I'm getting the error "Can't resolve type class instance" when I
attempt to do:
return <xml> … {[searchBox ()]} … </xml>
searchBox is defined as:
and searchBox () : transaction xbody = return <xml> … </xml>
There are two issues here.
First, [searchBox] is "in the [transaction] monad." That means you
can't just drop a call to it into a page.
Second, the "{[ ... ]}" notation is for applying conversion from an
arbitrary type to text via the [show] type class. In contrast, above
you are trying to insert a literal piece of XML, which instead uses the
"{ ... }" notation.
So, you will want code more like this:
x <- searchBox ();
return <xml> … {x} … </xml>
