    element h1{"Product catalog"}
    element ul{let $file := xdmp:document-get("d:\users\tdu\xquery\cataloge.xml")
                for $prod in ($file/catalog/product)
                return element li {("number:",data($prod/number),", name:",data($prod/name))}
    }
}

xquery version "1.0-ml";
element html{
    element h1{"Product catalog"}
    element ul{let $file := xdmp:document-get("d:\users\tdu\xquery\cataloge.xml")
