Deck 6: Working With Xslt Functional Programming

Question 1

XSLT variables act more like constants because the value of an XSLT variable can only be defined once and it cannot be further updated.

Answer 1

True

Question 2

To operate recursively, a function must call itself employing the base case.

Answer 2

False

Question 3

If XPath is unable to calculate a value because of an error in the style sheet, it will return the text string "NaN" (Not a Number) .

Answer 3

True

Question 4

The XPath 1.0 numeric function ceiling ( number ) rounds number up to the next integer.

Question 5

The copy element creates a(n) deep copy of the active node.

Question 6

Variables are accessed using the reference @name where name is the variable name.

Question 7

Do not use the   entity to generate white space, even if you are generating HTML code, because that entity will not be recognized by the XSLT processor.

Question 8

The normalize-space() function can also be used to remove extraneous white space characters from the beginning or end of any text string.

Question 9

A(n) recursive template is a template that is not matched to a node set but instead acts like a function to display a calculated value or perform an operation.

Question 10

Named templates can be used to store variable values by having the last action of the template use the value-of element to set the variable value.

Question 11

If you place the include element at the beginning of your style sheet it will have precedence over the active style sheet.

Question 12

The copy-of element is similar to the copy element, as both create a deep copy of a node set.
