dom4j+xpath应用

应用一：
<?xml version="1.0" encoding="utf-8" ?>
- <ACCESOS>
   - <item>
       - <SOCIO>
              <NUMERO>00045050</NUMERO>
              <REPOSICION>0</REPOSICION>
              <NOMBRE>MOISES MORENO</NOMBRE>
           - <TURNOS>
                  <LU>T1</LU>
                  <MA>T2</MA>
                  <MI>T3</MI>
                  <JU>T4</JU>
                  <VI>T5</VI>
                  <SA>T6</SA>
                  <DO>T7</DO>
              </TURNOS>
          </SOCIO>
</item>
- <item>
       - <SOCIO>
              <NUMERO>00045051</NUMERO>
              <REPOSICION>0</REPOSICION>
              <NOMBRE>RUTH PENA</NOMBRE>
           - <TURNOS>
                  <LU>S1</LU>
                  <MA>S2</MA>
                  <MI>S3</MI>
                  <JU>S4</JU>
                  <VI>S5</VI>
                  <SA>S6</SA>
                  <DO>S7</DO>
              </TURNOS>
        </SOCIO>
      </item>
</ACCESOS>

1、导入dom4j与jaxen的jar包
2、读取时会比纯dom4j简单些：
   Document doc = new SAXReader().read(new File("D:/share/JavaProjects/drp/test_xmlImport/xml/test01.XML"));
   List itemList = doc.selectNodes("/ACCESOS/item/SOCIO");                   //dom4j+xpath的写法
   for (Iterator iter=itemList.iterator(); iter.hasNext();) {
       Element el = (Element)iter.next();
       String numero = el.elementText("NUMERO");
       String reposicion = el.elementText("REPOSICION");
       String nombre = el.elementText("NOMBRE");
       List turnosList = el.elements("TURNOS");
       for (Iterator iter1=turnosList.iterator(); iter1.hasNext();) {
           Element turnosElt = (Element)iter1.next();
           String lu = turnosElt.elementText("LU");
           String ma = turnosElt.elementText("MA");
           String mi = turnosElt.elementText("MI");
           String ju = turnosElt.elementText("JU");
           String vi = turnosElt.elementText("VI");
           String sa = turnosElt.elementText("SA");
           String doo = turnosElt.elementText("DO");
       }
   }


应用二：
<?xml version="1.0" encoding="UTF-8"?>
<config>
   <db-info>
       <driver-name>oracle.jdbc.driver.OracleDriver</driver-name>
       <url>jdbc:oracle:thin:@localhost:1521:bjpowern</url>
       <user-name>drp1</user-name>
       <password>drp1</password>
   </db-info>
   <dao-factory>
       <item-dao-facotry>com.bjpowernode.drp.basedata.dao.ItemDaoFactory4Oracle</item-dao-facotry>
       
       <user-dao-facotry>com.bjpowernode.drp.basedata.dao.UserDaoFactory4Oracle</user-dao-facotry>
   </dao-factory>
</config>

有如上xml，读取/item-dao-facotry节点下的信息
   List daoFactorylist = doc.selectNodes("/config/dao-factory/*");           //*是xpath语法，表示dao-factory的所有子节点
   for (int i=0; i<daoFactorylist.size(); i++) {
   Element daoFactoryElt = (Element)daoFactorylist.get(i);
   String tagName = daoFactoryElt.getName();                                                       //getName()：得到标签名
   String tagText = daoFactoryElt.getText();                                                       //getText()：得到文本内容
