HTMLCSS is a lightweight HTML/CSS parser written in C that allows applications to prepare a HTML document for rendering or conversion. HTMLCSS is extremely portable and only requires a C99 compiler like GCC, Clang, Visual C, etc. HTMLCSS is also extremely memory efficient, utilizing a shared string pool and smart CSS cache to minimize the size of a HTML document in memory.
I'm providing HTMLCSS as open source under the Apache License Version 2.0 with exceptions for use with GPL2/LGPL2 applications which allows you do pretty much do whatever you like with it. Please do provide feedback and report bugs to the Github project page so that everyone can benefit.
- HTML 5 markup parser
- CSS 3 stylesheet parser
- OFC/OFF/TTC/TTF font file parser (metadata and metrics only)
- GIF/JPG/PNG image file parser (metadata only)
- Functions to calculate CSS properties for a given node in a HTML document
- Functions to extract HTML "runs" consisting of CSS properties, content strings, and image references that can be rendered directly, including the :before and :after content from a stylesheet
You'll need a C99 compiler like GCC, Clang, or Visual C, along with a POSIX-
make to build the library and unit test program.
make install to install the library and header files under
To install in a different location, specify the "prefix" variable, e.g.:
make install prefix=/some/other/directory
See the file DOCUMENTATION.md for documentation on using the library.
