XML has several key features: 1. Simplicity: It is easy to understand and read. 2. Extensibility: You can define your own tags. 3. Structure: Data is stored in a hierarchical format. 4. Platform independent: It can be used across different systems. 5. Human and machine-readable: XML is easily readable by both humans and machines. 6. Self-descriptive: Tags describe the data they enclose.

  <name>John</name>

XSLT (eXtensible Stylesheet Language Transformations) is a language used to transform XML documents into other formats, such as HTML, plain text, or other XML structures. It defines a set of rules to match elements in the source XML and output the desired format. XSLT allows for dynamic transformations and is widely used in data conversion and web development. 

 <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <html>
      <body>
        <h1><xsl:value-of select="note/heading"/></h1>

XML Namespaces are used to avoid naming conflicts when combining XML documents from different sources. A namespace is a way to uniquely identify elements and attributes by associating them with a URI. This allows for the reuse of elements without conflict. Namespaces are defined using the `xmlns` attribute. 

 <root xmlns:ns1="http://example.com/ns1" xmlns:ns2="http://example.com/ns2">
  <ns1:element>Value1</ns1:element>
  <ns2:element>Value2</ns2:element>

XML stands for eXtensible Markup Language. It is a markup language designed for storing and transporting data. The primary purpose of XML is to allow data to be shared across different systems, especially via the internet. Unlike HTML, XML is focused on data representation rather than presentation. It is both human-readable and machine-readable.

XML (eXtensible Markup Language) is used to store and transport data, while HTML (HyperText Markup Language) is used to display data. In XML, you define your own tags based on the data, while in HTML, the tags are predefined and represent the structure of web pages. Additionally, XML is case-sensitive, whereas HTML is not. XML focuses on data, whereas HTML focuses on how the data is displayed.

DTD (Document Type Definition) and XML Schema are both used to define the structure of an XML document. However, XML Schema is more powerful as it supports data types, namespaces, and more complex structures. DTD is simpler but less expressive. XML Schema is written in XML itself, making it more extensible, while DTD has its own syntax. XML Schema also allows for richer validation rules compared to DTD. 

 DTD: <!ELEMENT note (to,from,heading,body)>
XML Schema: <xs:element name="note" type="xs:string" />

CDATA sections in XML are used to include text that should not be parsed by the XML parser. Any data enclosed within a CDATA section is treated as character data and not as markup. CDATA sections are particularly useful when embedding code snippets or special characters that might otherwise interfere with the XML parsing.

XPath is a language used to navigate through elements and attributes in an XML document. It provides a way to query XML data by defining paths to specific elements, attributes, and text. XPath is commonly used in conjunction with XSLT and XQuery to filter and select data from XML documents. It supports a wide range of functions for querying data. 

 XPath expression: /bookstore/book/title
This expression selects the 'title' element of every 'book' in the 'bookstore' element.

A well-formed XML document adheres to the basic syntax rules of XML. These include the following: 1. It must have a single root element. 2. All elements must be properly closed. 3. Tags must be properly nested. 4. Attribute values must be enclosed in quotes. 5. It is case-sensitive. A well-formed XML document can be parsed correctly by an XML parser.

An XML Schema defines the structure and rules for an XML document. It specifies what elements and attributes are allowed, their data types, and how they are related to each other. XML Schemas ensure that the XML document is valid and follows a predefined structure, which helps in data consistency across systems.
