Subject: REXML get specific element

All,

I'm trying for the first time to play with XML and Ruby.
Since I have only the core library at the moment, my choice went
directly for REXML.

So, here is my problem.
I'm willing to get a specific element in my xml file.

Normally I would do something like this:
doc.root.elements["programmer[@name='Matz']"]

But let's say I have a user interface, and I let a user enter the
programmer he wants to see. How can I look for an element using a
variable?
I hoped something like this would work:
entered_name = 'Matz'
doc.root.elements["magician[@name=#{entered_name}]"]
Unfortunately, it didn't...

After trying a few things, check with uncle google and in this forum,
I'm driving out of clues, so I'd appreciate if someone could show me the
correct way!

Thanks.
