Problem parseing a XML - PullParser

Hi all,

I need to parse a XML file "line by line" because of a application
limitation, so i am trying to build a Stream/Pull xml parser with the
rexml library, but i can't get it to work..

 - Anyone knows what can be causing this error? -> Missing end tag for
''
 - This error even happens with a simple xml like this one:
psudo_xml = <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<SChange>
</SChange>
EOF



Error:
----------
DBG: event_type: text
  TXT Normal
DBG: event_type: end_element
  END Mode
/opt/local/lib/ruby/1.8/rexml/parsers/baseparser.rb:330:in `pull':
Missing end tag for '' (got "SChange") (REXML::ParseException)
Line:
Position:
Last 80 unconsumed characters:
  from /opt/local/lib/ruby/1.8/rexml/parsers/pullparser.rb:68:in `pull'
  from text2.rb:13:in `parse'
  from text2.rb:32:in `line_process'
  from text2.rb:47



Ruby code
----------
require "stringio"
require 'rexml/parsers/pullparser'

class BaseParser
  def initialize
    @parser = nil
  end

  def parse(raw_xml)
    @parser = REXML::Parsers::PullParser.new(raw_xml)

    while @parser.has_next?
      pull_event = @parser.pull
      puts "DBG: event_type: #{pull_event.event_type}"

      if pull_event.error?
        puts "\tERR #{pull_event[0]} - #{pull_event[0]}"
      elsif pull_event.start_element?
        puts "\tSTART #{pull_event[0]}"
      elsif pull_event.end_element?
        puts "\tEND #{pull_event[0]}"
      elsif pull_event.text?
        puts "\tTXT #{pull_event[0]}"
      end
    end
  end
end

def line_process(ios,myparser)
  while (line = ios.gets)
    line.chomp!
    myparser.parse(line)
  end
end


psudo_xml = <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<SChange>
  <Service>Testing:service</Service>
  <Status>Critical</Status>
  <Mode>Normal</Mode>
</SChange>
EOF

psudo_xml_io = StringIO.new(psudo_xml)
line_process(psudo_xml_io,BaseParser.new)
----------


Thanks for any help in advance.
