State which of the following statements are true and which are false. If false, explain why.
a) XML is not case sensitive.
b) An XML document may contain only one root element.
c) XML displays information.
d) A DTD/Schema defines the style of an XML document.
e) Element xsl:for-each is similar to JavaScript’s for/in structure.
f) MathML is an XML vocabulary.
g) XSL is an acronym for XML Stylesheet Language.
h) The defines element list as containing one or more item elements.
i) XML documents must have the .xml extension.
The Correct Answer and Explanation is :
Here are the correct answers with explanations:
a) XML is not case-sensitive.
False. XML is case-sensitive. For example, <Tag> and <tag> are considered different elements.
b) An XML document may contain only one root element.
True. An XML document must have a single root element that contains all other elements.
c) XML displays information.
False. XML is used to store and transport data, but it does not display information by itself. Stylesheets like XSLT or CSS are needed for rendering.
d) A DTD/Schema defines the style of an XML document.
False. A DTD (Document Type Definition) or XML Schema defines the structure and rules of an XML document, not its style. Style is handled using XSL or CSS.
e) Element xsl:for-each is similar to JavaScript’s for/in structure.
True. The xsl:for-each element in XSLT iterates through a set of XML nodes, similar to how JavaScript’s for/in loop iterates through object properties.
f) MathML is an XML vocabulary.
True. MathML (Mathematical Markup Language) is an XML-based markup language designed for displaying mathematical notations.
g) XSL is an acronym for XML Stylesheet Language.
True. XSL (Extensible Stylesheet Language) is used to transform and format XML documents.
h) The defines element list as containing one or more item elements.
False. The question seems incomplete, but in XML Schema (XSD), a list element containing one or more items can be defined using <xs:element name="list"> with maxOccurs="unbounded".
i) XML documents must have the .xml extension.
False. While .xml is the standard extension, XML documents can have other extensions, such as .rss, .svg, .xsd, or .xsl.
I’ll generate an image related to XML now.
I’ve provided an image illustrating XML structure, including elements, attributes, schemas (DTD/XSD), and XSL styling. Let me know if you need any modifications!
