Hello,
I'd like to learn the XML language
XML isn't actually a language (apart from the Declaration Syntax);
it's a specification for a syntax to write markup languages of your
own.
(in particular am interested in DTD,
XML Schema and styles). Do you have some suggestion useful to start? I
see there are many books but don't know how to start. I began to read
one of this publication (the famous 1000 pages omnicomprensive) but it
seems to me a bit dispersive.
The best approach is to learn something about the use of markup first,
so that you understand why you might want to do such a thing. The TEI's
famous chapter "A Gentle Introduction to XML" is a good starting-point:
http://www.tei-c.org/P4X/SG.html
You may then want to decide the kind of things you want to use XML for.
Traditionally it's been used for text document for publication, but
outside the publishing field its primary use is as a carrier of
information between disparate systems (messages, data transfer, data
specification, etc). The way in which markup is used for these two
classes of application is radically different, so what you decide to
learn will largely depend on your field of work.
