Release 10.1A: OpenEdge Getting Started:
WebSpeed Essentials

XML

Extensible Markup Language (XML) is supported directly in WebSpeed’s SpeedScript (4GL) language, allowing you to exchange data between OpenEdge-supported data sources and XML documents. XML, considered the standard for exchanging data between disparate applications, is a markup language like HTML. However, unlike HTML, XML describes document content in terms of the data without regard for how it is to be displayed.

WebSpeed contains an industry standard XML parser, allowing developers to use SpeedScript to create programs that send and receive XML documents to/from other XML-enabled Web applications using Document Object Model (DOM) and SAX interfaces.
