parse Names, attributes, and textual contents.

Simple XML Functions

Simple xml functions are shown below -

simplexml_load_file()

This function accepts file path as a first parameter and its very compulsory.

simplexml_load_file(($fileName,$class,$options,$ns,$is_prefix)

simplexml_load_string()

This function accepts the string instead of file reference.

simplexml_load_string($XMLData,$class,$options,$ns,$is_prefix)


simplexml_import_dom()

This xml function accepts Dom formatted xml content and then converts into simple xml.

simplexml_load_string($DOMNode,$class)

Example

The below example shows how to parse an XML data file -

<?php
   $data = "<?xml version = '1.0' encoding = 'UTF-8'?>
   
   <note>
      <Course>Web Development</Course>
      <Subject>HTML</Subject>
      <Company>Web Design Tutorialz</Company>
      <Price>$20</Price>
   </note>";
   
   $xml = simplexml_load_string($data) or die("Error: Cannot create object");
?>
<html>

   <head>
      <body>
         
         <?php
            print_r($xml);
         ?>
      
      </body>
   </head>
   
</html>

Output

When the above code is executed, it will produce the following result -

SimpleXMLElement Object ( [Course] => Web Development [Subject] => HTML [Company] => Web Design Tutorialz [Price] => $20 )

We can also call an xml data file as shown below and it produces the same result as shown above -

<?php
   $xml = simplexml_load_file("data") or die("Error: Cannot create object");
   print_r($xml);
?>
