That seems so limiting like having an emotional vocabulary of happy, sad

XML makes me sad and angry.

Well, there are different aspects to XML.

There really are people who think that XML databases are a good thing
because they allow you to put data into storage without having to
model the data, because "everybody" knows that modelling data is too
hard. Of course, there's that little matter of getting data out
again, but they have hopes that following conventions for positioning
some key tags will lead to a good result. These are the same people
who used to believe that storing name/value pairs in database tables
was a good thing. I can understand that that would make you
unhappy.
These people are ignorant of data fundamentals. EAV justification of
XML use is just dumping a problem on the top of the other.


There's also the niggling detail that the standard XML query language
can return different results depending on whether or not it's a schema-
aware implementation, and I can understand that that would make you
unhappy.

But why would you be unhappy about XML as a transport format? It's
mostly an improvement over what we had before - CSV files, binary
formats, etc.
What advantage of XML as a transport format do you see over let's say
a CSV file with an integrated header?
