SAX-like apps in PHP

Now on IBM developerWorks: SAX-like apps in PHP -- While there is no official implementation of the Simple API for XML (SAX) in PHP, PHP does provide a SAX-like method for working with both local and remote XML files. In this article, author Nicholas Chase shows you how to work with XML files in PHP by building and setting handler functions and creating a parser. He demonstrates SAX in PHP with a page-building exercise in which he crafts a page based on the result of an Amazon Web Services query.
