在PHP中合并XML

这里有点问题，似乎无法合并XML DOMDocumet的“我得到了错误”，致命错误：在第27行调用C:\xampp\htdocs\xmltest\xmltest.php中未定义的方法domeElement:：importNode（）“有人能帮我纠正这段代码吗

<?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();
}
?>

importNode（）
是属于文档的方法，而不是元素。您希望导入到文档（
$dom
）中，然后附加到元素（
$tblclients
）

导入时需要一个节点（并且
$tblclientsXML
不是节点，而是文档），因此导入生成的XML类似于：

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