How does using DOMDocument in PHP compare to other methods for handling XML-based files like SVG?

When handling XML-based files like SVG in PHP, using the DOMDocument class provides a powerful and convenient way to parse, manipulate, and generate XML documents. DOMDocument allows for easy traversal of the XML structure, making it ideal for tasks such as extracting data, modifying elements, or creating new XML files. Compared to other methods like simplexml_load_file or manual string manipulation, DOMDocument offers more flexibility and control over the XML data. 

// Load an SVG file using DOMDocument
$svgFile = 'example.svg';
$doc = new DOMDocument();
$doc->load($svgFile);

// Example: Get the width and height attributes of the SVG element
$svgElement = $doc->documentElement;
$width = $svgElement->getAttribute('width');
$height = $svgElement->getAttribute('height');

echo "SVG width: $width, height: $height";
