DOMDocument Function importNode

PHP Version: (No version information, might be only in CVS. I have used this function in PHP5)

DOM: W3C DOM Level 1

Description

This function creates a new Element. This method generally used to copy an element from one DOMDocument to another DOMDocument.

Usage:

objectDOMDocument->importNode ( object importedNode [, bool deep])

This function returns a copy of the node to import and associates it with the current document. DOMException is thrown if node cannot be imported.

Parameters:

importedNode – The Node you want to import to your document.

deep – This is used to tell whether you want to import node with all children or only the node it self.

Example:

The XML file, which I have used contains following data. I have stored this file in “c:/topxml_demo/php/xml_files/employee.xml” directory.

     <?xml version="1.0"?>

<employee>

     <employeename id="myId">test</employeename>

     <employeeaddress>test123</employeeaddress>

     <SSN>12343456</SSN>

     <company>TOPXML</company>

</employee>

PHP Code:

<?php

    $doc = new DomDocument;

// Load the xml file into DOMDocument

$doc->Load('C:/topxml_demo/php/xml_files/employee.xml');

//create a new DOM Document

$newDoc = new DomDocument;

// We retrieve the employee element from  docDomDocument

$employee = $doc->getElementsByTagName('employee')->item(0);

//import with all node with childrens. If you want only node then pass false.

$importedElement = $newDoc->importNode($employee,true);

//add the new imported element to the $newDocDomDocument

$newDoc->appendChild($importedElement);

//save the new DOMDocument into a file

$test = $newDoc->save("C:/topxml_demo/php/xml_files/save1.xml");

 echo "<BR><B>DOMDocument->importNode example with all childs<B>"

 ?>

Output:

This is imported with all childrens.The Content of save1.xml is

<?xml version="1.0"?>

<employee>

     <employeename id="myId">test</employeename>

     <employeeaddress>test123</employeeaddress>

     <SSN>12343456</SSN>

     <company>TOPXML</company>

     </employee>

If you want only the node then the PHP code would be

$importedElement = $newDoc->importNode($employee,false);

 and XML document would be

<?xml version="1.0"?>

<employee/>
