解析xml常用文档。 一:要操作的xml文件 xml.xml 二:要写进xml.xml文件的节点类映射 --MyInfo.java-- class MyInfo { public String name; public String telephone; public String address; public MyInfo(){} } 三:追加节点 www.yunlin.cn --AppendNode.java-- import java.io.*; import org.dom4j.*; import org.dom4j.io.*; class AppendNode { private String fileName; public AppendNode(String fileName) { this.fileName=fileName; } public void initFile() { try { org.dom4j.Element info=DocumentHelper.createElement("Info"); org.dom4j.Document root=DocumentHelper.createDocument(info); org.dom4j.io.XMLWriter xmlWriter=new XMLWriter(new java.io.FileOutputStream(this.fileName)); xmlWriter.write(root); }catch(java.io.FileNotFoundException e1){} catch(java.io.UnsupportedEncodingException e2){} catch(java.io.IOException e3){} } public void appendNode(MyInfo mi) { try { org.dom4j.Element myinfo=DocumentHelper.createElement("myinfo"); org.dom4j.Element name =DocumentHelper.createElement("name"); org.dom4j.Element telephone=DocumentHelper.createElement("telephone"); org.dom4j.Element address =DocumentHelper.createElement("address"); name.setText(mi.name); telephone.setText(mi.telephone); address.setText(mi.address); myinfo.add(name); myinfo.add(telephone); myinfo.add(address); org.dom4j.io.SAXReader reader=new SAXReader(); org.dom4j.Document root=reader.read(new java.io.FileInputStream(this.fileName)); org.dom4j.Element info=root.getRootElement(); info.add(myinfo); org.dom4j.io.XMLResult result=new XMLResult(new java.io.FileOutputStream(this.fileName)); org.dom4j.io.XMLWriter writer=result.getXMLWriter(); writer.write(root); }catch(java.io.FileNotFoundException e4){} catch(org.dom4j.DocumentException e5){} catch(java.io.UnsupportedEncodingException e6){} catch(java.io.IOException e7){} } } 四:主执行类 --XmlExec.java-- public class XmlExec { private AppendNode appendnode; private String filename; public XmlExec() { filename="xml.xml"; appendnode=new AppendNode(filename); appendnode.initFile(); -------------------------------------------------<1>------------- } public void xmlAppend() { MyInfo myinfo1=new MyInfo(); MyInfo myinfo2=new MyInfo(); myinfo1.name="wangkangfan"; myinfo1.telephone="123456789"; myinfo1.address="xiangjiang_xizihu"; myinfo2.name="shenmuzi"; myinfo2.telephone="987654321"; myinfo2.address="diao_yu_dao"; appendnode.appendNode(myinfo1); appendnode.appendNode(myinfo2); } public static void main(String args[]) { XmlExec xml=new XmlExec(); xml.xmlAppend(); --------------------------------------------<2>--------------- } } 五:Result view
