    In most cases if you expect XML (or XHTML) as output you better use transformToXML() directly. You gain better control over xsl:output attributes, notably omit-xml-declaration.

    Instead of :
    $proc = new XSLTProcessor();
    $proc->importStylesheet($xsl);
    $dom = $proc->transformToDoc($xml);
    echo $dom->saveXML();

    do use :
    $proc = new XSLTProcessor();
    $proc->importStylesheet($xsl);
    $newXml = $proc->transformToXML($xml);
    echo $newXml;

    In the first case, <?xml version="1.0" encoding="utf-8"?> is added whatever you set the omit-xml-declaration while transformToXML() take the attribute into account.
