    </movie>

    <movie id="1111">
        <title>Interstellar</title>
        <genre>Science Fiction</genre>
        <duration>180 mins</duration>
    </movie>

    **<movie id="2222">
        <title>test</title>
        <genre>test</genre>
        <duration>test</duration>
    </movie>**

</movies>

i try to use

NodeList nodes = doc.getElementsByTagName("movie");
for (int temp = 0; temp < nodes.getLength(); temp++){
Element element = (Element) doc.getElementsByTagName("movie").item(temp+1);
element.setAttribute("id", "2222");

to create and insert the attribute into last line but the

.getElementsByTagName("movie").item(temp+1);

only work with existing attribute().

It can be done, but you have the wrong approach. You must create the Element objects, and then create/set the Text in them. You will need to add the Element objects to the appropriate parent Element objects. And then you will have to serialize (write) the XML as characters to the file.

The whole think is actually somewhat tricky, with Java's native XML classes. There is a lot to be said for using a 3rd party library that wraps such things.
