Question 1

Which of the following XPath expressions for relative paths refers to the parent of the parent of the context node?
A) ../parent
B) ..
C) .
D) ../..

Accepted Answer

The ../.. expression refers to the parent of the parent of the context node. The .. expression refers to the parent of the context node. The . expression refers to the context node itself. The ../parent expression refers to the parent element of the context node.

Question 2

The _____ attribute of the output element sets the URI for the public identifier in the <!DOCTYPE> declaration
A) doctype-public
B) encoding
C) version
D) doctype-system

Accepted Answer

The "doctype-public" attribute is used to set the URI for the public identifier in the <!DOCTYPE> declaration.

Question 3

In the sort instruction shown in the accompanying figure, the _____ attribute defines the language used to determine sort order.
A) lang
B) data-type
C) case-order
D) select

Accepted Answer

The lang attribute defines the language used to determine sort order. This is because different languages have different rules for sorting, such as whether to ignore case or sort numbers before letters. Therefore, specifying the language ensures that the sort order is appropriate for the language being used.

Question 4

New elements can be combined with predicates, conditional statements, and the _____ instruction to create a subset of the original source document in a new structure.
A) else-if
B) value-of
C) for-each
D) output

Accepted Answer

The for-each instruction loops through a specified set of elements in the input document and allows for the creation of a subset of the original document in a new structure. This, combined with predicates and conditional statements, can further refine the subset that is produced. The value-of instruction is used to output the value of a selected element or attribute, while the else-if instruction is used for conditional branching in XSLT. The output instruction is used to specify the format and destination of the transformed document.

Question 5

Attributes can also be included in a location path using the XPath expression: _____ @attribute .
A) node
B) match
C) path
D) uri

Accepted Answer

Attributes can be included in a location path using the XPath expression: node @attribute.

Question 6

A _____ node is the text contained within an element.
A) text
B) comment
C) content
D) string

Accepted Answer

The text node is the node that contains the text within an element. The other options, comment and string, refer to different types of data that can also exist within an XML document, but they are not the same as a text node. The option content is too broad and doesn't specifically refer to the text node within an element.

Question 7

The _____ attribute of the output element defines the output format.
A) encoding
B) version
C) doctype-system
D) method

Accepted Answer

The "method" attribute of the output element is used to define the output format, such as HTML, XML, JSON, etc. The other options (encoding, version, and doctype-system) are used to define the encoding type, version of the document, and system identifier of the DTD, respectively, but they do not define the output format.

Question 8

Multiple nodes sets can be combined into a single location path using the union ( _____ )  operator.
A) &
B) +
C) |
D) ^

Accepted Answer

The union operator in XPath is represented by the vertical bar symbol (|). It allows multiple node sets to be combined into a single location path. Therefore, the correct choice is C.

Question 9

The sort instruction can only be used within the _____ tag. A) B) C) Either a. or b. D) Neither a. nor b.

Accepted Answer

The instruction can be used within both and to sort the nodes being processed.

Question 10

The _____ element provides a condition to choose from.
A) xsl:otherwise
B) xsl:when
C) xsl:test
D) xsl:choose

Accepted Answer

The xsl:when element is used within xsl:choose to specify a condition to be evaluated. If the condition is true, the content of xsl:when is processed.

Question 11

The _____ element is applied when no conditions are satisfied.
A) xsl:otherwise
B) xsl:when
C) xsl:test
D) xsl:choose

Accepted Answer

The xsl:otherwise element is used as a default case when none of the xsl:when conditions are satisfied in the xsl:choose element.

Question 12

The _____ comparison operator combines two expressions, returning a value of true only if both expressions are true.
A) or
B) not
C) &=
D) and

Accepted Answer

The "and" comparison operator combines two expressions and only returns a value of true if both expressions are true.

Question 13

The _____ element chooses among different possible styles to apply to the result  document.
A) xsl:otherwise
B) xsl:when
C) xsl:test
D) xsl:choose

Accepted Answer

The xsl:choose element is used in XSLT to choose between multiple possible styles to apply to the output document. It contains a sequence of xsl:when elements, each with its own test expression, and an optional xsl:otherwise element for the default style.

Question 14

The _____ attribute tests whether the XPath expression returns a value of true or false; if it is true the enclosed style is applied.
A) when
B) test
C) choose
D) if

Accepted Answer

The test attribute is used in XPath expressions to test if a condition is true or false, and if it is true, the enclosed style will be applied. The other attributes listed (when, choose, if) are not relevant to this particular function.

Question 15

Which of the following XPath expressions for relative paths refers to the parent of the context node?
A) .
B) ..
C) //
D) ../..

Accepted Answer

The ".." notation in XPath is used to refer to the parent of the current node. Therefore, the answer is B, which represents "..".

Question 16

You can test for the presence or absence of an attribute or element by entering the attribute or element name without any _____ operator.
A) comparison
B) conditional
C) node
D) choose

Accepted Answer

You can test for the presence or absence of an attribute or element by entering the attribute or element name without any comparison operator.

Question 17

When writing a value to an XML attribute, you must enclose the XPath expression within _____.
A) curly braces
B) angle brackets
C) parentheses
D) double quotes

Accepted Answer

The answer of When writing a value to an XML...

Question 18

In the sort instruction shown in the accompanying figure, _____ is an XPath expression that returns a set of nodes.
A) data-type
B) case-order
C) node set
D) lang

Accepted Answer

The sort instruction in the figure is using an XPath expression to return a set of nodes to be sorted. Therefore, option C (node set) is the correct answer. Options A (data-type), B (case-order), and D (lang) are not relevant to the sorting process in this context.

Question 19

A(n) _____ is part of a location path that restricts the node set to only those nodes that fulfill a specified condition.
A) absolute path
B) predicate
C) attribute
D) template

Accepted Answer

Predicates are part of location paths in XPath that restrict the node set to only those nodes that fulfill a specified condition. This allows for more precise and targeted selection of nodes in an XML document. Absolute paths are used to specify the complete path to a node in the document, attributes are used to provide additional information about an element, and templates are used in XSLT for transforming XML documents.

Question 20

When using the sort instruction, if no attribute values are specified then the nodes are sorted in ascending order with _____ characters sorted first and the language determined by the operating system.
A) uppercase
B) lowercase
C) numeric
D) symbol

Accepted Answer

Uppercase characters are sorted first when no attribute values are specified, following the default collation order in many systems.
