Parsing XML Files in Rails

I’m a super newbie with ruby on rails and ruby in general. Basically,
I’m
trying to display a pre-generated xml file within my rails app. Super
simple, but I can’t get it to work. I created a new controller called
“nmap” and it has this code:

class NmapController < ApplicationController

require ‘nmap/xml’
def create
@nmapfile = Nmapfile.new(nmapfile_params)
@nmapfile.nmapfilerecords = 0
@nmapfile.save
sleep 8
Nmap::XML.new(’/opt/ruby_projects/nmap/nmap_parse/app/views/nmap/test.nmap.xml’)
do |xml|
xml.each_host do |host|
if “#{host.status}” == “down”
else
@nmapfile.nmapfilerecords += 1
end
end
end

respond_to do |format|
if @nmapfile.save
format.html { redirect_to @nmapfile, notice: ‘nmap file was
successfully created.’ }
format.json { render action: ‘show’, status: :created, location:
@nmapfile }
else
format.html { render action: ‘new’ }
format.json { render json: @nmapfile.errors, status:
:unprocessable_entity }
end
end
end

I’ve placed my xml file in
“/opt/ruby_projects/nmap/nmap_parse/app/views/nmap/test.nmap.xml” as you
can see above. However, when I load the webapp, I receive the following
errors within the application trace:

/opt/ruby_projects/nmap/nmap_parse/app/controllers/nmap_controller.rb:30:
syntax error, unexpected $end, expecting keyword_end

This could be extremely simple to do, so I’m looking for someone to help
point me in the right direction.

This error means that your missing an “end”. This sort of mistake is a
lot
easier to spot if you indent your code properly.
