strip is for stripping null values in lists, not newlines. I don't  
think ST will ever support anything like
newline stripping.
strip() is most useful for use with length(), which gives you the  
length of a multivalued attribute,
but length counts nulls, too. So if you want the length without  
counting nulls, you strip it before applying length.

strip is a function implemented in Java, not a template. This error  
indicates that your version of ST
doesn't support the strip function yet. It came in in a late 2.3b  
version, 3.0 definitely has it.
Which version are you using?
