So to give a complete overview:
I have a list of objects as displayed
[CODE=java]Registry(Student=[Student(Gender=M, School=Hamburg, FirstName=RP, Value=null),
Student(Gender=F, School=Berlin, FirstName=SK, Value=null),
Student(Gender=M, School=Frankfurt, FirstName=TK, Value=null)])[/CODE]
This represents the XML structure after unmarshalling. The original structure of the XML is shown below
[CODE=xml]<?xml version="1.0" encoding="UTF-8"?>
<Registry xmlns="http://www.registar.com"
xmlns:ms ="http://www.registar.com/ScoreVariant">
<Student Gender = "M" School = "Hamburg">
<FirstName>RP</FirstName>
</Student>
<Student Gender = "F" School = "Berlin">
<FirstName>SK</FirstName>
</Student>
<Student Gender = "M" School = "Frankfurt">
<FirstName>TK</FirstName>
</Student>
</Registry>[/CODE]
There are classes written for Registry, Student and Value with getter and setter methods (used lombok package)
Now, I want to scan through the list of objects, Look for school location, and if the location is "Berlin", I want to add another student.
[CODE=java] List<Registry> entries = new ArrayList<Registry>();
for (Registry e: entries) {
for (Student s : e.getStudent()) {
if (s.getSchool().equals("Berlin")) {
Student obj = new Student();
obj.setFirstName("MP");
obj.setGender("F");
obj.setSchool("Berlin"); // (1)
}
}
}[/CODE]
(1) Here I can create new object, but I am not able to add it to the XML (as the registry class has the ```List<Student> student``` as a property.
Ultimately, I want to have a output like the below
[CODE=java]Registry(Student=[Student(Gender=M, School=Hamburg, FirstName=RP, Value=null),
Student(Gender=F, School=Berlin, FirstName=SK, Value=null),
Student(Gender=F, School=Berlin, FirstName=MP, Value=null),
Student(Gender=M, School=Frankfurt, FirstName=TK, Value=null)])[/CODE]
