DOMNode Function isSupported

PHP Version: (No version information might be only in CVS. I have used this function in PHP5)

Description

This function checks if a feature supported by a version or not.

Usage:

boolDOMNode->isSupported ( string feature, string version)

Checks if feature is supported for specified version.

PHP Code:

<?php

//put all features in the array so that we can test whether DOMNode implements a

//particular feature or not

$feature = array ( 'Core module' => 'Core',

               'XML module' => 'XML',

               'HTML module' => 'HTML',

               'Views module' => 'Views',

               'Style Sheets module' => 'Stylesheets',

               'CSS module' => 'CSS',

               'CSS2 module' => 'CSS2',

     'Events module' => 'Events',

               'User interface Events module' => 'UIEvents',

               'Mouse Events module' => 'MouseEvents',

               'Mutation Events module' => 'MutationEvents',

               'HTML Events module' => 'HTMLEvents',

               'Range module' => 'Range',

               'Traversal module' => 'Traversal',

               );

//create a dom node.

$node = new DOMNode;

echo "<HTML>";

echo "<Head>";

echo "<title>Example of DOMNode->isSupported</title>";

echo "<Head>";

echo "<body>";

echo "<PRE>";

foreach ( $feature as $f => $k ) {

      if ( $node->isSupported( $k, '2.0' ) ) {

           echo "DOMNode supports feature {$f}<br>\n";

      } else {

           echo "DOMNode does not support feature {$f}<br>\n";

      }

echo "</PRE>";

echo "</body>";

echo "</HTML>";

?>

Output:

The expected output would be:

DOMNode does not support feature Core module

DOMNode supports feature XML module

DOMNode does not support feature HTML module

DOMNode does not support feature Views module

DOMNode does not support feature Style Sheets module

DOMNode does not support feature CSS module

DOMNode does not support feature CSS2 module

DOMNode does not support feature Events module

DOMNode does not support feature User interface Events module

DOMNode does not support feature Mouse Events module

DOMNode does not support feature Mutation Events module

DOMNode does not support feature HTML Events module

DOMNode does not support feature Range module

DOMNode does not support feature Traversal module
 
If you change the version to 1.0m the output would be:
 
DOMNode supports feature Core module //this is not supported in version 2.0

DOMNode supports feature XML module

DOMNode does not support feature HTML module

DOMNode does not support feature Views module

DOMNode does not support feature Style Sheets module

DOMNode does not support feature CSS module

DOMNode does not support feature CSS2 module

DOMNode does not support feature Events module

DOMNode does not support feature User interface Events module

DOMNode does not support feature Mouse Events module

DOMNode does not support feature Mutation Events module

DOMNode does not support feature HTML Events module

DOMNode does not support feature Range module

DOMNode does not support feature Traversal module
