// 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";

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

importNode()是属于文档的方法，而不是元素。 您想导入到文档（ $dom ）然后 append 到元素（ $tblclients ）。

导入时需要一个节点（并且$tblclientsXML不是一个节点，它是一个文档），因此导入生成的 XML 看起来类似于：

$tblclientsElement = $tblclientsXML->documentElement;
$tblclientsXML = $dom->importNode($tblclientsElement, TRUE);
$tblclients->appendChild($tblclientsXML);
