Help with libxml-ruby and SAX parser

Rails
#1

Hello,

I try to read through an XML document with the libxml-ruby SAX parser.
It is possible to execute the parser and I can see the output of the
element according to the “puts” in the Saxparser class.

However I do not know how to get the results after the
“on_start_element” and write them in to a hash. I’m browsing through
Google since 3 days without any luck to find an example or
understandable documentation how to get the data.

I need to get the data between and .

Is there anybody that can help me?

Thanks

I have done following:

Created a saxparser.rb model that looks like this:

require ‘rubygems’
require ‘xml/libxml’

class Saxparser
include XML::SaxParser::Callbacks

def on_start_element(element, attributes)
if element == ‘row’
puts element
end
end
end

Created method to execute the sax parser:

def self.vbdownload_td_xml
require ‘net/http’

# download the xml file
download_td_xml

parser = XML::SaxParser.file("#{RAILS_ROOT}/tmp/td.xml")
parser.callbacks = Saxparser.new
parser.parse

end

The XML itself looks like this:

Chris, the SAX Parser has an “on_characters” callback. You need to note
when you see an on_start_tag for the tag “row”. Then, in your
on_characters callback, you use the characters it presents you. When
you see an end tag for “row”, you need to turn off your note. Get it?
