Libxml SaxParser Problem

ruby-talk
1

Hi,

i've installed libxml-ruby (0.5.2.0) and want to test the SaxParser.
So I found following example:

#!/usr/bin/env ruby
require 'rubygems'
require 'xml/libxml'
start = Time.now
ARGV.each {|filename|
  counts = Hash.new
  parser = XML::SaxParser.new
  parser.filename = filename
  parser.on_start_element {|element_name, _|
    if counts[element_name]
      counts[element_name] += 1
    else
      counts[element_name] = 1
    end
  }
  parser.parse

  File.open(filename + ".count.csv", "w") {|f|
    counts.each {|element_name, count|
      f.puts "\"#{element_name}\",#{count}"
    }
  }
}

but if I start this script, I got following error:

undefined method `on_start_element' for #<XML::SaxParser:0xb7a88858>
(NoMethodError)

but why? a saw a few examples with "on_start_element".

thanks!

You might have the wrong lib in your mind: http://p.ramaze.net/9 would work
