Hmm, so in tree terms, each node has two distinct types of children, only one of which can have their own children. That sounds more ambiguity-introducing than helpful to me, but that’s just a matter of taste. Can you do lists in XML as well?
Maybe I just like the idea of a closing tag being very specific about what it is that is being closed (?). I guess I’m really not sure, but it does feel nicer to my brain to have starting and closing tags and distinguishing between what is structure, what is data, what is inside where.
My peeve with json is that… it doesn’t properly distinguish between strings that happen to be a number and “numbers” resulting in:
I actually don’t like the attributes in xml, I think it would be better if it was mandatory that they were also just more tagged elements inside the others, and that the “validity” of a piece of xml being a certain object would depend entirely on parsing correctly or not.
I particularly hate the idea of attributes in svg, and even more particularly the way they defined paths.

That’s kind of what I was getting at with the mental scoping.

Is that implementation-specific, or did they bake JavaScript type awfulness into the standard? Or are numbers even supported - it’s all binary at the machine level, so I could see an argument that every (tree) node value should be a string, and actual types should be left to higher levels of abstraction.

I agree. The latter isn’t even a matter of taste, they’re just implementing their own homebrew syntax inside an attribute, circumventing the actual format, WTF.
I don’t mind xml as long as I don’t have to read or write it. The only real thing I hate about xml is that an array of one object can mistaken for a property of the parent instead of a list
YAML is good for files that have a very flexible structure or need to define a series of steps. Like github workflows or docker-compose files. For traditional config files with a more or less fixed structure, TOML is better I think
It is very cool, specifically as a human readable mark down / data format.
The fact that you can make anything a tag and it’s going to be valid and you can nest stuff, is amazing.
But with a niche use case.
Clearly the tags waste space if you’re actually saving them all the time.
Good format to compress though…
I disagree, with a passion.
It is soooo cluttered, so much useless redundant tags everywhere. Just give JSON or YAML or anything really but XML…
But to each their own i guess.
To each their own indeed.
;)
I think we did a thread about XML before, but I have more questions. What exactly do you mean by “anything can be a tag”?
It seems to me that this:
<address> <street_address>21 2nd Street</street_address> <city>New York</city> <state>NY</state> <postal_code>10021-3100</postal_code> </address>Is pretty much the same as this:
"address": { "street_address": "21 2nd Street", "city": "New York", "state": "NY", "postal_code": "10021-3100" },If it branches really quickly the XML style is easier to mentally scope than brackets, though, I’ll give it that.
Since XML can have attributes and children, it’s not as easy to convert to JSON.
Your JSON example is more akin to:
<address street_address="21 2nd Street" city="New York" ...></address>Hmm, so in tree terms, each node has two distinct types of children, only one of which can have their own children. That sounds more ambiguity-introducing than helpful to me, but that’s just a matter of taste. Can you do lists in XML as well?
No arrays are not allowed. Attributes can only be strings. But the children are kind of an array.
I’m not sure now that I think about it, but I find this more explicit and somehow more free than json. Which can’t be true, since you can just
{"anything you want":{...}}But still, this:
<my_custom_tag> <this> <that> <roflmao> ...is all valid.
You can more closely approximate the logical structure of whatever you’re doing without leaving the internal logic of the… syntax?
<car> <tyre> air, <valve>closed</valve> </tyre> <tyre> air, <valve>closed</valve> </tyre> <tyre> <valve>open</valve> </tyre> <tyre> air, <valve>closed</valve> </tyre> </car>Maybe I just like the idea of a closing tag being very specific about what it is that is being closed (?).

It works, but I consider that truly ugly. And also I don’t understand because it would have been trivial to do something like this:
<path><element>data</element><element>data</element></path>That’s kind of what I was getting at with the mental scoping.

YAML for human-written files, JSON for back-to-front and protobuf for back-to-back. XML is an abomination.

Having an easy on the eyes markdown that is also easy to parse would be cool.
But YAML does these things:

which are not excusable, for any reason.
