# html_parser
[](https://hex.pm/packages/html_parser)
[](https://hexdocs.pm/html_parser/)
`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)
}
}
```
