How to define a ruby array that contains a backslash("\") character?


How to define a ruby array that contains a backslash("\") character?

I wish this helpful for you There are some characters which are special and need to be escaped. Like when you define a string
code :
str = " this is test string \
and this contains multiline data \
do you understand the backslash meaning here \
it is being used to denote the continuation of line"
char = "\\"
char.length # => 1

it fixes the issue The question still isn't clear: if you write the XML string (before you try to clean it) to the console, do you see exactly what you posted above, with all those \" and \n sequences? Does the displayed string start and end with a quotation mark? If so, you probably want to remove the opening and closing quotation marks and all the backslashes, and if any backslash is followed by an 'n', you want to remove that as well. Here's some code to demonstrate:
code :
static void Main(string[] args)
{
  string dirtyXml = @"""<?xml version=\""1.0\"" encoding=\""UTF-8\""?>\n\n<ISBNdb server_time=\""2010-01-28T11:31:08Z\"">\n<BookList total_results=\""1\"" page_size=\""10\"" page_number=\""1\"" shown_results=\""1\"">\n<BookData book_id=\""quantitative_techniques\"" isbn=\""0826458548\"" isbn13=\""9780826458544\"">\n<Title>Quantitative techniques</Title>\n<TitleLong></TitleLong>\n<AuthorsText>Terry Lucey</AuthorsText>\n<PublisherText publisher_id=\""continuum\"">London : Continuum, 2002.</PublisherText>\n</BookData>\n</BookList>\n</ISBNdb>\n""";
  Console.WriteLine(dirtyXml);
  Console.WriteLine();
  Console.WriteLine(Regex.Replace(dirtyXml, @"^""|""$|\\n?", ""));
}

like below fixes the issue There is no such method in popular libraries, but there is how this could be implemented
code :
class Module
  def alias_opposite(a, b)
    define_method(a) { !self.send(b) }
  end
end
class A < Struct.new(:happiness)
  def happy?
    happiness > 3
  end

  alias_opposite :sad?, :happy?
end

p A.new(1).sad? # => true
p A.new(5).sad? # => false

This might help you
But, I think the number of spaces is somehow defined in certain algorithm.

fixed the issue. Will look into that further As an alternative to what Oz123 already wrote, you might want to use string formatting:
In Ruby on Rails I need to define this field "estado " automatically like "Inactivo", when I create
