`html_parser` is a simple library for parsing an HTML document. Use `html_parser.as_list` to parse the document

as List of Elements. Use `html_parser.as_tree` to create a nested structure where Elements have children.

- `StartElement`: HTML opening tag, like `
`

- `EndElement`: HTML closing tag, like `
`

- `Content`: Non-HTML parts of the document inside tags (the "hello" in `
hello
`)

- `Attributes`: HTML attributes inside of a tag (`href` key and value in ``)


```sh

gleam add html_parser@1

```

```gleam

import html_parser

pub fn main() {

  "
Data!
"

  |> html_parser.as_list

  |> find_div

  |> io.debug

}


// find a starting div where class=data and the next element is Content

fn find_div(in: List(html_parser.Element)) -> String {

  case in {

    [] -> "Not found"

    [

      html_parser.StartElement("div", [html_parser.Attribute("class", "data")], _),

      html_parser.Content(contents),

      ..

    ] -> contents

    [_, ..tail] -> find_div(tail)

  }

}

```
