Question

How I can convert all value of element and attributes of xml to Map of string ?
Is there some library which can do this ? I found library xStream but I dont know how to configure it.

Answer 1

I just wanna this:

public static Map<String, String> convertNodesFromXml(String xml) throws Exception {

    InputStream is = new ByteArrayInputStream(xml.getBytes());
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    dbf.setNamespaceAware(true);
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document document = db.parse(is);
    return createMap(document.getDocumentElement());
}

public static Map<String, String> createMap(Node node) {
    Map<String, String> map = new HashMap<String, String>();
    NodeList nodeList = node.getChildNodes();
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentNode = nodeList.item(i);
        if (currentNode.hasAttributes()) {
            for (int j = 0; j < currentNode.getAttributes().getLength(); j++) {
                Node item = currentNode.getAttributes().item(i);
                map.put(item.getNodeName(), item.getTextContent());
            }
        }
        if (node.getFirstChild() != null && node.getFirstChild().getNodeType() == Node.ELEMENT_NODE) {
            map.putAll(createMap(currentNode));
        } else if (node.getFirstChild().getNodeType() == Node.TEXT_NODE) {
            map.put(node.getLocalName(), node.getTextContent());
        }
    }
    return map;
}
