Adding DOCTYPE in XML Document
Previous Home Next

In this program, we will be learn that how we can add a DOCTYPE to your XML file using the DOM application programming interfaces. This program is help to add a DOCTYPE in your XML file. Its Program takes a XML document name and checks it, the given file is exists or not. If the given file exists then it is parsed using the parse() method and a Document object tree is created . Abstract class Transformer is used to transform a source tree into a xml file The setOutputProperty() method invokes to the Transformer object and sets the system Id and public Id to the DOCTYPE in the XML file.

Example

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@yahoo.com </stu_E-mail>
</Student>
<Student>
<stu_Id> s-002 </stu_Id>
<stu_Name> Ajit </stu_Name>
<stu_E-mail> Ajit2@gmail.com </stu_E-mail>
</Student>
<Student>
<stu_Id> s-003 </stu_Id>
<stu_Name> Deepti </stu_Name>
<stu_E-mail> Deep3@yahoo.com </stu_E-mail>
</Student>
</Student_Detail>
