Import XML Schema

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

Schema Type

Specifies the type to import XML schema: Import from XSD or Parse from an XML Instance.

Schema Name

Specifies the schema file by selecting the Browse button or inputting the URI string directly in the text box. In the URI string, you can reference parameters and constant level formulas in the current catalog data source and the special field User Name in the format "@fieldname".

RESTful
The button is activated when the specified URI string begins with http:// or https:// protocol. Selecting it opens the RESTful Data Source Options dialog, in which you can define the RESTful options for the schema data.

Starting Node

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

Instance

Specifies the XML instance by selecting the Browse button or input the URI string directly in the text box. It should match with the selected XSD schema. In the URI string, you can reference parameters and constant level formulas in the current catalog data source and the special field User Name in the format "@fieldname".

RESTful
The button is activated when the specified URI string begins with http:// or https:// protocol. Selecting it opens the RESTful Data Source Options dialog, in which you can define the RESTful options for the instance data.

Time Zone and Locale

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

The following options are available only when you select Import from XSD from the Schema Type drop-down list.

URI
Specifies to get instance data from URI.
User Defined
Specifies to get data from user defined interface.
- Class Name
  Specifies the full name (including package name) of the class by selecting the Browse button or inputting the class name directly in the text box. The class should be appended to the class path in the system environment.

  After filling in the Class Name field, the class name of the interface that the class implements will be displayed here.
- Parameter
  Specifies the parameter string for the user defined data interface. The parameter string must match the format defined in the class. In the parameter string, you can reference parameters and constant level formulas in the current catalog data source and the special field User Name in the format "@fieldname".
New Parameter
Opens the New Parameter dialog to create a parameter in the current catalog data source. You can then reference the parameter to dynamically specify a URI or user defined interface that matches with the selected XSD schema at runtime.
Validate with schema before fetching
If selected, Logi 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.
