### Parsing HTML and Getting Element by ID (Rust)

Source: https://github.com/y21/tl/blob/master/README.md

Demonstrates parsing an HTML string using `tl::parse` and retrieving an element by its ID using `get_element_by_id`. It then accesses the element's inner text.

```Rust
let dom = tl::parse(r#"<p id="text">Hello</p>"#, tl::ParserOptions::default()).unwrap();
let parser = dom.parser();
let element = dom.get_element_by_id("text")
  .expect("Failed to find element")
  .get(parser)
  .unwrap();

assert_eq!(element.inner_text(parser), "Hello");
```

### Mutating Anchor Tag href Attribute (Rust)

Source: https://github.com/y21/tl/blob/master/README.md

Demonstrates how to modify an attribute of a tag in the DOM. It finds an anchor tag using a query selector, gets a mutable reference to it, and updates its `href` attribute value.

```Rust
let input = r#"<div><a href="/about">About</a></div>"#;
let mut dom = tl::parse(input, tl::ParserOptions::default())
  .expect("HTML string too long");
  
let anchor = dom.query_selector("a[href]")
  .expect("Failed to parse query selector")
  .next()
  .expect("Failed to find anchor tag");

let parser_mut = dom.parser_mut();

let anchor = anchor.get_mut(parser_mut)
  .expect("Failed to resolve node")
  .as_tag_mut()
  .expect("Failed to cast Node to HTMLTag");

let attributes = anchor.attributes_mut();

attributes.get_mut("href")
  .flatten()
  .expect("Attribute not found or malformed")
  .set("http://localhost/about");

assert_eq!(attributes.get("href").flatten(), Some(&"http://localhost/about".into()));
```

### Finding Tag Using Query Selector (Rust)

Source: https://github.com/y21/tl/blob/master/README.md

Shows how to use the CSS query selector API (`query_selector`) to find a specific tag (an `<img>` tag with a `src` attribute) within the parsed DOM.

```Rust
let dom = tl::parse(r#"<div><img src="cool-image.png" /></div>"#, tl::ParserOptions::default()).unwrap();
let img = dom.query_selector("img[src]").unwrap().next();
    
assert!(img.is_some());
```

--------------------------------

### Adding tl Dependency (Cargo.toml)

Source: https://github.com/y21/tl/blob/master/README.md

Add the `tl` crate to your project's dependencies in the `Cargo.toml` file. You can specify the version or enable the `simd` feature for SIMD-accelerated parsing (requires a nightly compiler).

```TOML
[dependencies]
tl = "0.7.8"
# or, with explicit SIMD support
# (requires a nightly compiler!)
# tl = { version = "0.7.8", features = ["simd"] }
```

### Iterating Over Subnodes (Rust)

Source: https://github.com/y21/tl/blob/master/README.md

Illustrates how to iterate over the direct subnodes of the parsed HTML document using `dom.nodes().iter()` and find a specific tag (an `<img>` tag) by checking node type and tag name.

```Rust
let dom = tl::parse(r#"<div><img src="cool-image.png" /></div>"#, tl::ParserOptions::default()).unwrap();
let img = dom.nodes()
  .iter()
  .find(|node| {
    node.as_tag().map_or(false, |tag| tag.name() == "img")
  });
    
assert!(img.is_some());
```
