I've got an xml file. How could I generate xml_builder ruby code out of that file?
Notice - I'm sort of going backwards here (instead of generating xml, I'm generating ruby code).
Pretty formatting isn't a big deal - I can always run it through a formatter later.
Here's what I eventually came up with:
#!/usr/bin/env ruby
require "rexml/document"
filename = ARGV[0]
if filename
f = File.read(filename)
else
raise "Couldn't read file: `#{filename}'"
end
doc = REXML::Document.new(f)
def self.output_hash(attributes={})
count = attributes.size
str = ""
index = 0
attributes.each do |key, value|
if index == 0
str << " "
end
str << "#{key.inspect} => "
str << "#{value.inspect}"
if index + 1 < count
str << ", "
end
index += 1
end
str
end
def self.make_xml_builder(doc, str = "")
doc.each do |element|
if element.respond_to?(:name)
str << "xml.#{element.name}"
str << "#{output_hash(element.attributes)}"
if element.length > 0
str << " do \n"
make_xml_builder(element, str)
str << "end\n"
else
str << "\n"
end
elsif element.class == REXML::Text
string = element.to_s
string.gsub!("\n", "")
string.gsub!("\t", "")
if !string.empty?
str << "xml.text!(#{string.inspect})\n"
end
end
end
str
end
puts make_xml_builder(doc)
After generating that, I then formatted it in Emacs.
