这里有些错误，似乎无法合并XML DOMDocumet，这是我收到的错误，“致命错误：在第27行的C：\ xampp \ htdocs \ xmltest\ xmltest.php中调用未定义的方法DOMElement :: importNode（）”可以任何人都可以帮助我正确编写此代码…

<?php
// include required files
include 'XML/Query2XML.php';
include 'MDB2.php';

// prepare xml document
$dom = new DomDocument('1.0');

// create tables section
$tables = $dom->appendChild($dom->createElement('tables'));

// create container for tblclients
$tblclients = $tables->appendChild($dom->createElement('tblclients'));

try {
// initialize Query2XML object
$q2x = XML_Query2XML::factory(MDB2::factory('mysql://root:@localhost/db_solconmgr'));

// generate SQL query
$sql = "SELECT ClientID, Client, Contacts, 'Address Line 1' as AddressLine1, 'Address Line 2' as AddressLine2, City, County, 'Zip Code' as ZipCode, Telephone, Fax, Mobile, 'E-mail Address' as EmailAddress, Date FROM tblclients";

// get results as XML
$tblclientsXML = $q2x->getFlatXML($sql);

//$dom = $tblclientsXML;

$node = $tblclients->importNode($tblclientsXML, true);

// send output to browser
header('Content-Type: text/xml');
$dom->formatOutput = true;
echo $dom->saveXML();
} catch (Exception $e) {
echo $e->getMessage();
}
?>
