You can pass the paths to the three files as command line arguments, read them in your main method then load the XML files. e.g.:

public static void main(String [] args) {
     // there is some obvious scope for erros here
     // so you'd put some validation code here:
     .....
 
     // get the file names
     String file1 = args[0];
     String file2 = args[1];
     String file3 = args[2];
 
    // now you have the file names 
    // you need to use java.io to read the file
    // and a parser to parse it. SAX would 
    // look something like this:
    SAXParserFactory factory = SAXParserFactory.newInstance();
    factory.setValidating(true);
    factory.newSAXParser().parse(new File(file1), new MyDefaultHandler());
 
 
}

(Please note the above code is deliberately simplistic - you'll have to write the Handler, and think about what you do with regards to Exception handling and validation)

To actually run Paul's example from the command line, you would type

java SomeClass file1.xml file2.xml file3.xml

I don't know how Eclipse handles command-line arguments. You should search through the project options to see if you can figure out how to set them. If you don't find anything, ask your question in the IDE forum.

p.s. You might also want to modify Paul's example to take any number of command-line arguments. This way the user can specify 1 or 500, if they wish. Of course, this depends on whether or not this type of usage is meaningful for your program.

In the run window, there is Arguments tab. Here you can type whatever arguments you want to send to your program.
Hope this works out for you.
