[xsl] is there an equivilent to eval() ?

[Terence <tk.lists@xxxxxxxxxxx>]

Hi everyone,

I have the following expression.

<input type="text" name="{$main}" value="##blah##" />

Where the variable $main contains the name of the element who's content 
I want to replace ##blah## with.

as it happens, $main could either == 'system' or 'main' so there are 
possibilities of either <main/> or <system/> elements whos content I 
want to extract (and wrap in normalize-space()).
