Lists

A list is visual component that iterates over the data it contains and contains one or more items. You typically create a list when you want your report to display a list of dynamic values - all the books, by title, in the books.xml document, for example.

Lists are formatted using bullets, but you can choose numeric, alphabetic, and other symbols like squares and circles. Depending on your needs, you might prefer to use the repeater or table components for dynamic data. See Repeaters and Tables for more information.

Creating a List

The easiest way to create a list in XML Publisher is to drag and drop a repeating element. When you drop the repeating element on the canvas, Stylus Studio displays a short-cut menu with an Insert List choice. The list's context and XPath are set based on the repeating element used to create it. You specify the data you want the list to contain by dragging the appropriate node from the data sources panel and dropping it in the list as Value.

You can also create a list manually (Report > Insert > List, or select Insert List from the canvas short-cut menu). When you create a list like this, however, the context and XPath are not set for you, and it will iterate over the data you specify only if you also define the Loop context and Xpath properties for an item.

Graphical Representation

As shown in Figure 537, a list is represented as a bounding box drawn with a dashed line containing a bullet symbol and, usually, a loop symbol ( ). If you created the list manually, the loop symbol appears only if you specify the Loop property's Context and XPath sub-properties for an item.

Sorting

By default, data for dynamic lists is displayed in document order. You can use an XPath expression in the Loop property's Sort sub-property to specify a different sort order.
