Generating an XML file

ruby-talk
1

Hi All,
I am reading an excel file and then generating a XML file. I am using
the below code. I am using Builder to do soo. Below i thought that as i
have a 'x' object of builder, i can write it to a yaml file using the
dump method.

CODE:
def generate_xml()
x = Builder::XmlMarkup.new(:target => $stdout, :indent => 1)
x.instruct!
x.comment! "A test xml for test cases"
x.FileName "#{@p}"
x.TotalCases "#{@t}"
x.Contents "#{@c}"
File.open('dump.xml','w') {|f| f.write(YAML.dump(x))}
puts "generated xml" #Just to print this in console
end

When i run below i get error -
C:/Ruby193/lib/ruby/1.9.1/psych/visitors/yaml_tree.rb:413:in
`dump_coder': undefined method `name' for #<IO:<STDOUT>> (NoMethodError)

OR what could be another approach to generate an xml file?

Thanks

You are already telling builder to write to $stdout, you shouldn’t even have a File.open in there. Also, the builder object x is not YAMLizable with that target, per se.

What you probably (?) want to be doing is more like this:

   f = File.new('dump.xml','w')
   x = Builder::XmlMarkup.new(:target => f, :indent => 1)
   ...
   f.close

If you are building an XML file why are you then converting it to YAML? Why
not write it out as is?
