I have a home-grown PHP framework that I use for rapid site production for my clients. I've been fascinated with XML/XPath/XSLT for quite a while and with the new XML transformation capabilities packaged with PHP5 I have decided to rewrite the framework using PHP's DomDocument and XsltProcessor classes. Most of the conversion has gone smoothly, but I have been running into problems combining multiple XML documents and running them through the XsltProcessor. The system used to use a custom-written templating engine that breaks down the XHTML and CSS into Site, Module, and View levels that nest into one another. I have a whole collection of classes that are used as Components (basically classes that handle data-binding from the UI to the Model and the Database that can render themselves into XHTML). So each of the Site, Model, and View can contain Components, and all of the above can contain links to external CSS files. I am basically going through and replacing all of the render() methods and HTML template files with XML and XSLT files. There are multiple steps to the rendering process, since a finished HTML doc can only have one <head> element which must contain all of the <link>s to the CSS files, which are kept locally by the renderable classes. There is a single CSS file to go with the Site, there is one for each Module, and one for each View, but if any of these contain components then the HTML for that must be sucked in along with the CSS link. All of the <link> elements need to end up in the <head> block in the finished document, while the cascading HTML snippets need to end up in the <body> block. I start by running an XSL Transformation on the Site to pull in the Site-level Components, then do the same individually for the requested Module and View. Right now I am leaving placeholder tags in the resulting HTML docs so that they can be cross-matched when it is time to blend these three files into the final page. This is where I am stuck. Of course I could always use PHP string-replacement functions to cut the files together, but I'd prefer to use the same method all the way through the rendering (transformation) process. Is there anybody out there with experience in this that might be able to point me in the right direction?
