Answer 1

public  function printResult($raw_data){
    // adding Content Type
    header("Content-type: text/xml");
    // Converts PHP Array to XML with the root element being 'root-element-here'
    $xml = Excellence_Envision_Helper_Errorflile::createXML('LoggedError', $raw_data);

    return $xml->saveXML();

    }

Try to remove this code from your function and I think it will work fine then.

header("Content-type: text/xml");

Answer 2

If the xml has special characters as values and ';' is not included it throws the error. For Example, if '<' is replaced with < and ';' after '&lt' is forgotten, browser (at least Chrome) displays the same error.
