I tried the answer from Phrogz but could not get it to work (I was using a document fragment though but I'd have thought it should work the same?).

The "//" at the start didn't seem to be checking all nodes as I would expect. In the end I did something a bit more long winded but it worked, so here for the record in case anyone else has the same trouble is my solution (dirty though it is):

doc = Nokogiri::HTML::Document.new
body_dom = doc.fragment( my_html )

# strip out any attributes we don't want
body_dom.xpath( './/*[@align]|*[@align]' ).each do |tag|
    tag.attributes["align"].remove
end
