If you think xml/html is ok as replacement for text then we have no significant 
disagreement.
That is after all the main point of
http://blog.languager.org/2012/10/html-is-why-mess-in-programming-syntax.html
viz that program texts would be better off replacing text with hypertext.
[that html = Hyper Text Markup Language adds to the snark; but does not change
 the message]

The key difference between all the above and state of art in programming
languages is that lexing, parsing is in principle and possibly in practice
'outsourced' to generic XML tools.
With programming languages these are in silos in the innards of the language
implementation.
And so people typically studying compilers etc come to think of lexing and
parsing as important/key activities....
except for a few outliers like Marvin Minsky:
