Sounds awesome, but the board is way too huge. That is why I try to push the size limits in this video to the minimum.

Postprocessing XML can be a thing, but since .NET has great XML support, you can use PowerShell for that (which for me often is way easier than going the XSLT route, for instance because Windows lacks built-in console XSLT tooling).

Based on the help and the below links, my query command then on these machines turned out to be this: Read the rest of this entry »
