static site generators

[Lucas Vogel <lucas.vogel@endpointsystems.com>]

One thing I've noticed a big uptick in lately are static site generators, where you use a CLI app to create a site template and you use the tool features (typically the language features the CLI was written in) to put the site elements (themes, templates, content, etc.) together, and then use the tool to compile, deploy and host the site itself. You can find a list of them by popularity rankings here: https://www.staticgen.com/ If you look at the site generators, you see them written in Javascript, Go, .NET, PHP, Python; even bash and awk have a couple. But only one (Stog) have anything to do with XML. 

Does anyone know of any static site generators written around the XML format? I know of one on the .NET side for product documentation (Sandcastle) but it's increasingly becoming an obsolete framework (mainly because of the awful tags Microsoft put into its MAML markup language). Are there any others out there?
