Rails - Jan 2011 - Help with libxml-ruby and SAX parser

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 <row> and </row>.

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:
-----------------------------------------------------------------
<report title="Event breakdown report"
name="aAffiliateEventBreakdownReport" time="2011-01-25
22:14">
  <matrix rowcount="310">
    <columns>
      <programName type="string">Programm
Name</programName>
      ...
    </columns>
    <rows>
      <row>
        <programName>Shop 1</programName>
        <programId>45001</programId>
        ...

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?
