How to Read and Generate XML file from java code.

hi guys,
how to read the xml file (Condition :we know only DTD or Shema only).
How to Generate the new xml file ?(using Shema )
And one more how directly Generate the xml from DB?
Pleas with code or any URL

Using XMLbeans you can generate Java objects from an XSD schema (perhaps DTDs aswell)
Then you can create an instance of the Document object and ask it to write itself.
This will create an XML document complient to the schema.
XMLBeans generates a "type" safe DOM where you can only ever have a structure compilent to you schema.

Procedure for read/write an XML-File using UCCX9

Hi Team!
Is there someone who can explain me the procedure of reading/writing an XML-File using Cisco UCCX Rel. 9.0?
In the last couple of days I did a lot of research on the partner community as well as reading the CRS-Editor-PDFs.
But I can’t find a solution.
There are some templates available but they all didn’t seem to work.
I have two xml-files, both uploaded to “Document Management\en_us\”.
The script itself is attached to this posting.
I build that my script according to a sample script I found in the community.
From my point of view I have configured my script exactly like the sample script.
But it still doesn’t work.
I am especially interested in where to store the the appropriate files.
I would be very happy if there is someone who can explain me, what’s wrong there.
Many thanks in advance.
Kind regards
Michael

I'm experiencing the same issue [reading XML causes errors that say things from "no such file" to some odd Java exception.] I'm able to use a template XML file and after authenticating a user, transform the template into a proper XML file and then successfully save it to the en_US Doc Repository with updated values.
However, no matter what I've tried or who I've asked, the READ on the XML file so that I can actually script something that does some routing based on the value of the XML file created in my first script? Ultra fail.
I've even worked with three separate TAC IPCC engineers who were able to reproduce the issue in their test environment, but they were unable to assist. Eventually, whe pressed, I received this response from the last IPCC engineer.:
"Hello Brad,
Yes I know what I provided you with is what you already have achieved and this missing step is precisely what you need: how to setup the script to check the status and value of this XML document and then decide routing according to the state. But unfortunately this is what I found internally. The other resources are the ones you already know: support forums, scripting guides. The other resource with suggest to customer looking for script assistance is the Cisco Account Manager of your company, they know where to get the resources for such issues. Then again as I mentioned before on our phone conversation TAC does not support scripting but certainly if I find something else on my side I will let you know for sure."
I would do ponderous cartwheels of joy if someone who has this working in version 9.x [9.0.2 specifically] could share the deep magic.

How Do I write an XML file using Java?

Hello there!! to everyone reading my post.
I have this project I need to do, and I have no clue where to start, I was wondering if you guys could help me out.
I need to know how to write an XML file using a Java Program, but without using a Third party library.... just using java native APIs.
I will probably take the values to construct the file from a form.
I will certainly appreciate if you could post some sample code for me.
Thank you very much in advance..

Hello there!,
I have some doubts about the Tutorial I am currently reading. correct me If I'm wrong, but the section "Write a simple XML file" teaches you how to do so using a text editor. I need to create my XML file from a running Java Program written by myself, that takes the values to build it from some variables.
If I'm totally wrong about what I'm saying, could you please point me to where I can find the information of how to do what I'm asking for, inside the tutorial.
Thank you very much,...
sincerely.

How to read/write a binary file from/to a table with BLOB column

I have create a table with a column of data type BLOB.
I can read/write an IMAGE file from/to the column of the table using:
READ_IMAGE_FILE
WRITE_IMAGE_FILE
How can I do the same for other binary files, e.g. aaaa.zip?

There is a package procedure dbms_lob.readblobfromfile to read BLOB's from file.
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#sthref3583
To write a BLOB to file you can use a Java procedure (pre Oracle 9i R2) or utl_file.put_raw (there is no dbms_lob.writelobtofile).

Hi,
there are two examples in Help >> Example Finder >> Fundamentals >> File Input and Output. One is Write Data to XML File and the other is Red Data from XML File. The first will write it and the second will read it back.
I expanded th example with the String data and the value provided in your post and it work even with the '/' in the data.Message Edited by waldemar.hersacher on 04-06-2005 11:23 PM

How to read an external XML file in a indesign Plugin?

Hi All,
Can you please guide in reading an external XML file in a indesign Plugin in MAC system. I am an windows user.We are using this file for reading some inputs.
Thanks,
Daniel

Hello Daniel,
I am uncertain about the actual question. If you are developing a plug-in or otherwise interfacing with the guts of ID, I suggest asking the question in the SDK forum:
InDesign SDK Forum
Otherwise, what is it you are wanting to know concerning importing XML into InDesign?

