How does DOMDocument->getElementsByTagName() work in PHP?

The DOMDocument->getElementsByTagName() method in PHP allows you to retrieve a list of elements with a specific tag name from an XML or HTML document loaded into a DOMDocument object. To use this method, you need to create a new instance of DOMDocument, load the XML or HTML content into it, and then call getElementsByTagName() with the desired tag name as the parameter. This method returns a DOMNodeList object containing all elements with the specified tag name. 

// Create a new DOMDocument object
$doc = new DOMDocument();

// Load the XML content from a file
$doc->load('example.xml');

// Get all elements with the tag name 'title'
$titles = $doc->getElementsByTagName('title');

// Loop through the list of title elements
foreach ($titles as $title) {
    echo $title->nodeValue . "<br>";
}
