This example creates a div element with a http://www.w3.org/1999/xhtml namespace. The namespace is used to identify which type of XML this tag node belongs to.
Valid namespace:
http://www.w3.org/1999/xhtml for HTML
http://www.w3.org/2000/svg for SVG
pub fn document_create_element_ns()
{
let window = web_sys::window().expect("global window does not exists");
let document = window.document().expect("expecting a document on window");
let body = document.body().expect("document expect to have have a body");
let val = document
.create_element_ns(Some("http://www.w3.org/1999/xhtml"),"div")
.unwrap();
val.set_inner_html("Hello World from create_element_ns.");
body.append_child(&val).unwrap();
}
pub fn create_element_ns(&self, namespace: Option<&str>,
qualified_name: &str)
-> Result<Element, JsValue>
