Question 27 |

(a)XML uses DTD to describe the data
(b)XML uses XSL to describe the data
(c)XML uses a description node to describe the data
(a) only | |
(b) only | |
(a) and (b) | |
(a) and (c) |
Question 27 Explanation:
Option(A): XML uses DTD to define the structure of an XML document. It defines the structure with a list of legal elements. Hence statement (a) is correct.
Option(B): XSLT (eXtensible Stylesheet Language Transformations) is the recommended style sheet language for XML.XSLT is far more sophisticated than CSS. With XSLT you can add/remove elements and attributes to or from the output file. You can also rearrange and sort elements, perform tests and make decisions about which elements to hide and display, and a lot more. XSLT uses XPath to find information in an XML document.
Hence here XML is not using XSL to describe the data. So statement (b) is wrong.
Option(C): Everything in an XML document is a node:
The entire document is a document node
Every XML element is an element node
The text in the XML elements are text nodes
Every attribute is an attribute node
Comments are comment nodes
Hence statement (c) is correct.
