Printing double-quotes to files in Ruby

Hi All,

I had a brilliant thought this morning, why not use ruby to generate some xml for me.

Was a great idea, but I have fallen flat on my face when it comes to adding " to my xml file.

I am trying to create this line: puts results_file.puts "<component timestamp="" name=""#{x}"" />"

But, my issue is that it is giving me:
<component timestamp= name=some_name.dll />

as you can probably tell, this doesnt look good. Could some kind soul let me know how to put the " char correctly into my output please?

Cheers

and I figured it out by using \" to include them in the file making my code look like:

puts results_file.puts "<component timestamp=\"\" name=\"#{x}\" />

Alternatively, you could enclose your string in %Q{}

Code:

#!/usr/bin/ruby

x = "hello"
f = File.open("file.txt", "w")
f.puts %Q{<component timestamp="" name="#{x}" />}
f.close()

Note that %q won't substitute #{x} and will leave it in literally, whereas %Q will interpolate the variable.
