What is the correct syntax of the declaration which defines the XML version?
- A.
<?xml version="1.0" />
- B.
<?xml version="1.0"?>
- C.
<xml version="1.0" />
- D.
<xml version="1.0"?/>
- E.
<?xml version="1.0"?/>
Correct Answer
B. <?xml version="1.0"?>Explanation

All "Well-formed" XML documents are "Valid" XML documents.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false. While all "Valid" XML documents are "Well-formed" XML documents, the reverse is not true. "Well-formed" XML documents adhere to the basic syntax rules of XML, such as having a single root element and properly nested tags. However, "Valid" XML documents not only need to be "Well-formed," but they also need to conform to a specific Document Type Definition (DTD) or XML Schema. Therefore, a "Well-formed" XML document may not necessarily be "Valid" if it does not meet the additional validation rules specified by the DTD or XML Schema.Rate this question:

Which statement is true?
- A.
All XML elements must be lower case.
- B.
All XML documents must have a DTD.
- C.
All XML elements must be properly closed.
- D.
All of the above
- E.
None of the above
Correct Answer
C. All XML elements must be properly closed.Explanation
The correct answer is "All XML elements must be properly closed." This means that in an XML document, every opening tag must have a corresponding closing tag. This is a fundamental rule in XML syntax to ensure that the document is well-formed. The other statements in the question are not true. While it is common practice to write XML elements in lower case and to have a Document Type Definition (DTD) for validating the structure and data types in an XML document, they are not mandatory requirements.Rate this question:

Which statement is true?
- A.
XML tags are case sensitive
- B.

- C.

- D.
All of the above
- E.
None of the above
Correct Answer
D. All of the aboveExplanation
All of the statements mentioned in the options are true. XML tags are case sensitive, meaning that the opening and closing tags must have the same case. XML documents must have a root tag, which serves as the parent element for all other elements in the document. XML elements must be properly nested, meaning that each opening tag must have a corresponding closing tag and they cannot overlap. Therefore, the correct answer is "All of the above."Rate this question:

XML preserves white spaces.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
XML preserves white spaces because it treats them as significant data. Unlike HTML, which ignores extra white spaces, XML retains all white spaces including leading spaces, trailing spaces, and multiple consecutive spaces. This is important for maintaining the formatting and structure of the document, especially when it comes to preserving the integrity of textual data.Rate this question:

- A.
Yes
- B.
No
Correct Answer
B. NoExplanation
The given XML document is not "well formed" because there is an error in the opening tag of the "to" element. The attribute "age" is not properly formatted as it should be enclosed in double quotes. The correct format for the opening tag should be .Rate this question:

XML cannot contain Empty elements.
- A.
Yes
- B.
No
Correct Answer
B. NoExplanation
XML can indeed contain empty elements. In XML, empty elements are represented by self-closing tags, such as . These elements do not have any content or child elements. So, the answer "No" is correct as it contradicts the statement that XML cannot contain empty elements.Rate this question:

Which is not the correct name for an XML element?
- A.
<1dollar>
- B.
<Note>
- C.
<h1>
- D.
<First Name>
- E.
<xmldocument>
Correct Answer(s)
A. <1dollar>
D. <First Name>
E. <xmldocument>Explanation
The names <1dollar>, <First Name>, and <xmldocument> are not valid XML element names because they start with a number, contain a space, and contain an uppercase letter respectively. XML element names must start with a letter or underscore, and can only contain letters, numbers, underscores, hyphens, or periods. The names <Note> and <h1> are valid XML element names.Rate this question:

XML attribute values must always be enclosed in quotes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In XML, attribute values must always be enclosed in quotes. This is because quotes help to distinguish the attribute value from other parts of the XML document and ensure that the value is interpreted correctly. Without quotes, the XML parser may not be able to differentiate between the attribute value and other elements, leading to parsing errors. Therefore, it is necessary to enclose attribute values in quotes to adhere to the syntax and structure of XML.Rate this question:

Is this a "well formed" XML document? <?xml version="1.0"?> <to>Majnu</to> <from>Laila</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body>
- A.
No
- B.
Yes
Correct Answer
A. NoExplanation
The given XML document is not "well formed" because it is missing the closing tag for the root element. In a "well formed" XML document, every opening tag must have a corresponding closing tag. In this case, the closing tag for the root element is missing, making it invalid.Rate this question:

How does XML describe the data?
- A.
XML uses Document Type Definition to describe the data
- B.
XML uses XSL to describe the data
- C.
XML uses a description node to describe the data
- D.
XML uses Schema Definition to describe the data
- E.
All of the above
Correct Answer(s)
A. XML uses Document Type Definition to describe the data
D. XML uses Schema Definition to describe the dataExplanation
XML uses Document Type Definition (DTD) and Schema Definition to describe the data. DTD is a set of rules that defines the structure and elements of an XML document, while Schema Definition is an XML-based language that provides a more powerful and flexible way to describe the structure and constraints of an XML document. Both DTD and Schema Definition allow developers to define the allowable elements, attributes, and relationships within an XML document, ensuring data consistency and validity. Therefore, the correct answer is that XML uses both DTD and Schema Definition to describe the data.Rate this question:

Correct Answer
E. EXtensible Markup LanguageExplanation
XML stands for eXtensible Markup Language. XML is a markup language that is designed to store and transport data. It provides a flexible and self-describing format for representing structured information. XML allows users to define their own tags and document structure, making it extensible and adaptable to different applications and systems.

- A.
Yes
- B.
No
Correct Answer
B. NoExplanation
The given XML document is not well-formed because there are multiple issues with the tags. Firstly, the closing tag for the "to" element is incorrect, as it should be "". Secondly, the closing tag for the "from" element is placed incorrectly, as it should come after the closing tag for the "to" element. Lastly, there is an extra "Rate this question:

- D.
Xmln:[location]=“[prefix ]”
- E.
None of the above
Correct Answer
B. Xmlns:[prefix]=“[location]”Explanation
The correct answer is "xmlns:[prefix]=“[location]”". This syntax is used to define a namespace in XML. The "xmlns" keyword is followed by a colon and a prefix, which is then assigned a location or URI. This allows for the differentiation and organization of XML elements and attributes.Rate this question:

Which among the following is true about XML?
- A.
It is a single predefined markup language.
- B.
It has a fixed tag set.
- C.
It is a presentation language.
- D.
It is a metalanguage.
- E.
It has a predefined fixed tag set.
Correct Answer
D. It is a metalanguage.Explanation
XML stands for Extensible Markup Language. It is a metalanguage because it is used to define other markup languages. It provides a framework for defining customized markup languages for different applications. XML itself does not have a fixed tag set or a predefined markup language. It is not a presentation language either, as it is primarily used for data storage and exchange.Rate this question:
