TagSoup - HTML/XML parser for Haskell

•    Haskell

---

TagSoup is a library for parsing HTML/XML. It supports the HTML 5 specification, and can be used to parse either well-formed XML, or unstructured and malformed HTML from the web. The library also provides useful functions to extract information from an HTML document, making it ideal for screen-scraping.

Nokogiri - HTML, XML, SAX, and Reader parser with XPath and CSS selector support

•    Ruby

---

Nokogiri (?) is an HTML, XML, SAX, DOM parser. Among Nokogiri's many features is the ability to search documents via XPath or CSS3 selectors, XML/HTML builder, XSLT transformer. Nokogiri parses and searches XML/HTML using native libraries (either C or Java, depending on your Ruby), which means it's fast and standards-compliant.

posthtml - PostHTML is a tool to transform HTML/XML with JS plugins

•    Javascript

---

PostHTML is a tool for transforming HTML/XML with JS plugins. PostHTML itself is very small. It includes only a HTML parser, a HTML node tree API and a node tree stringifier. All HTML transformations are made by plugins. And these plugins are just small plain JS functions, which receive a HTML node tree, transform it, and return a modified tree.

TagSoup - SAX-compliant parser in Java

•    Java

---

TagSoup, a SAX-compliant parser written in Java that, instead of parsing well-formed or valid XML, parses HTML as it is found in the wild: poor, nasty and brutish, though quite often far from short. TagSoup is designed for people who have to process this stuff using some semblance of a rational application design. TagSoup also includes a command-line processor that reads HTML files and can generate either clean HTML or well-formed XML that is a close approximation to XHTML.

node-htmlparser - Forgiving HTML/XML/RSS Parser in JS for *both* Node and Browsers

•    Javascript

---

#NodeHtmlParser A forgiving HTML/XML/RSS parser written in JS for both the browser and NodeJS (yes, despite the name it works just fine in any modern browser). The parser can handle streams (chunked data) and supports custom handlers for writing custom DOMs/output.

oga - Moved to https://gitlab.com/yorickpeterse/oga

•    Ruby

---

NOTE: my spare time is limited which means I am unable to dedicate a lot of time on Oga. If you're interested in contributing to FOSS, please take a look at the open issues and submit a pull request to address them where possible. Oga is an XML/HTML parser written in Ruby. It provides an easy to use API for parsing, modifying and querying documents (using XPath expressions). Oga does not require system libraries such as libxml, making it easier and faster to install on various platforms. To achieve better performance Oga uses a small, native extension (C for MRI/Rubinius, Java for JRuby).

Fuzi - A fast & lightweight XML & HTML parser in Swift with XPath & CSS support

•    Swift

---

Fuzi is based on a Swift port of Mattt Thompson's Ono(斧), using most of its low level implementaions with moderate class & interface redesign following standard Swift conventions, along with several bug fixes. Fuzi(斧子) means "axe", in homage to Ono(斧), which in turn is inspired by Nokogiri (鋸), which means "saw".

Neko HTML Parser - simple HTML scanner

•    Java

---

NekoHTML is a simple HTML scanner and tag balancer that enables application programmers to parse HTML documents and access the information using standard XML interfaces. The parser can scan HTML files and fix up many common mistakes that human (and computer) authors make in writing HTML documents. NekoHTML adds missing parent elements. Automatically closes elements with optional end tags and can handle mismatched inline element tags.

Beautiful Soup - Python HTML/XML parser

•    Python

---

Beautiful Soup is a Python HTML/XML parser designed for quick turnaround projects like screen-scraping. Beautiful Soup parses anything you give it, and does the tree traversal stuff for you. You can tell it "Find all the links", or "Find all the links of class externalLink", or "Find all the links whose urls match "foo.com", or "Find the table heading that's got bold text, then give me that text."

Hpricot - HTML parser for Ruby

•    C

---

Hpricot is a fast, flexible HTML parser. Hpricot can be handy for reading broken XML files, since many of the same techniques can be used. If a quote is missing, Hpricot tries to figure it out. If tags overlap, Hpricot works on sorting them out.

HtmlCleaner - HTML parser in Java

•    Java

---

HtmlCleaner is HTML parser written in Java. HTML found on Web is usually dirty, ill-formed and unsuitable for further processing. HtmlCleaner reorders individual elements and produces well-formed XML. By default, it follows similar rules that the most of web browsers use in order to create Document Object Model. However, user may provide custom tag and rule set for tag filtering and balancing.

AngleSharp - The ultimate angle brackets parser library parsing HTML5, MathML, SVG and CSS to construct a DOM based on the official W3C specifications

•    CSharp

---

AngleSharp is a .NET library that gives you the ability to parse angle bracket based hyper-texts like HTML, SVG, and MathML. XML without validation is also supported by the library. An important aspect of AngleSharp is that CSS can also be parsed. The included parser is built upon the official W3C specification. This produces a perfectly portable HTML5 DOM representation of the given source code and ensures compatibility with results in evergreen browsers. Also standard DOM features such as querySelector or querySelectorAll work for tree traversal.

xml-stream - XML stream parser based on Expat. Made for Node.

•    Javascript

---

XmlStream is a Node.js XML stream parser and editor, based on node-expat (libexpat SAX-like parser binding). When working with large XML files, it is probably a bad idea to use an XML to JavaScript object converter, or simply buffer the whole document in memory. Then again, a typical SAX parser might be too low-level for some tasks (and often a real pain).
