读取xml文件 解析双层xml

1、读取本地xml文件

/**
 * 加载本地配置文件
 * @author HuangXuebin
 * @date 2012-10-11
 * @Version V 1.0
 */
public class LoadConfig {
private static Logger logger = Logger.getLogger(LoadConfig.class);
private static String localFilePatch;
private static String ftpUrl;
private static String ftpUser;
private static String ftpPassword;
private static String ftpFilePatch;
static {
        load();//加载文件
    }
private static void load() {
       SAXReader reader = new SAXReader();
       try {
           Document doc = reader.read(LoadConfig.class.getClassLoader().getResourceAsStream("systemConfig.xml"));//classpatch下的配置文件
           Element root = doc.getRootElement();
           Iterator iterlocal = root.elementIterator("local");//得到local节点 
           while (iterlocal.hasNext()) {
            Element localEle = (Element) iterlocal.next();  
               localFilePatch = localEle.elementTextTrim("filePatch"); // 拿到local节点下的子节点的值
           }
           Iterator iterftp = root.elementIterator("ftp");//得到ftp节点
           while (iterftp.hasNext()) {
            Element ftpEle = (Element) iterftp.next();  
            ftpUrl = ftpEle.elementTextTrim("url"); // 拿到local节点下的子节点的值
            ftpUser = ftpEle.elementTextTrim("user");
            ftpPassword = ftpEle.elementTextTrim("password");
            ftpFilePatch = ftpEle.elementTextTrim("filePatch");
           }
           
       } catch (DocumentException e) {
        logger.info("========== 加载配置信息错误！==========");
           throw new ExceptionInInitializerError(e);
       }
       
   }
public static String getLocalFilePatch() {
return localFilePatch;
}
public static void setLocalFilePatch(String localFilePatch) {
LoadConfig.localFilePatch = localFilePatch;
}
public static String getFtpUrl() {
return ftpUrl;
}
public static void setFtpUrl(String ftpUrl) {
LoadConfig.ftpUrl = ftpUrl;
}
public static String getFtpUser() {
return ftpUser;
}
public static void setFtpUser(String ftpUser) {
LoadConfig.ftpUser = ftpUser;
}
public static String getFtpPassword() {
return ftpPassword;
}
public static void setFtpPassword(String ftpPassword) {
LoadConfig.ftpPassword = ftpPassword;
}
public static String getFtpFilePatch() {
return ftpFilePatch;
}
public static void setFtpFilePatch(String ftpFilePatch) {
LoadConfig.ftpFilePatch = ftpFilePatch;
}


 
}
           

2、读取xml里嵌套的xml

/**
     * 解析返回结果
     * @param xml
     * @return
     */
    public Integer readStringXml(String xml) {
        Document doc1 =null;
        Document doc2 =null;
        String MobileNum = "";
        String SubOrderID = "";
        String ItemCode = "";
        Integer Result = 99;
        try {
            // 下面的是通过解析xml字符串的
            doc1 = DocumentHelper.parseText(xml); // 将字符串转为XML
            Element rootElt1 = doc1.getRootElement(); // 获取根节点
            String SvcCont = rootElt1.elementTextTrim("SvcCont");// 获取根节点下的子节点SvcCont的值即内层xml
            //进行第二次解析
            doc2 = DocumentHelper.parseText(SvcCont); // 将字符串转为XML
            Element rootElt2 = doc2.getRootElement(); // 获取根节点
            //一下取得相应节点的值
            MobileNum = rootElt2.elementTextTrim("MobileNum");
            SubOrderID = rootElt2.elementTextTrim("SubOrderID");
            ItemCode = rootElt2.elementTextTrim("ItemCode");
            Result = Integer.parseInt(rootElt2.elementTextTrim("Result"));
            //写入日志
            logger.info("兑换云南省BOSS业务用户手机号:[" + MobileNum +"]订单号:["+SubOrderID+"商品编号:["+ItemCode+"]结果代码:["+Result+"]");
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return Result;
    }
