Parsing xml in jsp

Can any one say how to parse the xml file in jsp.
NOTE: To get certain elements or tags value only and not the to parse the whole document.
Is this is possible in DOM.
If so any sample papers are available.

  • How to parse xml in jsp

    hei evryone!!!
    I'm a newbie in java, i just wanna know how to parse an xml file in JSP wherein i could remove nodes / modify certain nodes on the xml.
    Any suggestions / codes/ ideas would be much appreciated

    On my jsp page the default screen would be the list of traders. The user of the said application has the option to make some changes on the list either, add more trader/s on the list , remove specified trader/s on the list or edit certain trader/s. Furthermore, the user can also cancel the changes he made by clicking the cancel button or commit the modification he made by clicking the save button. When the application altered something, the changes must be reflected on the front end right away, but not on the database yet. In doing so, I intend to have two xml files , (1) the original xml file that is send to a CmsServlet (the servlet code that does the database commit) and (2) the temporary xml file that the page loads, which is initially just a copy of the original xml file. So whenever changes made at the frontend the temporary file is also altered, and when the save button is clicked, the temporary file is copied to original xml file to send the changes on the CmsServlet. But when the application user withdraws the changes he made at the frontend by clicking the cancel button , the original xml file is then copied to temporary xml file to reload the page.
    The access/modification on the temporary xml file is done in default.jsp.

    Hi,
    Why would you like to parse the XML inside a JSP page? JSP are for rendering and not for parsing XML. The code to parse the XML should be put in an ordinary Java class instead.
    Parsing XML can be done in a number of ways...it all depends on what you want to do with the XML. Are you looking for XML -> Java Object then maybe you should look at XStream or JAXB.
    If you can tell me a little more about your use case maybe I can help you a little bit more.

  • Parse XML DOM

    I need to parse XML DOM in flash......
    server side script is sending one var "req" through that XML
    DOM
    And after parsing that XML DOM i'll get a XML again from
    which i need to parse the path to load an image

    JSTL has an <x:parse> element, doesn't it? At any rate "I need JSP code" sounds very much like a JSP question to me. There's a JSP forum.

  • Best way to create, modify, XML with JSP ?  HELP

    Hi friends,
    As i am new to XML,
    I know there are two APIs used for XML processing, i want to know as a begineer level, which API
    is easy and good to implement XML with JSP.
    1) SAX
    2) DOM
    i want to make a log file in XML, so on web page it will be displayed on HTML form through XSL.
    Since there is good tutorial on http://www.w3schools.com/dom
    but i think its HTML dom
    I want XML procession through JAVA CODE , what should i use ? and give some good tutorials on XML DOM
    that is used with JAVA / JSP.
    HELP.
    Edited by: Ghanshyam on Sep 19, 2007 3:24 PM

    Well what i think is you gonna checkout with your requirements before implementing any of the popular XML parsing mechnisms.
    If you are intrested in faster processing @sacrifising a gud amount of your Memory,DOM is the one which you are looking for.
    If you are instrested in Managing your memory and but if you are ok with sacrifising speed SAX is the best solution.it works on what is called a push technology.
    and if you think either way you might have to look towards a pull parser which is StAX (Streaming API for XML Parsing)
    it'd be a gr8 idea if you can go through the below article which explians about each of the parsing mechanisms
    http://www.stylusstudio.com/xml/parser.html#*
    coming back to helpful resources as far java is concern checkout the below link which might be of some help.
    and the main thing is that all of these parser there is a defined specification you might find implementations of different vendors on this.
    eg:Sun Provides one with JDK itself,same as IBM provides one,oracle does the same & so on...
    your first task would be to focus on one such implementation which can cater your requirements.

