Subject: Search for an Presence of an XML element in a array

hi,

I am reading an XML document and storing in a array.
Now I need to search for presence of a particular element and

array = {elements of XML Document}
array[1] = {chile elelments of XML document}

*** I want to ***
search if element X or Y or Z exists
if
  X exists
    Do this
  elsif Y exists
     Do this
    else
      Do This
end

I am not finding any way to search for elelemtns in XML file.
Please provide your solution.

My XML file looks like this

  <TXN value = '3'>
    <SEND request = 'X' > <!- This can be either X or Y or Z  -->
      <MODIFY val1 = 'from' val2  = 'Show' val3 = '200'/>
    </SEND>
  </TXN>

I am using REXML solution to play with Ruby file.

regards,
Naresh
