So, in Hpricot:

  doc = Hpricot("<html>...</html>")
  doc.search("foo").each do |ele|
    new_ele = Hpricot \
      '<p>I found a ' + ele.name + " tag enclosing \'" +
      ele.inner_html + "' with " + ele.attributes.keys.join(' and ') +
      " values of " + ele.attributes.values.map { |x| "'#{x}'" }.join(' and ') +
      "...</p>"
    ele.parent.replace_child(ele, new_ele.children.first)
  end
  puts doc

REXML has a replace_child as well.  But now you've motivated me to add Element#replace.
