Parse xml without tagname

Question

I have a xml file

<Response>
<StatusCode>0</StatusCode>
<StatusDetail>OK</StatusDetail>
<AccountInfo> 
    <element1>value</element1>
    <element2>value</element2>
    <element3>value</element2>
    <elementN>value</elementN>   
</AccountInfo>
</Response>

And I want parse my elements in AccountInfo, but I dont know elements tag names.

Now Im using and have this code for tests, but in future I will recieve more elemenets in AccountInfo and I dont know how many or there names

String name="";
String balance="";
 Node accountInfo = document.getElementsByTagName("AccountInfo").item(0);

        if (accountInfo.getNodeType() == Node.ELEMENT_NODE){
            Element accountInfoElement = (Element) accountInfo;
            name = accountInfoElement.getElementsByTagName("Name").item(0).getTextContent();
            balance = accountInfoElement.getElementsByTagName("Balance").item(0).getTextContent();
        }

How do you want to extract information in a meaningful way if you don't know what tags there can be (and what they signify)? — Thilo, Jun 27 '14 at 08:05
Are you sure you would like that dynamically? If you have n number of different variables parsed in a dynamic way, it could be hard to use them (for instance if you use some algorithm to calculate some value). The values would (more or less) be represented in a list. The usual way to do it is have one implementation for a specific set of input. Or would you just like to dump the values to a database? — Pphoenix, Jun 27 '14 at 08:06

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
    }
}
