ruby script reading file line by line and add line

Question

I am reading a file in ruby by below code

completeLine = ""
file.each_line do |line|
  completeLine = completeLine + line
end

now when i print completeLine variable its show its content in multipal line like

<obj  id=\"pluvi\" border=\"0\"
clsid=\"clsid:VI\"
style=\"opacity: 0.0; background-color: #000000; width: 0px; height: 0px;\"></obj>"

i want it in 1 line only like

<obj  id=\"pluvi\" border=\"0\" clsid=\"clsid:VI\" style=\"opacity: 0.0; background-color: #000000; width: 0px; height: 0px;\"></obj>"

so i use gsub method to remove new line character like

line = line.gsub(" *\n+", ' ')
line = line.gsub(" *\t+", ' ')

but again after this i am not able to get content in 1 line.

to see the content present in file i used below method and got ouptput like this in irb

 text = File.open('G:/index.html').read

=> "<obj  id=\"pluvi\" border=\"0\"\n\tclsid=\"clsid:VI\"\n\tstyle=\"opacity: 0.0; background-color: #000000; width: 0px; height: 0px;\"></obj>"

So how can i solve above problem?

Answer 1

You can remove all the empty/white space in the line using strip

completeLine = ""
file.each_line do |line|
  completeLine = completeLine + line.strip
end

Answer 2

chomp will remove \\n, \\r, and \\r\\n, if $/ has not been changed from the default Ruby record separator:)

completeLine = ""
file.each_line do |line|
  completeLine = completeLine + line.chomp
end
