parsing of XML return a singleton Hash that is not dumpable about crack HOT 4 CLOSED

Hi,

investigated further, and it seems it is all because of these lines:

if t.is_a?(String)
        class << t
          attr_accessor :attributes
        end
        t.attributes = attributes
      end

line 85 - 90 of the xml.rb file.

Apparently, after the insertion of the attributes accessor on the t variable, t is no longer an instance of String, but a singleton instance(?) of String. Not dumpable, therefore. How to fix this? I'll investigate further, just wanted to tell u about so u could know of the issue as well.

The main culprit of this issue has been (and now a quote from the Marshal class documentation for Ruby 1.x.x):

Some objects cannot be dumped: if the objects to be dumped include bindings, procedure or method objects, instances of class IO, or singleton objects, a TypeError will be raised.

the solutions, as far as i see it is, are:

• either do it all with instance_variable_get/set methods when it comes to accessing the attributes,
• or create a subclass that inherits from String, define the attributes accessor inside and move on from there.

what do you think?

Anyone have a solution or workaround for this in the past 7 months?

Seems to be fixed already
