How to access xml in Feedjira parser classes

Say I have the following Feedjira nested parser subclasses. How can I access the xml for the Trunk, Branch, and Leaf classes so I can log/save it in the case of an error? Preferably just the xml for the parsed element, but I'd take the xml for the whole Trunk in the case of a Branch or Leaf.

Thanks!

module Feedjira  module Parser    class Trunk      include SAXMachine      include FeedEntryUtilities      element :trunkName      elements :branch, as: :branches, class: Branch      def createModel        begin          trunk = ActiveRecordTrunk.create( name: trunkName )          branches.each_index do |n|            branch = branches[ n ].createModel            branch.trunk_id = trunk.id            branch.save!          end        rescue StandardError => e          # log the error and the xml for this trunk element.  HOW??          ::Rails.logger.error "Parse Error, xml = #{ xml }"        end      end    end    class Branch      include SAXMachine      include FeedEntryUtilities      element :branchName      elements :leaf, as: :leaves, class: Leaf      def createModel        begin          trunk = ActiveRecordBranch.create( name: branchName )          leaves.each_index do |n|            leaf = leaves[ n ].createModel            leaf.branch_id = branch.id            leaf.save!          end        rescue StandardError => e          # log the error and the xml for this branch element.  HOW??          ::Rails.logger.error "Parse Error, xml = #{ xml }"        end      end    end    class Leaf      include SAXMachine      include FeedEntryUtilities      element :leafName      def createModel        begin          leaf = ActiveRecordLeaf.create( name: leafName )        rescue StandardError => e          # log the error and the xml for this leaf element.  HOW??          ::Rails.logger.error "Parse Error, xml = #{ xml }"        end      end    end  endend
