Answer 1

I guess that you are trying to get each report node as well as its contents. You may do the following:

<?php
    $doc = DOMDocument::loadXML(' x m l  s t r i n g ');

    $reportNodeList = $doc->getElementsByTagName('report');
    foreach($reportNodeList as $reportNode) {
        echo htmlspecialchars($doc->saveXML($reportNode));
    }
?>

Answer 2

If you use simpleXMl or simpleXMIterator to parse, each node would be a simpleXML element that you could independently output as XML.
