Instance Method Details

#extract_root_from_soap(envelope) ⇒ Nokogiri::XML::Document

This is not the ideal approach. Ideally Nokogiri parser would be able to understand SOAP xsd as well

Returns:

  • (Nokogiri::XML::Document) —

    Retrieve root element from SOAP

def extract_root_from_soap(envelope)
  body = envelope.children.find { |child| child.name == 'Body' }
  root_element = body.children.reject { |child| child.is_a?(Nokogiri::XML::Text) }.first
  envelope.namespaces.each { |namespace, value| root_element[namespace] = value }
  body.namespaces.each { |namespace, value| root_element[namespace] = value }
  Nokogiri::XML root_element.to_s # Convert to Xml Document
end

#valid?(xml) ⇒ Boolean

Returns Whether xml is valid according to WSDL of class.

Parameters:

  • xml (String, Nokogiri::XML::NodeSet)
