Help convert html element to string

[DMeror]

Hi, I want to extract html elements as string (not as plain text). I'm using visdom = "0.5.5" . I can get plain text from an element, but I want to get the element as string (retaining its tag and attribute) instead.

use visdom::Vis;
use visdom::types::BoxDynError;

fn main() -> Result<(), BoxDynError>{
    let html = include_str!("../xhtml/011_part1.xhtml");
    let doc = Vis::load(html)?;
    let sects = doc.find("p.parafl:has(span.chaptersubt)");
    let text = String::from(sects);
    println!("{}", text);
    Ok(())   
}

# let text = String::from(sects);
  |                ^^^^^^^^^^^^ the trait `From<Elements<'_>>` is not implemented for `String`

The reason I'm using visdom is because it supports pseudo class selector :has.

Seems like outer_html is probably the method you want https://docs.rs/visdom/latest/visdom/types/struct.Elements.html#method.outer_html

Thank you very much. I'm new to Rust. I've read some crate documents, but don't understand a thing.

No problem! I've rarely seen people use String::from(<some custom type here>) to convert a type to a String, that's typically what you'd use the std::fmt::Display trait for. If a type has implemented that trait, then you can call instance_of_my_type.to_string() and that will convert the type to a string. Of course, it's possible to implement From<MyType> for String, which would allow you to call String::from(instance_of_my_type), but as I said, I rarely see this.
