Removing set number of characters from end of string with ColdFusion

Simple request (hopefully) here.

I have a string which whilst it varies in length, will always need the last 6 characters removed.

Using a 3rd party web service, so I'm unable to edit the response in the XML before outputting.

If anyone can suggest a quick way of trimming them off i'd be really grateful!

here is the string i'll be using:

#daysEvent[iItem].XmlChildren[iEvent].XmlChildren[16].XmlText#

Thanks!

Left(mystring, len(mystring)-6)