How to read from a xml file(in String format) using a java program

How to read a incorrect XML file using file adapter

Hi',
I have a XML file which is incorrect,
example
<?xml version='1.0' encoding='UTF'?>
<emp>
<empid>100</empid>
<empname123>yatan</empname>
</emp>
now we can see that the XML data *<empname123>yatan</empname>* is incorrect,
so if we have to read this type of XML in BPEL is it possible to read it or can we read it with some work around
I have tried one way to achieve this,
I read this XML with file adapter opaque read operation, and inside the BPEL process used Base64Decoder (Java embedding) to decode the
opaque data to XML, it works to some extend. I am able to see the only the data like,
100 yatan
If I read a correct XML with same approach the data is a complete XML like,
<?xml version='1.0' encoding='UTF-8' ?>
<emp>
<empid>100</empid>
<empname>yatan</empname>
</emp>
can some one advice me how to achieve this, or some one has done this before
thanks
Yatan

What initially I have thought is,
once a incorrect file comes in this failed directory, some BPEL process should get invoked and feed the data to user, for this I thought of designing a BPEL process which will poll this failed directory, so for this we will need a empty BPEL process which will pick the file and then pass the data, the issue is I need to use here a opaque read and I dont know how to convert back the opaque (faulty XML) back to string.
I have already tried to convert the opaque to XML using java embedding but for faulted XML only the data comes back in the form of string, where as need the complete XML back, can you suggest how to do this.
thanks
Yatan

HOw to update XML file residing in DAM by component JSP in run-time?

i have made a component which reads xml file residing in DAM.
Content Author can fill some values in dialog of this component, as soon as author provide the values,i have to update these values in XML file and component reloadsby reading the updated xml file.
i am trying to achieve this by making object of XML file and giving it's path., but i ma unable to access the XML file.
Can anyone help me out to how to update XML file by component JSP in run-time?

Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT?
XSLT approach: check these online tutorial
http://www.xml.com/pub/a/2000/08/02/xslt/index.html
http://www.xml.com/pub/a/2000/06/07/transforming/index.html
ABAP approach:
for example you have the xml (original) in a string called say xml_out .
data: l_xml type ref to cl_xml_document ,
        node type ref to if_ixml_node .
create object l_xml.
call method l_xml->parse_string
exporting
    stream = xml_out.
node = l_xml->find_node(
    name   = 'IDENTITY'
   ROOT   = ROOT
l_xml->set_attribute(
    name    = 'Name'
    value   = 'Charles'
    node    = node
(the above example reads the element IDENTITY and sets attribute name/value to the same)
like wise you can add new elements starting from IDENTITY using various methods available in class CL_XML_DOCUMENT
so how do I access the XML file in order to update it?
you have already read this XML into a ABAP variable right?
Sorry couldnt understand your whole process, why do you need to read local XML file?

Writting a XML file from a DOM with the reference to a DTD

Hi everyone,
how can I write a XML file, that has a reference to a DTD like:
<!DOCTYPE testdoc SYSTEM "testdoc.dtd">
I have a DOM that contains my XML-Data and I want to have this line in the XML File. I'm using a Transformer to write this XML stuff in the file.
Does anyone has an idea?
Thanks in advance

Read data from xml files and populate internal table

Hi.
How to read data from xml files into internal tables?
Can u tell me the classes and methods to read xml data..
Can u explain it with a sample program...

<pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
DATA l_o_error TYPE REF TO cx_root.
DATA: filename type string ,
             xmldata type xstring .
DATA: mr      TYPE REF TO if_mr_api.
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
WRITE xmldata.
TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.
LOOP AT itab_accontextdir INTO struct_accontextdir.
    WRITE: / struct_accontextdir-context_id,
           struct_accontextdir-context_name,
           struct_accontextdir-context_type.
    NEW-LINE.
    ENDLOOP.</pre>
<br/>
Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
    Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
      CALL TRANSFORMATION id
        SOURCE shiv = t_internal_tab
        RESULT XML xml.
    CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
<br/>
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!

How to update XML file using XSLT

Hi there,
I have a "small" issue with exporting data to an XML file using XSLT.
A two steps process is needed to import data from a non-hierarchical XML file into ABAP, change the data, and then update the XML file with new values. The problem is not trivial, since the format of the XML file is a complex one: there are many interdependent elements on the same level, pointing to each other by using id and ref attributes. Based on these values the data can be read and written into an internal table. I use XSLT and XPath for that. So the inbound process is done and seems to work correctly. I have to mention that the file contains much more data than I need. I am working only with a small part of it.
Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT? I can pass only the internal table to the transformation, so how do I access the XML file in order to update it? I have tried to use the <B>xsl:document()</B> function to access the content of the file store locally on my PC, but it fails each time by throwing and URI exception. I have tried the absolute path without any addition and the path with the file:/// addition. Same result. Please advise.
Many thanks,
Ferenc
P.S. Please provide me with links only if they are relevant for this very matter. I will not give points for irrelevant postings...
