Logstash XML parsing issues - trying to send to Graylog, part 2

Elastic Stack Logstash

@Badger so, swap out the if/else statements for the following?

	ruby {
	    code => '
	      event.get("[xml_content]").each { |a|
	        name = a["Name"]
	        value = a["Content"]
	        event.set( "[xml_content]#{name}", value)
	      }
	    '
  	}

I tried it, and got the following:

...
