Tool that can combine many XSD files into one?

Question

I need to create XML serializer classes for approximately 65 XSD files, for which I am using Microsoft's XSD.EXE to generate the C# code...

However, I keep running into Window CMD's character limit in the resulting output file (in which XSD.EXE combines the name of every XSD included): "The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters."

To make a long story short, it seems that the only way I can get all these to validate and generate together is if I can merge all the XSDs (de-referencing the includes/imports, which XSD.EXE doesn't resolve the schemaLocation anyway) into one big one.

Please tell me that there exists a tool to do this...

Answer 1

I did locate a tool (basically an XSLT) for doing this kind of thing: Paul Kiel's XML Schema Flattener, but I haven't got my hands on it yet.

Other sources say that tools like Oxygen XML Editor and XMLSpy can do it too, but I can't figure out how.

In my case, I solved the problem via another circuitous route: shortening the name of each input XSD so that XSD.EXE's combined output name--which you can't choose--is below the 260 character limit.
