Emacs Lisp: mark HTML on the web page and convert it quickly to Markdown format

Emacs Lisp: mark HTML on the web page and convert it quickly to Markdown format. This function needs your own customizations. You would mark the HTML on a web page within your browser. Then you run the Emacs Lisp function and the clipboard is converted into Markdown file. The file is opened for further editing and saved for future just as a note.

Customize the function to your own needs, for example, you should change the directory where files are stored. And you must have shell commands xclip and pandoc .

You would need to mark the parts of the HTML page within your browser such as Iceweasel or IceCat. Then you run this function in Emacs Lisp. It uses `pandoc` and `xclip` shell commands to write Markdown file. Finally it opens file for editing."
