Parsing XML Escape Charcters

Here is some C# code i've used in the past to make any piece of text XML safe, and vice-versa. The logic applies across all languages. Remember to escape & first!

private string outputParseFields(string field)

{

    // Escape illegal chars. (escape '&' first!)

    field = field.Replace("&", "&");

    field = field.Replace("<", "<");

    field = field.Replace(">", ">");

    field = field.Replace("'", "'");

    field = field.Replace("\"", """);

    return (field);

}

private string inputParseFields(string field)

{

    // Escape illegal chars. (escape '&' first!)

    field = field.Replace("&", "&");

    field = field.Replace("<", "<");

    field = field.Replace(">", ">");

    field = field.Replace("'", "'");

    field = field.Replace(""", "\"");

    return (field);

}
