from_xml(xml, disallowed_types = nil) public

Returns a Hash containing a collection of pairs when the key is the node name and the value is its content

xml = <<-XML
  <?xml version="1.0" encoding="UTF-8"?>
      <foo type="integer">1</foo>
      <bar type="integer">2</bar>

hash = Hash.from_xml(xml)
# => {"hash"=>{"foo"=>1, "bar"=>2}}

DisallowedType is raise if the XML contains attributes with type="yaml" or type="symbol". Use Hash.from_trusted_xml to parse this XML.

Looks like this method has trouble with attributes:


require 'rubygems'
require 'bundler'
require 'active_support/core_ext'
require 'pp'

xml  = 
  '<test id="appears">
    <comment id="doesnt appear">
      it worked
    <comment />

hash = Hash.from_xml(xml)

pp hash

#=>{"test"=>{"id"=>"appears", "comment"=>["it worked", "see!", nil]}}

# Notice how the id attribute on the first comment element doesn't appear.
