❓ MCQ📘 CS311📑 Lec 13🏷️ 13.15. Handling Browser White-space DifferencesEasy🔁⭐💡📄🎓VU🏛️VU

When an XML document is edited using a simple text editor, it often contains line breaks, carriage returns, or space characters between element nodes. What are these characters called?

💻 xml Snippet

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.1. Introduction to XML DOM (Document Object Model)Medium🔁⭐💡🌟📄🎓VU🏛️VU

For which of the following application scenarios is a DOM-based parser highly recommended and preferred over a SAX-based parser?

A.When the XML document is exceptionally large and parsing memory is heavily constrained.
B.When you only need to process the XML document sequentially from top to bottom.
C.When you need to modify the XML document directly, or require random-access to elements in any order.
D.When you only need to perform high-speed data filtering on incoming streams.

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.16. Traversing and Navigating the Node TreeEasy🔁⭐💡📄🎓VU🏛️VU

In the XML DOM API, what is the term for accessing and traversing different nodes in the node tree by utilizing their hierarchical parent, child, or sibling relationships?

💻 javascript Snippet

y = x.firstChild;
while (y != null) {
    y = y.nextSibling;
}

A.Validating Nodes
B.Compiling Nodes
C.Navigating Nodes
D.Serializing Nodes

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.1. Introduction to XML DOM (Document Object Model)Easy🔁⭐💡📄🎓VU🏛️VU

Which parsing approach or model does the W3C DOM (Document Object Model) use to read and represent XML documents in application memory?

A.Event-based (streaming event tokens sequentially through callback interfaces)
B.Tree-based (constructing a complete hierarchical object tree of nodes in RAM)
C.DocumentHandler-based (incrementally mapping parsed text to file system pointers)
D.Rule-based (parsing and interpreting elements using compiled schema logic)

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.1. Introduction to XML DOM (Document Object Model)Easy🔁⭐💡📄🎓VU🏛️VU

True or False: The W3C Document Object Model (DOM) specification includes specialized sub-interfaces, and it can be used to dynamically access, update, and manipulate standard HTML documents.

💻 javascript Snippet

document.getElementById("demo").innerHTML = "Hello World!";

A.True
B.False

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.13. XML Node Properties (nodeName, nodeValue, nodeType)Easy🔁⭐💡📄🎓VU🏛️VU

Which property of the XML DOM Document object represents and returns the root node of the parsed XML document tree?

💻 javascript Snippet

var root = xmlDoc.documentElement;

A.rootNode
B.documentElement
C.firstChild
D.childNodes

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.15. Handling Browser White-space DifferencesMedium🔁⭐💡📄🎓VU🏛️VU

When parsing an XML document using standard W3C DOM specifications in modern web browsers, how are carriage returns, newlines, and spaces between elements (white-spaces) processed, and what issue does this raise?

💻 javascript Snippet

// Compliant browser counts child nodes including white-space text nodes:
var total = xmlDoc.documentElement.childNodes.length; // May return 9 instead of 4

A.They are completely ignored, posing no impact on the node list child count.
B.They are treated as empty Element nodes (nodeType 1), causing elements to replicate.
C.They are processed as Text nodes (nodeType 3), which alters the expected count of children in a node list.
D.They cause immediate validation failures and throw a ParserConfigurationException.

Q10

❓ MCQ📘 CS311📑 Lec 13🏷️ 13.3. Node Types and Child Node RulesMedium⭐💡📄🎓VU🏛️VU

A.DocumentType
B.DocumentFragment
C.EntityReference
D.Attr
