Question 1

The _____ attribute provides a way to uniquely identify a particular item in the source document.
A) title
B) unique
C) ID
D) object

Accepted Answer

The ID attribute is specifically designed to provide a unique identifier for an element in an HTML or XML document. This can be useful for a variety of purposes, including linking to specific sections of a long document or providing a reference for scripts and stylesheets. The other options (title, unique, object) do not serve this specific purpose.

Question 2

When two templates can be applied to the same node set, you distinguish them by adding the _____ attribute within the <xsl:template> tag.
A) mode
B) node
C) distinct
D) name

Accepted Answer

The mode attribute is used to distinguish between multiple templates that can be applied to the same node set. By adding a unique mode name to the mode attribute within the <xsl:template> tag, you can differentiate between the templates and control their application based on the mode.

Question 3

The syntax for declaring a required ID attribute is _____. A) B) C) D)

Accepted Answer

The correct syntax for declaring a required ID attribute in an XML DTD is `<!ATTLIST element attribute ID #REQUIRED>`, where `element` is the name of the element, `attribute` is the name of the attribute, `ID` specifies the type, and `#REQUIRED` indicates that the attribute is mandatory.

Question 4

In a step pattern, the _____ specifies the direction in which the processor should move through the node tree.
A) predicate
B) node test
C) axis
D) template

Accepted Answer

The axis in a step pattern specifies the direction in which the processor should move through the node tree. The other options (predicate, node test, template) are all important components in XPath, but do not specifically dictate the direction of traversal.

Question 5

To declare an ID attribute as optional in the source document's DTD, use the expression _____. A) B) C) D)

Accepted Answer

In a DTD, the correct way to declare an ID attribute as optional is to use #IMPLIED, which means the attribute is not required.

Question 6

-The accompanying figure shows a sample node set, with the context node shaded blue. In each image, the objects in the node set that are selected by a specific step pattern axis value are numbered and shaded in red. Which axis value is represented by image D?
A) descendant
B) child
C) following
D) following-sibling

Accepted Answer

The answer of 
-The accompanying figure shows a sample node...

Question 7

If you designate one node set as $n1 and the other as $n2 , the expression: generate-id($n1) = generate-id($n2) returns a value of _____ if the node set referenced by $n1 is the same as the node set referenced by $n2 .
A) false
B) union
C) true
D) implied

Accepted Answer

The generate-id() function returns a unique identifier for a node in the XML document. If two node sets have the same nodes, then the generate-id() function will return the same value for those nodes. Therefore, if generate-id($n1) = generate-id($n2) returns true, it means that $n1 and $n2 refer to the same set of nodes.

Question 8

-The accompanying figure shows a sample node set, with the context node shaded blue. In each image, the objects in the node set that are selected by a specific step pattern axis value are numbered and shaded in red. Which axis value is represented by image A?
A) ancestor-or-self
B) ancestor
C) preceding
D) preceding-sibling

Accepted Answer

The answer of 
-The accompanying figure shows a sample node...

Question 9

-The accompanying figure shows a sample node set, with the context node shaded blue. In each image, the objects in the node set that are selected by a specific step pattern axis value are numbered and shaded in red. Which axis value is represented by image G?
A) following
B) descendant
C) following-sibling
D) preceding-sibling

Accepted Answer

The "following-sibling" axis selects all the siblings after the context node, which matches the description of image G where the nodes immediately following the context node are shaded.

Question 10

In the generate-id() function, if you omit the node set argument, the function _____.
A) is applied to the current context node
B) is applied to the root node
C) is applied to all nodes
D) returns an error

Accepted Answer

If you omit the node set argument in the generate-id() function, then it is applied to the current context node.

Question 11

The XML processor creates a(n) _____ that matches each element to a specific ID.
A) index
B) library
C) path
D) attribute

Accepted Answer

The XML processor creates an index that matches each element to a specific ID.

Question 12

Once you generate the list of unique values, you can use the _____ element to write code to the result document for each unique value.
A) namespace
B) stylesheet
C) apply-templates
D) template

Accepted Answer

The apply-templates element is used to apply templates to specific nodes in an XML document. In this case, we would use it to apply a template to each unique value in the list.

Question 13

The general syntax of a step pattern is _____.
A) axis::predicate[node-test]
B) axis[node-test::predicate]
C) axis::node-test[predicate]
D) axis[predicate::node-test]

Accepted Answer

The general syntax of a step pattern is "axis::node-test[predicate]". This means that the step has three components: an axis, a node test, and an optional predicate. The axis specifies the direction of the step, the node test identifies the type of node to match, and the predicate filters the matching nodes based on some condition.

Question 14

ID attributes must be valid XML names and, therefore, they cannot contain _____ or begin with numbers.
A) spaces
B) underscores
C) capital letters
D) mixed case letters

Accepted Answer

ID attributes cannot contain spaces.

Question 15

The _____ function returns a node-set that matches a specified value from a key index.
A) index()
B) key()
C) return()
D) id()

Accepted Answer

The key() function is used to retrieve a node-set that matches a specified value from a key index. The index() function is used to retrieve a node-set based on an index, the return() function is used to return a result from a function, and the id() function is used to retrieve elements by their ID attribute value. Therefore, the key() function is the best choice for the given scenario.

Question 16

To generate an ID that identifies a specific node or node set within the source document, XPath provides the _____ function.
A) create-id()
B) set-id()
C) generate-id()
D) node-id()

Accepted Answer

The correct function to generate an ID that identifies a specific node or node set within the source document is the generate-id() function. The options A, B and D are not valid functions in XPath.

Question 17

-The accompanying figure shows a sample node set, with the context node shaded blue. In each image, the objects in the node set that are selected by a specific step pattern axis value are numbered and shaded in red. Which axis value is represented by image J?
A) preceding-sibling
B) preceding
C) ancestor
D) following-sibling

Accepted Answer

Image J represents the preceding-sibling axis value because it selects the node immediately preceding the context node in the document tree.

Question 18

In a step pattern, the _____ defines properties of the node to be matched.
A) node test
B) predicate
C) axis
D) template

Accepted Answer

The answer of In a step pattern, the _____ defines...

Question 19

The abbreviated form of the step pattern self::node() is _____.
A) .
B) ..
C) ../
D) /

Accepted Answer

The period (.) is the abbreviated form for the step pattern self::node(). It is used to refer to the current node or context node.

Question 20

-The accompanying figure shows a sample node set, with the context node shaded blue. In each image, the objects in the node set that are selected by a specific step pattern axis value are numbered and shaded in red. Which axis value is represented by image F?
A) following-sibling
B) descendant
C) ancestor
D) following

Accepted Answer

The "following" axis selects all nodes in the document that are after the context node, excluding descendants. Image F shows nodes that are after the context node, matching the "following" axis.
