Au contraire: the more you understand and use XSLT, the more you hate it. People who don't understand it and haven't used it don't have enough information and perspective to truly hate it properly. I and many other people don't hate XSLT out of misunderstanding at all: just the opposite.
XSLT is like programming with both hands tied behind your back, or pedaling a bicycle with only one leg. For any non-trivial task, you quickly hit a wall of complexity or impossibility, then the only way XSLT is useful is if you use Microsoft's non-standard XSLT extensions that let you call out to JavaScript, then you realize it's so easy and more powerful to simply do what you want directly in JavaScript there's absolutely no need for XSLT.
I understand XSLT just fine, but it is not the only templating language I understand, so I have something to compare it with. I hate XSLT and vastly prefer JavaScript because I've known and used both of them and other worse and better alternatives (like Zope Page Templates / TAL / METAL / TALES, TurboGears Kid and Genshi, OpenLaszlo, etc).

>My (completely imaginary) impression of the XSLT committee is that there must have been representatives of several different programming languages (Lisp, Prolog, C++, RPG, Brainfuck, etc) sitting around the conference table facing off with each other, and each managed to get a caricature of their language's cliche cool programming technique hammered into XSLT, but without the other context and support it needed to actually be useful. So nobody was happy!
>Then Microsoft came out with MSXML, with an XSL processor that let you include <script> tags in your XSLT documents to do all kinds of magic stuff by dynamically accessing the DOM and performing arbitrary computation (in VBScript, JavaScript, C#, or any IScriptingEngine compatible language). Once you hit a wall with XSLT you could drop down to JavaScript and actually get some work done. But after you got used to manipulating the DOM in JavaScript with XPath, you being to wonder what you ever needed XSLT for in the first place, and why you don't just write a nice flexible XML transformation library in JavaScript, and forget about XSLT.
Counterpoint: the more I used XSLT, the more I liked it, and the more I was frustrated that the featureset that ships in browsers is frozen in 1999
You should really try some of the modern alternatives. Don't let Angular and React's templating systems poison you, give Svelte a try!
Even just plain JavaScript is much better and more powerful and easier to use than XSLT. There are many JavaScript libraries to help you with templates. Is there even any such thing as an XSLT library?
Is there some reason you would prefer to use XSLT than JavaScript? You can much more easily get a job yourself or hire developers who know JavaScript. Can you say the same thing for XSLT, and would anyone in their right mind hire somebody who knows XSLT but refuses to use JavaScript?
XSLT is so clumsy and hard to modularize, only good for messy spaghetti monoliths, no good for components and libraries and modules and frameworks, or any form of abstraction.
And then there's debugging. Does a good XSLT debugger even exist? Can it hold a candle to all the off-the-shelf built-in JavaScript debuggers that every browser includes? How do you even debug and trace through your XSLT?
I think the fundamental disconnect here is that you're assuming that I am a developer. I'm not, I'm a lousy developer. It's not for lack of trying, programming just doesn't click for me in the way that makes learning it an enjoyable process.
XSLT is a good middle ground that gave me just enough rope to do some fun transformations and put up some pages on the internet without having to set up a dev environment or learn a 'real' programming language
It is always correct to tell someone they are wrong for liking something, and doing so is how we keep HN great.
Well said. I wrote an XSLT based application back in the early 2000s, and I always imagined the creators of XSLT as a bunch of slavering demented sadists. I hate XSLT with a passion and would take brainfuck over it any day.
Hearing the words Xalan, Xerces, FOP makes me break out in a cold sweat, 20 years later.
