[xsl] Refactoring parsing code with XSLT 2.0

[Micah Dubinko <micah@xxxxxxxxxxxx>]

I know how I would do this in XSLT 1.0, and it's not very pretty. Is 
there an elegant way in XPath/XSLT 2.0 to do this?

I have a variable with a string value like "3.48in" or "1pt" or "4" or 
"#123456" etc. Of the values that contain units, the first 2 of this 
particular list, I want to separate out the value from the units. I can 
include a list of possible unit values, say ("in", "cm", "pt", "em", 
"px") or whatever.

I've done XSLT 1.0 for a long time, and am just now getting into 2.0, so 
go easy on me. :) I'll post any interesting things I discover in my blog
