Today I've found another new language (working draft in fact). It's
an XML Pipeline Language.
XProc: An XML Pipeline Language, a language for
describing operations to be performed on XML documents.
An XML Pipeline specifies a sequence of operations to be performed on zero or
more XML documents. Pipelines generally accept zero or more XML documents as
input and produce zero or more XML documents as output. Pipelines are made up of
simple steps which perform atomic operations on XML documents and constructs
similar to conditionals, iteration, and exception handlers which control which
steps are executed.
An experience shows a process of language invention is an essential part of
computer industry from the very beginning, however...
I must confess I must be too reluctant to any new language: I was happy with
C++, but then all these new languages like Delphi, Java, C#, and so many others
started to appear. It's correct to say that there is no efficient universal
language, however I think it's wrong to say that a domain specific language is
required to solve a particular problem in a most efficient way.
And now a question to the point: why do you need a new language for describing
operations to be performed on XML documents?
