Need to manipulate XML document trees, but don't have the DOM extension compiled into your PHP build? Take a look at XMLTree, a PEAR class that allows you to create and manipulate XML document trees without requiring the PHP DOM extension.
And that's about it for this article. Over the last few pages, I showed you how you to build an XML document tree even if your PHP build doesn't support the XML DOM, via the free add-on XMLTree class from PEAR. I showed you how to programmatically create an XML document, how to construct root and child nodes and attributes, how to remove nodes from an existing document tree, and how to convert your existing XML files into XMLTree-compliant format Finally, I wrapped things up with a composite example that demonstrated a practical, real-world use for all this code - converting the data in a MySQL database into XML, and transforming it for use on a Web site with PHP and XSLT.
All this is, of course, only the tip of the iceberg - there are an infinite number of possibilities with power like this at your disposal. To find out what else you can do with XML and PHP, I'd encourage you to visit the following links:
