XPath 3 has an

   if (condition) then exp1 else exp2

expression so perhaps simply


<p:option name="sorted-files" select="true()" />


             <p:with-input select="if ($sorted-files) then //*:file else
(//*:file => sort((), function($file) { analyze-string($file!@name,
'[0-9]+')!descendant::*[not(*)]!(if (.

                     instance of element(fn:match)) then number(.) else
string(.)) }))"/>
