JSP中如何生成XML文档？

Question

我做的一个网上书店~~
用户没确定订单的时候~
我把客户说选择的书籍的相关信息写入到XML文件中~~
在JSP中如何生成一个XML文档啊？

Answer 1

自己用StringBuffer拼,最后用File输出个.xml的文件就可以了

Answer 2

io也可以
不过你要自己建个xml文件先

Answer 3

大哥大姐~~~我想使用JDOM~~
相应的代码在JAVA中调试成功了~~也生成了XML文件~~~
但是就是在JSP中调试不成功~~~我郁闷啊~~

Answer 4

以前做的例子
package xml;import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMResult;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;import org.w3c.dom.Document;
import org.w3c.dom.Element;import util.conManager;public class DBtoXML {
public static void main(String[] args) throws Exception{
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
DocumentBuilder db=dbf.newDocumentBuilder();
Document doc=db.newDocument();
Connection con=conManager.gerCon();
PreparedStatement ps1=con.prepareStatement("select * from customer");

ResultSet rs1=ps1.executeQuery();
Element customers=doc.createElement("customers");
while(rs1.next())
{
String s_customerID=rs1.getString(1);
Element customer=doc.createElement("customer");
Element customerID=doc.createElement("customerID");
Element customerName=doc.createElement("customerName");
Element sex=doc.createElement("sex");
customerID.appendChild(doc.createTextNode(s_customerID));
customerName.appendChild(doc.createTextNode(rs1.getString(2)));
sex.appendChild(doc.createTextNode(rs1.getString(3)));

customer.appendChild(customerID);
customer.appendChild(customerName);
customer.appendChild(sex);
System.out.println(s_customerID+"aaaaaaa"+customerName.getFirstChild().getNodeValue());
Element buySet=doc.createElement("buySet");
customer.appendChild(buySet);
PreparedStatement ps2=con.prepareStatement("select * from buy where customerID='"+s_customerID+"'");
ResultSet rs2=ps2.executeQuery();

buySet.setAttribute("customerID", s_customerID);
while (rs2.next()) {
Element buyName=doc.createElement("buyName");
Element amount=doc.createElement("amount");
Element price=doc.createElement("price");

buyName.appendChild(doc.createTextNode(rs2.getString(2)));
amount.appendChild(doc.createTextNode(rs2.getString(3)));
price.appendChild(doc.createTextNode(rs2.getString(4)));


buySet.appendChild(buyName);
buySet.appendChild(amount);
buySet.appendChild(price);
}
rs2.close();
customers.appendChild(customer);
}
rs1.close();

con.close();
doc.appendChild(customers);
TransformerFactory tff=TransformerFactory.newInstance();

Transformer tformer=tff.newTransformer();

tformer.transform(new DOMSource(doc), new StreamResult("c://a.xml"));
}}
