xml解析

方法一：

String s\_xml1 = "" +
    "lalalalal" +
    "1234" +
    "";

try {
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(s\_xml1)));
Element element = document.getDocumentElement();
NodeList childNodes = element.getChildNodes();
if (childNodes != null) {
    for (int i = 0; i < childNodes.getLength(); i++) {
        Node item = childNodes.item(i);
        String name = item.getNodeName();
        String nodeValue = item.getNodeValue();
        String textContent = item.getTextContent();
        Log.i("xx-----", name + "---" + nodeValue + "---" + textContent);
    }
}
} catch (Exception e) {
e.printStackTrace();
}

方法二：

public void s() {
    //创建一个DocumentBuilderFactory的对象
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    //创建一个DocumentBuilder的对象
    String xmlStr = "
