dom4j解析復雜的xml文件

待解析的xml文件：

j用dom4j解析該xml文件

需要導入的jar包：
import org.apache.log4j.Logger;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.Node;
import org.dom4j.io.SAXReader;

//dom4j解析xml
//創建SAXReader對象 reader
SAXReader reader = new SAXReader();
//因為我項目中的xml文件 是查出來的，類型是字符串類型，所以我們需要把字符串轉換成xml文件
String resultxml = broadBandResult.getReviceXML();//我拿到的字符串類型的返回報文
                        
Document document = DocumentHelper.parseText(resultxml); //將字符串轉換成xml，具體轉換 可以百度搜索 dom4j字符串轉xml
//獲取文件的根節點
Element root = document.getRootElement();
String node1Name = "需展示的節點名稱"；
//得到節點的值  /ResInfo/asset/assetcardno為需要得到哪個節點的路徑
//這里我要得到assetcardno節點的值

String node1text =  root.selectSingleNode("/ResInfo/asset/assetcardno").getText();String node2Name = "描述"; 

String node2text = root.selectSingleNode("/ResInfo/asset/comments").getText(); 

//因為項目需要拼接html ，這一部分大家可以略過不看 
desc.append("<div class=\"mui-input-row\" style=\"-webkit-user-select:text;height:30%\"><label>"+node1Name+"</label><label name='"+node1text+"' id='"+node1text+"1' style=\"width: 60%;\">"+node1text+"</label></div>") 
.append("<div class=\"mui-input-row\" style=\"-webkit-user-select:text;height:30%\"><label>"+node2Name+"</label><label name='"+node2text+"' id='"+node2text+"1' style=\"width: 60%;\">"+node2text+"</label></div>") 

//得到containers節點 
Node node1 = root.selectSingleNode("/ResInfo/containers"); 
//得到containers節點下邊的子節點container，因為有多個container，所以用list集合接收 
List<Element> list = ((Element) node1).elements("container"); 

//循環這個集合 
for (Element element : list) { 
 String node13Name = "機框安裝高度"; 
 //得到container節點里面的shelfhight節點 
      Element node13 =element.element("shelfhight"); 
 //得到shelfhight節點的值 
      String node13Text = node13.getText(); 

 //拼接html 
         desc.append("<li class=\"mui-table-view-cell\" ><div style=\"width: 80%;float: left;\"></div><br/>") 
 .append("<div><label>"+node13Name+"</label><label name='"+node13Text+"' id='"+node13Text+"1' style=\"width: 60%;\">"+node13Text+"</label></div><br/>"); 

 //得到container節點里面的cardinfos 
         Element node14 =(Element) element.selectSingleNode("cardinfos"); 

 if(node14 != null){ 
 logger.error("===node14==="+node14); 

 //得到cardinfos節點里面的cardinfo節點，因為cardinfos節點里面有多個cardinfo節點，所以用List集合接收 
               List<Element> childList2 =node14.elements("cardinfo"); 
 logger.error("===childList2集合長度==="+childList2.size()); 
 //循環childList2 集合 
 for (Element element2 : childList2) { 
 String node15Name = "機框下的板卡拼裝名稱列表";
 //得到cardinfo節點里面的cardname節點 
                      Element node15 =element2.element("cardname"); 
 //得到cardname節點的值 
                      String node15Text = node15.getText(); 
 // 拼接html
 desc.append("<div><label name='"+node15Text+"' id='"+node15Text+"1' style=\"width:60%;\">"+node15Text+"</label></div><br/>"); 
 } 
 } 
 desc.append("</li>"); 
}

 這樣就解析完了一個xml文件。。。。這只是我記錄工作中碰到的問題，歡迎各位大神予以糾正指錯
