Exam 7: Creating Element Groups

The general syntax of a step pattern is _____.

The _____ step to employ Muenchian grouping is to create a key for the element or attribute that you want to group using the key element.

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?

The first step in using extensions is to define an extension's namespace within the root element.

You can use the _____ function to create global variables that reference the root nodes of external documents.

-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?

Keys are declared in the _____.

To generate an ID that identifies a specific node or node set within the source document, XPath provides the _____ function.

The step pattern axis value _____ selects all nodes that appear before the context node in the source document, excluding the context node's own ancestors.

In a predicate, the expressions are resolved relative to the context node.

Provide an overview of the three key steps involved in employing Muenchian grouping.

Many XSLT processors support extension _____ that extend the data types associated with XSLT attributes.

The _____ step to employ Muenchian grouping is to add the following expression to the select attribute of a for-each or an apply-templates element: node set[generate-id() =generate-id(key(name,expression) [1]) ] .

In addition to extension functions, you can also use extension elements and _____ in your style sheets.

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?

The _____ is an index based on a node specified in the match attribute using the values from a node specified in the use attribute.

One useful tool for debugging a style sheet is the XSLT 1.0 _____ element.

The syntax for declaring a required ID attribute is _____.

The key() function cannot be used with data from external documents.
