AJAX-based is one of the primary target of my site at the very beginning. What i was thinking about was putting all the content in one page, and all the data were loaded at background.

But there is a big problem with PHP and MySQL. I have to get data out from MySQL through PHP, then put them into a XML file. After that, i use javascript to put XML data into webpages. It seems to be a roundabout approach.

I tried a XML pipe yesterday. It’s a php file. Using a form to send parameters to that file and get XML form data back. Then show them on the page. It worked fine. But, if there are lots of data to deal with, that pipe would be really really complex. It have to handle all kinds of data and transform them into XML file.

And now, i am looking for a way to get WP data. Huge amount of codes to read… See u next decade!
