    Nokogiri

    Nokogiri

    Tool to work with XML and HTML from Ruby

    Nokogiri (鋸) makes it easy and painless to work with XML and HTML from Ruby. It provides a sensible, easy-to-understand API for reading, writing, modifying, and querying documents. It is fast and standards-compliant by relying on native parsers like libxml2 (C) and xerces (Java). Be secure-by-default by treating all documents as untrusted by default. Be a thin-as-reasonable layer on top of the underlying parsers, and don't attempt to fix behavioral differences between the parsers. "Native gems" contain pre-compiled libraries for a specific machine architecture. On supported platforms, this removes the need for compiling the C extension and the packaged libraries, or for system dependencies to exist. This results in much faster installation and more reliable installation, which as you probably know are the biggest headaches for Nokogiri users.

    Gumbo

    Gumbo

    An HTML5 parsing library in pure C99

    Gumbo is an implementation of the HTML5 parsing algorithm implemented as a pure C99 library with no outside dependencies. It's designed to serve as a building block for other tools and libraries such as linters, validators, templating languages, and refactoring and analysis tools. Gumbo gains some of this by virtue of being written in C, but it is not an important consideration for the intended use-case, and was not a major design factor. Gumbo is intentionally designed to turn an HTML document into a parse tree, and free that parse tree all at once. To install the python bindings, make sure that the C library is installed first, and then sudo python setup.py install from the root of the distro. This installs a 'gumbo' module; pydoc gumbo should tell you about it. Tested on over 2.5 billion pages from Google's index. Passes all html5lib tests, including the template tag.
