    Örnek 1 - Bir SimpleXMLElement nesnesine öznitelikleriyle çocuk elemanlar eklemek

    <?php

    include 'example.php';

    $sxe = new SimpleXMLElement($xmlstr);
    $sxe->addAttribute('type', 'documentary');

    $movie = $sxe->addChild('movie');
    $movie->addChild('title', 'PHP2: More Parser Stories');
    $movie->addChild('plot', 'This is all about the people who make it work.');

    $characters = $movie->addChild('characters');
    $character = $characters->addChild('character');
    $character->addChild('name', 'Mr. Parser');
    $character->addChild('actor', 'John Doe');

    $rating = $movie->addChild('rating', '5');
    $rating->addAttribute('type', 'stars');

    echo     $sxe->asXML();

    ?>

    Yukarıdaki örnek şuna benzer bir çıktı üretir:

    <?xml version="1.0" standalone="yes"?>
<movies type="documentary">
 <movie>
  <title>PHP: Behind the Parser</title>
  <characters>
   <character>
    <name>Ms. Coder</name>
    <actor>Onlivia Actora</actor>
   </character>
   <character>
    <name>Mr. Coder</name>
    <actor>El Act&#xD3;r</actor>
   </character>
  </characters>
  <plot>
   So, this language. It's like, a programming language. Or is it a
   scripting language? All is revealed in this thrilling horror spoof
   of a documentary.
  </plot>
  <great-lines>
   <line>PHP solves all my web problems</line>
  </great-lines>
  <rating type="thumbs">7</rating>
  <rating type="stars">5</rating>
 </movie>
 <movie>
  <title>PHP2: More Parser Stories</title>
  <plot>This is all about the people who make it work.</plot>
  <characters>
   <character>
    <name>Mr. Parser</name>
    <actor>John Doe</actor>
   </character>
  </characters>
  <rating type="stars">5</rating>
 </movie>
</movies>

    To complete Volker Grabsch's comment, stating :
    "Note that although addChild() escapes "<" and ">", it does not escape the ampersand "&"."

    To work around that problem, you can use direct property assignment such as :

    <?php
    $xmlelement    ->value = 'my value < > &';
    // results in <value>my value &lt; &gt; &amp;</value>
    ?>

    instead of doing :

    <?php
    $xmlelement    ->addChild('value', 'my value < > &');
    // results in <value>my value &lt; &gt; &</value> (invalid XML)
    ?>

    Here is a class with more functions for SimpleXMLElement :

    <?php
    /**
    *
    * Extension for SimpleXMLElement
    * @author Alexandre FERAUD
    *
    */
    class ExSimpleXMLElement extends SimpleXMLElement
    {
    /**
    * Add CDATA text in a node
    * @param string $cdata_text The CDATA value to add
    */
    private function addCData($cdata_text)
    {
    $node= dom_import_simplexml($this);
    $no = $node->ownerDocument;
    $node->appendChild($no->createCDATASection($cdata_text));
    }

    /**
    * Create a child with CDATA value
    * @param string $name The name of the child element to add.
    * @param string $cdata_text The CDATA value of the child element.
    */
    public function addChildCData($name,$cdata_text)
    {
    $child = $this->addChild($name);
    $child->addCData($cdata_text);
    }

    /**
    * Add SimpleXMLElement code into a SimpleXMLElement
    * @param SimpleXMLElement $append
    */
    public function appendXML($append)
    {
    if (    $append) {
    if (    strlen(trim((string) $append))==0) {
    $xml = $this->addChild($append->getName());
    foreach(    $append->children() as $child) {
    $xml->appendXML($child);
    }
    } else {
    $xml = $this->addChild($append->getName(), (string) $append);
    }
    foreach(    $append->attributes() as $n => $v) {
    $xml->addAttribute($n, $v);
    }
    }
    }
    }
    ?>

    In the docs for google sitemaps it is required an element for mobile sitemaps that looks like this: <mobile:mobile/>

    I used some time to figure out how to make it, but it is quite simple when understood.

    $mobile_schema = 'http://www.google.com/schemas/sitemap-mobile/1.0';

    //Create root element
    $xml_mobile = new SimpleXMLElement('
    <?xml version="1.0" encoding="UTF-8"?>
    <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:mobile="'.$mobile_schema.'"></urlset>
    ');

    //Add required children
    $url_mobile = $xml_b_list_mobile->addChild('url');
    $url_mobile->addChild('loc', 'your-mobile-site-url');
    $url_mobile->addChild('mobile:mobile', null, $mobile_schema);

    For this to work properly the attribute xmlns:mobile must be set in the root node, and then used as namespace(third argument) when creating the mobile:mobile child with null as value.

    Want to continue the ampersand (&) chain problem.

    Sometimes, you would want to assign (=) addChild.
    This trick will helps you to do this.

    <?php
    $webOrders     = new SimpleXMLElement('<?xml version="1.0"?><WebOrders></WebOrders>');
    $webOrder = $webOrders->addChild('WebOrder');
    $product = $webOrder->addChild('Product');
    $product[0] = 'T&M';
    $product->addAttribute('price', 19.99);
    $product->addAttribute('qty', 2);
    var_dump($webOrders->asXML());
    ?>

    OUTPUT would be:

    <?xml version="1.0" encoding="UTF-8"?>
    <WebOrders>
    <WebOrder>
    <Product price="19.99" qty="2">T&amp;M</Product>
    </WebOrder>
    </WebOrders>

    Note that although addChild() escapes "<" and ">", it does not escape the ampersand "&".

    So addChild() is unsuited to handle user-defined input!

    Instead, you will have to replace all "&" with "&amp;" before calling addChild().

    Or, use htmlspecialchars() which also replaces other characters, but won't do any harm as addChild() won't replace those again.

    The class below allows you to write CDATA and to add additional attributes.

    <?php
    class SimpleXMLElementExtended extends \SimpleXMLElement
    {
    public function     addChildWithCData($name, $value)
    {
    $child = parent::addChild($name);
    $element = dom_import_simplexml($child);
    $docOwner = $element->ownerDocument;
    $element->appendChild($docOwner->createCDATASection($value));
    return     $child;
    }
    }
    ?>

    Example:
    <?php
    $xml     = new SimpleXMLElementExtended('<xml></xml>');
    $content = $xml->addChildWithCData('content', 'Title of the page');
    $content->addAttribute('id', 1);
    $content->addAttribute('enabled', 'true');

    // Output:
    // <xml>
    // <content id="1" enabled="true"><![CDATA[Title of the page]]></content>
    // </xml>
    ?>
