l Choose the element from the XML Schema or DTD you want to use as the root element
l Associate the XML Schema or DTD with an XML instance
This section describes how to perform these procedures. Choosing a Root ElementWhen you add an XML Schema or a DTD to the data sources panel, Stylus Studio displays the Choose Root Element dialog box, shown in Figure 512. The Choose root element drop-down list displays all the child elements of the XML Schema or DTD document you selected as a data souce. Select the element you want to use as the document root and click OK. Associating an XML Instance with the SchemaBefore you can preview or generate code for an XML Publisher report, you need to associate an XML document, referred to as an XML instance, with any XML Schema or DTD documents you are using as source documents. When you click the Preview or Generate buttons on the XML Publisher toolbar, if you have not already associated an XML instance with the schema you are using as data sources, Stylus Studio displays the Associate with XML Instance dialog box, shown in Figure 512. Each entry in the Schema field represents an XML Schema or DTD document used as a data source. To associate it with an XML instance:
1. Click the XML Instance field.
Stylus Studio displays the Open dialog box.
2. Choose the XML document you want to use as the XML instance and click the Open button.
The Open dialog box closes; the URL for the file you selected appears in the XML Instance field.
3. Click OK.
Stylus Studio previews the XML Publisher report, or begins the code generation process.
