};

fn main() -> windows::Result<()> {
    let doc = XmlDocument::new()?;
    doc.load_xml("<html>hello world</html>")?;

    let root = doc.document_element()?;
    assert!(root.node_name()? == "html");
    assert!(root.inner_text()? == "hello world");

    unsafe {
        let event = CreateEventW(
            std::ptr::null_mut(),
            true.into(),
            false.into(),
            std::ptr::null(),
        );

        SetEvent(event).ok()?;
