各位大哥,大姐,小弟,小妹帮个忙!谢谢!
各位高手帮个忙，我是一个学JSP的新手。我用JSP+XML编了一个程序，编译可以通过，但是运行显示JSP界面的时候，报SAXEXCEPTION：值必须加引号。请问这是什么问题？（用JBUILDER9的TOMCAT4.0编译）
源代码如下：
<%@ page import="javax.xml.parsers.*"%>;
<%@ page import="javax.xml.transform.*"%>;
<%@ page import="javax.xml.transform.dom.DOMSource"%>;
<%@ page import="javax.xml.transform.stream.StreamResult"%>;
<%@ page import="org.w3c.dom.*"%>;
<%@ page import="org.w3c.dom.Element"%>;
<%@ page import="java.io.File"%>;
<body>
<%
DocumentBuilderFactory factory=null;
DocumentBuilder builder=null;
Document doc=null;
factory = DocumentBuilderFactory.newInstance();
builder=factory.newDocumentBuilder();
doc=builder.parse("data/restaurants.xml");
doc.normalize();
String name="adf";
int intNum=0;
Element restNum=(Element)doc.getElementsByTagName("restaurants").item(0);
intNum=Integer.parseInt(restNum.getAttributeNode("num").getNodevalue());
intNum+=1;
//为restaurants的属性num 的数值加1
restNum.getAttributeNode("num").setNodevalue(String.valueOf(intNum));
//新增节点
Element newRestaurant=doc.createElement("restaurant");
Attr newArrId=doc.createAttribute("id");
//Attribute newArrId = new Attribute("id",String.valueOf(intNum));
textseg=doc.createTextNode(String.valueOf(intNum));
newArrId.setvalue(String.valueOf(intNum));
newRestaurant.setAttributeNode(newArrId);
Element newName=doc.createElement("name");
textseg=doc.createTextNode(strName);
newName.appendChild(textseg);
newRestaurant.appendChild(newName);
doc.getDocumentElement().appendChild(newRestaurant);
////////以下函数将数据写入XML文件
TransformerFactory tfactory = TransformerFactory.newInstance();
Transformer transformer = tfactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult("data/restaurants.xml");
%>
</body>
restaurant.xml:
<?xml version="1.0"encoding="gb2312"?>
<restaurants num=1>
<restaurant id=1>
</restaurant>
</restaurants>
