The XML parsing

I get an XML from a URL and try to analyze, but his does not work. The xml code is like this:

HTML here

My code is as follows:

DocumentBuilderFactory dbf1 = DocumentBuilderFactory.newInstance();
                dbf1.setValidating(false);
                dbf1.setExpandEntityReferences(true);
                dbf1.setIgnoringComments(true);
                dbf1.setNamespaceAware(false);
                db = dbf1.newDocumentBuilder();
                try {
                    doc = db.parse(input);
                } catch (SAXException e) {}
                NodeList list = (NodeList) doc.getElementsByTagName("node1");
                System.out.println("VALUE:" + list.item(0).getFirstChild().getTextContent());

The System.out.println prints VALUE: null, while the name of the node of printing prints the correct value, and list.length is 1.

What's wrong? Could the HTML tags be spoil it?

Ugh... I removed the dbf1.setIgnoringComments (false); true and it works... Thank you

  • Could not create constants/controls/indicators from the XML parser

    Is there a reason I can't create a constant/control/indicator of the XML parser function ref (by right clicking)? I need to make the Subvi in build/read xml files, and it's really impossible without this ability.

    This bug has already been reported (CAR 357092) and should be corrected in the next service pack release. For now, here is a workaround:

    2. right click on the new terminal of indicator 'DOM Document Out' and select Create > command (or indicator).

    3. right click on the new indicator of control / and choose Select XML Parser Class. Then you can choose what class you need.

  • I get random failures to load a page with the XML parsing error: entity not defined using firefox 4

    This didn't happen with the version 3 x, nor with the previous v4. Using the arrow to the left and clicking on the previous page request usually works ok. It happens several times a day. Full error is

    XML parsing error: undefined entity

    I am also getting this error and have been able to understand that its caused by the Bandwidth_Meter_and_Diagnostics - 1.2.5.xpi. This deactivation seems to have stopped the error, but is a major nuisance.

  • The XML parsing problems

    I started with the sample of XML parsing and tried to get a simple user interface that loads buttons with the value of a child node (more later to go to a new screen and analyze another XML code).  When I analyze the XML code, I get the knots, but I don't get the values.  My example of XML is generated.

    Example of XML data:

    What information to post in the Windows Update forum

    Windows Update forum is one of the three forums that doesn't have different forums for different versions of Windows (Internet Explorer and the game are the others).  With this in mind, we ask that you postat LEAST the following information.  If you don't know how to find some of the information and then post what you can and let us know that you need help to find information.

    Minimum information to validate:
    Version of Windows and Service pack level. (Windows XP Home Edition, SP3; Vista Home Premium, SP1; Windows 7 Ultimate, etc...)
    Post also if you use 32-bit or the 64 bit version of Windows.

    Update the number of the last update installed before any problem.  If you do not know the number of update, then give the date that the update has been installed.  The number of updates update failed.

    Error code updates failed or if you think an update caused a blue screen, give the blue screen error codes.

    Other information to validate:
    Measures already taken to correct the problem and the results of the measures.

    If the question is never happened before with other updates.

    A few other useful parts are:
    What program antivirus you use, if it is up-to-date, and there has never been any other installed antivirus program.
    If your version of Windows has been upgraded from a previous version or if it came with (or clean installed with) the version you are currently using.

    You shouldn't have to join here.

    Solved...

    I analyzed using

    String _nodeName = node.getNodeName ();

    _nodeValue = doc. GetElementsByTagName (_nodeName). Item (0) .getFirstChild () .getNodeValue ();

    and his works fine.

  • XControls, XProblems, of XML parsing

    I use a motor of Action (functional overall) to keep a reference to a DOM Document, with several States to manipulate the document.  I call the engine action XControls on Init and Uninit VI, so that there are XML elements that are added/removed by the engine of the action when the XControl is added or deleted a VI.  I am able to add many copies of the XControl without problems.  Often I can go on adding and removing XControls several times.  Randomly, however, I get a 15 warning associated with the XML parser, indicating that the Document DOM resource is not valid.  From this moment, I'm more able to make changes to the document - I can view the XML associated with the DOM using XML Document to get, but am not able to manipulate it in any way.  It is as if the object or reference has corrupted.

    Y at - it a known bug related to this?  If I run the motor of action independent of the XControl I don't get this problem.  XControls tend to corrupt the references in external screw for the XControl?

    I'm using LabVIEW 8.6.  Thanks for any help.

    It turns out that it is not necessarily a bug.  The problem arises from the way LabVIEW automatically cleans references for the screws that are no longer active.  I called the overall functioning of the XControls in the Init and Uninit capacity live after the creation and deletion of multiple copies of one the XControl on my front, LabVIEW must have decided that I used is no longer the global functional and empty its references VI.

    To resolve this problem, I now initialize the functional overall in a hidden 'main' VI which runs as long as I have any XControls on the front panel.  The case put the functional overall in a calling tree remains active rather than one that is more sporadic, such as the call XControl VI tree.

    I can understand why there was a problem, given the unusual delivery XControls.

    Thanks for following, I hope this helps others when generating XControls - they are really not so bad once you get used to their strange behavior.
