[R] XML to data frame or list

[bogdan romocea]

Dear useRs,

I have a simple/RTFM question about XML parsing. Given an XML file,
such as (fragment)
<A>100</A>
<B>23</B>
<C>true</C>
how do I import it in a data frame or list, so that the values (100,
23, true) can be accessed through the names A, B and C?

I installed the XML package and looked over the documentation...
however after 20 minutes and a couple of tests I still don't know what
I should start with. 

Can someone provide an example or point me to the appropriate
function(s)?

Thank you,
b.
