使用jsoup解析xml

上一篇 / 下一篇 2013-01-18 09:25:42 / 个人分类：Java学习

刚接触了点jsoup的东西，貌似可以用来解析xml文件，xml文件格式如下：
<Data>
    <BasicInfo>
        <Name>KYO</Name>
        <Gender>Male</Gender>
        <Birthday>26/03/2010</Birthday>
    </BasicInfo>
    <Address>
        <Country>China</Country>
        <City>shanghai</City>
        <PostalCode>200000</PostalCode>
    </Address>
    <Comment>
    </Comment>
</Data>

代码参考如下：
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Node;
import org.jsoup.select.Elements;

public class XMLOperationByJSoup {
   public String xmlFile;

   public XMLOperationByJSoup(String file) throws Exception{
      this.xmlFile = file;
   }

   public Document getXMLDocumentObject() throws Exception{
      Document doc = null;
      try{
            File input = new File(xmlFile);
            doc = Jsoup.parse(input, "UTF-8");
      } catch (FileNotFoundException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
      return doc;
   }

    //通过xml节点来获取其下的所有属性名
   public List getXMLAttributesByNode(String nodeName) throws Exception{
      Document doc = getXMLDocumentObject();
      Elements ele = doc.getAllElements();
      String strTagName = "";
      List arrNode = new ArrayList();

      System.out.println("size=" + ele.size());
      for(int i=0;i
         strTagName = ele.get(i).tagName().trim().toLowerCase();
         if(nodeName.toLowerCase().equals(strTagName)){
            List list = ele.get(i).childNodes();
            System.out.println("list size=" + list.size());
            for(int j=0;j
               String node = list.get(j).nodeName();
               if(!node.equals("#text")){
                  arrNode.add(node);
               }
            }
         }
      }
      return arrNode;
   }
   //通过xml节点及属性名来获取值
   public String getXMLAttributeValueByNode(String nodeName, String attName) throws Exception{
      Document doc = getXMLDocumentObject();
      Elements ele = doc.getAllElements();
      String strTagName = "";
      String attValue = "";

      System.out.println("size=" + ele.size());
      for(int i=0;i
         strTagName = ele.get(i).tagName().trim().toLowerCase();
         if(nodeName.toLowerCase().equals(strTagName)){
            Elements nodeEle = ele.get(i).getElementsByTag(attName);
            System.out.println("nodeEle size=" + nodeEle.size());
            if(nodeEle.size() > 0){
               for(int j=0;j
                  attValue = nodeEle.get(j).text().trim();
               }
            }
            else{
               System.out.println("attName[" + attName + "] cannot be found!");
            }
         }
      }
      return attValue;
   }
}

调用如下：
public static void main(String[] args) throws Exception {
      String xmlFile = "D:\\MyAutoFrameTest\\jsoup.xml";
      XMLOperationByJSoup xml = new XMLOperationByJSoup(xmlFile);
      System.out.println("att value= " + xml.getXMLAttributeValueByNode("BasicInfo", "Name"));

      List list = xml.getXMLAttributesByNode("BasicInfo");
      for(int i=0;i
         System.out.println("list node = " + list.get(i));
      }
   }
