Converting a Sharepoint List into XML

This easiest way is to use the URL below & insert your list GUID
http://servername/site/_vti_bin/owssvr.dll?Cmd=Display&List=*YOURUNIQUELISTID*&XMLDATA=TRUE
To get the GUID of the list you need to go into the list & click ‘Settings’ -> ‘List Settings’.
Now if you look at your URL you will see something like:
/_layouts/listedit.aspx?List=%7B7B476F98%2D1075%2D4A6D%2D8F63%2D4C754B3F41FC%7D

The URL is encoded so you will need to replace “%7B” with “{” and “%7D” with “}” and “%2D” with “-” so the end result would look something like: {7B476F98-1075-4A6D-8F63-4C754B3F41FC}
