The Xml class provides an easy way to parse and generate XML fragments and documents. It is an all PHP solution and requires only the Xml/Expat extension to be installed. This library is provided mostly as a convenience to those that do not have access to SimpleXML.

Xml parsing

Parsing Xml with the Xml class requires you to have a string containing the xml you wish to parse.

$input = '<' . '?xml version="1.0" encoding="UTF-8" ?' . '>
        <element id="first-el">
            <name>My element</name>
            <name>Your element</name>
$xml = new Xml($input);

This would create an Xml document object that can then be manipulated and traversed, and reconverted back into a string.

With the sample above you could do the following.

echo $xml->children[0]->children[0]->name;
// outputs 'element'

echo $xml->children[0]->children[0]->children[0]->children[0]->value;
// outputs 'My Element'

echo $xml->children[0]->child('element')->attributes['id'];
//outputs 'first-el'

In addition to the above it often makes it easier to obtain data from XML if you convert the Xml document object to a array.

$xml = new Xml($input);
// This converts the Xml document object to a formatted array
$xmlAsArray = Set::reverse($xml);
// Or you can convert simply by calling toArray();
$xmlAsArray = $xml->toArray();
