XML Interface was introduced by Lycia 3 for the convenience of the data processing. Any configuration files used to be stored in the plain text format which made them difficult to use and often led to bugs in the programs using them due to a large amount of code needed to process a single value. With the introduction of an XML parser integrated into the 4GL code the configuration files can be stored in the XML format and thus utilized in a simpler and cleaner way.
Lycia XML Interface allows XML documents to be created, loaded and manipulated directly from within 4GL programs. This creates a vast range of possibilities for customizing and localizing your programs.
