Previous Home Next

In this program, we will learn to find an element in the specified XML file using DOM APIs defined in the org.apache.xerces.parsers.DOMParser package. Your classpath must contain xercesImpl.jar and xml-apis.jar files to run this program. You can download it from Xerces

Here is the XML File: Student_Detail.xml

<?xml version = "1.0" ?>
<Student_Detail>
<Student>
<stu_Id> s-001 </stu_Id>
<stu_Name> samir </stu_Name>
<stu_E-mail> sam1@gmail.com </stu_E-mail>
