Term
In designating an element in an XML structure, if you wanted to refer to one of the sub elements, you will have to create a string of child elements from the root to the desired child element.
 Definition
True
Term
Xpath expressions can be created using _________ paths, so that instead of starting at the root element, you can simply reference the element from within the path structure and go from there.
 Definition

Term
To construct a relative path expression to select every count element, what would the correct expression look like?
 Definition
count
Term
If you wanted to select every cost element that had a book parent, you would use a relative expression like this:
 Definition
book/cost
Term
With XPath expressions, _______ are used to select the descendants of an element.
 Definition
//       (double forward slashes)

 Definition
..             (2 periods)

Besides testing the values of elements, you can also use predicates to check the values of attributes.
 Definition
True
Term
The format for writing an attribute-related predicate is:
 Definition
element[@element's attribute some test here]
Term
Whenever you need to select an element and use a predicate on that same element, you will need to use a ______ to access that element's value.
