Are there any specific functions or libraries recommended for XML processing in PHP4?

When working with XML in PHP4, the recommended library for processing XML is the SimpleXML extension. This extension provides a simple and easy-to-use API for accessing and manipulating XML data. By using SimpleXML, you can easily parse XML documents, extract data, and generate XML output. 

// Load XML data from a file
$xml = simplexml_load_file('data.xml');

// Access elements and attributes
echo $xml->element->subelement['attribute'];

// Loop through elements
foreach ($xml->children() as $child) {
    echo $child->getName() . ": " . $child . "<br>";
}

// Create new XML document
$new_xml = new SimpleXMLElement('<root></root>');
$new_xml->addChild('element', 'value');

// Save XML to a file
$new_xml->asXML('new_data.xml');
