NETWORK ENUMERATION WITH NMAP - Saving the Results

HI Guys

While running the XML to HTML conversation on my VM box that is connected to the VPN I am getting the following error. I google searched but it was giving 100s of solutions that were not in connection to this.

Any Ideas

xsltproc target.xml -o target.html
warning: failed to load external entity “target.xml”
cannot parse target.xml

Many Thanks
