How do I remove part of a path?

Yes, it should be:

replace "/" & item 4 of <wherever your url is> with empty in <wherever your
url is>

The other way works if he's always looking to replace the same string, this
is better if the string is always in a known position but the string itself
could vary.

I have so many instances where I need to set the itemdelimiter to tab that I
wrote a handler to deal with it.

function tabItem pitem,pstring
   set the itemdelim to tab
   return item pitem of pstring
end tabItem

put tabItem(4,mystring) into myItem

Since itemdelim is local to the handler, no need to store it away and
restore it.  Nothing fancy but probably saved me a few hundred lines of
code, and forgetting to restore the itemdelim in the calling handlers.

I wish there was a way to "put column 4 of <string> into xyz" using the
columndelimiter setting (default tab) but I think columndelimiter only
applies to the split and combine commands for handling arrays.
