Question: The advantages of XML over HTML are (i) It allows processing of data stored in web-pages (ii) It uses meaningful tags which aids in understanding the nature of a document (iii) Is simpler than HTML (iv)It separates presentation and structure of document

Answer:

The following statements are true for the advantages of XML over HTML:

(i) It allows processing of data stored in web-pages: XML provides a structured and extensible format for storing and transmitting data. Unlike HTML, which is primarily focused on defining the presentation of web pages, XML allows the inclusion of data within the document. This data can be processed, extracted, and used by applications, making XML suitable for data exchange and integration.

(ii) It uses meaningful tags which aids in understanding the nature of a document: XML allows the use of user-defined tags, which can be chosen to reflect the semantics and meaning of the data being represented. This makes XML more expressive and facilitates better understanding of the nature of the document and its content.

(iv) It separates presentation and structure of the document: XML is primarily concerned with defining the structure and content of the document, separating it from the presentation or formatting. This separation allows for greater flexibility in how the data is presented and styled, as the presentation can be defined separately using technologies like CSS (Cascading Style Sheets) or XSLT (Extensible Stylesheet Language Transformations).

To clarify, the statement (iii) "XML is simpler than HTML" is not entirely accurate. XML and HTML serve different purposes, and their complexity can vary depending on the context and specific requirements. XML is more flexible and extensible, which can make it appear more complex compared to the specific and predefined nature of HTML.
