I am attempting to install an HTML validator on a secure server with no Internet access. I tried to install the W3 validator, but that had many perl dependencies that in turn had more perl dependencies that it was proving rather difficult to download them all then transfer them to the server and install them manually.
I need a validator with little to no extra dependencies that I can download to my personal computer then transfer the files, install and quickly setup on a server with no Internet access.
Our validation server is within a LAN that has no Internet access.
