Section 15.9 Multiple Choice Questions

Activity 15.9.1.

An XML document can be depicted using what kind of structure?
  • Paragraph
  • Paragraph structure is a writing style, not a coding outline.
  • Tree
  • An XML document can be depicted as a tree structure where there is a top element, and other tags are drawn as children of their parent elements.
  • Stem and Leaf
  • Stem and Leaf is a plot used to display quantitative data, where each data value is split into a "leaf" (usually the last digit) and a "stem" (the other digits).
  • Nested
  • While the structure of XML is inherently nested, it follows a tree structure.

Activity 15.9.2.

What language is XML most similar to?
  • CSS
  • CSS is a language that describes the style of an HTML document.
  • Python
  • Python is a programming language, but is quite different than XML.
  • JavaScript
  • JavaScript is the programming language of HTML and the Web. It looks pretty different from XML.
  • HTML
  • HTML is the standard markup language for Web pages. It is very similar to XML, though XML is more structured.

Activity 15.9.3.

Which function searches through the XML tree and retrieves the element that matches the specified tag.
  • find
  • The find function searches through the XML tree, retrieving the element that matches the tag.
  • findtag
  • This is not a real function.
  • match
  • match is an attribute that can be used to associate a template with an XML element.

  • True
  • Try again!

Activity 15.9.5.

The JSON format is most similar to which of the following?
  • JavaScript arrays
  • The JSON format was inspired by the object and array format used in the JavaScript language, but was influenced and looks nearly identical to Python lists and dictionaries.
  • JavaScript
  • JSON is text, written with JavaScript object notation, but the format is nearly identical to one of the other options.
  • XML nodes
  • JSON and XML are used for similar purposes, but JSON is written with simpler structures.
  • Python lists and dictionaries
  • Python’s syntax for dictionaries and lists influenced the syntax of JSON. So the format of JSON is nearly identical to a combination of Python lists and dictionaries

Activity 15.9.6.

True or False? JSON maps directly to dictionaries and lists.
  • True
  • JSON is a very natural format to use, as it maps directly to some combination of dictionaries and lists.
  • False
  • Try again!

Activity 15.9.7.

There is an industry trend away from _______.
  • XML
  • JSON is simpler and more directly maps to native data structures we already have in programming languages, the parsing and data extraction code is usually simpler and more direct when using JSON.
  • JSON
  • XML is more self descriptive than JSON, but does not have the simpler and more direct mapping that JSON has.

Activity 15.9.8.

Which format is constructed by nesting dictionaries and lists as needed.
