XML (Extensible Markup Language) is a text-based markup language used for storing and organizing data, distinct from HTML which is for displaying data. This tutorial covers XML basics, advanced features, and tools, detailing how XML can simplify web document creation, facilitate information exchange, and support data management. Additionally, it explains XML syntax, processing instructions, encoding, schemas, and the tree structure of XML documents.

- 2. Introduction to XML • XML stands for Extensible Markup Language and is a text-based markup language derived from Standard Generalized Markup Language (SGML). • This tutorial will teach you basics of XML. The tutorial is divided into sections such as XML Basics, Advanced XML and XML tools. Each of these sections contain related topics with simple and useful examples. • XML tags identify the data and are used to store and organize the data, rather than specifying how to display it like HTML tags, which are used to display the data. • XML is not going to replace HTML in the near future, but it introduces new possibilities by adopting many successful features of HTML.
- 3. XML Usage • XML can work behind the scene to simplify the creation of HTML documents for large web sites. • XML can be used to exchange the information between organizations and systems. • XML can be used for offloading and reloading of databases. • XML can be used to store and arrange the data, which can customize your data handling needs. • XML can easily be merged with style sheets to create almost any desired output. • Virtually, any type of data can be expressed as an XML document.
- 4. What is Markup? XML is a markup language that defines set of rules for encoding documents in a format that is both human-readable and machine-readable. So what exactly is a markup language?Markup is information added to a document that enhances its meaning in certain ways, in that it identifies the parts and how they relate to each other. More specifically, a markup language is a set of symbols that can be placed in the text of a document to demarcate and label the parts of that document. How XML markup looks? <message> <text>hello, world </text> </message>
- 5. XML - Syntax A simple syntax rules to write an XML documents: <?xml version =“1.0”?> <contact-info> <name>Assignment help</name> <company>Augment Systems pvt. Ltd></company> </contact-info>
- 6. XML - Processing • Processing instructions (PIs) allow documents to contain instructions for applications. PIs are not part of the character data of the document, but MUST be passed through to the application. Syntax: <?target-instructions?> Where: • target - identifies the application to which the instruction is directed. • instruction - it is a character that describes the information for the application to process.
- 7. XML - Encoding Encoding is the process of converting unicode characters into their equivalent binary representation. When the XML processor reads an XML document, it encodes the document depending on the type of encoding. Hence, we need to specify the type of encoding in the XML declaration. Syntax: <?xml version =“1.6” encoding =“UTF-8” standalone= “no”?>
- 8. XML - Schemas XML Schema is commonly known as XML Schema Definition (XSD). It is used to describe and validate the structure and the content of XML data. XML schema defines the elements, attributes and data types. Schema element supports Namespaces. It is similar to a database schema that describes the data in a database. Syntax: <xs:schema xmlns:xs = http://www.w3.org/2001/XMLSchema>
- 9. XML - Tree Structure An XML document is always descriptive. The tree structure is often referred to as XML Tree and plays an important role to describe any XML document easily. The tree structure contains root (parent) elements, child elements and so on. By using tree structure, you can get to know all succeeding branches and sub-branches starting from the root. The parsing starts at the root, then moves down the first branch to an element, take the first branch from there, and so on to the leaf nodes.
