json output

[MortalCatalyst]

Just wondering why saxerator doesn't feature a :json output option?

[soulcutter]

Because nobody has contributed that feature yet!

But also there are issues with translating XML to JSON, because JSON does not have a direct corollary to element attributes. Saxerator gets around this by using extended classes for String and Hash which have attributes collections, but it's less-clear to me a way to represent this in JSON.

I'm open to proposals!

similarly, I'm looking for a flat :string output so I can parse the result in my own classes!

• XML: Element names can contain letters, digits, hyphens, underscores, and periods.
• JSON: Any valid string is a valid key

Proposal: Use @ char for attributes

XML:

<products>
  <product>
    <name>iPhone</name>
    <price currency="USD">1337</price>
  </product>
</products>

OUTPUT:

parser.for_tag('product').each do |item|
  p item # => { 'name' => 'iPhone', 'price' => 1337, 'price@currency' => 'USD' }
end

@v3rmin With this flow ti'll require to parse attribute names and it'd hard to understand that this it actually relate to the same node.
What if we'll represent our custom strings and hashes like and object?

parser.for_tag('product').each do |item|
  p item # => {
     'name': 'iPhone',
     'price': {
       value: 1337,
       attributes: {
          'currency: 'USD'
       }
     }
   }
end

Also we're talking about JSON it should be a String, not a Hash.
@soulcutter how you like this?

[v3rmin]

I think it must be a markup that doesn't collide with valid XML.
What if the XML looked like this:

xml = <<-XML
<product>
  <name>iPhone</name>
  <price currency="USD">
    <value>1337</value>
    <attributes>
      <currency>EUR</currency>
    </attributes>
  </price>
</product>
XML

require 'saxerator'

parser = Saxerator.parser(xml)
parser.for_tag('product').each do |item|
  p item # => {"name"=>"iPhone", "price"=>{"value"=>"1337", "attributes"=>{"currency"=>"EUR"}}}
end
