[jdom-interest] Cannot close an XML file used for parsing

Hi All,

I appears to have difficulty closing (possibly flushing it first) an XML file that was subsequently being parsed without success. The error generated is:

org.jdom.input.JDOMParseException: Error on line 23: The element type "form" must be terminated by the matching end-tag "</form>".

Below is the code snippets of readData() to retrieve (HTML) data from a website, save it to a file, then convert to XML format before returning the new filename:
public String readData() {
 
    try {
          URL url  = new URL("http://www.abc.com");
          URLConnection connection = url.openConnection();      
          InputStream isInHtml = url.openStream();   // throws an IOException    
          disInHtml = new DataInputStream(new BufferedInputStream(isInHtml));         
          System.out.flush();
          FileOutputStream fosOutHtml = null;
          fosOutHtml = new FileOutputStream("C:\\Temp\\ABC.html");
          int oneChar, count=0;
          while ((oneChar=disInHtml.read()) != -1)
              fosOutHtml.write(oneChar);
      }
      catch { ... }
      finally {
          isInHtml.close();
          disInHtml.close();
          fosOutHtml.flush(); // optional
          fosOutHtml.close();
      }
    }
 
    try {
          File fileInHtml = new File("C:\\Temp\\ABC.html");
          FileReader frInHtml = new FileReader(fileInHtml);
          BufferedReader brInHtml = new BufferedReader(frInHtml);
          String string = "";
          while (brInHtml.ready())
              string += brInHtml.readLine() + "\n";
          fwOutXml  = new FileWriter("C:\\Temp\\ABC.xml");
          pwOutXml  = new PrintWriter(fwOutXml);
          light_html2xml html2xml = new light_html2xml();
          pwOutXml.print(html2xml.Html2Xml(string));
    }
    catch { ... }
    finally {
        fwOutXml.close();
        pwOutXml.close();
    }
    return fileInHtml.getAbsolutePath();
}
 
// parseData reads the XML file using the name returned by readData()
public void parseData(String XMLFilename)
{
    try
    {
        FileReader frInXml = new FileReader(FileName);
        BufferedReader brInXml = new BufferedReader(frInXml);
        SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser"); // JDOMParseException generated.
        ....
}
These codes would worked when they were in a single method but I have since placed some structure around them using a number methods.

This issue has risen in th past where I have been able to close the XML file prior to reading them again. However, I don't have a solution for it this time round.

I am running JDK 1.6.0_10, Netbeans 6.1, JDOM 1.1 on Windows XP platform.

Any assistance would be appreciated.

Many thanks,

Jack
