How can whitespace affect the processing of XML elements in PHP?

Whitespace can affect the processing of XML elements in PHP by causing issues with parsing and manipulating the XML data. To solve this problem, you can use the `LIBXML_COMPACT` option when loading the XML data in PHP. This option removes unnecessary whitespace and makes the parsing more efficient. 

// Load the XML data with the LIBXML_COMPACT option to remove whitespace
$xml = new DOMDocument();
$xml->loadXML($xmlString, LIBXML_COMPACT);
