An HTML parser is a library designed to parse HTML documents. Usually, it can also parse XML. In other words, HTML parsers process the HTML code and convert it into a structured data format that can easily be navigated and manipulated. What they produce is an easier-to-explore representation of the [DOM](https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model) associated with the HTML page. HTML parsers typically take local files, URLs, or raw HTML strings as input. Then, they start analyzing the HTML code character by character, identifying different elements such as tags, attributes, and content. As they parse the XML/HTML document, they build a tree-like structure that contains the hierarchical representation of the HTML document. One of the most important use case for an HTML parsing library is [web scraping](/blog/how-tos/what-is-web-scraping). For example, assume that you want to retrieve product information from an online shopping website. You can use an HTTP client to retrieve the HTML document associated with the target page. Next, feed that HTML content to the HTML parser. Use its API to navigate the parse tree to locate and extract relevant information such as product names, prices, and more. To target specific HTML elements on the DOM, HTML parsers generally support node selector strategies based on[ CSS selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_selectors) or [XPath expressions](https://developer.mozilla.org/en-US/docs/Web/XPath). Given an HTML node, they usually provide methods to extract its text content or read its attribute values. ## Elements to Consider When Evaluating the Best HTML Parsing Libraries Here are the list of the most important aspects to consider when comparing the best HTML parsers available: - **Pros and cons**: The main benefits and drawbacks of the library. - **Programming language**: The programming language the package is written in. - **GitHub stars**: The number of stars the repository associated with the HTML parsing library has on GitHub. - **CSS selector support**: Whether the HTML parser comes with built-in support for CSS selectors. - **XPath support**: Whether the library has built-in support for XPath expressions. Let’s now apply these criteria to evaluate the best HTML parsers in the IT world! ## Top 7 HTML Parsers Time to explore the best HTML parsing libraries. ## **1. jsoup** [jsoup](https://github.com/jhy/jsoup) is a robust Java library designed for parsing HTML documents. On top of that, it comes with a complete API for HTML manipulation and data extraction via CSS selectors or XPath expressions. As an all-in-one scraping library, it also provides an easy-to-use method for HTML fetching from a URL. Become an expert with our [jsoup web scraping guide](/blog/how-tos/web-scraping-with-jsoup). **Pros**: - Implements the [WHATWG HTML](https://html.spec.whatwg.org/multipage/) specification - HTTP client included in the library - Vast API with a lot of methods and utilities - Full [API documentation](https://jsoup.org/apidocs/) available online **Cons**: - Not the fastest HTML parser **Programming language**: Java **GitHub stars**: 10.5k **CSS selector support**: Yes **XPath support**: Yes ## **2. Nokogiri** [Nokogiri](https://github.com/sparklemotion/nokogiri) provides an easy-to-understand API for reading, writing, modifying, and querying XML and HTML documents in Ruby. It is fast and standards-compliant, which makes it not the best HTML parsers. Under the hood, it relies on native parsers like libxml2, libgumbo, and xerces. **Pros**: - Secure by default as it treats all documents as untrusted - CSS3 selectors, with some jQuery-like extensions - Full [API documentation](https://nokogiri.org/rdoc/index.html) - Community-maintained [cheat sheet](https://github.com/sparklemotion/nokogiri/wiki/Cheat-sheet) **Cons**: - Not the most used HTML parsing library **Programming language**: Ruby **GitHub stars**: 6.1k **CSS selector support**: Yes **XPath support**: Yes ## **3. Beautiful Soup** [Beautiful Soup](https://launchpad.net/beautifulsoup) is a Python library for parsing HTML and XML documents and files to extract data from them. It provides intuitive ways to navigate, search, and modify the parse tree. It supports several underlying parsers and has a number of advanced features, such as the HTML code prettifier. Find out more in our tutorial on [Beautiful Soup web scraping](/blog/how-tos/beautiful-soup-web-scraping). **Pros**: - Different underlying parsers - One of the most widely used HTML parsing libraries - HTML and XML code formatting capabilities - Fast releases **Cons**: - No API documentation - No native support for XPath **Programming language**: Python **GitHub stars**: — (not on GitHub) **CSS selector support**: Yes **XPath support**: Not natively, but possible with the [lxml](https://lxml.de/) package ## **4. Cheerio** [Cheerio](https://github.com/cheeriojs/cheerio) provides a comprehensive jQuery-inspired API for parsing HTML in JavaScript. If you are already familiar with jQuery, you can get the best of this library right out of the box. Cheerio has made performance a top priority, working with a very simple and consistent DOM representation model. Learn more in our step-by-step tutorial on [Cheerio web scraping](/blog/how-tos/cheerio-npm-web-scraping). **Pros**: - jQuery-like syntax - Over [7 million weekly downloads on npm](https://www.npmjs.com/package/cheerio) - Great performance **Cons**: - Still in beta - No XPath native support **Programming language**: JavaScript (Node.js) **GitHub stars**: 27.6k **CSS selector support**: Yes **XPath support**: No ## **5. Html Agility Pack** [Html Agility Pack](/blog/how-tos/web-scraping-with-c-sharp), also known as “HAP,” is an HTML parser written in C# to read and write HTML documents. It supports plain XPATH and [XSLT](https://developer.mozilla.org/en-US/docs/Web/XSLT), but not CSS selectors. Most developers consider it the go-to .NET library to parse “out of the web” HTML. While it is not the most popular, it is still one of the best HTML parsers. See the parser in action in our [Html Agility Pack scraping tutorial](/blog/how-tos/web-scraping-with-c-sharp). **Pros**: - Works with any .NET-compatible language - XSLT support - Frequent releases **Cons**: - Little documentation - No native support for CSS selectors **Programming language**: C# **GitHub stars**: 2.5k **CSS selector support**: Not natively, but possible via the [HtmlAgilityPack.CssSelector](https://github.com/hcesar/HtmlAgilityPack.CssSelector) extension **XPath support**: Yes ## **6. libxml2** [libxml2](https://gitlab.gnome.org/GNOME/libxml2/) is a C library originally developed as part of the [GNOME](https://www.gnome.org/) project to parse XML. Like most C libraries, it provides extremely high performance by working with low-level data structures. Here is why many other high-level HTML parsers use it behind the scenes. **Pros**: - Used by many other parsing libraries - Extreme performance **Cons**: - Complex API - Not for beginners - Limited to XPath **Programming language**: C **GitHub stars**: — (not on GitHub) **CSS selector support**: No **XPath support**: Yes ## **7. PHPHtmlParser** [PHPHtmlParser](https://github.com/paquettg/php-html-parser) is a simple and flexible HTML parser written in PHP to select nodes in the DOM using CSS selectors. Its main goal is to assist in the development of PHP scraping scripts. It works well also with non-standard and broken HTML. **Pros**: - Can parse broken HTML - Complete API for web scraping **Cons**: - Not actively maintained - No documentation - No XPath native support **Programming language**: PHP **GitHub stars**: 2.3k **CSS selector support**: Yes **XPath support**: No ## Best HTML Parser: Summary Table Compare the best HTML parsers with the summary table below: **HTML Parser****Programming Language****GitHub stars****CSS Selector****XPath****jsoup**Java10.5k✅✅**Nokogiri**Ruby6.1k✅✅**Beautiful Soup**Python—✅Possible via an extra dependency**Cheerio**JavaScript27.6k✅❌**Html Agility Pack**C#2.5kPossible via an extension✅**libxml2**C—❌✅**PHPHtmlParser**PHP2.3k✅❌Great!
