Question

So I want to read data from an xml file, I am now at a point where I have XMLReader and ContentHandler in place and when the endDocument() is fired I have “collected” all the data I need from the document.

But now it seems that I ran into a wall…

How do I return the collected data (from the ContentHandler) so that it can be used in my application?

Answer 1

You may create a List<T> in ContentHandler.

public class MyTextHandler implements ContentHandler {
  ....
  private ArrayList<YourModel> list;

  public MyTextHandler() {
    list= new ArrayList<YourModel>();
  }
  public ArrayList<YourModel> getList() {
    return list;
  }
  ....
}

Obtain list from the Handler:

MyTextHandler handler=new MyTextHandler();
reader.setContentHandler(handler);
InputSource is = new InputSource(filename);
reader.parse(is);

ArrayList<YourModel> list=handler.getList();
