Predominantly FALSE. It is incorrect when someone makes such a definite judgement about area they don't know well. Such judgement only reflects their insufficient grasp of the subject. If someone stills doesn't know it, the FXSL library (written entirely in XSLT) implements so much of "higher math", that it has been critisized by some people for this. Here are just some examples, quoted from http://www.idealliance.org/papers/extreme/proceedings/html/2006/Novatchev01/EML2006Novatchev01.html#t5 : Numerical differentiation Numerical integration Limits of sequences Trigonometric functions, hyperbolic trigonometric functions Logarithmic and exponentiation functions Inverse trigonometric functions Roots of a continuous function with one real variable Random numbers Random numbers with specified distribution Randomisation of lists/node-sets There is a lot more "advanced functionality" implemented in FXSL, that is typically not provided by an imperative language or is not easier to implement in imperative settings: Higher-order functions Functional composition Partial application, currying Dynamic creation of functions Generic iteration Generic recursion over lists Generic recursion over trees Mapping, zipping, splitting, filtering of lists Generic binary search in Ordered Generic sort in Ordered A lot of string procerssing, such as spelling-checking, concordance building, finding anagrams, ..., etc. General graph traversal. Genaral LR(1) parsing. Lastly, the statement that compared to XSLT Java is "a higher level language (such as Java) ", really made my day :) -- Cheers, Dimitre Novatchev --------------------------------------- Truly great madness cannot be achieved without significant intelligence. --------------------------------------- To invent, you need a good imagination and a pile of junk ------------------------------------- Never fight an inanimate object ------------------------------------- You've achieved success in your field when you don't know whether what you're doing is work or play On Mon, Dec 1, 2008 at 7:38 AM, Costello, Roger L. <costello@m...> wrote: > > Hi Folks, > > I am exploring the idea of "do all application coding in the XML languages." > > Here is a response from a colleague: > > "... in general XSLT is cool but limited.
