Answer Key

XML files: structure
Section A: Quick Questions
Q1
B — <name>Mia</name>
Q2
A — There is one root element that contains all the other elements
Q3
A — <student><name>Mia</name></student>
Q4
A — Named tags such as <mark>88</mark> label each value
Q5
B — <student id="7">Mia</student>
Section B: Match the Pairs
Q1
<student><name>Mia</name></student> → A student element with a child element name nested inside it, holding the data Mia
Q2
<student id="7"> → An opening tag with an attribute named id that has the value 7
Q3
Every element needs an opening tag and a matching closing tag with a forward slash → <name>Mia</name>
Q4
A well-formed XML file has one root element that contains all the other elements → <students><student><name>Mia</name></student></students>
Q5
<student><name>Mia</student></name> → The tags overlap. The name element must be closed before its parent student is closed, so the tags are not properly nested.
Q6
<student><name>Mia</name> → The student element is never closed, so the XML is not well-formed. It needs a closing </student> tag.
Section C: Definitions
Q1
<student><name>Mia</name></student> — XML stores data in nested, named elements. Each element has an opening and closing tag, and child elements sit inside a root element. The tags describe the data.
Section D: Fill in the Blanks
Q1
<name>Mia</name>
Q2
<students> <student>Mia</student> </students>
Q3
<student><name>Mia</name></student>
Q4
<student id="1"><name>Mia</name></student>
Q5
<student id="1"><name>Mia</name></student>
Section E: Spot the Error
Q1
B — The closing tag must match the opening tag exactly. It should be </student>, not </studen>.
Q2
C — The closing tag is missing its slash, so the name element is never closed. It should be </name>.
Q3
A — The root element's opening tag must match its closing tag </students>. It should be <students>.
Q4
C — Attribute values must be in quotes in well-formed XML. It should be id="7".
Q5
D — This line should close the student element with </student>. Without the slash it opens a new element instead.
