没有闭合（结束）标签XML文件的解析

先上XML文件：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <RESULT_INFO>
    	<PATIENT>
    		<origin value="XX科技公司" />
    		<id value="1234568" />
    		<name value="李四" />
    		<sex value="男" />
    		<age value="20" />
    		<exmatime value="2018-01-26 18:26:37" />
    	</PATIENT>
    	<DATAINFO>
    		<samplerate value="500" />
    		<baseline value="32768" />
    		<advalue value="262" />
    		<channels value="9" />
    		<channelbyte value="4" />
    		<analysechannel value="6" />
    	</DATAINFO>
    	<EXAM_RESULT>
    		<hr value="0" />
    		<p_time value="0" />
    		<pr_interval value="0" />
    		<qrs_time value="0" />
    		<qt_interval value="0" />
    		<qtc_interval value="0" />
    		<p_axis value="0.0" />
    		<qrs_axis value="0.0" />
    		<t_axis value="0.0" />
    		<qrs_t value="0.0" />
    		<sys_conclusion value="心率正常" />
    		<minnsotCode value="157，152，136，139，158，139" />
    	</EXAM_RESULT>
    	<print_time value="2018-01-26 18:14:33" />
    </RESULT_INFO>

该XML文件与平常所见XML有所不同，我们常见的XML文件是这样的：

<?xml version="1.0" encoding="utf-8"?>
    <ROOT>
    <VERSION>1.0</VERSION>
    <USER>5</USER>
    <TYPE>SPO2</TYPE>
    <SOURCE>IOS</SOURCE>
    <content>
    <ITEM>
    <SPO2>97</SPO2>
    <PR>70</PR>
    <PI>48</PI>
    <TIME>2017-01-06 10:49:10</TIME>
    </ITEM>
    </content>
    </ROOT>

那么非闭合标签的XML文件怎样读取，才能拿到子节点如minnsotCode 的属性值呢，刚开始我使用的是DOM解析，大致是这样，详细代码我就不贴出来了：

DocumentBuilderFactory factory1 = DocumentBuilderFactory.newInstance();
      DocumentBuilder builder = factory1.newDocumentBuilder();
      Document doc = builder.parse(“demo.xml”);
      NodeList Item = doc.getElementsByTagName("EXAM_RESULT");
      for (int i = 0; i < Item.getLength(); i++) {
    		String minnsotCode =doc.getElementsByTagName("minnsotCode ").item(i).getFirstChild().getNodeValue();
    				
              }

运行后报空指针异常  
后使用dom4J解析，终于拿到值。

import java.io.File;  
    import java.util.Iterator;
    import java.util.List;  
    import org.dom4j.Attribute;  
    import org.dom4j.Document;  
    import org.dom4j.Element;  
    import org.dom4j.Node;
    import org.dom4j.io.SAXReader; 
    
    public static void main(final String[] args) {  
    	        final SAXParserHandler test = new SAXParserHandler();  
    	        try {  
    	             
    	            ECG12 ecg12=test.GetECGData("E:\\test\\20170828.xml");
    	            System.out.println(ecg12.getHeartRate());
    		        System.out.println(ecg12.getECGResult());
    		        System.out.println(ecg12.getMinnsotCode ());
    	        } catch (final Exception e) {  
    	            e.printStackTrace();  
    	        }  
    	    }  
    	  
    	     
    	 public static ECG12 getECG12Test(final Element node)
    	 {
    	     	ECG12 ecg12=new ECG12();
    	        getNodes(node,ecg12);
    	        return ecg12;
    	 }
    	 
    	    public ECG12 GetECGData(String path) throws Exception {  
    	    	final SAXReader sax = new SAXReader();
    	        final File xmlFile = new File(path);  //"E:\\test\\20170828.xml"
    	        final Document document = sax.read(xmlFile);
    	        final Element root = document.getRootElement();
    	        ECG12 ecg12 = getECG12Test(root);
    	        
    	        return ecg12;
    	      
    	       
    	    }  
    	  
    	    
    	    public static void getNodes(final Element node,ECG12 ecg12) 
    	    {  
    	        
                final List<Attribute> listAttr = node.attributes();
    	        
    	        for (final Attribute attr : listAttr) 
    	        {
    	        	if(node.getName().equalsIgnoreCase("hr"))
    	        	{
    	        		 ecg12.setHeartRate(Integer.parseInt(attr.getValue()));
    	        		
    	        	} if(node.getName().equalsIgnoreCase("sys_conclusion"))
    	        	{
    	        		String ecgResult=attr.getValue();
    	        		ecg12.setECGResult(ecgResult);
    	        	
    	        	}else if(node.getName().equalsIgnoreCase("minnsotcode"))
    	        	{
    	        		String minnsotcode=attr.getValue();
    	        		ecg12.setECGData(minnsotcode);
    	        	}
    	         
    	        }  
    	        final List<Element> listElement = node.elements(); 
    	        for (final Element e : listElement)
    	        {           
    	            getNodes(e,ecg12);
    	        }
    		
    	    }  
    
    
     ```以上ECG12为要取值的实体类，最终目的拿到各个属性值赋值，然后在存进数据库，本人才疏学浅，如有不足之处，欢迎指正，同时如果有更好的解决办法，也欢迎提出。
