What are common causes of XML processing errors in PHP applications?

Common causes of XML processing errors in PHP applications include invalid XML syntax, improperly formatted XML documents, and issues with encoding. To solve these errors, it is important to validate the XML data before processing it, handle encoding properly, and use PHP's built-in XML functions carefully to avoid errors. 

// Example of validating XML data before processing
$xml = '<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don\'t forget me this weekend!</body></note>';

$doc = new DOMDocument();
$doc->loadXML($xml);

if ($doc->validate()) {
    // Process the XML data
} else {
    echo "Invalid XML data";
}
