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.

csp-10-2-2: 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.

csp-10-2-3: Which function searches through the XML tree and retrieves the element that matches the specified tag.

Python lists and dictionaries

False
Try again!

csp-10-2-7: 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.

csp-10-2-8: Which format is constructed by nesting dictionaries and lists as needed.

csp-10-2-9: Which of the following are used for security surrounding API usage?
