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 our The actual link to the 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.
