Public Instance Methods
Expose the entire document
# File lib/extreml.rb, line 95 def document return TypeElement.new({name: 'document', content: @document}, main_element: self) end
Returns the document in an Hash form
# File lib/extreml.rb, line 73 def to_hash return self.document.to_hash end
# File lib/extreml.rb, line 77 def to_json return self.document.to_json end
Retrurns the document in XML format
# File lib/extreml.rb, line 82 def to_xml if @xml_header.nil? xml = '' else xml = @xml_header.to_xml + "\n" end self.document.__types.each do |t| xml += self.document.send(t).to_xml end return xml end
Print the entire document tree. For debug purposes
# File lib/extreml.rb, line 130 def tree attributes: false self.document.__tree attributes: attributes end
update content from a subsequent element
# File lib/extreml.rb, line 100 def update_content key, content # byebug # @document = content.to_hash # upd = false # @document.each do |e| # byebug # if e[:name] == key # upd = true # content.each do |k,v| # e[k] = v # end # break # end # end # # unless upd # @document << content # end # if @document[key].nil? # @document[key] = content # else # unless @document[key].class = Array # @document[key] = [@document[key]] # end # @document[key] << content.to_hash # end end
