Subject: swapping tags & deleting tags via nokogiri


let's say I have an xml document like this

<document>
  <abcde>
    <fghij>
      some text blah blah
    </fghij>
  </abcde>
</document>

is there a simple method in nokogiri to:

step 1: convert all <fghij> tags to something else (e.g., <h1>)
creating this…
<document>
  <abcde>
    <h1>
      some text blah blah
    </h1>
  </abcde>
</document>

step 2: remove all <abcde> tags but keep the internal tags, creating
this
<document>
    <h1>
      some text blah blah
    </h1>
</document>


I imagine that step 2 is done all the time and there's probably a
simple way to do it, but I'm not sure where to begin with either.

file = Nokogiri::XML(File.new(file_name))  # <= this is about as far
as I've gotten (not very...)

Thanks!!
