How To Install libhtmlcxx3v5 on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libhtmlcxx3v5 on Ubuntu 18.04.
What is libhtmlcxx3v5
libhtmlcxx3v5 is:
htmlcxx is a simple non-validating CSS1 and HTML parser for C++. Although there are several other html parsers available, htmlcxx has some characteristics that make it unique:
- STL like navigation of DOM tree, using excellent tree.hh library from Kasper Peeters
- It is possible to reproduce exactly, character by character, the original document from the parse tree
- Bundled CSS parser
- Optional parsing of attributes
- C++ code that looks like C++ (not so true anymore)
- Offsets of tags/elements in the original document are stored in the nodes of the DOM tree
The parsing politics of htmlcxx were created trying to mimic Mozilla Firefox (http://www.mozilla.org) behavior. So you should expect parse trees similar to those create by Firefox. However, differently from Firefox, htmlcxx does not insert non-existent stuff in your html. Therefore, serializing the DOM tree gives exactly the same bytes contained in the original HTML document.
