This was the reason I was lamenting that  rev's filter "command" is not 
fully regex compatible.
Your replaceText part returns a "|" delimited list. But the  "|" (or)  
does not work in the filter command.
Not as in filter x without "5|6|11|18" nor as in filter  x without 
"[56]|1[18]".
The  "|" seems even to be ignored between [ ] brackets.
