That's a good start. If you look at the flexform definition the "index" 
attributes define the tag name in the resulting array (numeric "index" 
attribute value indicates that it's a repeated block with numeric array 
keys)

After you change the array you can simply let DataHandler (aka TCEmain) 
take care of storing it again. No need to transform it back to XML at all!
