XBinder Overview

---

The XBinder code generation tool translates an XML Schema Definitions (XSD) or Web Services Definition Language (WSDL) source file into computer language C or C++ source files. These source files contain an application programming interface (API) that allows programatic data to be encoded to XML format and decoded to programatic variables. Each variable is of a type that corresponds to a type, element, or attribute defined within the XML schema document.

Each XSD or WSDL source file results in the generation of the following C/C++ language files:

• An include (.h) file containing C typedefs or C++ classes that represent each of the XSD types and global elements contained within the XSD source file, or the XSD types and WSDL operation input/output elements contained within the WSDL source file, and
• Multiple C/C++ source (.c/.cpp) files containing encode, decode, validation, and utility functions. One encode and decode function is generated for each XSD type. Utility functions may be generated for a given type or element to initialize, print, or generate test data.
• An optional makefile to build the generated code.

These files, when compiled and linked with the XBinder run-time encode/decode function library, provide a complete package for working with XML encoded data.

XBinder is compliant with the 2001 version of the W3C XML Schema standard (http://www.w3.org/2001/XMLSchema). The encode API functions generate valid, well-formed XML messages that are consistent with the encoding procedures described in the standard. The decode API options are capable of decoding an instance of an XML instance that complies with the schema definition.
