As someone who is only a debutant in php but not bad in xsl, this looks like a great idea. I don't see why it would not be a great idea even for an expert in php. The article is already 10 years old, so I wondered if there are any disadvantages to this way of doing things as I have not read of such a technique before.
Time has shown that you cannot rely on the XSL/T processor in the 
browser (things may be better now though), so you have to do the 
XML->HTML conversion step in the server.  This step can be more or less 
expensive and also takes time, and web sites with high loads may not 
want to do that.

Also note that most XSL/T processors cannot work in streaming mode where 
the output is being generated _while_ the XML is still being read 
causing a delay until the whole input has been read.

I am not saying that XSL/T is not a viable technology.  It is perfect 
for generating data and converting it to HTML or fixed length text-files 
(ok, only semi-perfect for that), but that it has a somewhat invisible cost.
