In the effiliation pluggin for prestashop, i've found this code:
$values->addChild('marque', '<![CDATA['.$product['manufacturer_name'].']]>');
when in $product['manufacturer_name'], i have Cyril & Nathalie Daniel, the output is <![CDATA[Cyril,
as opposed to the normal case: <![CDATA[Foo Bar]]>
Can the 2nd argument of SimpleXMLElement::addChild can contain & ? Do i have to use some htmlentities on the manufacturer name ?
