Chapter 3: Working with Spry XML Data Sets A Spry XML Data Set is a JavaScript object that you can use to display data from an XML data source file on a web page. You can then use this data to create master and detail regions on the page that update as site visitors make different selections. About Spry XML Data Sets and dynamic regions Spry XML Data Set basic overview A Spry data set is fundamentally a JavaScript object. With a few snippets of code in your web page, you can create this object and load data from an XML source into the object when the user opens the page in a browser. The data set results in a flattened array of XML data that can be represented as a standard table containing rows and columns. For example, suppose you have an XML source file, cafetownsend.xml, that contains the following information: Summer Salad organic butter lettuce with apples, blood oranges, gorgonzola, and raspberry vinaigrette. 7 Thai Noodle Salad lightly sauteed in sesame oil with baby bok choi, portobello mushrooms, and scallions. 8 Grilled Pacific Salmon served with new potatoes, diced beets, Italian parlsey, and lemon zest. 16 Using XPath in your web page to indicate the data you’re interested in (in this example, the specials/menu_item node of the XML file), the data set flattens the XML data into an array of objects (rows) and properties (columns), represented by the following table. 91
@id item description price 1 Summer salad organic butter lettuce with apples, blood oranges, gorgonzola, and raspberry vinaigrette. 2 Thai Noodle Salad lightly sauteed in sesame oil with baby bok choi, portobello mushrooms, and scallions. 3 Grilled Pacific Salmon served with new potatoes, diced beets, Italian parlsey, and lemon zest. The data set contains a row for each menu item and the following columns: @id, item, description, and price. The columns represent the child nodes of the specials/menu_item node in the XML, plus any attributes contained in the menu_item tag, or in any of the child tags of the menu_item tag. The data set also contains a built-in data reference called ds_RowID (not shown) that can be useful later when you display your data. Additionally the data set includes other built-in data references, for example, ds_RecordCount, ds_CurrentRow, and others that you can use to manipulate the data display. YoucreateaSprydatasetobjectbyusingXPathintheSpry.Data.XMLDataSet constructor. The XPath defines the default structure of the data set. For example, if you use XPath to select a repeating XML node that includes three child nodes, the data set will have a row for each repeating node, and a column for each of the three child nodes. (If any of the repeating nodes or child nodes contain attributes, the data set also creates a column for each attribute.) If you do not specify an XPath, all of the data in the XML source will be included in the data set. After the data set is created, the data set object lets you easily display and manage the data. For example, you can create a simple table that displays the XML data, and then use simple methods and properties to reload, sort and filter, or page through data. The following example creates a Spry data set called dsSpecials, and loads data from an XML file called cafetownsend.xml: Spry Example var dsSpecials = new Spry.Data.XMLDataSet("data/cafetownsend.xml", "specials/menu_item"); . . . Note: The examples in this document are for reading purposes only and not intended for execution. For working samples, see the demos folder in the Spry folder on Adobe Labs. In the example, the first script tag links an open-source XPath library to the page where you’ll eventually display XML data. The XPath library allows for the specification of a more complex XPath when you create a data set: 7 8 16 SPRY User Guide 92
