I am creating an XML file say A, from another xml file B. The content of
file B will be changing and some tags can have optional attributes. I
want to include the attribute in the constructed XML file tag(s) through
Xquery, only when it is available in source file B.

I am trying something like this, where the attribute "name" is optional
in source.


let $x:= doc("source.xml")

for $comp in $x/Unit/Data/Organization



<Company type="{$comp/@type}" primary="{$org/@primary}"
{if(fn:exists($x/Unit/Data/Organization/@name)) then name="{$org/@name}"
else "" } >
