Answer 1

XML is very similar to HTML, except that you can make up whatever tags you want. So, if you were cataloging all your CDs, you could do it in XML like this:


Beatles


Pearl Jam





So, if you are familiar with HTML you will see how the syntax is exactly the same, but with HTML you have to work with predefined tags, and with XML, you make up tags to fit your project. XML is just a way of organizing your data, and you have a lot of freedom in how you want to do it. That freedom is what gives XML so much versatility.

I hope this helps. I know it's not very in depth, but that's the basic gist of XML. Check out that W3Schools link, and you'll learn more there.

Answer 2

XML is a markup language for information containing based counsel. based counsel consists of the two content cloth (words, photos, and so on.) and a few indication of what function that content cloth performs. In HTML, the two the tag semantics and the tag set are mounted. XML specifies neither semantics nor a tag set. XML became created so as that richly based information would want for use over the cyber web. the only achieveable concepts, HTML and SGML, are no longer functional for this objective. unquestionably, HTML comes certain with a set of semantics and does not grant arbitrary shape.

Answer 3

XML on its own is nothing. It has no powers, no controls, no formatting nothing.
XML is just a way of describing data.
Take this date
12122007
You only know it is a date because I have just told you that it is a date. But what else do you know about this date?
Nothing.
Now look at this date with XML.

12
12
2007

See you now know so much more about the data.
So why do people shout so much about XML?
Well when put it together with DTD (XML layout definition)
and XSL (XML style and formatting) you can produce a dynamic web page to present your data. And you have used all the tags that you have created.
Here is a tutorial with more information.

Answer 4

XML is a standardized markup language that can be used to define data or other markup languages, such as XHTML which is a XML implementation of HTML [1]. In and of itself XML is capable of very little, however, the fact that it is a standard means to format data means that it can be used in very powerful contexts and also provides more human readable means of exchanging or saving data between applications.

Answer 5

why a project on XML?

basically, do a project using JAva and then use XML to specify features, field names, parameters, settings etc. This is what XML is used for.

I would be surprised if you could write a project in XML. If yes, it would be a task at best

search google with keyword "XML" and you should be on the way

Answer 6

It is a open source format that many word processors are now using. It looks like HTML but is much more advanced. OpenOffice has used it for a long time and the latest version of Microsoft Office uses it.
