java操作xml

Posted 2020-08-31 蔚蓝星空

1、将对象转换成xml，需要先导入XStream jar包，下载地址：http://x-stream.github.io/download.html

XStream xs = new XStream();
String xmlStr= xs.toXML(obj);

2、将对象转换成xml，并用流输出

XStream xs = new XStream();
xs.toXML(obj,outputStream);

3、将xml转换成map，需要先导入dom4j jar包，下载地址：https://sourceforge.net/projects/dom4j/files

Map<String, String> map = new HashMap<String, String>();
SAXReader sr = new SAXReader();
Document doc = null;
try {
　　doc = sr.read(inputStream);
} catch (DocumentException e) {
　　e.printStackTrace();
}
Element root = doc.getRootElement();
List<Element> elements = root.elements();
for (Element element : elements) {
　　map.put(element.getName(), element.getText());
}
