I'm using REXML library.
<foo>
<baa>value</baa>
</foo>
I want to get the value that belongs to <baa>.
How can I do it?

I assume your XML is supposed to be "<foo><baa>value</baa></foo>", i.e. with ending tags.Chris Lutz– Chris Lutz2009-07-01 06:11:58 +00:00Commented Jul 1, 2009 at 6:11

try this
require 'rexml/document'
doc = REXML::Document.new File.new('mydoc.xml')
doc.elements('*/foo/baa') { |element| puts element.get_text }
I prefer Nokogiri and Hpricot gems myself. You can try them if you want.

require 'rexml/document'
xml = <<-EOS
<foo>
<baa>value</baa>
</foo>
EOS
doc = REXML::Document.new(xml)
doc.root.elements.each("baa") { |element| p element.text }
If you want to collect values you can use to_a.map or inject instead. See REXML::ELements.

Rishav's solution throws for me.
11:50:18 Temp$ ruby rx.rb
rx.rb:5:in `elements': wrong number of arguments (1 for 0) (ArgumentError)
from rx.rb:5
11:50:25 Temp$
Here are some alternative approaches:
require 'rexml/document'
doc = REXML::Document.new DATA
doc.elements.each('//foo/baa') { |element| puts element.get_text }
baas = REXML::XPath.each(doc, '//foo/baa/text()') {|txt| p txt}
p baas
__END__
<foo>
<baa>value</baa>
</foo>
