一般我们会使用dom4j、SAX、w3c来解析xml文件，网上也大多提供此类解决方案。

但在实际项目中，也有会解析xml格式的字符串报文的。

比如，有如下字符串：

String = "
     
      OK
      
       
        201605110015
       
       
        070000314903
       
       
        http://10.202.18.24:8080/osms/wbs/print/printOrder.pub?mailno=vYrygnDPNe9Csjz35xwzwQ==
       
       
        http://10.202.18.24:8080/osms/wbs/print/printInvoice.pub?mailno=vYrygnDPNe9Csjz35xwzwQ==
       
      
     ";

对如上字符串进行格式化之后：

     	OK			
      			
       
        201605110015
       			
       
        070000314903
       			
       
        http://10.202.18.24:8080/osms/wbs/print/printOrder.pub?mailno=vYrygnDPNe9Csjz35xwzwQ==
       			
       
        http://10.202.18.24:8080/osms/wbs/print/printInvoice.pub?mailno=vYrygnDPNe9Csjz35xwzwQ==
       		
      	
     

即使格式化之后，我们也发现这串报文比较特殊，因为它使用了属性而不是元素节点来描述对象。

 

下面提供dom4j的解决方案：

public HashMap
     
       stringToXmlByDom4j(String content){		HashMap
      
        result = new HashMap
       
        ();				try {		SAXReader saxReader=new SAXReader();	        org.dom4j.Document docDom4j=saxReader.read(new ByteArrayInputStream(content.getBytes("utf-8")));	        org.dom4j.Element root = docDom4j.getRootElement();	        List
        
          rooAttrList = root.attributes();	        for (Attribute rootAttr : rooAttrList) {	            System.out.println(rootAttr.getName() + ": " + rootAttr.getValue());	            result.put(rootAttr.getName(), rootAttr.getValue());	           }	        	        List
         
           childElements = root.elements();	        	        for (org.dom4j.Element e1 : childElements) {	            System.out.println("第一层："+e1.getName() + ": " + e1.getText());	            result.put(e1.getName(), e1.getText());	           } 	        	        for (org.dom4j.Element child : childElements) {	         //未知属性名情况下	         List
          
            attributeList = child.attributes(); for (Attribute attr : attributeList) { System.out.println("第二层："+attr.getName() + ": " + attr.getValue()); result.put(attr.getName(), attr.getValue()); } //已知属性名情况下// System.out.println("id: " + child.attributeValue("id")); //未知子元素名情况下 List
           
             elementList = child.elements(); for (org.dom4j.Element ele : elementList) { System.out.println("第二层："+ele.getName() + ": " + ele.getText()); result.put(ele.getName(), ele.getText()); List
            
              kidAttr = ele.attributes(); for (Attribute kidattr : kidAttr) { System.out.println("第三层："+kidattr.getName() + ": " + kidattr.getValue()); result.put(kidattr.getName(), kidattr.getValue()); } List
             
               lidList = ele.elements(); int size = lidList.size(); if(size>0){ for (org.dom4j.Element e2 : lidList) { System.out.println("第三层："+e2.getName() + ": " + e2.getText()); result.put(e2.getName(), e2.getText()); } } }// System.out.println(); //已知子元素名的情况下// System.out.println("title" + child.elementText("title"));// System.out.println("author" + child.elementText("author")); //这行是为了格式化美观而存在// System.out.println(); } } catch (Exception e) { e.printStackTrace(); } return result; }
             
            
           
          
         
        
       
      
     

 

写一个main方法测试结果如下：

响应结果：
     
      OK
