You can use a while loop - something like:
command | while read file; do
print $file:t:r
done
If you're using a command that, unlike print, can't be invoked for each
file separately then you can use something like the following:
print ${^$(command)}(:t:r)
The caret is only needed if you don't set rcexpandparam.
To cope with files with spaces in their names you need to use something
like ${(f)^"$(command)"}(:t:r)
