@Laymer ,
Will certainly have a look at HTML parsing library, although using GitHub - philss/floki: Floki is a simple HTML parser that enables search for nodes using CSS selectors. · GitHub and had a use case where javascript needs to parsed for which i created a issue .
For json encoding and decoding using poison
it will good to know how to do safe handling of web content going through specification will certainly help to get the idea.
Thanks for your time and providing valuable feedback.
