Checking for Cycles in a Graph
This example provides a generic procedure to look for cycles in a graph, and then applies this procedure to a data file to see if the ID/IDREF links are cyclic. It illustrates the use of
251
Generating an Attribute Conditionally
This example shows the use of
263
Deciding the Attribute Name at Runtime
This example shows the use of
264
Using an Attribute Set for Numbering
This stylesheet shows an unusual way of using attribute sets, to illustrate that the attributes generated by an attribute set do not need to have fixed values.
270
Using Recursion to Process a Sequence of Nodes
This example illustrates how to use a recursive named template to process a sequence of nodes. It uses this technique to find the longest speech in a play.
275
Using Recursion to Process a Sequence of Strings
This example uses a recursive named template to process a sequence of strings, obtained by splitting a line of text into its constituent words. It uses this technique to find phrases of the form “A and B”, where A and B are both the names of characters in a play.

Converting Attributes to Child Elements
This example illustrates how

Showing the Ancestors of a Node
This example stylesheet can be applied to any XML document. For each element it processes all its ancestor elements, in reverse document order (that is, starting with the parent node and ending with the document element), and outputs their names to a comment that shows the position of the current node.

Single-Level Grouping by Value
This stylesheet uses
331
Multilevel Grouping by Value
This example groups employees by department, and groups the departments by location.
333
Grouping Consecutive Elements by Name
This example shows how the group-adjacent attribute of
336
Handling Repeating Groups of Adjacent Elements
This takes the previous example and makes the problem more difficult, by removing another layer of markup from the source document, so that it is necessary to infer multiple levels of hierarchic structure from the pattern of leaf elements in the tree.
338
Handling Flat XHTML Documents
This example shows how to use the group-starting-with attribute of
elements that are logically subordinate to the
340
Calculating Annual Leave
This is a simple illustration of the use of stylesheet functions to structure a computation in a stylesheet. It uses two user-defined functions, a function to calculate the annual leave entitlement of an employee, which in turn calls a function to calculate the employee's length of service given a starting and ending date.

Looking for Cycles Among Attribute Sets
This example illustrates the use of recursive stylesheet functions to analyze a graph structure. Specifically, it analyzes an XSLT stylesheet as its source document, to determine whether there are any cyclic dependencies among the attribute set definitions in the
