Function rusthtml::tag_optimize

pub fn tag_optimize<'a>(content: Vec<HtmlTag<'a>>) -> Vec<HtmlTag<'a>>

A tag "completer" that fill in some missing tags allowed by html specification

Some html tags are allowed to be "inferred" in specific location; however, our parser does not allow this. Thus, this function will "fix" those tags.

This function is currently significantly incomplete compared to html specification.

let parsed = ElementContent::parse(tag_optimize(HtmlTag::parse(
       r#"<img abc>"#,
   )));
assert_eq!(parsed,
    Ok(vec![
        ElementContent::HtmlElement(Box::new(HtmlElement {
        name: "img",
        attributes: vec![("abc", None)],
        tag_state: ElementTagState::BothTag,
        content: Vec::new(),
    }))])
);
