how to remove the node? about scraper

I think the method you are looking for is called detach.

In any case, you cannot modify the tree while you iterating it (through the node references, via the selector), so I would suggest collecting the node identifiers and detaching them in a second pass:

let p_selector = Selector::parse("p").unwrap();
let ids = document.select(&p_selector).map(|p_node| p_node.id()).collect::<Vec<_>>();

for id in ids {
    document.tree.get_mut(id).unwrap().detach();
}
