In XPath 2.0,

.//load except .//gui//load

or 

for $this in . return $this//load[ancestor::gui[1] is $this]

This is a peculiar construct needed because XPath does not have real
variables; in XQuery you could write

let $this := .
return $this//load[ancestor::gui[1] is $this]

In XSLT (1.0 or 2.0) you could write

.//load[ancestor::gui[1] is current()]
