This is a converter which takes blogML (https://code.google.com/p/blogml/) generated by Dotnet blog engine (http://dotnetblogengine.net/) and converts into markdown, as required by Docpad (http://docpad.org). I've written it in NodeJS for exporting my blog, which is based on BlogEngine.NET 1.6.1.0. I haven't tested it for latest versions of BlogML (Anyways, it is just a matter of changing a few lines in this code).
