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);

}

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 = "<?xml version=\"1.0\" encoding=\"utf-8\"?>

";

StringReader sr = new StringReader(xmlStr);

InputSource is = new InputSource(sr);

HashMap hashMap = new HashMap();

try {

//创建DocumentBuilder对象

DocumentBuilder db = dbf.newDocumentBuilder();

//通过DocumentBuilder对象的parser方法加载books.xml文件到当前项目下

Document document = db.parse(is);

//获取所有book节点的集合

NodeList bookList = document.getElementsByTagName("title");

//通过nodelist的getLength()方法可以获取bookList的长度

System.out.println("一共有" + bookList.getLength() + "个title节点");

for (int i = 0; i < bookList.getLength(); i++) {

Node book = bookList.item(i);

NamedNodeMap attrs = book.getAttributes();

System.out.println("第 " + (i + 1) + "个title节点共有" + attrs.getLength() + "个属性");

for (int j = 0; j < attrs.getLength(); j++) {

//通过item(index)方法获取book节点的某一个属性

Node attr = attrs.item(j);

if (attr.getNodeName().equals("CONTENT")) {

String name = attr.getNodeName();

String value = attr.getNodeValue();

//获取属性名

// System.out.print("属性名：" + name);

//获取属性值

// System.out.println("--属性值: " + value);

String[] splitValue = value.split(",");

for (int k = 0; k < splitValue.length; k++) {

String resultValue = splitValue[k];

String[] splitResult = resultValue.split("=");

}

}

}
