In fact, inner_text works as well. But you should have a look at the
warnings from ruby! The inner_text or inner_html function is applied
to 'puts (t/"dc:subject")' return object, which is nil.
So a warning appears:
rdf.rb:6: undefined method `inner_html' for nil:NilClass
(NoMethodError)

but 'puts (t/"dc:subject")' is executed, and so '<dc:subject>html
internet tutorial web</dc:subject>' is displayed anyway. Therefore I
recommend using a few parentheses there:

puts((t/"dc:subject").inner_text)

and it should work well this time.

Next time, look at the warnings!!! ;)
