Just an enhancement of the PHP5 native SimpleXmlElement. Adds the ability to add / replace / remove childs, with or without CDATA, and some method chainings such as dXpath() (for returning the 1st Xpath element found), etc. Fixes the __toString() default method that does not properly convert to your encoding if you're not using UTF-8 (requires PHP 5.4+).

Add the following line into your composer.json :

{
    "require": {
        "bentools/simplexmlextended": "dev-master"
    }
}  

Enjoy.
