### Manipulating the DOM

```rust
use html5ever::tree_builder::TreeSink;
use scraper::{Html, Selector};

let html = "<html><body>hello<p class=\"hello\">REMOVE ME</p></body></html>";
let selector = Selector::parse(".hello").unwrap();
let mut document = Html::parse_document(html);
let node_ids: Vec<_> = document.select(&selector).map(|x| x.id()).collect();
for id in node_ids {
document.remove_from_parent(&id);
}
assert_eq!(document.html(), "<html><head></head><body>hello</body></html>");
```
