I've searched these forums quite hard looking for the solution to the following problem, and I'm close but with no cigar. I've hacked together a few solutions from other people but haven't really gotten to my goal.

What I would like to achieve is something as so:

1- Strip periods from filename  
2- strip underscores from filename  
3- convert filename to Title Case  
4- Insert periods between numbers and the letter V or v  
5- Convert all instances of a hyphen - into a hyphen flanked by a space on either side.

This would convert the following:

FILE.NAME.V.1.2.3-Temp.rar

into:

File Name V1.2.3 - Temp.rar

(Note: the above is the ideal output. V.1.2.3 is acceptable but if it can be worked out that would be lovely)

Doing this to a selection of files is a luxury, being able to do it to just the selected file I will be happy with.

Included is the code for the 2-button combo I have so far come up with. It sometimes works, but the double-space removing FINDREP fails if there are no instances of a double space. If I could have it fail quietly, that would also be OK.

`<xml>

			<instruction>@nodeselect</instruction>
		</function>
	</button>
</button>

Thanks in advance if any Einstein out there can crack it!
