PHP and XML: Using the Expat function (iii)

PHP and XML: Using the Expat function (iii)

How do I use this class in a PHP script? is actually very simple. Here's an example:


First the class definition needs to be included in the script

Require (Class_dir. " Class. Newsboy.php ");

We then create an instance of the class and set the actual link to the file for our XML document.

$news = new Newsboy ();
$news->xml_file = "Xml/mynews.xml";

Or

$news->xml_file = "Http://xmldocs.mysite.com/mynews.xml"

Then we call the parser to parse the document.

$news->parse ();

Then we print the HTML to the screen.

Print ($news->html);

Also, the class must be freed at the end of completion.

$news->destroy ();

That's all you have to do.