  • How to Pass values from XML to JSP??? Urgent Please Help me

    Hi guys,
    I am new to XML, I want to pass values from XML to JSP. I have a xml file with attributes, I should send this values to a JSP file. How is it??? Please Help guys.... its very urgent. Please send me how to do it with an example or atleast any urls related that....
    Looking for ur favourable reply.
    Thanks in advance,
    Sridhar

    in a servlet :
    parse your xml file (see how at the end of the post) and
    put the values you want in the request attributes
    request.setAttribute("value1", value1);
    ...redirect to the jsp
    in the JSP:
    get the wanted attributes:
    String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

  • Creating XML using JSP

    Hi I want to create a xml using JSP For eg I want to create a report
              and I want to take all the data required for the report from the user
              and want to put all the information in a session and whenever a user
              wants to see the html output I should be able to parse the xml file
              and show it to user.
              I know it is doable but I am confused about storing the data in
              session and concerting that data into XML file any help would be
              great.
              Thanks,
              Preeti
              

    Sounds like you might want to look at XML data binding. Something like JAXB
              or Castor can create an object that can be turned into XML by merely calling
              a single method and probably streamed to Xalan or whatever to create HTML.
              However, don't quote me on this - I am having enough troubles with trying to
              get the compiled Objects to be as I wish. Basically, they both take your
              DTD with an extra file that defines the types to be used in the classes -
              i.e. instead of string int might be used - and which tags to turn into
              classes and general information such as this about the output of your
              classes. You then simply call Unmarshal (for both castor and JAXB) and it
              loads the file from the selected input stream into the created object, you
              edit the object, what ever - store it on the server... and call Marshal to
              get back the xml... as this is all using streams it could be passed to Xalan
              for processing i think...
              Hope I've helped, and answered your question a little!

  • RE: [iPlanet-JATO] Parse error in JSP parser in IAS6

    Hi Todd,
    removing the defaultValue="" attribute works.
    I have not got around to testing the SP3.
    BTW. The reason the default value tag was added was to stop Null pointer
    exceptions being thrown in the
    HrefTag.beginDisplay().
    buffer.append("?")
    .append(field.getQualifiedName()) // "FooHref"
    .append("=")
    .append(URLEncoder.encode(value.toString())); // "/foo"
    If you don't explicitly add a defaultValue="" to the jsp HREF tag ,
    HrefTag.getDefaultValue() returns null.
    Our hack was to add the following in HrefTag.java.
    if (value==null)
    value=getDefaultValue();
    //===========================
    //IP6 ADDED THE FOLLOWING LINE
    value = (value== null? "":value);
    //============================
    Is that pheasible work-around ? This eliminates the need to add
    defaultValue="" to all HREF tags.
    Also, I might as well point another behavior that we encountered with HREFS.
    In ND, if a HREF's display Field was bound to a column in DataObject and the
    particular record had no value, no URL would be rendered on the page.
    The HTML would look something like this( from memory ):
    <A
    HREF="../AppName/PgMsgMain.hrfSubject_onWebEvent(hrfSubject).994226335140? +
    ND URL STUFF"></A>
    In JATO by default a url get displayed with "null" as the link. ie.
    <a href="../AppName/PgMsgMain?PgMsgMain.hrfSubject= + URL STUFF">null</a>
    Our hack was modify the HrefTag.doEndTag method to not append "null" to the
    buffer.
    if (displayed)
    buffer.append(getBodyContent().getString().equals("null")? "":
    getBodyContent().getString()))
    // IP6 HACK buffer.append(getBodyContent().getString())
    .append("</a>");
    writeOutput(fireEndDisplayEvent(buffer.toString()));
    Is there a better way to do this?
    thanks

    Hey Kostas--
    I personally haven't seen this kind of error. Have you tried simplifying
    the expression inside the href tag? For example:
    <% Object foo =
    viewBean.getRptAssignmentMatch().getvwAssignmentMatchModel().getValue(
    vwAssignmentMatchModel.FIELD_ASSIGNMENT_ASSIGNMENT_ID);
    %>
    <jato:href name="hrefASSIGNMENT_ASSIGNMENT_ID" fireDisplayEvents="true">
    <%= foo %>
    </jato:href>
    Also, is there a different version you could upgrade to? iAS SP3 includes
    the Jasper compiler from Tomcat, which should behave quite differently.

