如何使用xml-rs获取xml中的属性值？

[dependencies]
xml-rs = "0.8"

use xml::reader::{EventReader, XmlEvent};
use std::io::BufReader;

let file = std::fs::File::open("path_to_xml_file.xml").unwrap();
let file = BufReader::new(file);
let parser = EventReader::new(file);

for event in parser {
    match event {
        Ok(XmlEvent::StartElement { name, attributes, .. }) => {
            if name.local_name == "element_name" {
                for attribute in attributes {
                    if attribute.name.local_name == "attribute_name" {
                        let attribute_value = attribute.value;
                        // 使用attribute_value进行后续操作
                    }
                }
            }
        }
        _ => {}
    }
}
