we use context free grammer in compiler consctrtion to cheack the validati of input in parsing.

In layman's terms, you're missing a brace to close your class definition.
Extensive MarkUp languageXML parsing is when you convert an XML document into an XML DOM object - which can then be manipulated with a JavaScript.

Separating the analysis phase into lexical analysis and parsing helps to break down the process of interpreting the structure of a source code into more manageable steps. Lexical analysis focuses on breaking the input into tokens, which are the smallest meaningful units, while parsing constructs a parse tree or syntax tree to represent the grammatical structure of the code. This separation allows for easier maintenance, testing, and implementation of new features in the compiler or interpreter.

Lex and Yacc are two tools that are used to implement the first stages of compilation: tokenization (lexical analysis) and parsing. Free and Open Source versions of these tools are available called Flex and Bison.
Top-down parsing starts with the input and works its way down to the start symbol, while bottom-up parsing starts with the input and works its way up to the start symbol. Top-down parsing uses predictive parsing techniques, such as LL and recursive descent, while bottom-up parsing uses shift-reduce or LR parsing algorithms.

Stacks are not only the preferred data structure for bottom up parsing, they are the only data structure suitable for bottom up parsing. Bottom-up parsing is usually referred to as depth-first search. Top-down parsing is referred to as breadth-first search. The two are exactly the same in terms of implementation, the difference is only in the structure used to store information collated from the previous iterations. With top-down parsing you use a queue, pushing to the back and popping from the front. With bottom-up parsing you use a stack, pushing to and popping from the back.
