The DOMElement::getAttributeNS() function is an inbuilt function in PHP which is used to get the value of the attribute in a specific namespace with local name for the current node.
Syntax:
string DOMElement::getAttributeNS( string $namespaceURI, string $localName )
Parameters: This function accepts two parameters as mentioned above and described below:
- $namespaceURI: It specifies the namespace URI.
- $localName: It specifies the local name.
Return Value: This function returns a string value containing the value of attribute, or an empty string if no attribute with the given localName and namespaceURI is found.
Below examples illustrate the DOMElement::getAttributeNS() function in PHP:
Example 1:
<?php // Create a new DOMDocument $dom = new DOMDocument();
// Load the XML $dom ->loadXML("<?xml version=\"1.0\"?>
<body xmlns:x=\"my_namespace\"> <x:div x:attr=\"value\" > DIV 1 </x:div>
</body>"); // Get the elements by tagname $elements = $dom ->getElementsByTagName( 'div' );
// Get the attribute node value $nodeValue = $elements [0]->getAttributeNS( 'my_namespace' , 'attr' );
echo $nodeValue ;
?> |
Output:
value
Example 2:
<?php // Create a new DOMDocument $dom = new DOMDocument();
// Load the XML $dom ->loadXML("<?xml version=\"1.0\"?>
<root> <body xmlns:x=\"my_namespace1\"> <x:div x:id=\"my_id1\" > DIV 1 </x:div>
<x:div x:id=\"my_id2\" > DIV 1 </x:div>
</body> <body xmlns:xi=\"my_namespace2\"> <xi:div xi:id=\" new \" > DIV 1 </xi:div>
</body> </root>"); // Get the elements by tagname $elements = $dom ->getElementsByTagName( 'div' );
foreach ( $elements as $element ) {
// Get node value only from my_namespace1
$nodeValue = $element ->getAttributeNS( 'my_namespace1' , 'id' );
if ( $nodeValue ) {
echo $nodeValue . '<br>' ;
}
} ?> |
Output:
my_id1 my_id2
