## XML Connection Wizard

This wizard appears when you select XML and click OK in the New Data Source dialog, or in the Catalog Browser right-click a data source and select Add XML Connection from the shortcut menu or right-click an existing XML connection and select Edit Connection from the shortcut menu. It helps you to import an XML schema and transform it to a relational schema for future use, and consists of the following screens:

- Import XML Schema screen
- Modify Schema Properties screen
- Transform XML Schema screen
- Transformed Relational Schema screen
- Add Table screen

Back

Goes back to the previous screen.

Next

Goes to the next screen.

Finish

Finishes confirming to transform an XML schema to a relational schema.

Cancel

Does not retain changes and closes this wizard.

Help

Displays the help document about this feature.

### Import XML Schema screen

Specifies the necessary information to import XML schema. See the screen.

Schema Type

Specifies the type to import XML schema. You can import from XSD or parse from an XML instance.

Schema Name

Specifies the schema file by clicking the Browse button or inputting the URI string directly in the text box.

Starting Node

Specifies the starting node, according to the root name in the XML source.

Notes:

- If a value of DateTime data type is accurate to millisecond, a message - Invalid Value will still pop-up although the value is valid according to the W3C standard. If that, ignore the error message and continue the transformation steps.
- If you select to create a parameter and then dynamically specify an XML instance at runtime, the XML instance will be validated at runtime rather than in the importing process.

Instance

Specifies the XML instance. It should match with the selected XSD schema.

These two operations below are available only when you select Import from XSD from the Schema Type drop-down list.

- URI
  If selected, specify an XML file for the XSD by clicking the Browse button or input the URI string directly in the text box.
- Parameter
  If selected, click to open the Create Parameter dialog to create a parameter and then dynamically specify an XML instance that matches with the selected XSD schema at runtime.

Validate with schema before fetching

If selected, JReport Designer will validate whether or not values in the XML instance is valid according to the W3C standard and the specified XSD schema. If not, a message - Invalid Value will pop up.

Time Zone and Locale

Opens the Time Zone and Locale Options dialog to specify the default time zone and locale for the XML instance.

Refresh

Available only when you edit an existing XML connection. Once you make some change in the wizard and click the Refresh button, the XML schema information will be reloaded according to what you have changed.

### Modify Schema Properties screen

Specifies properties of the XML schema. See the screen.

Schema

Lists the corresponding schema structure of the root. stands for elements, stands for the attributes in the XML schema and stands for the references of elements.

Properties

Lists all the properties of the selected elements and attributes in the schema.

- Name
  Displays names of properties of the selected elements or attributes.
- Value
  Specifies values of properties for the selected elements or attributes.

Note: When the property Data Type is specified as Date, Time or DateTime, you can specify the Format Pattern for them to make values of the data type displayed in the required format. For details about these properties, see the section Supplementing information for the XML schema.

### Transform XML Schema screen

This screen allows you to specify an XPath as a transforming start point. All the elements matching with the selected XPath and their attributes will be transformed to the relational schema. See the screen.

### Transformed Relational Schema screen

This screen lists the transformed relational schema structure. It helps you to click Next to confirm the transformation results and go into the Add Table screen. See the screen.

### Add Table screen

Adds tables that are transformed from the relational schema to the connection. This screen is not available when you edit an existing XML connection. See the screen.

Schema

Lists the schemas in the database for you to select.

Tables

Lists the tables transformed from the XML schema.

Added Tables

Lists the tables that you have added from the relational schema.
