Modify and wrap xml nodes with nokogiri

I have an xml document with fragments like the following:

<x>
  abcd
  <z>ef</z>
  ghij
</x>

I want to find the text "defg" inside the node, and modify that node to the following:

<x>
  abc
  <y>
    d<z>ef</z>g
  </y>
  hij
</x>

This means creating a new node that has bit of x.text and other children inside.

I can find the node which includes the text, but I don't know how to break it up, and wrap just the matching section inside the <y> tags.

Any ideas that can point me in the right direction are most appreciated. Thanks.

What about turning it into a sting and then use a regex to change it, and then parse it with nokogiri again.

sting = some_xml.to_s
# => '<x>abcd<z>ef</z>ghij</x>'

splits = sting.match(/(.)<z>(.*)<\/z>(.)/)

new_string = sting.gsub(splits[1], "<y>#{splits[1]}").gsub(splits[3], "#{splits[3]}</y>")

Nokogiri::XML(new_string)
