- What's this?
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"?> <hash> <foo type="integer">1</foo> <bar type="integer">2</bar> </hash> XML hash = Hash.from_xml(xml) # => {"hash"=>{"foo"=>1, "bar"=>2}}
DisallowedType is raised if the XML contains attributes with type="yaml" or type="symbol". Use Hash.from_trusted_xml to parse this XML.
Custom disallowed_types can also be passed in the form of an array.
xml = <<-XML <?xml version="1.0" encoding="UTF-8"?> <hash> <foo type="integer">1</foo> <bar type="string">"David"</bar> </hash> XML hash = Hash.from_xml(xml, ['integer']) # => ActiveSupport::XMLConverter::DisallowedType: Disallowed type attribute: "integer"
Note that passing custom disallowed types will override the default types, which are Symbol and YAML.

Looks like this method has trouble with attributes:
ex:
require 'rubygems' require 'bundler' require 'active_support/core_ext' require 'pp' xml = '<test id="appears"> <comment id="doesnt appear"> it worked </comment> <comment> see! </comment> <comment /> </test>' 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.
