Questions and Answers
  • 1. 

    XML: Content between elements may carry special characters

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    The statement is correct because in XML, content between elements can indeed carry special characters. XML allows the use of special characters such as angle brackets (< and >), ampersands (&), quotation marks ("), and apostrophes ('), among others. However, these special characters need to be properly encoded using entities to avoid any parsing errors or conflicts with the XML structure.

    XML: Attributes may carry no value

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    XML allows attributes to be specified without a value. This means that an attribute can be present in an XML element without having any assigned value. This can be useful in certain situations where the presence of an attribute itself is significant, rather than its value. It provides flexibility in XML document design and allows for more concise representation of data.

    XML: Closing tags need to carry a slash on an arbitrary position,eg "" or "".

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    The statement is incorrect. In XML, closing tags always carry a slash before the tag name, at the very beginning of the closing tag. Therefore, the correct answer is "yes".

    Rate this question:

  • 4. 

    XML: Each document starts with ""

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    The given answer "no" is correct because the XML document starts with the opening tag "". The options "yes" and "no" indicate whether the statement is true or false, and in this case, the statement is false.

    Rate this question:

  • 5. 

    Each document belongs to a maximum of one namespaces.

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    This statement is incorrect. In many programming languages and systems, a document can belong to multiple namespaces. Namespaces are used to organize and group related elements or entities within a system, and a document can be associated with one or more namespaces depending on its purpose and context. Therefore, the correct answer is "no".

    Rate this question:

  • 6. 

    The attribute "xml:lang" defines the used encoding.

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    The attribute "xml:lang" is used to define the language of the content in an XML document, not the encoding. The encoding of an XML document is typically specified in the XML declaration using the "encoding" attribute. Therefore, the statement that "xml:lang" defines the used encoding is incorrect.

    Rate this question:

  • 7. 

    Cascading stylesheets are well-formed xml documents.

    • A.

      Yes

    • B.

      No

    Correct Answer
    B. No
    Explanation
    Cascading Style Sheets (CSS) are not well-formed XML documents. CSS is a separate language used for styling HTML documents, and it has its own syntax and structure. While CSS can be written in XML syntax using the CSS XML format, it is not a requirement and most commonly, CSS is written in a different syntax. Therefore, the statement that CSS is well-formed XML documents is incorrect.

    Explanation
    DTD stands for Document Type Definition. A DTD is a set of rules that defines the structure and elements of an XML document. It specifies the allowed elements, attributes, and their relationships, as well as any constraints or restrictions on their usage. The purpose of a DTD is to ensure that XML documents adhere to a specific format or schema, making it easier to validate and process the data contained within them.

    Rate this question:

  • 17. 

    Which statement is true?

    • A.

      All XML documents must have a DTD.

    • B.

      All XML elements must be lower case.

    • C.

      All XML elements must be properly closed.

    • D.

      All 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 XML, every element must have a closing tag, even if it is an empty element. 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 recommended to have a Document Type Definition (DTD) for XML documents, it is not mandatory. Similarly, XML elements can be written in either lower case or upper case, as XML is case-sensitive.
