            Element accountInfoElement = (Element) accountInfo;

            balance = accountInfoElement.getElementsByTagName("Balance").item(0).getTextContent();
        }

Heres 2 ways you can do it:

Node accountInfo = document.getElementsByTagName("AccountInfo").item(0);
NodeList children = accountInfo.getChildNodes();

or you can do

XPath xPath = XPathFactory.newInstance().newXPath();
NodeList children = (NodeList) xPath.evaluate("//AccountInfo/*", document.getDocumentElement(), XPathConstants.NODESET);

Once you have your NodeList you can loop through them.

for(int i=0;i<children.getLength();i++) {
    if(children.item(i).getNodeType() == Node.ELEMENT_NODE) {
        Element elem = (Element)children.item(i);
        // If your document is namespace aware use localName
        String localName = elem.getLocalName();
        // Tag name returns the localName and the namespace prefix
        String tagName= elem.getTagName();
        // do stuff with the children
    }
}
