pub struct Selector { /* private fields */ }

Simple query selector

Implementations

impl Selector

pub fn from(selector: &str) -> Self

The selector only supports type selector, ID selector and class selector.

For example, div#app, span would be ok, but .container > div, #app * would get unexpected results.

use html_query_parser::Selector;
 
// Ok: Simple tag, class and ID selectors.
let selector = Selector::from("span");
let selector = Selector::from(".class");
let selector = Selector::from("#id");
 
// Ok: Mixed selector
let selector = Selector::from("div#app");
let selector = Selector::from("span.info#first");
 
// Disallowed
let selector = Selector::from("div span");
let selector = Selector::from("a[target=_blank]");

pub fn matches(&self, element: &Element) -> bool

Check if the element matches the selector.

use html_query_parser::{Node, Element, Selector, Htmlifiable};
 
let element: Element = Element::new(
    "div",
    vec![("id", "app")],
    vec![Node::Text("Hello World!".to_string())],
);
 
let selector = Selector::from("div#app");
 
assert_eq!(selector.matches(&element), true);
