Try Loofah, which is based on Nokogiri:

require "loofah"

xml =3D <<-eoxml
<document>
 <abcde>
   <fghij>
     some text blah blah
   </fghij>
 </abcde>
</document>
eoxml

doc =3D Loofah.xml_document(xml)
scrubber =3D Loofah::Scrubber.new do |node|
  node.name =3D "h1" if node.name =3D=3D "abcde"
  if node.name =3D=3D "fghij"
    node.before node.inner_html
    node.remove
  end
end
doc.scrub!(scrubber)
puts doc.to_s
# =3D> <?xml version=3D"1.0"?>
# <document>
#  <h1>
#    some text blah blah
#  </h1>
# </document>
