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.

There are more ways, but I like most to use blocks

If you prefer to implement listeners as objects the documentation

below

should give you some sound hints too, I just never felt the need for

it.

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.html#M005185

and for the paramters they take have a look at the corresponding

method here:

http://www.ruby-doc.org/core/classes/REXML/SAX2Listener.html

parser.parse

END
