Find and sort all files in folder without invisible files

Question

Hi all,
I am trying to check whether the newest file added to a folder is an HTML file. In theory the folder should be empty when a new file is added because the script will delete all files in the folder just before it finishes running.
However, I am having a problem with .DS_Store files being created automatically in the folder. When Finder accesses the folder it creates a new .DS_Store file and thus the newest file added to the folder is never an HTML file.
I believe that the command "without invisibles" could help me with this problem. However, I have not been able to implement this successfully. I would appreciate if someone could please point me in the right direction. Here is what I have so far.
tell application "Finder"
          set sortedFiles to reverse of (sort (files of thisFolder) by modification date) as alias list
          set newestFile to item 1 of sortedFiles
-- check if newestFile is an HTML file
-- read file and send contents to another application
end tell
Thanks for your help!

Errr...  A quick reality check is called for. If you make files visible to the finder then they are no longer invisible files, so ignoring invisible files won't help you one bit. your best bet is to do a manual check for a file that starts with a "." (which would normally be invisible):
tell application "Finder"
          set thisFolder to folder "Pictures" of home
          set sortedFiles to (sort (files of thisFolder) by modification date) as alias list
          set newestFile to last item of sortedFiles
          if name of newestFile starts with "." then
                    set newestFile to item -2 of sortedFiles
          end if
end tell
