Write down Syntax rules for XML declaration.

Write any three characters which are reserved by XML along with corresponding character description and replacement entity.

What is RSS? Why and who should use RSS?

What is JSP and why do we need it?

Design the following webpages using JSP. Note: you can use HTML to design the form of the first page. a sample:

XML (eXtensible Markup Language) is a flexible text format used for the creation of structured documents and data on the web. The XML declaration is an optional statement typically placed at the beginning of an XML document, specifying version, encoding, and standalone status. The syntax rules for XML declaration include:

  • It must appear at the very top of the document, before any other content.
  • It begins with <?xml and ends with ?>.
  • The declaration can include attributes such as version, encoding, and standalone, for example: <?xml version="1.0" encoding="UTF-8" standalone="yes"?>.
  • The version attribute is mandatory if the declaration is present, specifying the XML version, such as "1.0".
  • The encoding attribute specifies the character encoding used, with "UTF-8" being most common.
  • The standalone attribute indicates whether the document relies on external definitions, with values "yes" or "no".

In XML, certain characters are reserved because they have specific syntactic meanings, such as delimiters or operators. Three such characters are:

  1. & (ampersand): Represents the start of an entity reference. Replacement entity: &amp;.
  2. < (less than): Used to open a tag. Replacement entity: &lt;.
  3. > (greater than): Used to close a tag. Replacement entity: &gt;.

RSS (Really Simple Syndication) is a type of web feed that allows users and applications to access updates to online content in a standardized, computer-readable format. It is primarily used for syndicating news headlines, blog posts, or other frequently updated web content. Users should utilize RSS feeds to stay informed about updates without visiting multiple websites. Content providers and publishers benefit from RSS because it helps distribute their content widely and efficiently, reaching a broader audience through feed aggregators or readers.

JSP (JavaServer Pages) is a server-side programming technology used to create dynamic web content. It allows developers to embed Java code directly into HTML pages, enabling the creation of platform-independent, dynamic web applications. JSP simplifies the development process by separating presentation from business logic and allows for easier maintenance and scalability. We need JSP because static HTML pages cannot handle dynamic data or user interactions, so server-side scripting is essential for building interactive, data-driven web applications.

Designing webpages using JSP involves creating HTML forms and embedding Java code for server-side processing. For instance, a simple login form can be made using HTML, which submits data to a JSP page that processes user input, accesses databases, or performs business logic before rendering a response. This integration facilitates interactive web applications, personalized content, and real-time data updates, making JSP a vital tool for modern web development.
