Hello guys ! I'm new in Ruby....Hope you can help because i'm trying a
lot and just can't see where is the problem..
I have this xml, and not only this, i want just for any xml file that i
might put :

<?xml version="1.0"?>
<records>
   <company>
     <id>p1</id>
     <name>Skoda</name>
     <price>10000</price>
     <stock>4</stock>
     <country>Czech Republic</country>
  </company>
  <company>
     <id>p2</id>
     <name>Mercedes</name>
     <price>50000</price>
     <stock>5</stock>
     <country>Germany</country>
  </company>
  <company>
     <id>p3</id>
     <name>Alfa Romeo</name>
     <price>18000</price>
     <stock>19</stock>
     <country>Italy</country>
  </company>
  <company>
     <id>p4</id>
     <name>Fiat</name>
     <price>1500</price>
     <stock>15000</stock>
     <country>Italy</country>
  </company>
</records>


AND USING THE CODE BELOW:

require 'nokogiri'
require 'pp'

xmldoc = Nokogiri::XML(IO.read("xmlinputfile.xml"))
columns = xmldoc.xpath('/*/*[position()=1]/*').map(&:name)

print "give csv output file\n"
csvoutputfile = gets.chomp
File.open(csvoutputfile, 'w') do |f|
   rows =[]
   xmldoc.xpath('/*/*').each do |row_xml|
          row_values = []
          f.puts "  #{rows << row_values}"
          row_xml.xpath('./*').each do |field|
                f.puts "#{row_values << field.text}"

          end
   end
   pp rows


 end




 I WANT TO CONVERT IT TO CSV FORMAT LIKE THIS:

id,name,price,stock,country
p1,Skoda,10000,4,Czech Republic,
p2,Mercedes,50000,5,Germany,
.
.
.
. and so on



THE RUBY CODE OF CONVERTION WORKS FINE BUT ONLY WHEN I RUN IT IN THE
COMMAND PROMT, ONLY THERE IS SHOWS THE CSV FORMAT RIGHT

BUT I WANT TO WRITE IT IN A TXT FILE AND THIS IS WHAT I GET WHEN I TRY
WRITING IT INTO A txt :


    [[]]

["p1"]
["p1", "Skoda"]
["p1", "Skoda", "10000"]
["p1", "Skoda", "10000", "4"]
["p1", "Skoda", "10000", "4", "Czech Republic"]
[["p1", "Skoda", "10000", "4", "Czech Republic"], []]
["p2"]
["p2", "Mercedes"]
["p2", "Mercedes", "50000"]
["p2", "Mercedes", "50000", "5"]
["p2", "Mercedes", "50000", "5", "Germany"]

[["p1", "Skoda", "10000", "4", "Czech Republic"], ["p2", "Mercedes",
"50000", "5", "Germany"], []]
["p3"]
["p3", "Alfa Romeo"]
["p3", "Alfa Romeo", "18000"]
["p3", "Alfa Romeo", "18000", "19"]
["p3", "Alfa Romeo", "18000", "19", "Italy"]
[["p1", "Skoda", "10000", "4", "Czech Republic"], ["p2", "Mercedes",
"50000", "5", "Germany"],
["p3", "Alfa     Romeo", "18000", "19", "Italy"],[]]



PLEASE CAN ANYBODY SHOW ME MY MISTAKE AND WHAT SHOULD I DO BECAUSE I
CANNOT FIND IT... AND I
DON'T UNDERSTAND THE REASON THAT IT SHOWS IT LIKE THIS IN THE txt FILE.

THANK YOU IN ADVANCE !!
