PHP and XML: Using expat function (3)

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


First the class definition needs to be included in the script

require (CLASS_DIR."class.Newsboy.php");

Then, We create an instance of the class and set the fileness to the actual link to 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 analyzer to analyze the document.

$news->parse();

Then we print the html to the screen.

print ($news->html);

And, at the end, the class must be released when completed.

$news->destroy();

That’s all there is to do.
