It is possible to specify the name of the Id attribute in the Xmldsig gem

[davideluque]

Change:

nemid/lib/nemid/authentication/response.rb

Line 9 in ee4ac33

@doc = NemID::XMLDSig::Document.new(string)

to:

@doc = NemID::XMLDSig::Document.new(string, id_attr: 'Id')

and change:

nemid/lib/nemid/authentication/response.rb

Line 11 in ee4ac33

@doc = NemID::XMLDSig::Document.new(Base64.decode64(string))

to:

@doc = NemID::XMLDSig::Document.new(Base64.decode64(string), id_attr: 'Id')

And the following code is not needed anymore:

nemid/lib/nemid/xmldsig.rb

Lines 12 to 31 in ee4ac33

	# The "referenced_node" method needs to be overridden since NemID uses
	# "Id" (as opposed to ID or wsu:Id) as the attribute name in the "Signature"
	# element of the XML document.
	Xmldsig::Reference.class_eval do
	def referenced_node
	if reference_uri && reference_uri != ""
	id = reference_uri[1..-1]
	if ref = document.dup.at_xpath("//*[@ID='#{id}' or @Id='#{id}' or @wsu:Id='#{id}']", NAMESPACES)
	ref
	else
	raise(
	ReferencedNodeNotFound,
	"Could not find the referenced node #{id}'"
	)
	end
	else
	document.dup.root
	end
	end
	end