    Script to parse XML data into Oracle DB

  • LO Error 26005 Failed to parse XML

    Good Afternoon,
    I currently have an Xcelsius document that is attached to a Crystal Report that is in Infoview.  I have it connected by using Live Office.  The Crystal report basically contains a cross tab of data and is run nightly in our system.  I bring back the data into Excel in order to build an Xcelsius document off of it.  I havent' been using the Live Office piece all that much until recently therefore please excuse my ignorance.  I setup my data connection as a Live Office connection.  My server connection seems to be correct:
    http://WHGCRYSTAL3:8080/dswsbobje/services/session
    However, when I try to refresh the document, I get the following error:
    soapenv:Server.generalException: Failed to parse XML. (LO 26005)
    Any ideas as to what this could be?  I have Crystal Xcelsius Enterprise 2008.  The version is 5.0.0.99 and the build number is 12,0,0,121.  I think I am all updated on service packs but I could  be wrong.  Any help is appreciated.

    I downloaded all of the service packs and fixes and now I am up to date.  I am still getting the error with an additional error.   This is what is says:
    Failed to parse XML. (LO 26005) (LO 26000)
    Any other ideas as to why this is happening?

    1. your code does not compile (in your main method you try to create an instance of a class which does not exist).
    2. your XML document is not well formed.
    +[Fatal Error] test.xml:34:74: The content of elements must consist of well-formed character data or markup.+
    org.xml.sax.SAXParseException: The content of elements must consist of well-formed character data or markup.
    Maybe there are other problems but you can start by fixing these.

  • Parse XML in a java stored proc

    I am trying to parse an xml document in a java stored procedure. Just following my nose, I have developed a stored proc that works fine in development (outside the database using JRE 1.4.1) using the Xerces 2.5 parser. But, after having transferred the xerces xercesImpl.jar, xmlapis.jar, and my implementation class into oracle using loadjava when I call my stored proc the code throws an exception trying to build the document with an error like:
    NoClassDef exception org.apache.xerces.jaxp.DocumentFactoryBuilderImpl
    My Code looks like this:
    import java.io.IOException;
    import javax.xml.parsers.DocumentBuilder;
    import javax.xml.parsers.DocumentBuilderFactory;
    import javax.xml.parsers.FactoryConfigurationError;
    import javax.xml.parsers.ParserConfigurationException;
    import org.w3c.dom.Document;
    import org.xml.sax.SAXException;
    InputStream is = getXMLAsInputStream(xml);
    try {
    DocumentBuilderFactory factory =
    DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document document = builder.parse( is );
    ... parse the document ....
    catch (FactoryConfigurationError e) {
    // unable to get a document builder factory
    The exception caught is a FactoryConfigurtionError.
    I'm not particularly attached to xerces, I'm really just looking for a way to parse XML inside my java stored proc, so any help to solve my problem, or an alternative suggestion will be greatly appreciated.
    thanks
    Dale

    I looked again and sure enough the xerces implementation classes were missing. I had run a .cmd file containing these two lines, but it looks like only the first one ran...
    loadjava -u ncc/xyz@usd -v -r M:\Database\JavaGeocode\Xerces2_5_0\xml-apis.jar
    loadjava -u ncc/xyz@usd -v -r M:\Database\JavaGeocode\Xerces2_5_0\xercesImpl.jar
    Now I've got everything working fine with Xerces!

    The reason for the error is the xquery is not able to find the values in the input... Check the input and namespaces...

