L’assistant XML simplifie les créations de documents XML.


serialize($data, $options = array())

  • mixed $data - The content to be converted to XML

  • mixed $options - The data formatting options. For a list of valid options, see Xml::__construct()

    • string $options[“root”] - The name of the root element, defaults to “#document”

    • string $options[“version”] - The XML version, defaults to “1.0”

    • string $options[“encoding”] - Document encoding, defaults to “UTF-8”

    • array $options[“namespaces”] - An array of namespaces (as strings) used in this document

    • string $options[“format”] - Specifies the format this document converts to when parsed or rendered out as text, either “attributes” or “tags”, defaults to “attributes”

    • array $options[“tags”] - An array specifying any tag-specific formatting options, indexed by tag name. See XmlNode::normalize()

    • boolean $options[“slug”] - A boolean to indicate whether or not you want the string version of the XML document to have its tags run through Inflector::slug() (Which makes “TAGNAME” became “t_a_g_n_a_m_e”). Defaults to true.

The serialize method takes an array and creates an XML string of the data. This is commonly used for serializing model data.

echo $this->Xml->serialize($data);
 // format will be similar to:
 // <model_name id="1" field_name="content" />

The serialize method acts as a shortcut to instantiating the XML built-in class and using the toString method of that. If you need more control over serialization, you may wish to invoke the XML class directly.

You can modify how a data is serialized by using the format attribute. By default the data will be serialized as attributes. If you set the format as « tags » the data will be serialized as tags.

    [Baker] => Array
            [0] => Array
                    [name] => The Baker
                    [weight] => heavy
            [1] => Array
                    [name] => The Cook
                    [weight] => light-weight
     <baker name="The Baker" weight="heavy" />
     <baker name="The Cook" weight="light-weight" />
pr($this->Xml->serialize($data, array('format' => 'tags')));
        <name><![CDATA[The Baker]]></name>
        <name><![CDATA[The Cook]]></name>


The elem method allows you to build an XML node string with attributes and internal content, as well.

string elem (string $name, $attrib = array(), mixed $content = null, $endTag = true)

echo $this->Xml->elem('count', array('namespace' => 'myNameSpace'), 'content');
// generates: <myNameSpace:count>content</count>

If you want to wrap your text node with CDATA, the third argument should be an array containing two keys: “cdata” and “value”

echo $this->Xml->elem('count', null, array('cdata'=>true,'value'=>'content'));
// generates: <count><![CDATA[content]]></count>
