hi,
I'm using sax parsing in my code but confused about how to add
listener's to it and can you tell me in detail how to write sax code in
ruby as well as listener's.

require 'rexml/parsers/sax2parser'

parser = REXML::Parsers::SAX2Parser.new( DATA.read )

parser.listen :start_element do
|uri, locname, qname, atts|

puts "I am in start_element and was called with " <<
[uri, locname, qname, atts].inspect
end

parser.listen :characters do
| text |
puts %<I am in characters and was called with "#{text}">
end
#
# For all type of listeners see here:
# http://www.ruby-doc.org/core/classes/REXML/Parsers/SAX2Parser.ht...
# and for the paramters they take have a look at the corresponding method here:
# http://www.ruby-doc.org/core/classes/REXML/SAX2Lis...
parser.parse
