    <?xml version="1.0" encoding="UTF-8"?>

    

    <my_employee>

    

                            <my_employeename>test</my_employeename>

    

                            <my_employeeaddress>test123</my_employeeaddress>

PHP Code:


<?php


    $doc = new DomDocument;


// Load the xml file into DOMDocument


   $doc->Load('my_employee.xml');


// We retrieve the attribute named id of the my_employee element


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


//Create a new document fragment


   $newDocFragment = $doc ->createDocumentFragment();


//Create an element and append it to the document fragment node


   $newDocFragment->appendChild($doc->createElement("newElement"));


//append the new node(Document Fragment) into the my_employee element


   $my_employee -> appendChild($newDocFragment);


//save the DOMDocument into a file


    $test = $doc->save("saveFile.xml");


    echo "<B>DOMDocument->createDocumentFragment example<B>"


 ?>

Output:


The Content of saveFile.xml is


    <?xml version="1.0" encoding="UTF-8"?>

    

    <my_employee>

    

                   <my_employeename>test</my_employeename>

    

                   <my_employeeaddress>test123</my_employeeaddress>

    

                   <SSN>12343456</SSN>

    

                   <company>TOPXML</company>

    

                   <newElement/>

    

    </my_employee>

The interest of fragment is I think : - only nodes inside the fragment are inserted, not the fragment itself when you insert the fragment - you can append String litteral with the method DOMDocumentFragment->appendXML() So, a fragment may look like this : part of document<li>bla bla </li> ... This fragment is describe with a fragment description that may look like this is you use it as an "XML Fragment Interchange" : <f:fcs xmlns:f="http://www.w3.org/2001/02/xml-fragment" [...] <myOriginalStructure> [...] <f:fragbody/> [...] </myOriginalStructure> cf :: http://www.w3.org/TR/xml-fragment An example could be for "XML Fragment Interchange": $dom = new DomDocument(); $frag = $dom->createDocumentFragment(); $fragbody = $dom->createElementNS( 'http://www.w3.org/2001/02/xml-package', 'p:body' ); $frag->appendXML( 'test fragment<ilo>data</ilo> + an object property + something else ' ); $fragbody->appendChild($frag); $dom->appendChild($fragbody); var_dump($dom->saveXML());

DOMDocumentFragment can be very useful with XPath: you may need to apply an XPath expression to a list of nodes. $dom_doc = new DOMDocument(); $dom_fragment = $dom_doc->createDocumentFragment(); $dom_element_a1 = $dom_fragment->appendChild($dom_doc->createElement('a', 'first node')); $dom_element_a2 = $dom_fragment->appendChild($dom_doc->createElement('a', 'second node')); $xpath = new DOMXpath($dom_doc); $nodes = $xpath->query('a', $dom_fragment); foreach ($nodes as $node) { echo $node->textContent . "\n"; } This way you do not need to embed the nodes within a parent element that could be returned by the xpath expression when you do not want this to happen.
