#from_xml(xml, tmpl = nil) ⇒ Object

Create an instance of this class based on xml content Careful! If you call this from a constructor, be sure to provide something ‘ie. self’ as the @tmpl. Otherwise, you will get an infinite loop!

Parameters:

  • xml (String, File, Nokogiri::XML::Node) —

    the xml content to build from

  • tmpl (ActiveFedora::OmDatastream) (defaults to: nil) —

    the Datastream object that you are building @default a new instance of this class
