xmlns in root node

[maxmeyer]

Hi there,

how do I have to use roxml to get

 xmlns:namespace=example.com

as parameter in root node when using

Object.to_xml.to_s

I tried to figure out how to do it by myself, but I didn't find a way to do it (I had a look at spec/namespaces).

I used the following input file (btw: this is how the output should look like)

<?xml version="1.0" encoding="UTF-8"?>
<ns2:user xmlns:ns2="http://foo.example.com">                                                                                               
  <attribute>attr</attribute>
</ns2:user>

and the following script

require 'roxml'
require 'pry'
require 'pp'

class User
  include ROXML

 #not needed but my real classes look like UserSimple etc.
  xml_name 'user'
  xml_namespace :ns2
  xml_namespaces :ns2 => 'http://foo.example.com'

  xml_accessor :attribute, :namespace => false                                                                                              
end


user = User.from_xml(File.read(File.expand_path('example-user.xml', File.dirname(__FILE__))))
pp user.to_xml.to_s

Help would be very welcome, as I'm stuck in the moment and need the stuff working for my master thesis.

Thanks.

Cheers,
Max meyer

According to the README ROXML does not support outputting namespaced nodes. Apparently this is planned for a future version.

I've needed the same functionality myself and I've had to override to_xml and build the XML + namespaces manually. Not elegant but it works.

[maxmeyer]

Mmmh, thx for the clarification. I consulte the README, but may have overseen that...

@ruckus We're running into the same issue over here.

Could you detail what you did to override to_xml to build the XML with namespaces? Perhaps point us to some code?

We've got some time to work on this, if we feel like this would be a beneficial contribution for the project.

[ruckus]

@benWoz my approach ended up being fairly manual.

Check out this stuff:

https://github.com/ruckus/quickeebooks/blob/master/lib/quickeebooks.rb#L27

That Model class is a base class, an example concrete class is

https://github.com/ruckus/quickeebooks/blob/master/lib/quickeebooks/model/account.rb

When I have an instance of Account and want to convert it to XML I call to_xml_ns.

This works but feels kinda janky. In the base Model I call to_xml but write it out to a temporary StringIO object that I can mutate even more.

Hope this helps

@ruckus, thanks for the quick response. I'll take a look at it and see what can be done!

Any further forward with this?

I'm trying to output the following, e.g.

<example xmlns="http://example.com/">
    <other>stuff</other>
</example>

Right now, I'm doing the following nasty hack:

  to_xml.to_s.sub("example", "example xmlns='http://example.com'")

[benWoz]

I think we ended up taking a different route. Can't remember exactly what &
don't have access to the client's code at this point...

Wish I had more info for you.

That's cool don't worry. My nasty hack works for now... :)

A nicer alternative to @bishboria's hack is this...

class Example
  include ROXML
  xml_reader :xmlns, :from => :attr

  def initialize
    @xmlns = "http://example.com"
  end
end

For other folks that run into this - the easiest way I found (outside of forking + patching) is to override to_xml on the class

class Example
  include ROXML
  xml_accessor :some_attribute
  
  def to_xml(params = {})
    params[:namespaces] = { "ns1" => "http://example.com" }
    super
  end
end
