I seem to recall doing something like this with a recursive call. It's
obviously resource intense if you get a huge amount of traffic but works
fine. I had a rough working recipe before other parts of life took me away.
I can look for what I did if it might help.

&gt; The string &quot;are&quot; appears 16 times in my BasicEditing.<br>
