Subject: rexml help

Hi all,

After futzing with REXML and reading over the API I'm not quite
"getting it".  I have a file that looks more or less like this:

<dbrc>
   <database>
      <name>foo</name>
      <login>john</login>
      <password>blah</password>
   </database>
   <database>
      <name>bar</name>
      <login>jane</login>
      <password>hello</password>
   </database>
   <database>
      <name>foo</name>
      <login>jack</login>
      <password>pfft</password>
   </database>
</dbrc>

Given a name, I want to be able to grab the login and password.  Or,
given both a name and a login, I want to be able to find the password.
 In the event I am only given a name, and there is more than one entry
with that name, I want the first entry (from a top down perspective).

What is the shortest route to accomplish this with rexml?  I've been
futzing around with each, each_element, root, get_text - but I'm just
not quite getting the hang of it.

To look at all of the text I did something like this:

doc = Document.new(File.new("dbrc.xml"))

doc.elements.each("/dbrc"){ |node|
   node.each_element{ |element|
      element.each_element{ |e|
         puts e.get_text.value
      }
   }
}

But, I need to narrow it down more and be able to focus in on only the
elements I need.

What's the best/quickest/easiest way to accomplish this?

Regards,

Dan
