Are there any best practices or optimizations to consider when working with DOM manipulation in PHP to improve performance and avoid unnecessary operations like repeated calls to saveXML()?

Repeated calls to saveXML() can be avoided by storing the result in a variable and reusing it when needed. This can improve performance by reducing unnecessary operations on the DOM. Additionally, it is a good practice to minimize DOM manipulation operations to only what is necessary to achieve the desired result. 

// Load XML content into a DOMDocument object
$xml = new DOMDocument();
$xml->loadXML($xmlContent);

// Perform necessary DOM manipulation operations
// For example, adding a new element
$newElement = $xml->createElement('newElement');
$xml->documentElement->appendChild($newElement);

// Save the updated XML content in a variable for reuse
$updatedXmlContent = $xml->saveXML();
