What is XML ?
XML (Extensible Markup Language) is a markup language that is used to encode and share documents on the web. It is a flexible and widely-used language that is easy to read and write, and can be used to store and transport data between different applications and systems.
XML uses tags to define the structure and content of a document. Each tag represents an element, and the elements can be nested within each other to create a hierarchy of data. In addition to the elements, It’s also allows the use of attributes to provide additional information about the elements.
Here’s an example of a simple (Extensible Markup Language) document that contains information about a book:
XML Code
<?xml version="1.0" encoding="UTF-8"?>
<book>
<title>Java Programming</title>
<author>John Smith</author>
<publisher>Publisher ABC</publisher>
<price currency="USD">29.99</price>
</book> In this document, we start with an XML declaration that specifies the version of XML being used and the character encoding of the document. We then define a book element that contains four child elements: title , author , publisher and price.
The title , author , and publisher elements contain text data that describes the book. The Price element contains both text data (the price of the book) and an attribute (currency) that specifies the currency in which the price is expressed.
It can be used in a wide variety of applications, including web services, configuration files, and data interchange formats. It is widely supported by many programming languages, and there are numerous tools and libraries available to help parse and generate XML documents.
