ITPEC IP April 2018 Question 9

Topic: Algorithm and ProgrammingAlso asked in October 2022

Which of the following is the method for describing the logical structure of a sentence in XML?

a)Enclosing the sentence, clauses, and other elements by using double quotes (“”)b)Separating the sentence, clauses, and other elements by using commasc)Enclosing the sentence, clauses, and other elements by using tagsd)Separating the sentence, clauses, and other elements by using tabs

Explanation

Enclosing the elements with tags — XML marks each element with a start tag and an end tag, and nesting the tags shows the structure.

For a sentence, a tag pair such as <sentence> … </sentence> encloses the whole sentence, and tag pairs for its clauses sit inside it. The nesting forms a tree, so the logical structure can be read by programs. In XML the tag names are chosen by the user to describe what the data means.

Answer (c)

Why not others:

•(a) — double quotes enclose attribute values in XML; they do not mark the elements of a structure
•(b) — commas separate values in flat formats such as CSV, which cannot express nesting
•(d) — tabs separate fields in tab-delimited text; in XML they are only whitespace

Key rule: XML describes structure with user-defined tags nested inside each other; CSV and tab-delimited files hold flat rows of values only.
