you coul duse copy-of instead of value-of which avoids value-of making a 
text node, but in xslt1, it won't help as if you use xsl:variable 
without a select attribute the result is a result tree fragment, which 
isn't what you want.


If you are using xslt2  you can use if()... then... else ... within the 
select expression.

If you are using xslt1 and have access to a x:noe-set() extesnion 
function (almost all xslt 1 engines support this) then normally the 
thing to do is not define 40 global variables but rather just define one 
structured variable.

so don't use $a1, .....  $a40, use
$a/a1, ...$a/a40

where the global variable $a holds an in-memory XML fragment that you 
construct that contains all the data.
