dom4j解析复杂的xml文件

待解析的xml文件:

j用dom4j解析该xml文件

需要导入的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
//创建SAXReader对象 reader
SAXReader reader = new SAXReader();
//因为我项目中的xml文件 是查出来的,类型是字符串类型,所以我们需要把字符串转换成xml文件
String resultxml = broadBandResult.getReviceXML();//我拿到的字符串类型的返回报文
                        
Document document = DocumentHelper.parseText(resultxml); //将字符串转换成xml,具体转换 可以百度搜索 dom4j字符串转xml
//获取文件的根节点
Element root = document.getRootElement();
String node1Name = "需展示的节点名称"//得到节点的值  /ResInfo/asset/assetcardno为需要得到哪个节点的路径
//这里我要得到assetcardno节点的值
String node1text =  root.selectSingleNode("/ResInfo/asset/assetcardno").getText();String node2Name = "描述"; 
String node2text = root.selectSingleNode("/ResInfo/asset/comments").getText(); 

//因为项目需要拼接html ,这一部分大家可以略过不看
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节点
Node node1 = root.selectSingleNode("/ResInfo/containers");
//得到containers节点下边的子节点container,因为有多个container,所以用list集合接收
List<Element> list = ((Element) node1).elements("container");

//循环这个集合
for (Element element : list) {
String node13Name
= "机框安装高度";
//得到container节点里面的shelfhight节点
Element node13 =element.element("shelfhight");
//得到shelfhight节点的值
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节点里面的cardinfos
Element node14 =(Element) element.selectSingleNode("cardinfos");

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

//得到cardinfos节点里面的cardinfo节点,因为cardinfos节点里面有多个cardinfo节点,所以用List集合接收
List<Element> childList2 =node14.elements("cardinfo");
logger.error(
"===childList2集合长度==="+childList2.size());
//循环childList2 集合
for (Element element2 : childList2) {
String node15Name
= "机框下的板卡拼装名称列表";
//得到cardinfo节点里面的cardname节点
Element node15 =element2.element("cardname");
//得到cardname节点的值
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>");
}

 这样就解析完了一个xml文件。。。。这只是我记录工作中碰到的问题,欢迎各位大神予以纠正指错
