Question 2

Craig is working to develop an XSLT application to display election results, using XML files with the structures shown in the accompanying figure. He has heard that you have experience developing applications, and comes to you for guidance. -Now that the candidatesDoc variable has been created, Craig would like to define a key named cKey based on the values of the candidateID attribute for the candidate. Which of the following do you tell him shows the correct syntax to use to define this key? A) B) C) D)

Accepted Answer

The correct syntax to define a key in XSLT is . In this case, the key is named cKey, the element to match is candidate, and the attribute to use as the key is candidateID. Therefore, the correct syntax is .

Question 3

Sandra is working with an XML file containing product orders with the structure shown in the accompanying figure. She was just introduced to step patterns, and would like to incorporate them into the style sheet she is developing to display the orders data. She comes to you for help in developing expressions incorporating step patterns.
-Sandra would like to write an expression to show only those orders that have a preceding sibling containing the same orderDate . Which of the following do you tell her is the correct expression?
A) orderDate=preceding::order/orderDate
B) not(orderDate=preceding::order/orderDate)
C) orderDate=ancestor::order/orderDate
D) not(orderDate=ancestor::order/orderDate)

Accepted Answer

The correct expression for showing only those orders that have a preceding sibling containing the same orderDate is "orderDate=preceding::order/orderDate". This means that the value of the current orderDate is equal to a previous orderDate value in the same order element. The other expressions are incorrect because they either check for the orderDate value in the ancestor element (C and D) or negate the correct expression (B).

Question 7

Sandra is working with an XML file containing product orders with the structure shown in the accompanying figure. She was just introduced to step patterns, and would like to incorporate them into the style sheet she is developing to display the orders data.

-Sandra would like to write an abbreviated expression to select the parent of the current context node. Which of the following do you tell her is the correct abbreviated expression?
A) .
B) ..
C) ../
D) *

Accepted Answer

The ".." step pattern selects the parent of the current context node, and the abbreviated expression for this is just a single dot, so the correct choice is B. A selects the current context node, * selects all elements, and ../ selects the parent of the parent of the current context node.

D) orders::order/@items

Accepted Answer

Question 13

Craig is working to develop an XSLT application to display election results, using XML files with the structures shown in the accompanying figure. He has heard that you have experience developing applications, and comes to you for guidance.
-Now that the precinctNames key has been declared, Craig would like to use it to return a count of all votes from the precinct of Ceylon. Which of the following functions do you suggest he use to do this?
A) count(key="precinctNames" select="Ceylon")
B) count(key("precinctNames", "Ceylon") )
C) count::precinctNames//"Ceylon"
D) key("precinctNames", count("Ceylon") )

Accepted Answer

The correct function to use in this case is count(key("precinctNames", "Ceylon")). This function uses the key function to retrieve the node set of all votes from the precinct of Ceylon, and then counts them using the count function. Option A is incorrect because the count function does not take a "select" parameter. Option C is incorrect because it uses the count function in a wrong context and uses an incorrect syntax for the XPath expression. Option D is incorrect because it uses the count function in a wrong context and does not reference the correct node set.

Question 14

Sandra is working with an XML file containing product orders with the structure shown in the accompanying figure. She was just introduced to step patterns, and would like to incorporate them into the style sheet she is developing to display the orders data. She comes to you for help in developing expressions incorporating step patterns.
-Sandra would like to write an expression to select the third order element that follows the context node as a sibling. Which of the following do you tell her is the correct expression?
A) sibling::order[3]
B) following::order[3]
C) sibling-or-self::order[3]
D) following-sibling::order[3]

Accepted Answer

The correct expression to select the third order element that follows the context node as a sibling is "following-sibling::order[3]". The "following-sibling" axis selects all the siblings that come after the context node, and the "[3]" predicate selects the third occurrence of the "order" element among those siblings.

Question 15

Craig is working to develop an XSLT application to display election results, using XML files with the structures shown in the accompanying figure. He has heard that you have experience developing applications, and comes to you for guidance.
-Craig used the code you suggested to create the cKey key. However, he says he encountering problems when he tries to use this key to actually display data from the candidates.xml external file using the key. You explain to him that he will have to explicitly change the context node to the root element of the candidates.xml file first using a _____ element.
A) root
B) for-each
C) context
D) value-of

Accepted Answer

The "for-each" element is used to change the context node in XSLT, allowing you to iterate over nodes and set the context to each node in turn.

Question 16

Craig is working to develop an XSLT application to display election results, using XML files with the structures shown in the accompanying figure. He has heard that you have experience developing applications, and comes to you for guidance. -Craig would like to add a key named precinctNames based on each votes element's precinct name. Which of the following elements do you recommend he add to the style sheet to create the key with the correct syntax? A) B) C) D)

Accepted Answer

Craig is working to develop an XSLT...

Question 17

Sandra is working with an XML file containing product orders with the structure shown in the accompanying figure. She was just introduced to step patterns, and would like to incorporate them into the style sheet she is developing to display the orders data. She comes to you for help in developing expressions incorporating step patterns.
-Sandra would like to write an expression that moves up the node tree from the context node, selecting all of the elements that are order elements for the customer with the ID jbrown2738. Which of the following do you tell her is the correct expression?
A) ancestor::order[custID="jbrown2738"]
B) preceding::order[custID="jbrown2738"]
C) parent::order[custID="jbrown2738"]
D) descendant::order[custID="jbrown2738"]

Accepted Answer

The correct expression to move up the node tree from the context node and select all order elements for the customer with ID jbrown2738 is using the ancestor axis with the order element and specifying the custID attribute value to be "jbrown2738". Therefore, the correct expression is "ancestor::order[custID='jbrown2738']". The other options are not correct because they either move in the wrong direction (preceding), or do not specify the correct context node (parent, descendant).

Question 18

The _____ provides an expression that the node value should match.

Accepted Answer

The answer of The _____ provides an expression that the...

Question 19

Question 20

One useful tool for debugging a style sheet is the XSLT 1.0 _____ element.
A) watch
B) message
C) token
D) breakpoint

Accepted Answer

The XSLT 1.0 message element is the most useful tool for debugging a style sheet. It allows the developer to output information to the console or to a designated output file, giving insight into how the stylesheet is processing the input XML. While XSLT 2.0 and later versions have additional debugging tools such as a watch element and a breakpoint element, these do not exist in XSLT 1.0. The token element is not a valid XSLT element for any version, so choice C is incorrect.
