In this section, you will learn how to check and locate an error in the XML document and error position.
Description of program:
The following program helps you in checking and locating an error in XML document.
Implementing this program you need a XML document. When you run the following program then it asks a xml file name and checks it. If the given file exists, the SAX Parser parses the XML document and detects the error in it at the specified line and column by using the getLineNumber() and getColumnNumber() methods. The getLineNumber method detects line of error and the getColumnNumber method also detects column of error and prints the line and column. If no any error in XML document, it will show a message "Employee-Detail.xml is well-formed". Whenever the given file doesn't exist, it displays "File not found!".
Here is the XML File: Employee-Detail.xml
|<?xml version = "1.0" ?>
<Emp_Id> E-001 </Emp_Id>
<Emp_Name> Vinod </Emp_Name>
<Emp_E-mail> Vinod1@yahoo.com </Emp_E-mail>
<Emp_Id> E-002 </Emp_Id>
<Emp_Name> Amit </Emp_Name>
<Emp_E-mail> Amit2@yahoo.com </Emp_E-mail>
<Emp_Id> E-003 </Emp_Id>
<Emp_Name> Deepak </Emp_Name>
<Emp_E-mail> Deepak3@yahoo.com </Emp_E-mail>
Here is the Java File: LocateError.java
Output of program:
Enter XML file name:Employee-Detail.xml
[Fatal Error] Employee-Detail.xml:19:11: The end-tag for element type "Employe"
must end with a '>' delimiter.
Employee-Detail.xml isn't well-formed
Error is at line number 19 and Column position 11
