What is Parser?
It is a parser that breaks complex data or code into meaningful pieces that the computer can process step by step.
Overview
A parser takes a chunk of text or data and transforms it into a structure that the program can logically understand. For example, it works like an interpreter that allows the computer to understand a plain line of code you write as 'there is a variable here, an operation is being performed here'. It creates a tree structure by dividing the data into pieces.
How it works
It takes raw data as input, scans this data according to the rules of the language or format, and ultimately produces a data model or tree structure. If there is a typo in the data, the parser will notice it immediately.
Where it is used
It is used in compilers to read HTML in web browsers and in any software that processes data formats (JSON, XML).
Commonly confused with
It can be confused with Document Parsing; However, parser is a more general concept and is used for all kinds of data structures.
Frequently asked questions
What happens if the parser gives an error?
If the parser finds the data in a format it cannot understand, it gives a 'syntax error' and prevents the process from continuing.
