You are right!! I had overlooked it. [*] has solved my problem. Many
thanks!!

One last question, I also had a mistake in the required XML output.
Maybe you can help me with that as well please:


XML Input is now slightly changed in <Rate_Structure_Event>, which
contains now few children called <Rate>:

<tree>
	<fruit ID="111">
		<mango ID="333">
			<colour>
				<Rate_Structure_Event
ConceptType="Rate_Structure_Event" ID="1">
					<Rate>bla</Rate>
					<Rate>bla</Rate>
					<Rate>bla</Rate>
				</Rate_Structure_Event>
			</colour>
		</mango>
		<orange ID="222">
			<color>orange</color>
		</orange>
	</fruit>
	<fruit_adjustment>
		<color>
			<Path>
				<Steps>111,333</Steps>
			</Path>
			<bla>false</bla>
			<Rate_Event ConceptType="Rate_Event"
ID="A"></Rate_Event>
			<Rate_Event ConceptType="Rate_Event"
ID="B"></Rate_Event>
		</color>
	</fruit_adjustment>
</tree>


Desired XML Output:

Exactly like before; but all <Rate> elements inside
<Rate_Structure_Event> shall be eliminated and replaced by all
<Rate_Event> inside <Fruit_adjustment> (Where the key is referring to
obviously, that's why we used Muecnhian Method). Only that the new
<Rate_Event> elements shall be actually renamed to <Rate>.

In other words the structure of the ouput doesn't change, the old <Rate>
are eliminated and new rates called <Rate_Event> replaces them without
forcing the element name to be changed from <Rate> to <Rate_Event>.

If this is not clear, I could give a simple example.

Many thanks for your advice,
Houman
