TOP 7 PYTHON HTML MANIPULATION LIBRARIES

The top libraries for HTML manipulation using Python are listed below. It is more of a programmatic approach that lets us add, alter, or delete elements from a website document.  

Parsing examines and translates a code into an internal format that a runtime environment, such as the JavaScript engine found in browsers, can run. HTML is parsed by the browser and converted into a DOM tree. Tokenization and tree construction are involved in HTML parsing. Parsers are used when it is necessary to abstractly represent input data from source code as a data structure so that it can be checked for correct syntax. You can use objects to return and manipulate information about the HTML and CSS that comprise the document, such as getting a reference to an element in the DOM, changing its text content, applying new styles to it, creating new elements, and adding them as children to the current element, or even deleting it entirely.  

Here, we have listed a few libraries written in Python which help in HTML manipulation.   

lxml- 

• Suitable for processing and manipulating XML and HTML files as well. 
• It binds C libraries with python for handling files. 
• Great speed and is memory friendly. 

pyquery- 

• Allows to make queries on HTML and XML documents, much like jquery. 
• Uses lxml to increase the speed and efficiency of manipulation.  
• PyQuery class can be used to load an XML document from a string. 

html5lib-python- 

• HTML parsing software written entirely in Python. 
• It is intended to follow the WHATWG HTML specification.  
• Parser objects can be created explicitly to have more control over the parser. 

requests-html- 

• Intuitive and simple HTML parsing. 
• Automatic following of redirects. 
• Connection–pooling and cookie persistence. 
• CSS selectors and X-path selectors are like JQuery. 

parsel- 

• A python library to extract and remove data using Xpath and CSS selectors. 
• Combined with regular expressions occasionally.  
• Parsel-specific pseudo-elements are available to select text nodes. 

harser- 

• Easy manipulation of HTML documents and building X-path as well. 
• Can be easily pip installed. 
• A class Harser can be fed with an HTML document for parsing, and its methods can be used. 

AdvancedHTMLParser- 

• An HTML parser that produces a DOM node tree. 
• Provides common getElementsBy* functions for scraping, testing, modifying, and formatting. 
•  XPath is also supported.
