XML转Map方法一：
public static Map<String, String> readStringXml(String xml) throws DocumentException {
Document doc = DocumentHelper.parseText(xml);
Element books = doc.getRootElement();
System.out.println("rootNode:" + books.getName());
Iterator Elements = books.elementIterator();
Map<String, String> map = new HashMap<>();
while (Elements.hasNext()) {
Element user = (Element) Elements.next();
System.out.println("node=" + user.getName() + "\ttext=" + user.getText());
map.put(user.getName(), user.getText());
}
return map;
}
方法二：
public static Map<String, String> readStringXmlOut(String xml) {
Map<String, String> map = new HashMap<String, String>();
Document doc = null;
try {
doc = DocumentHelper.parseText(xml); // 将字符串转为XML
Element rootElt = doc.getRootElement(); // 获取根节点
@SuppressWarnings("unchecked")
List<Element> list = rootElt.elements();// 获取根节点下所有节点
for (Element element : list) { // 遍历节点
map.put(element.getName(), element.getText()); // 节点的name为map的key，text为map的value
}
} catch (DocumentException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return map;
