Solutions to htmlcxx: command not found

How To Fix htmlcxx: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu htmlcxx is provided by libhtmlcxx-dev package.

libhtmlcxx-dev 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.

This package contains files required for developing software that makes use of htmlcxx.

To fix this problem, we can install more using the command below.

sudo apt-get -y install libhtmlcxx-dev

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install libhtmlcxx-dev.

sudo apt -y install libhtmlcxx-dev

Or if you have aptitude installed you can use the following command.

sudo aptitude install libhtmlcxx-dev
