Which of the following statements are true with reference to the way of describing XML data ? (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 Codes :
(a) and (c)
XML data is described either by a Document Type Definition (DTD), which lists the allowed elements and attributes, or by describing nodes (schema/description elements) inside the document structure.
XSL is a stylesheet language used to transform and display XML; it presents data but does not describe its structure.
So statements (a) and (c) describe XML data, while (b) does not.
Hence, (a) and (c).
