2 From Altova

Check out these 2 relatively inexpensive but very useful tools from Altova:

MapForce, a visual (and command-line) environment for file conversion. You can map input records (XML, CSV, EDI, OOXML and WSDL definitions, among others) to new layouts and indicate what transformations need to be performed as the fields are resequenced into the new data formats. The visual interface allows you to drag and drop transformations from a bundled library and test the output in a sandbox environment that supports output validation. And to avoid relying on XSLT transformations done quasi-interpretively, MapForce generates code in C++, C# and Java that can use standard libraries such as MSXML or Xerces and integrate with leading IDEs. MapForce starts at $299 and runs to $1,200, depending on the feature set.

UModel which supports all 13 UML 2.1 diagrams plus Business Process Modeling Notation. It enables code generation in Java, C# and Visual Basic, with full support for bidirectional (diagram to code, code to diagram) synchronization. It can export the diagrams in EMF and .png formats, and generate basic documentation using them. Pricing is similar to that for MapForce.
