Developing with XML in OpenEdge 1–12
Reading and Writing XML with the Document Object Model (DOM) 2 ABL supports two XML programming interfaces: the Document Object Model (DOM) and the Simple API for XML (SAX). This chapter provides a quick overview of key XML terminology and then covers the DOM interface, as described in the following sections: • XML terminology • The ABL DOM interface • Creating XML output from ABL • Reading XML input into ABL • Internationalization • Error handling • Validation In addition to basic XML knowledge, the minimum requirement for working with XML in ABL is a familiarity with using and manipulating ABL objects and a knowledge of network communication by way of either the Web or sockets.
