Web scraping (web harvesting or web data extraction) is data scraping used for extracting data from websites.

Web scraping software may access the World Wide Web directly using the Hypertext Transfer Protocol, or through a web browser.

While web scraping can be done manually by a software user, the term typically refers to automated processes implemented using a bot or web crawler.

It is a form of copying, in which specific data is gathered and copied from the web, typically into a central local database or spreadsheet, for later retrieval or analysis.

Beautiful Soup is a Python package for parsing HTML and XML documents (including having malformed markup, i.e. non-closed tags, so named after tag soup).

It creates a parse tree for parsed pages that can be used to extract data from HTML, which is useful for web scraping.

The following tables list notable software packages that are nominal IDEs; standalone tools such as source code editors and GUI builders are not included.

These IDEs are listed in alphabetical order of the supported language.

In linguistics, syntax is the set of rules, principles, and processes that govern the structure of sentences in a given language, specifically word order.

The term syntax is also used to refer to the study of such principles and processes.

The goal of many syntacticians is to discover the syntactic rules common to all languages.

A scripting or script language is a programming language that supports scripts; programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator.

Scripting languages are often interpreted (rather than compiled).

Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs.

Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games.

A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting languages are also sometimes referred to as very high-level programming languages, as they operate at a high level of abstraction, or as control languages, particularly for job control languages on mainframes.
