Subject: rexml child nodes

Hi,

I having been learning to use ruby for about 1 week (v. new). I am trying to
use ruby w rexml to read in xml documents of the form:

<QUIZ>

<QUESTION TEXT="What is 1 + 1" ANSWER="2" EXPLAIN="The answer is 2">
<CHOICE>3</CHOICE>
<CHOICE>1</CHOICE>
<CHOICE>2</CHOICE>
<CHOICE>6</CHOICE>
</QUESTION>

</QUIZ>

I am able to get the Questions with:

require "rexml/document"
include REXML
doc = Document.new File.new("CVPhys.xml")
quiz=[]
doc.elements.each("QUIZ/QUESTION") { |element| quiz.push
element.attributes["TEXT"] }
puts  quiz

But, I can't figure out A) how to get at the vaules in the <CHOICE> nodes -
the code below just gives me results of the form "<CHOICE>6</CHOICE>"

require "rexml/document"
include REXML
doc = Document.new File.new("myQuiz.xml")
quiz=[]
doc.elements.each("QUIZ/QUESTION/CHOICE") { |element| quiz.push element}
puts  quiz

And B) how to read the xml doc line by line to output as a file with the
ultimate form:


What is 1 +1
3
False! The answer is 2
1
False! The answer is 2
2
True! The answer is 2
6
False! The answer is 2


Thanks !
