Best of Techopedia weekly. News and Special Offers occasional. Techopedia Explains Parser. What Does Parser Mean? Techopedia Explains Parser In order for the code written in human-readable form to be understood by a machine, it must be converted into machine language.

The overall process of parsing involves three stages: Lexical Analysis: A lexical analyzer is used to produce tokens from a stream of input string characters, which are broken into small components to form meaningful expressions. This is achieved as follows: Top-Down Parsing: Involves searching a parse tree to find the left-most derivations of an input stream by using a top-down expansion.

Parsers are widely used in the following technologies: Java and other programming languages. Interactive data language and object definition language. Database languages, such as SQL. Modeling languages, such as virtual reality modeling language. Scripting languages. What is parse tree example?

A parser from: to parse — analyze a string or text into logical syntactic components is a program that is usually part of a compiler. The compiler ensures that the code is correctly translated into a machine executable language. The task of the parser is, in this case, the decomposition and transformation of inputs into a usable format for further processing.

A string of instructions in a programming language is analyzed and then broken down into its individual components.
