删除Ruby中的换行符

Question

Is there a way to write a very long xml request in multiple lines instead of just one? When I write it in multiple lines, the string is not accepted because of the newlines inserted. How can I add newlines in my text editor with adding the newlines in the actual program? I am using sublime.

Ruby

str = "this is \n multi-line \n text \n\n"
puts str 
# this is
# multi-line
# text

Use gsub! to modify the string

str.gsub!("\n","") 
puts str # this is  multi-line  text

Rails

Use squish to remove all unnecessary white space

str = "this is \nmulti-line \n text \n\n"
puts str.squish # this is multi-line text
