PHP - Simple XML

       No comments

The simple XML parser

The simple XML parser is used to parse Name, attributes and textual content.

The simple XML functions are shown below −

simplexml_load_file()

This function accepts file path as a first parameter and it is mandatory.

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 function accepts DOM formatted XML content and it converts into simple XML.

simplexml_load_string($DOMNode,$class)

The following example shows, How to parse a xml data file.

<?php
   $data = "<?xml version = '1.0' encoding = 'UTF-8'?>
   
   <note>
      <Course>Android</Course>
      <Subject>Android</Subject>
      <Company>TutorialsPoint</Company>
      <Price>$10</Price>
   </note>";
   
   $xml = simplexml_load_string($data) or die("Error: Cannot create object");
?>
<html>

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

It will produce the following result −

SimpleXMLElement Object ( [Course] => Android [Subject] => Android [Company] => TutorialsPoint [Price] => $10 )

We can also call a 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);
?>
