Ruby：将XML解析为CSV

Posted 2021-02-26

I had an XML file that I needed to convert to CSV. In order to make things easier for myself, I used a pipe | symbol instead of a comma so that there would be no parsing errors later. I also ended up writing the file to a Txt file and importing it as such to Microsoft Excel.

require 'rexml/document'
 
xml_file = File.open("showcase.xml", "r")
csv_file = File.new("showcase.txt", "w")
 
xml = REXML::Document.new( xml_file  )
 
counter = 0
xml.elements.each("images") do |e|
  e.elements.each("image") do |f|
    counter = counter + 1
 
    csv_file.puts f.elements['src'].text  + "|" + f.elements['caption'].text  + "|" + f.elements['uri'].text + "|"
  end
end
