## Task

In this exercise your goal is create a package that makes it easy to parse an HTML file and extract all of the links (`...` tags). For each extracted link you should return a data structure that includes both the `href`, as well as the text inside the link. Any HTML inside of the link can be 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.

```html



  Something in a span

  Text not in a span

  Bold text!



```

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

```go

Link{

  Href: "/dog",

  Text: "Something in a span Text not in a span Bold text!",

}

```

### Notes

**1. Use the x/net/html package**

I recommend checking out the [x/net/html](https://godoc.org/golang.org/x/net/html) package for this task, which you will need to `go get`. It is provided by the Go team, but isn't included in the standard library. This makes it a little easier to parse HTML files.

**2. Ignore nested links**

You can ignore any links nested inside of another link. Eg with following HTML:

```html



  Something here nested dog link

```

It is okay if your code returns only the outside link.

**3. Get something working before focusing on edge-cases**

Don't worry about having perfect code. Chances are there will be a lot of edge cases here that will be kinda tricky to handle. Just try to cover the most basic use cases first and then improve on that.

**4. A few HTML examples have been provided**

I created a few simpler HTML files and included them in this repo to help with testing. They won't cover all potential use cases, but should help you start testing out your code.

**5. The fourth example will help you remove comments from your link text**

Chances are your first version will include the text from comments inside a link tag. Mine did.
