PHP and simpleXML

When you want to process an XML file in PHP, there are two possibilities: either we use SimpleXML or we go through DOMDocument. In this article I will deal more specifically with SimpleXML.

To load a file, just use the simplexml_load_file method

$xml - simplexml_load_file ($file);

By doing so, you get a SimpleXMLElement.

If the XML has a namespace, it is imperative to add it to the element, otherwise you won’t be able to browse it.

 $xml-registerXPathNamespace ('n', 'http://www.w3.org/TR/html4/');

Then it is possible to retrieve the desired data

echo $movies--movie[0]--plot;

we can also, if desired, use xpath. It is very important that each node has the namespace, in our example “n”

echo $xml-xpath ('/n:movie/n:plot')