  • How do you store parsed XML data in an array

    Hi, i am trying to complete a small program which implements the SAX parser to parse an XML file. My problem is that i am writing a custom class to store the parsed data into an array, and then make the array available to the main program via a simple method which returns the array. I know this must be very simple to do, but i seem to have developed a mental block with this part of the program. I can parse the data and print all the elements to the screen, but i just cant figure out how to store all the data elements into the array. I will post the class which is supposed to do this, and ask anyone out there if they know what i'm doing wrong, and also, if there is a more effeicient way of achieving this ( i expect there definitely is!! but i have never used the SAX parser before and am getting confused by the API docs on it!!) Any help very much appreciated.
    Here is my attempt at coding the class to handle the parsed XML data
    class Sink extends org.xml.sax.helpers.DefaultHandler
         implements org.xml.sax.ContentHandler{
    Customer[] customers = new Customer[20];
         int count = 1;
         int x = 0;
         int tagCount = 0;
         String name;
    String custID;
         String username;
         String address;
         String phoneNum;
    public void startElement(String uri, String localName, String rawName, final org.xml.sax.Attributes attributes)throws org.xml.sax.SAXException{
    //count the number of <name> tags in the XML file
         if(rawName.equals("name")){
              tagCount++;
    public void characters(char[] ch, int start, int len){
    //get the current string
         String text = new String(ch, start, len);
         String text1 = text.trim();
    //there are 5 elements for each customer found in the XML file so when the count reaches 6
    // i reset this to 1
         if(count == 6){
         count = count - 5;
         if(text1.length()>0 && count == 1){
              name = text1;
              System.out.println(name);
              }else{
         if(text1.length()>0 && count == 2){
              custID = text1;
              System.out.println(custID);
                   }else{
                   if(text1.length()>0 && count == 3){
                   username = text1;
                   System.out.println(username);
                   }else{
                        if(text1.length()>0 && count == 4){
                        address = text1;
                        System.out.println(address);
                        }else{
                        if(text1.length()>0 && count == 5){
                             phoneNum = text1;
                             System.out.println(phoneNum);
                             //add data to the customer array
                             customers[x] = new Customer(name, custID, username, address, phoneNum);
    // increment the array index counter
                        x = x+1;
                        }//end of if
                        }//end else
                        }//end else
                   }//end else
              }//end else
    }//end of characters method
    public void endDocument(){
         System.out.println("There are " + tagCount +
         " <name> elements.");
    }//end of class Sink
    Before the end of this class i also need to make the array available to the calling program!!
    Any help would be much appreciated
    Thanks
    Iain

    Ok, yer going about this all the wrong way. You shouldn't have to maintain a count of all the elements. Basically you are locking yourself into the XML tags not only all being there but are assuming they are all in the same order. What you should do is in your characters() method, put all of the characters into a string buffer. Then, in endElement() (which you dont use btw, you should) you grab the information that is in the string buffer and store it into your Customer object depending on what the tagName is.
    Also, you should probably use a List to store all the Customer objects and not an single array, it's more dynamic and you arent locked into a set number of Customers.
    I wont do it all for you, but I'll give you a good outline to use.
    public class CustomerHandler extends DefaultHandler {
        private java.util.List customerList;  // List of Customer objects
        private java.util.StringBuffer buf;   // StringBuffer to store the string of characters between the start and end tags
        private Customer customer;  // Customer object that is initialized with each entry.
        public CustomerHandler() {
            customerList = new java.util.ArrayList();   // Initialize the List
            buf = new java.util.StringBuffer();   // Initialize the string buffer
        //  Make your customer list available to other classes
        public java.util.List getCustomerList() {
            return customerList;
        public void startElement(String nsURI, String sName, String tagName, Attributes attributes) throws SAXException {
            // Clear the String Buffer
            //  If the tagName is "Customer" then create a new Customer object
        public void characters(char[] ch, int start, int length) {
            //  append the characters into the string buffer
        public void endElement(String nsURI, String sName, String tagName) throws SAXException {
            // If the tagName is "Customer" add your customer object to the List
            // Place the data from the String Buffer into a String
            //  Depending on the tagName, call the appropriate set method on your customer object
    }

      builder = factory.newDocumentBuilder();
      domDocument = builder.parse(is); // this line creates an exception
    catch (Exception e)
      System.out.println(e);
    This code works fine from an applet on windows. On linux, the error message is:
    java.security.AccessControlException: access denied (java.util.PropertyPermission entityExpansionLimit read)
    I've tried both JRE 1.4.0_04 and 1.4.1_03
    Thanks!
    Q

    There's another posting about this same problem (platform unspecified), but the same error message. I was also having this problem (Windows 1.4.03) and swithced back to 1.4.01 and the problem went away. In the future, I may sign my applets to get a more generous security policy. But, I'm sure it'll be a lot of work (vs. a line of code somewhere).
