    <p>I am using dom4j to extract information in xml files(all in one folder). Here's my code:</p> <pre><code> File folder = new File("c:/folder directory"); File[] listOfFiles = folder.listFiles(); FileOutputStream foutstream = new FileOutputStream("c:/mozilla_expertlist.txt",true); PrintWriter writer = new PrintWriter(foutstream); for (File file: listOfFiles) { System.out.println(file.getName()); File f = new File("c:/Users/dahuo2013/workspace/mozilla_xml/"+file.getName()); SAXReader reader = new SAXReader(); reader.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false); reader.setEncoding("utf-8"); Document doc = reader.read(f); Element root = doc.getRootElement(); Element foo; for (Iterator i = root.elementIterator("bug"); i.hasNext();) { foo = (Element) i.next(); writer.println(foo.elementText("assigned_to")); } } writer.close(); </code></pre> <p>My code is working however it always have errors reporting. Then I found that when the xml file has NUL NUL NUL characters. It shows error. When I delete those NUL characters. It will definitely work.</p> <p>But I have more than 4000 xml files in the folder.I cannot delete those NUL one by one by my hands. My xml is encoded by utf-8. Is there any easy way to avoid those NUL characters? Or what kind of easy solution can delete those NUL characters?</p> <p>Thanks!</p> <p>also:</p> <p><img src="https://i.stack.imgur.com/PF2fx.png" alt="enter image description here"></p> <p>This is the NUL character. I opened in notepad++</p>

    1. COBefore you go deleting the `nul` bytes wholesale you should try to find out why they're there. Is the file encoded in UCS-2 or UTF-16? It may be that you are using the wrong input encoding. Can you post a sample of the input file showing the `nul`s? How about a hex dump of the file showing the invalid characters?

    2. CO@Jim Garrison I extracted the file directly from website(bugzilla). Here's the header:<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE bugzilla SYSTEM "https://bugzilla.mozilla.org/page.cgi?id=bugzilla.dtd"> <bugzilla version="4.2.7+" urlbase="https://bugzilla.mozilla.org/" maintainer="bugzilla-admin@mozilla.org" >

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
