// 2.1, each lexeme is a non-terminal, which can be further evaluated/derived until it becomes a terminal. when it has been exhaustively derived, we will consider that as a token
// For example for the simple xml <course name="automata"/>,
// when we read the "<" opening tag, that's already one token because sigma will always point to an opening tag,
// when we read the "c" in "course", we will keep reading "o", "u", "r", "s", "e" until the next space, and treat the "course" string as one token.
// when we read the "name" that's a token
// when we read "=", that's a token
// when we read the double quotes (") that's a token"
// etc.
// 3. When we are traversing the string and figuring out the tokens, we look at a dictionary that stores key-value pairs for each token and its terminator. a
// 3.1 For example, for the "<" token, the dictionary can contain the "/>" terminator for self-closing tags
// 3.2 For the double quotes, the dictionary can contain double quotes to enclose attribute values
// [SYNTAX/PARSER] 4. As we are identifying tokens, push it to a stack, and if we encounter a terminator token, we will pop the token in the top of stack which the terminator terminates.
// 4.1 we are guaranteed that the item at the top of the stack will always terminate first if it is a valid XML. if not, then the xml is invalid. If the stack becomes empty and there are no more tokens, then the XML is accepted
