Do people still use XML?
-
XML is widely used. And, it's often a lot more convenient than JSON, since you can create a DTD that lets the parser do a lot of the grunt work for you. I use it all over the place. I only use JSON if it's already part of the protocol of a device I'm talking to or it's stuff related to talking to Javascript in a browser.

I mostly use JSON these days for data interchange, but I hear you about typing. That being said, there's a spec for JSON schemas, and many engines already support validation using them. I don't use them myself. In the real world, most JSON is machine generated, which means it doesn't necessarily need heavy validation unless its coming from somewhere external (to avoid possible exploits)
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

For me lots of it is user configuration, or data from external devices or servers, none of which can be assumed to be even reasonably correct. And, ultimately, it all really probably should get good validation. If your program croaks because of an error in another program, that's not a good thing.

that's what error handling is for. Validation just lets you throw sooner. A lot of times that's not even necessary.

I can't use JSON for rendering a parse tree because JSON does not preserve the order of subelements and because of the way multiple values are presented it gives json problems. XML can do it, because XML preserves element order and an element can be present more than once within its parent container. But I don't want to bother if everyone hates XML. What would you do?

I would not use XML if there was serious volume involved, I've seen systems fail using xlm when attempting to transfer gb between systems. As others have said use the correct tool for the job no matter whet the "popularity" you perceive is.

For what it's worth, XML has been my preferred persistence format for a long time. It makes it relatively easy to manage arbitrary structure and schema changes, UNICODE, and so on. It also translates well to other programming environments and languages, given that support is fairly ubiquitous. It's no longer "flavor of the month", but it has the advantage of... it works.

If you need to guarantee that your objects stay in order, use XML. JSON is subject to the engine that's parsing it, where XML is - well - XML. The only thing I think most real programmers hate is any form of visual basic.

That sounds like a challenge :laugh:. Let's see.
- Windows installer and writing install packages for it
- Writing Windows device drivers
- Writing Windows device driver installers
- Creating Windows install images when a new revision of the OS comes out
- The MSDN web site, which Microsoft redesigns to obscure the fact they're removing content so they don't have to support it
and that's just the crap I can think of associated with Microsoft and Windows. If I got started on software management in a hardware-centric company, two things would happen. One, I'd probably exceed Chris' message length limit, and two my ass would be terminated with extreme prejudice.

There’s a way around the big-ass file problem, but it comes with restrictions. A few months ago, I wrote some code to load files that were as large as 8gb. It could probably go larger, but that’s the largest file I had.

The "job" is undefined. I'm making an API. Anyway, I'm not sure I'm going through with this bit. Besides I have other stuff to work on that has taken precedence.

I *always* chunk, absent the narrow case where it doesn't make sense to.

System was totally unwieldy and got canned before it was completed. XML was never used again as a transfer medium.

Prolly stating the obvious, but can you package subelements as items in an array? /ravi

they need names. i could, but the resulting json isn't worth it [ {a: b}, {c: d} , {e: f} ] sucks, you know? better to just use xml

Use PostScript. It's like a version of XML that hasn't had its bollocks lopped off.
