Comment écrire des CDATA en utilisant SimpleXmlElement?
j'ai ce code pour créer et mettre à jour le fichier xml:
<?php
$xmlFile = 'config.xml';
$xml = new SimpleXmlElement('<site/>');
$xml->title = 'Site Title';
$xml->title->addAttribute('lang', 'en');
$xml->saveXML($xmlFile);
?>
génère le fichier xml suivant:
<?xml version="1.0"?>
<site>
<title lang="en">Site Title</title>
</site>
la question Est: y a-t-il un moyen D'ajouter CDATA avec cette méthode/technique pour créer du code xml ci-dessous?
<?xml version="1.0"?>
<site>
<title lang="en"><![CDATA[Site Title]]></title>
</site>

compris! J'ai adapté le code de cette grande solution :
<?php
// http://coffeerings.posterous.com/php-simplexml-and-cdata
class SimpleXMLExtended extends SimpleXMLElement {
public function addCData($cdata_text) {
$node = dom_import_simplexml($this);
$no = $node->ownerDocument;
$node->appendChild($no->createCDATASection($cdata_text));
}
}
$xmlFile = 'config.xml';
// instead of $xml = new SimpleXMLElement('<site/>');
$xml = new SimpleXMLExtended('<site/>');
$xml->title = NULL; // VERY IMPORTANT! We need a node where to append
$xml->title->addCData('Site Title');
$xml->title->addAttribute('lang', 'en');
$xml->saveXML($xmlFile);
?>
fichier XML généré:
<?xml version="1.0"?>
<site>
<title lang="en"><![CDATA[Site Title]]></title>
</site>

voici ma version de cette classe qui a un addChildWithCDATA méthode rapide, basée sur votre réponse :
Class SimpleXMLElementExtended extends SimpleXMLElement {
/**
* Adds a child with $value inside CDATA
* @param unknown $name
* @param unknown $value
*/
public function addChildWithCDATA($name, $value = NULL) {
$new_child = $this->addChild($name);
if ($new_child !== NULL) {
$node = dom_import_simplexml($new_child);
$no = $node->ownerDocument;
$node->appendChild($no->createCDATASection($value));
}
return $new_child;
}
}
utilisez-le simplement comme ça:
$node = new SimpleXMLElementExtended();
$node->addChildWithCDATA('title', 'Text that can contain any unsafe XML charachters like & and <>');

vous pouvez aussi créer une fonction helper pour cela, si vous préférez ne pas étendre SimpleXMLElement:
/**
* Adds a CDATA property to an XML document.
*
* @param string $name
* Name of property that should contain CDATA.
* @param string $value
* Value that should be inserted into a CDATA child.
* @param object $parent
* Element that the CDATA child should be attached too.
*/
$add_cdata = function($name, $value, &$parent) {
$child = $parent->addChild($name);
if ($child !== NULL) {
$child_node = dom_import_simplexml($child);
$child_owner = $child_node->ownerDocument;
$child_node->appendChild($child_owner->createCDATASection($value));
}
return $child;
};

class MySimpleXMLElement extends SimpleXMLElement{
public function addChildWithCData($name , $value) {
$new = parent::addChild($name);
$base = dom_import_simplexml($new);
$docOwner = $base->ownerDocument;
$base->appendChild($docOwner->createCDATASection($value));
}
}
$simpleXmlElemntObj = new MySimpleXMLElement('<site/>');
/* USAGE */
/* Standard */
$simpleXmlElemntObj->addChild('Postcode','1111');
/* With CDATA */
$simpleXmlElemntObj->addChildWithCData('State','Processing');
/* RESULT */
/*
<?xml version="1.0"?>
<site>
<Postcode>1111</Postcode>
<State><![CDATA[Processing]]></State>
</site>
*/

voici ma solution combinée avec l'ajout de child avec CDATA ou L'ajout de CDATA au noeud.
class SimpleXMLElementExtended extends SimpleXMLElement
{
/**
* Add value as CData to a given XML node
*
* @param SimpleXMLElement $node SimpleXMLElement object representing the child XML node
* @param string $value A text to add as CData
* @return void
*/
private function addCDataToNode(SimpleXMLElement $node, $value = '')
{
if ($domElement = dom_import_simplexml($node))
{
$domOwner = $domElement->ownerDocument;
$domElement->appendChild($domOwner->createCDATASection("{$value}"));
}
}
/**
* Add child node with value as CData
*
* @param string $name The child XML node name to add
* @param string $value A text to add as CData
* @return SimpleXMLElement
*/
public function addChildWithCData($name = '', $value = '')
{
$newChild = parent::addChild($name);
if ($value) $this->addCDataToNode($newChild, "{$value}");
return $newChild;
}
/**
* Add value as CData to the current XML node
*
* @param string $value A text to add as CData
* @return void
*/
public function addCData($value = '')
{
$this->addCDataToNode($this, "{$value}");
}
}
// Usage example:
$xml_doc = '<?xml version="1.0" encoding="utf-8"?>
<offers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1">
</offers>';
$xml = new SimpleXMLElementExtended($xml_doc);
$offer = $xml->addChild('o');
$offer->addAttribute('id', $product->product_id);
$offer->addAttribute('url', 'some url');
$cat = $offer->addChildWithCData('cat', 'Category description as CDATA');
// or
$cat = $offer->addChild('cat');
$cat->addCData('Category description as CDATA');
