PHP- Simple XML

    This simple XML parser will parse the name, containing attributes and the text content within the simple XML file. These are tree-based parsers. PHP supports some of the XML functions that are described below.

    • simplexml_load_file()- this function has five parameters among which the first parameter is mandatory as it takes the file path to load the XML file. 
    simplexml_load_file(($fileName,$class,$options,$ns,$is_prefix)
    • simplexml_load_string()- this function also takes five parameters among which the first parameter is mandatory to pass which is the string rather than the file reference. 
    simplexml_load_string($XMLData,$class,$options,$ns,$is_prefix)
    • simplexml_import_dom()- this function will accept the XML content in complex DOM format and allows it to convert the complex XML into simple XML format. This function will take two parameters. 
    simplexml_load_string($DOMNode,$class)

    Example: 

    <?php
   $data = "<?xml version = '1.0' encoding = 'UTF-8'?>
   <data>
      <Subject>Program</Subject>
      <Content>CS</Content>
      <Price>10</Price>
   </data>";
   $db_xml = simplexml_load_string($data) or die("Error");
?>
<html>
   <head>
      <body>
         <?php
            print_r($db_xml);
         ?>
     </body>
   </head>
</html>

    Output: 

    SimpleXMLElement Object ( [Subject] => Program [Content] => CS [Price] => 10 )
