// allocates 1024 bytes internally
let mut reader = xml::Reader::new(&mut reader, xml.len(), 1024)?;
loop {
    match reader.next_event()? {
        xml::Event::StartElement { name, attrs } => {
            println!("Start element: {name} with attributes: {attrs:?}");
        }
        xml::Event::EndElement { name } => {
            println!("End element: {name}");
        }
