XML and XSLT is still very common in companies that send data to county recorder's offices. Things like real estate document recording. The PRIA spec is all XML.
I used XSLT back in the day to rip excel spreadsheets and write (nonstandard) InDesign Markup Language files for a car price guide. It was HELL! I felt like I was ready to navigate the galaxy after that. I then used the same technique to rip data out of poorly-formatted data collection sheets and dump them into a properly normalized database for the city, that was a real cool project. We had like 8,000 data entry sheets that were designed by the office manager (ie, no consideration to processing the data later) and all but maybe 50 we were ultimately able to parse automatically.
I had to use XML for a DHL Germany project.
Many large companies still use XML. You can learn on the job for this one guys.
(btw I'm a Full stack JS dev)
XML is a very powerful technology when combined with XSLT (which is a turing complete programming language) and XPATH (the most flexible way to traverse any document) since XML can be transformed to anything you can imagine, HTML, other XML, any kind of scripts or even notation like JSON... which by the way doesn't fully replace XML ecosystem at all, simply because XML describes nodes and JSON describes objects which are different programming paradigms. Transporting data with XML is not it's main feature (although it can get really compact)... transformation really is!... In fact, I'm preparing this framework with XML and XSLT on the frontend (you can use JSON or XML as transformation syntax so you can consume any existing API) and the best is that it will be release soon... so please let me know if there's someone who can be of help in this project. Thanks in advance!
i’m tryna build off odoo and create a xml framework in python with websocket dom modifications since JS wants to monopolize the damn internet
Only learning xml because of work. Surprisingly still used in a lot of enterprise/finance erp/oms systems. If you’re learning APIs (soap and rest), working knowledge is enough and the rest you can search on the go.
DITA is a defacto standard for structured documentation in the technical communication field. It's a form of XML.
Today you have to know JSON if you are going to work with API and integration, but you are not complete if you don't know SOAP, XML & XSLT even of you develop or work with a company that has only canonical JSON in-house, sooner or later you will have to talk to an external XML based system, there is simply no getting around it.
I work almost every day with XML data. I am working for an e-commerce platform. Most of our suppliers provide their product data using XML and CSV. Our EDI team transforms those data to BMEcat, which is also an XML based data format. But learning just XML has no meaning. It's like learning CSV or JSON. These are just data exchange formats. It will be much better and useful to learn how to parse, modify and transform these data formats using python, php, java etc..
hey! im currently studying this for a course. thanks for the insights uncle stef 🖖
Welcome! 🖖
I had to learn XSLT to update and maintain a contract (PDF) generation system... felt weird, but it works. It's easy to learn when you land at a place where they use it. In my opinion, just being aware that it exists is good enough.
XML is widely used in the humanities (TEI). JSON is useless for texts. A lot of file formats are XML-based. SVG is XML., .docx is XML, .KML (.KMZ) is XML etc. etc.
It's astonishing that you could discuss XML and XSLT without understanding their primary purpose. In many industries xml is the storage and editing medium for technical documentation. There are widely used standards such as S1000D and DITA that are built on XML.
JSON is not a replacement for XML in that environment.
Also there is a real shortage of developers who really know this stuff.
So true, there are many ISO standards like ISO-20022 for financial institution, SO/IEC 29500-1:2011 Open Office that are all XML based
@@luisvillar8320 even microsoft's offficr files rely on xml since office 2007 came out. Very interesting stuff.
It is not legacy. XSLT can turn JSON and XML to ANY format. It's not as widely used but extremely important in data transformation and very powerful. Also way faster than expected.
Currently applying for SAP dev and support position. XML, XSLT and XPath are must have tools there. Also used XPath for mobile automation before. Thanks for the video.
Some protocols like OPCUA are also using XML to describe sensors or a PLC.
Heritage institutions around the world use XML and XSLT extensively for metadata transfer, processing, and storage. JSON is used for APIs. So yes. It's specialized.
XSLT is awesome for transforming data in a functional way. Only don't use the for loop piece. And they were reticent about adding it too.
This might be off topic, but I heard that some people are still using the BASIC programming language for some things. There's a whole community of people using it and they stick by it.
Many things were built on vb6 by financial institutions and some were hesitant to phase out their "working" systems. Nowdays COMs are not as reliable as newer tech. There's nothing wrong with using Basic, COBOL and other languages... the problem is that a lot of these systems have reached Software Entropy and are now very expensive to replace.
I would only learn xml if the job asked for it. At my old job we used xml over json to get data for the e-learning courses we developed. We where only using it because our stakeholder wanted us to. Mind you our stakeholder wouldnt have noticed is we used json instead they just wanted us to stick with an xml standard.
XML is often used with Java in Enterprise systems
Kind of misses the point of markup languages. If you need to markup documents, the answer is obvious: XML. HTML5 is basically XML and XHTML5 explicitly so.
XSL(T) is such a superb language/ruleset which json can't replace. The XSL-T(T) Transform doesn't exist i JSON universe. As for transport data anyway will do I guess :)
Last time i worked with XML and XSLT, was 5y ago... nowadays is JSON!
That’s like saying SQL is legacy; don’t learn it; APIs use mostly JSON.

JSON is extremely fragile. People can't just add more data to a transmission without a great deal of orchestration, which isn't required with XML / XSLT. JSON is certainly lighter weight, but you are rarely going to see a difference unless you are transmitting A LOT of data (which increases the fragility of JSON)..
I have a question since you are wealthy and your like the only person I could imagine even close to answering this. Is school worth the time after 6/7th grade now I know unless I want to work at space X I don't need to know 90% of the things you learn in 8th grade (I am in 8th) I am more interested in $ and coding or gaming than school what is your opinion on this should I argue with my mother for hours until she understands or waste my time learning things I don't need to learn in my opinion
It depends on where you live honestly. In some places, a degree is more important than experience. May I know where do you live?
In which country that is.
@@yourfellowhumanbeing2323 sorry I didn't see this earlier I'm from New York
The mind is a complex thing. School helped me broaden what I once thought was right for me. Being surrounded by other people seeking knowledge fuels your own curiosity. Many things people would tell me that were useless to learn at college, have come in handy since I started working as a software engineer. Knowledge work can take you through many different paths. College was worth it for me. I found a cheap way to get my education and moved on. Your path may be different, I can only tell you what worked for me. I'm from México, I went to highschool in california, returned to México the same year I graduated from HS to get an ingineering degree at an almost free state college in my home town and I'm now living a very good debt free life.

+1 for JSON -1 for XML and the whole validation process.
Validation is important even in JSON. The fact that it is required in XML makes it ideal for applications at scale.
😍😍❤️❤️💙💙

No you should not. If a tool or process requires XSLT, it is fundamentally broken. There is no valid reason to ever use this parody of a language.
