Re: Simple suggestion for XSLT

Why would this be useful given that

substring-after(substring-after("1999/04/01", "/"), "/") returns "01"

and

substring-before(substring-after("1999/04/01", "/"), "/") returns "04"

and

concat(substring-before("1999/04/01", "/"),
       "/",
       substring-before(substring-after("1999/04/01", "/"), "/"))
returns "1999/04"

?
