It looks like you want to extract the content of each 'Key' element as
a single string, in which case you need to concatenate the values of
the text/content nodes within each element. Like this:

  [lists:concat([Value || #xmlText{value=Value} <- Content]) ||
#xmlElement{content=Content} <- xmerl_xpath:string("//Key", Doc)].

Make sense?
