1. I don't need to write an XML parser - people have already
packaged them up in APIs ready to use. That makes writing the
editor in particular easier, and means that the compiler or
interpreter only has to handle one level of parsing.
2. These parsers already handle character set conversion - I don't
need to worry about ASCII, UTF-8, etc as that's the XML parsers
job.
3. In reality, XML need be no more complex than LISP-style
parenthesised expressions. Remember, I'm proposing a marked-up
text source code, having rejected the virtual AST version. That
means the bulk of the 'code' will be plain text embedded in XML.
XML provides a clear distinction between markup and text which
LISP does not - the end result would be that an equivalent in LISP
would need quoted strings for the text and would end up just as
complex as XML.
Let's compare...
(def) " " (id "test") " (" (id "x") ")"
(indent
(print) (lit-str "x squared is : ") "," (id "x") (mul) (id
"x")
)
with...
<def/> <id>test</id> (<id>x</id>)
<indent>
<print/> <lit-str>x squared is : </lit-str>, <id>x</id> <mul/>
<id>x</id>
</indent>
There's really not much to choose between them, but I prefer the
latter overall.
