[R] newbee to XML library

[witold eryk wolski]

Hi!
I wanted to read out from an xml document values of some tags using the xml 
library in R.
Has anyone out ther a example that is doing something like:
take a xml file and return all values of the set of elements named eg 
myvalue as an array.

The document that i have to parse looks like:

<open>
	<firstchild>
		<secondchild>
			<myvalue>0.44</myvalue>
		</secondchild>
		<secondchild>
			<myvalue>0.55</myvalue>
		</secondchild>
	</firstchild>
</open>

Eryk.
