HTML Link Parser

For each extracted link this program returns a data structure Link which includes both the href, as well as the text inside the link. Any HTML inside of the link is stripped out, along with any extra whitespace including newlines, back-to-back spaces, etc.

Links will be nested in different HTML elements, and it is very possible that you will have to deal with HTML similar to code below.

<a href="/dog">
  <span>Something in a span</span>
  Text not in a span
  <b>Bold text!</b>
</a>

In situations like these, we want to get output that looks roughly like:

Link{
  Href: "/dog",
  Text: "Something in a span Text not in a span Bold text!",
}

Usage

go run main.go <filename>

Response would be something like this:

[{/other-page A link to another page} {/second-page A link to second page}]
