Release 10.1A: OpenEdge Development:
Programming Interfaces

Use cases

The XML read and write features are robust and versatile. The examples described below demonstrate common problems that can be solved with the features:

Provide interoperability between OpenEdge and another XML-enabled platform or application. For example, Crystal Reports can accept XML data and XML Schema when building and displaying reports.
Use XML data and XML Schema as a persistent storage mechanism between 4GL sessions.
Provide XML Schema from the 4GL for use in third-party tools. For example, Microsoft Visual Studio .NET has a utility that creates an ADO.NET dataset from an .xsd file. By writing a ProDataSet definition to an .xsd file, you can then use the Microsoft utility to quickly model a ProDataSet as an ADO.NET DataSet class.
You may have existing 4GL code that performs XML reads and writes with the DOM or SAX interface that you can simplify and replace with the temp-table and ProDataSet object XML read and write features.
