Subject: [xsl] xslt critique From: "bryan" <bry@xxxxxxxxxx> Date: Fri, 26 Jul 2002 11:25:00 +0200 |
http://www.cs.uu.nl/~visser/ftp/LVV02.pdf has an article about strategic programming, included in it is a critique about XSLT, I was interested in what people on the list might feel about these criticisms? I'm finding some of the complaints not sensible although this is probably because I have trouble at times with too much abstraction. Quote from article: "At least two ingredients of strategic programming are truly missing. There is no notion of partiality. Templates simply apply or not. Any kind of backtracking model is not available. More seriously, XSLT templates are not first-class. As discussed for basic rewriting and tangled traversal in functional programming, this leads to tangling traversal control and computation. In fact, XSLT even lacks appropriate type-specific operations since one cannot even easily pattern match on elements of a certain structure. This was observed in [28]. The resulting inappropriateness of XSLT for intentionally generic document transformation is discussed and illustrated in [41]. Besides, an XSLT-like language design is hardly accessible for typeful (generic) transformations, although there are some theoretical results on typing essential fragments of the XSLT expressiveness..."
