What are some best practices for beginners when it comes to utilizing XSL, DOM, and SimpleXML in PHP for HTML rendering and manipulation?

Issue: Beginners often struggle with using XSL, DOM, and SimpleXML in PHP for HTML rendering and manipulation. To help with this, it is important to follow best practices such as understanding the differences between these tools, properly loading and parsing XML data, and effectively using XSL templates for transforming XML into HTML. Code snippet:

// Load XML file using SimpleXML
$xml = simplexml_load_file('data.xml');

// Create a new DOMDocument
$dom = new DOMDocument();
$dom->loadXML($xml->asXML());

// Load XSL file
$xsl = new DOMDocument();
$xsl->load('template.xsl');

// Create XSLT processor and import stylesheet
$xslt = new XSLTProcessor();
$xslt->importStylesheet($xsl);

// Transform XML using XSL
$html = $xslt->transformToXML($dom);

// Output the HTML
echo $html;
