java解析xml工具类[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

public class XmlUtils {
    /**  * 解析xml数据  * */  public static Map<String,Object> parseXml(byte[] xmlBytes, String charset) {
        SAXReader reader = new SAXReader(false);
        InputSource source = new InputSource(new ByteArrayInputStream(xmlBytes));
        source.setEncoding(charset);
        Map<String,Object> map = new HashMap<String, Object>();
        try {
            Document doc = reader.read(source);
            Iterator<Element> iter = doc.getRootElement().elementIterator();
            while (iter.hasNext()) {
                Element e = iter.next();
                if (!e.elementIterator().hasNext()) {
                    map.put(e.getName(),e.getTextTrim());
                    continue;
                }
                Iterator<Element> iterator = e.elementIterator();
                Map<String,String> param = new HashMap<String, String>();
                while (iterator.hasNext()) {
                    Element el = iterator.next();
                    param.put(el.getName(),el.getTextTrim());
                }
                map.put(e.getName(),param);
            }
        }catch (Exception e) {
            LogUtils.error("XmlParseError",e);
        }
        return map;
    }

    public static Map<String,String> parseXml(String xml) {
        if (StringUtils.isBlank(xml)) {
            return null;
        }
        Map<String,String> result = new HashMap<String, String>();
        try {
            Map<String,Object> map = parseXml(xml.getBytes("UTF-8"), "UTF-8");
            for (String key:map.keySet()) {
                Object value = map.get(key);
                result.put(key, String.valueOf(value));
            }
            return result;
        }catch (Exception e) {
            LogUtils.error("parse_xml_error", e);
        }
        return null;
    }
}
