I/O error: InputSource: Stream closed

Question

Hi
I am new to XML. I am trying to modify XML content using DOM parser. After the modification I want to check if the changes have taken place or not by printing the XML on the console.
This is what I have done:
1. Read XML from InputSource
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.parse(inputSource);2. Get the nodes to Modify.
NodeList nodeList = (NodeList)doc.getElementsByTagName("XXX");3. Print the InputSource to check the changes.
BufferedReader readerTemp = new BufferedReader(new InputStreamReader(inputSource.getByteStream()));
               String inputLine;
                while ((inputLine = readerTemp.readLine()) != null) {
                  System.out.println(inputLine);
                }But however, when I try to view the changes I get an error STREAM CLOSED.
Please help me, how to open the inputSource again to read the stream from it... what can I do to solve this problem?

Answer 1

The parser closes the input source, having read it all the way to EOF. So there's nothing left to be read even if the parser didn't close the source.
So you need a new input source.
But are the changes taking place on the file, or just in the DOM? In which case re-reading the file won't show any changes - you will need to write the DOM out to the file.
In which case you can look at it with a text editor. Alternatively you can print the DOM to the console directly.
So you don't really need the answer to your original question.
