nmap xml output has built-in style sheet...

... so when you open it with a browser it is formatted nicely. The stylesheet resides in the directory where nmap lives.

The actual xml looks like this when opened in Safari

If you run nmap with the --webxml option it will format the xml file for someone who may not have nmap on their box, so instead it references a stylesheet on the net.

Now my challenge is to export to a document, automatically link to a database, and format for publication with zero user intervention.
