The Internal XML Component

The Rules Engine enables you to export data in XML format from application tables and to import XML documents into your application tables. To achieve this you can use the internal XML component. This component provides methods to:

·	Export data in simple XML Format (XML.Export).

·	Export data in more complex XML Format (XML.SQLExport).

·	Import XML data into an application table.

·	Create Document Type Definition documents (DTD's) for tables.

·	Send queries in XML format to the Rules Engine.

·	Convert SQL syntax to XML format.

These methods of the XML component can be called from INVOKE statements. INVOKE can for example be used in constraints, in the SQL Command Dialog, or through the USoft Remote Rules Service API.

This section describes the XML component and its methods. Also, examples are provided, to show how the XML component can be used.
