RE: [WSG] Experimentations in XSLT
What is the cms that you are trying? Is it mosxml? I've been looking into that one and would be interested in your opinion. I haven't gotten it to work but I think the product looks promising.

Re: [WSG] Experimentations in XSLT
Most XSLT users process data server-side and then send the result of the transformation to the client. This is a safer approach than sending XML and XSLT to the client. Yeah, this is absolutely right. The typical xml publishing flow looks something like this, [xml source (docbook/openoffice/xhtml)] feeds into [business logic xslt] which feeds into [web presentation logic xslt] or [print presentation logic xslt] or [pda presentation logic xslt] and then it's sent to the outside world. Typically this type of flow from one bit of xslt to the next is called a "pipeline", and there's software to assist you in creating these and aggregating the results. You can construct pipelines in any language by pushing the output from one transformation into another, but these frameworks will cache each stage of the pipeline and skip the regeneration if the files haven't changed, and other features to ease development. Specifically, there's Apache Cocoon which has been in heavy use around the world for years. I've used it in a few commercial projects and it's one of those frameworks that makes the job so much easier. There's my ripoff of Cocoon in PHP called Phpilfer, http://holloway.co.nz/phpilfer which has some (in my opinion) important technical changes to make it faster than Cocoon (although less XML'y). Phpilfer isn't ready for production use yet but I'm putting out a site in it over christmas so that'll be a good test. Mostly, the benefit of XSLT is that you start with these media-independent source files that you can convert to web, print, voice, xbrl, rss, any format, and it's a well-tested tech that people are using every day. If you're a publishing house, or you have a lot of content on your website, then these highly structured media-independent source files are your gold. People should be more wary of producing source documents, spending weeks editing them, and then locking them up in a loosely structured format (like MSWord, PDF) that other software can't easily get into. XML publishing is about fixing all that. There's this mediocre presentation for the Wellington PHP user group a few years ago about XML publishing, http://holloway.co.nz/wellypug/publishing/ Jonathan T.

Re: [WSG] Experimentations in XSLT
Hi Jonathan, Most XSLT users process data server-side and then send the result of the transformation to the client. This is a safer approach than sending XML and XSLT to the client. XSLT is a wonderful technology. A while back we did some XML and XSLT training for the Canadian government. For those that want a hands on approach to learning XSLT, here are a few labs. Lab 4 lets you practice XPath and Lab 5 lets you practice XSLT. Here is the link: http://belus.com/training/ Also, Jonathan, I had a look at your XSLT. You can optimize it a bit if you replace several with or . Regards, -Vlad http://xstandard.com XStandard Development Team - Original Message - From: "Jonathan T.

[WSG] Experimentations in XSLT
Good afternoon Recently, after the pursuit of a site that does conform to XHTML 1.1 and CSS2, I became very interested in the XSL/XSLT language, since my site has a XML CMS back end already. I began to look at ways to cut out the PHP step. My experimentations have proved to be very interesting, with 2 caveats: 1.) Obviously 2 pass processing doesn't work. Catching PHP embedded in the source XML becomes impossible. At this time, I don't have a fix for this. 2.) Firefox (in fact all gecko based browsers) do not support my method of embedding HTML in XML... results are interesting, but expected. Opera doesn't like this method at all, and IE6 displays perfectly. Since this list is standards based, and I've yet to see any real writeup about XSLT and what it is capable of, I figured a would share what I found with all of you. More information about what I did is available here: http://jtsage.com/apathy/archives/2004/12/08/xslt-part-1/ and here: http://jtsage.com/apathy/archives/2004/12/09/xslt-part-2/ If anyone has any information on how to fix #2, I'd also love to hear it.
