    Your XML does not seem to be good.

    The first <node> element does not have name and type attributes.

    Ideally, while using XML you shouldn’t have the parent and child having same name. For example, the XML should be like :

    <books>
    <book id=1/>
    <book id=2/>
</books>

    Also, please consider properly formatting your XML for better readability.

    EDIT:

    There can be a check before retrieving any attribute as:

    if(childNodes.item(i).hasAttribute("name")) {
    // print the name
}
