I don't think he wants sed.  What he asked for is to remove every
*character* except those in the string.  He's not looking to remove
strings, but to remove characters.  For this he should use tr(1) with a
"-d" option.

For example, to remove all characters a,b,c,d from a file, pipe it through
the following:

	tr -d abcd

Of course, depending on what's in the string, you may want to quote it.
