I have to write an PL/SQL function where I can read all the data in the XML-file (see attach).
In this XML there is a BLOB stored (base64 - stream -> that contains always a MSWORD document).
1) how can I extract this BLOB + the other data in the XML and save this data in a ORACLE table?
2) how can I decode this BLOB and save this MSWORD-document to a fileserver?

First extract your data as CLOB (as it's character based)...

    Can any one help me.
    thanks
    Raghu.

    Raghuvasa,
    Get the XML file data into an XML variable in your code, say var jukebox: xml. Then do
    combo.dataProvider = jukebox.song.url
    or as a shortcut
    combo.dataProvider = jukebox.descendants("url")
    The latter will pull out elements with tag name url at any depth in the xml structure, so sometimes you have to be careful, but in your case there should be no problem.

  • How to read data in correct format from EXCEL file into an internal table??

    Hi Experts,
    My requirement is to upload data from an excel file on presentation server into an internal table on <b>SRM</b> server.
    I used 'GUI_UPLOAD' function module to achieve the same but all the the data is getting uploaded in # only.I had set in the 'HAS_FIELD_SEPARATOR' to 'X' to overcome this problem.
    But all the efforts are in vain. The function module 'ALSM_EXCEL_TO_INTERNAL_TABLE' doesn't exist on SRM Server and I am not getting any other function module having similar functionality available on SRM server.
    I have written the following code:-

    I know if we use UTL_FILE.get_line we can read the whole line...but i need to read the tab separated value separately.....If it's a text file then UTL_FILE will only allow you to read it a line at a time. It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
    If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

  • How to retrieve image from XML  file

    Hi All,
    I am new to XML. So any best guidance is appreciated.
    The application requirement is to display image retrived from uploaded xml file in file upload section of our application. And store that image in database.
    In my XML file , images & strings & numbers & booleans are there . I am able to save everything in database except images .
    I am using JSF, Seam & Hibernate combination. In my Hibernate entity class i took BLOB datatype for image.
    I am using following tags in my Xhtml file to display image
    <s:graphicImage value="#{hibernateentitybean.picBlobtype}" height="200" width="200">
    <s:transformImageSize width="200" height="200" />
    <s:transformImageType contentType="image/jpeg"/>
    But image is not displayed in Xhtml file
    I am using org.w3c.dom.Document for retrieving node name & corresponding value in that node in XML file.
    I am getting code like below for Image when i am logging all values from XML files in my bean class .
    x0lGQRQAAAABAAAAAAAAAFJHAQARAAAAVwBhAHQAZQByACAAbABpAGwAaQBlAHMALgBqAHAAZwAAAP/Y/+AAEEpGSUYAAQIBAGAAYAAA/+0YLl
    I want to convert this value to image. So i can convert image to bytes and store in BLOB.
    Can anyone guide me ? or any other approach .
    Thanks in advance for any reply.

  • Live Streaming from Video File

    Hi everyone,,, im newbie in programming streaming video with flash....ater reading documentations i tried the instructions on doc, i got a question that i've not been solved. How to make a "live streaming" from "video file". It likes a live streaming from camera but it uses video file  as the source.... many thanks

    Do you mean you have video file but you want to publish it as live stream , am i right? If yes following is the solution, but before that let me clarify you will need server to do it , i mean there is no way Flash client (i.e. .swf file running in Flash Player) can publish file from local disk.
    Now let me tell you how to do it from server:
    Place your video file under "streams" folder of your application i.e. say "myVideo.flv" under  <FMS root>/applications/myApp/streams/_definst_
    Now write following code in your main.asc file (this file would be under <FMS root>/applications/myApp )
    var mystream;
    application.onAppStart = function(){
         mystream = Stream.get("livestream");
         mystream.play("myVideo",0,-1,true);
    This will publish "myVideo" file as live stream under name of "livestream". Client would have to subscriber using NetStream and
    use ns.play("livestream",-1,-1)
    You might have to write some extra code if you want to loop same file else once play of recorded file gets over , live publish will automatically stop.
    let me know if this solves your problem

    Hi,
    I want to load a sales order from XML  file. How can I do ? how can i create the sales order?
    what are the necessary  setting for  create the sales orders.
    with Regards,
    Prakesh.

    Three options come to my mind.
    Option 1: Use SAP transaction SXDA_TOOLS (Object Type BUS2032), Program Type (BAPI) and Program (CREATEFROMDAT2).
    Option 2: Use SAP transaction SXDA_TOOLS (Object Type BUS2032), Program Type (DINP) and Program (RVINVB10).
    Option 3: Translate the xml to IDoc so that ORDER04 / ORDER05 Idoc can be used to create Sales order (WEDI transaction).

  • Reading and writing to and from a file to a form

    Hi there
    I would like somebody to send me a code example,
    showing me how to reading records from a file to a form,
    and writing records to the same file from the same form.
    I know that I have to use sycronize, but I just have not been
    successful. I can constract forms, go from form to a form,
    do buttons, do text fields. I can even read and write from and
    to files. However I cannot do is write from a file to a form and
    from a form to a file.
    could somebody please explain how this done, and could you
    please give me a code example. All the books seem to either
    deal with forms or with files. None seem to combine both.
    I am sure it is very ease to do if ONLY I knew how!!!
    thank you very much in advance for you help.

    I understand that code and I have used it before, however thanks for
    trying to help me, it is really appreciated. However, that is not my
    problem. I can read and write from a file to the console and vice versa.
    what I cannot do, no matter how hard I try, is to write from a file, and
    output it in.
    I will tell you how far I have got.

    what I am trying to do is for the New client form to be able to read and write from and to a file, and display the info.
    I am working in JBuilder3, a bit out of date I know, but it is the best I can do. Any Ideas how to do this.

  • How to remove Unicode from XML file

    I get following error when unmarshal xml:
    [java] org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x15) was found in the element content of the document.
    Anyone know how to remove Unicode from xml file? Can I remove the unicode by rebuild the file?
    Thanks

    These sort of error usually occur when you're using a different character encoding to read the file than the one you wrote it with. Perhaps if you were to post the problem section of the file and/or the code that created it in the first place.
