Check for Valid XML with PHP
Simple function to check if XML is valid. It just loads the XML into DOMDocument and checks for errors.
[source language=“php“]
/**
* Takes XML string and returns a boolean result where valid XML returns true
*/
function is_valid_xml ( $xml ) {
libxml_use_internal_errors( true );
$doc = new DOMDocument(‚1.0‘, ‚utf-8‘);
$doc->loadXML( $xml );
$errors = libxml_get_errors();
return empty( $errors );
}

}

echo $string;
