simple exemple of node cloning



<?xml version="1.0"?>



<book type="paperback">

    <title name='MAP'>Red Nails</title>

    <price>$12.99</price>

    <author>

        <name first="Robert" middle="E" last="Howard"/>

        <birthdate>9/21/1977</birthdate>

    </author>

    <author>

        <name first="Arthur" middle="Mc" last="Kayn"/>

    </author>

</book>



<?php



//filename xml file to use

$file = 'book.xml';



$doc = new domDocument;



if (file_exists($file)) {

    $doc->load($file);

} else {

    exit('Erreur !.');

}



$xpath = new domXPath($doc);



$query = "//author/*";

$xpathQuery = $xpath->query($query);



$size = $xpathQuery->length;

for ($i=0; $i<$size; $i++){

    $node = $xpathQuery->item($i);

    if ($node->nodeName == 'birthdate' && $node->hasChildNodes() && $node->firstChild->textContent != ''){

        $clonenode = $node->cloneNode(true);

        $refnode = $node;

    }

}

for ($i=0; $i<$size; $i++){

    $node = $xpathQuery->item($i);

    if (!$node->isSameNode($refnode)){

        $newnode = $node->appendChild($clonenode);

    }

}



print $doc->saveXML();

For those converting from PHP 4 DOM XML to PHP 5 DOM extension:



In the old days, DOM XML's clone_node() was the way to copy nodes from one DOM to another, as well as to perform intra-DOM copies.  Nowadays, DOM's cloneNode() is the intra-DOM solution, but see importNode() (http://php.net/dom-domdocument-importnode) to copy nodes from one DOM to another.



So to append root node of $dom2 and all its children into root node of $dom1:



PHP 4 (DOM XML):



<?

$root1 = $dom1->document_element();

$other_node = $dom2->document_element();

$root1->append_child($other_node->clone_node(true));

?>



PHP 5 (DOM):



<?

$dom1->documentElement->appendChild(

  $dom1->importNode($dom2->documentElement, true));

?>
