Today we are going to know how to read data from xml file and show it in jsp page.
First create a xml file ex:"names.xml" like below

Quote:<?xml version="1.0"?>
<xmldata>
<student>
<RegistrationNo>1</RegistrationNo>
<StudentID>31313</StudentID>
<Name>sample</Name>
<FName>Mr.sample</FName>
</student>

Now we have to write the coding to read each and every parent and sub node so we write code as follows

<%@ page contentType="text/html"%>
<%@ page import="javax.xml.parsers.DocumentBuilderFactory,javax.xml.parsers.DocumentBuilder,org.w3c.dom.*"%>
<% DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse("http://localhost:8084/s2sgatewayxml/names.xml");

NodeList RegistrationNo = doc.getElementsByTagName("RegistrationNo");
NodeList StudentID = doc.getElementsByTagName("StudentID");
NodeList Name = doc.getElementsByTagName("Name");
NodeList FName = doc.getElementsByTagName("FName");

%>

Quote:<html>
<head>
<meta></meta>
<title>s2sgateway tutorials: XML with JSP : webmaster@s2sgateway.com</title>
</head>
<body>
<table border=0 bgcolor="green" width=80% cellspacing=2 cellpadding=2 align=center>
<tr>
<td style="font-family:arial,verdana;font-size:9pt;">
Reading XML Data from JSP
</td>
</tr>
</table>
 
<table border=0 width=80% style="border: thin groove white;" cellspacing=2 cellpadding=2 align=center>
<tr>
<td bgcolor="green"> </td>
<td bgcolor="green">RegistrationNo</td>
<td bgcolor="green">StudentID</td>
<td bgcolor="green">Name</td>
<td bgcolor="green">FName</td>
</tr>
<%int i;
for (i=0;i<=RegistrationNo.getLength()-1;i++)
{%>
<tr>
<td>



</td>
<td>

<%= RegistrationNo.item(i).getFirstChild().getNodeValue()%>

</td>
<td>

<%= StudentID.item(i).getFirstChild().getNodeValue()%>

</td>
<td>

<%= Name.item(i).getFirstChild().getNodeValue()%>

</td>
<td>

<%= FName.item(i).getFirstChild().getNodeValue()%>

</td>
</tr>
<%}%>
</table>
</body>
</html>

here Document doc = db.parse("http://localhost:8084/s2sgateway.comxml/names.xml");
is the location of xml file if your location is just localhost change according to that.
Download Full Source and paste it to webapps folder of tomcat and run it. Any question ask us.

Happy coding
