SimpleXML

SimpleXML is a PHP extension that allows users to easily^[1][2] manipulate/use XML data. It was introduced in PHP 5 as an object oriented approach to the XML DOM providing an object that can be processed with normal property selectors and array iterators.^[3][4] It represents an easy way of getting an element's attributes and textual content if you know the XML document's structure or layout.^[5]

Compared to DOM or the Expat parser, SimpleXML takes a fewer lines of code to read text data from an element.^[6][7]
