Fun. I like curl.
For those who don't have broad use for curl, Python is also an option. The following script can be used to download and save files from the web if you know the url:
from System.Net import WebClient
def downloadFile(url,filename):
#change the following to the path where you want to save your files
path = "C:\\[yourchosendirectory]\\[filepath]"+filename
WebClient().DownloadFile(url,path)
So, for this purpose, you'd could do the following:
<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 2.1.0.7-->
