Save time and money by using Codalogic LMX^™ to integrate XML data into your C++ applications.

Codalogic LMX^™ is a W3C XML Schema to C/C++ data binding tool, providing XML2C and XML2CPP / XML2C++ functionality.

It takes a W3C XML Schema definition and generates a set of C++ classes that represent the schema (see figure below). It also produces C++ code to automatically do the conversion of XML to C++ objects (called unmarshaling) and the reverse operation of converting the C++ objects to XML (called marshaling). This process is often called data binding.

Your code interfaces to the C++ objects generated by LMX, and needs no further knowledge of XML to perform the data binding.

Overview of XML C++ Data Binding Operation

To evaluate LMX you can download a trial version, download a basic binding example, or download a SOAP example.

The benefits of using LMX XML to C++ databinding include:

Quick project start-up
- Your project can consume fully fledged XML on day 1 facilitating early development iterations.
Easy to learn
- The output is regular C++ - No need to learn additional libraries and complex DOM / XPath syntax.
- Simple to build your project - A minimal number of source files are used so that you don't need to spend time managing builds and have less chance of build errors.
Easy coding
- No programming of tedious state code as required with SAX (and StAX) - LMX does all that in a couple of seconds (or less!) - Saves you doing boring programming tasks and avoids accidental cut and paste style errors.
- Generated documentation aimed at helping code development is included in the generated C++ .h file - Code development can be sped up by copying and pasting key constants and method names into your code.
- The View Prototypes mode in the Win32 GUI version allows drag-and-drop of method names and key constants directly into your code.
- Generates cross-linked HTML documenting your generated code - Further aids code writing.
Less time chasing bugs
- The names of variables are checked at compile time rather than run time - Simple typos in names are detected automatically and early - Less chance for latent bugs to be lurking in your deployed code. (Also allows operation with IntelliSense.)
- Resource management (such as memory) is taken care of - less chance for accidental memory leaks etc.
Cusomizable
- Add custom code and behaviors to the generated classes using Snippets and Snippet Event Handlers.
- The C++ data types representing the XML data types can be customized using C++ language syntax - No need to learn complex code generator configuration options, and less chance of introducing accidental differences between builds by using the wrong configuration - Use your own data types for more seamless integration with the rest of your code.
- Easy to switch between wide character strings and 'narrow' character strings - Choose your preferred way of handling characters - Particularly helpful if your character data is primarily ASCII (e.g. not primarily intended for human reading).
- Optional validation when your software writes to generated classes - allows you to trade off between testing in debug mode and performance in release mode by using a simple compiler switch.
Portable
- Available with source code to allow your product to run on different platforms. Even build and test on one platform and run on another.
- Binaries supplied for VC++ 6, VS 2003, VS 2005, VS 2008, GCC 3.2.3, GCC 3.4.6 and GCC 4.1.0.
- Customers have also used LMX on HP-UX, Apple, ARM, and X-Scale.
Cost effective
- Can save you weeks of coding effort.
- Royalty free run time - Distribute as many copies of your application as you like with no additional license fees.
Web services
- Easily build SOAP and REST based web services from XSD and WSDL files.
Strong customer base
- Customers include ABB Power Technologies, Alcatel-Lucent, Avaya, Boeing, General Dynamics, Hewlett Packard, Lehman Brothers, Lockheed Martin, QinetiQ, Samsung, Schlumberger, Seagate, Thomson (Grass Valley),...

In short, LMX is about saving you time writing code and effort debugging. As a result, LMX not only saves you money, but also allows you to improve your product by giving you more time to implement higher value, customer thrilling features.

LMX is available in a Microsoft Windows^® GUI version, a DOS command-line version and a Linux command-line version.

The Windows^® interface version makes it easy to generate C++ code. Simply select your XML schema file(s), the output file root for the C++ / HTML files, and press the compile button!
