[jdom-interest] Writing a list of currentElements using XMLOutputter

[Jeff Garza]

I wasn't able to figure out the correct way to use the for statement like
you suggested. I tried using the boolean isWanted = true for initialization,
isWanted = false for termination, and leaving increment blank, but that
didn't work. If you could explain how the proper way to use a for statement
in this situation that would help me a lot.

I also tried to place an if(listIterator.hasNext()) { statement but
depending on where I use it at, it either fails to close the stream and
freezes my computer or it won't do anything at all. The same happens with
while(listIterator.hasNext()).

Another thing I tried was to have the program access an existing file
instead of creating a new one:

                        SAXBuilder builder = new SAXBuilder();
                        try {
                            String curEl = new String(
currentElement.getAttribute("word").getValue());
                            Document doc = builder.build("file.txt");
                            Element incorrect = new Element("entry");
                            incorrect.setAttribute("word", "curEl");
                            doc.getRootElement().addContent(incorrect);
                            Format format = Format.getPrettyFormat();
                            format.setEncoding("UTF-8");
                            try {
                            XMLOutputter outputter = new
XMLOutputter(format);
                            outputter.output(doc, System.out);
                            System.out.flush();
                            }
                        catch (IOException e2) {
                            System.err.println(e2);
                        }
                        } catch (JDOMException e1) {
                            // TODO Auto-generated catch block
                            e1.printStackTrace();
                        } catch (IOException e1) {
                            // TODO Auto-generated catch block
                            e1.printStackTrace();
                        }

This appends the currentElement at the end of the list like I want it to but
it still manages to replace the previous element every time. It also puts an
unwanted "/" at the end which prevents the program from reading it: <entry
word = "word"  />

I wanted try creating a simple text file and modifying that but I need UTF-8
encoding and I only know how to create a simple txt file with FileWriter,
which doesn't allow UTF-8, so I didn't know how to proceed in doing that.

What do you think?
