Prosper2 Actually your method is good but if your website takes more then 100 pages. Then it will be difficult to use. I think we should follow the almostbob's path through Google Webmaster Tool.
Another Method is that... Go to the Google Drive >Create a new spreadsheet>Paste the following function in first cell: [=importXml("https://www.google.com/search?q=site:clippingpathindia.com.com&num=100&start=1","//cite")
Must replace clippingpathindia.com by your domain name.
