How to get child nodes with ELEMENT_NODE type only

Question

I'm parsing a xml document using java DOM and I need to get every single node for doing something.

I have this code:

public void analyze_file(Node node){
        if(node.getNodeType() != Node.DOCUMENT_NODE){
            //do something
        }
        NodeList list = node.getChildNodes();
        for(int i=0; i<list.getLength(); i++){
            if(list.item(i).getNodeType() == Node.ELEMENT_NODE){
                analyze_file(list.item(i));
            }
        }
}

The problem is that, my xml file is very large ( > 30000 lines), and the code above needs too much time for checking whether a node is of ELEMENT_NODE type or not. I see that if the program stopped after it reached the last ELEMENT_NODE node, the execution time would be very small.

Is there any way to get all child nodes whose type is ELEMENT_NODE only?

For example: NodeList list = node.getElementChildNodes();

Thanks for any help!

node.getElementsByTagName("*")

From JavaDoc: Returns a NodeList of all descendant Elements with a given tag name, in document order. Name - The name of the tag to match on. The special value "*" matches all tags.
