Link multiple XML files stored in oracle database

Link multiple XML files
Can any one give some code example regarding my issue:
If I have for example file1.xml stored in one relational table and another file2.xml stored in another table ….etc
And I want to put link and reference which will make me able to link these files and make query or insert…etc
May be I need to use Xlink, Xpoiner or Xinclude . But if this is the solution to this problem please can you give a simple example that will help to understand the solution especially that I want to develop my project in oracle and I will register xml schema to insert the xml files in the database
Thanks lots and I am waiting for your solution

no answer for my question
is this thread is a write place or I have to move my query to another part of the forum
thanks

Reading an XML file stored in Oracle

Is it possible to read an xml file stored in Oracle via Oracle methods?

If by "read" you mean "read as text", then you can just select the document as a CLOB and return it.
If by "read" you mean "read and parse", then you can use the Oracle XML Parser for PL/SQL to parse the CLOB into a DOM structure.
My Building Oracle XML Applications book has lots of examples of doing this, but especially in chapter 5, "Processing XML with PL/SQL".

Loading XML files to an oracle database

Hi,
I have some users who would like to send me XML files that I would need to parse and load into multiple tables in my Oracle database. Since I'm new to XML, I'd like to know if XMK DB is the technology that I need to explore in order to do this, and if so, are there any white papers or articles out there that might get me started.
I have previously loaded data into my databases via text files that I parsed using text_io, I'm not sure if there is a significant advantage in using XML. This data load is going to be on an regular basis and I would like to validate the data the data before loading this.
Any help or guidance would be greatly appreciated.
Thanks.
Azeem.

XML is becoming the defacto method of exchanging data between systems due to it's self describing nature. XML DB is the preferred way of processing XML in Oracle 9iR2 and later. The banner for this forum provides links to the XML DB OTN pages where you can find lots of information related to using XML DB.

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,
    created_dt                     DATE NOT NULL,
    case_id                        NUMBER NOT NULL,
    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.

Getting attributes from a XML File, stored in Oracle

This file I have stored in Oracle as table of XML Type.
Now I have build a little Java Programm, that displays the XML File like the File structure in the Windows Explorer.
I want, when I choose a file in the File structure, that the ID3 Informations like album artist a.s.o. can be displayed. My problem is, I couldn't get these informations e.g. in an array from the database. Any suggestions how I could realize this in Java?
Thx for any comments
Max

Try this:
select extract(xmltypefieldname, '//xpath/field@attribute').getStringVal() from yourtable where yourwhereclause
You can also select elements that match certain attributes by using a predicate such as field[@attr = myval][@attr2 = myval2]...
Hope this helps.

How to extract the contents of ZIP file stored in oracle database column ?

The file is in ZIP format and it is stored in BLOB databse column . The contents of file is in binary format .
How to extract those contents from file and thus creating the same ZIP file as output in ODI ?
Thanks

Perhaps you can something like what is described in the support note "How To Load A PDF File Or Other Binary Files To a BLOB Column From ODI (Doc ID 1412753.1)"

Oracle reports to display PDF/Excel files stored in the Database

can we use Oracle reports to view/display PDF/Excel files stored in the Database? Thanks Lalitha

A document stored in the database can be easily retrieved in or via the browser using mod_plsql. Simplified:
select content, mime_type
into v_blob, v_mime_type
from ...
owa_util.mime_header(nvl(v_mimetype,'application/octet'),false);
htp.p('Content-length: ' || dbms_lob.getlength(v_blob));
owa_util.http_header_close;
wpg_docload.download_file(v_blob);So, the link in your report should point to this database procedure.

Need to store multiple xml files as each record in oracle table

Hi All,
I have a set of XML files (say 20 xml files). I need to store the enitire content of each file as a string into the oracle table.
Do we have any PL/SQL procedures which will do this job. I will pass the path of the directory to the procedure, so that it takes all the xml files and store it in the table.
After that i need to remove some tags of the xml. so it will be better if we store records as a string rather than of xmltype.
Please help in achieving this.
Thanks in Advance,

Hi Gyanchand,
I have wrote an article BizTalk Server 2010: Grouping
and Debatching/Splitting Inbound Messages (TypedPolled) from WCF-SQL Adapter which is for SQL, but yes same can be done with Oracle.
If grouping is not required then, you can overlook it and apply debatching only.

How to Merge multiple XML files in one file ( Env: XML Publisher 5.6.2)

All,
I have recently started working on XML publisher and have developed 3 reports in last 2 days using XML Publisher and integrating them with Concurrent programs.
This is a great tool.
I have got another requirement, where i need to use xml file generated by multiple run of same report with various parameters and then merge all xml file to a single report. Developing the whole custom process will take very long time and sure will have bugs in it. Instead i was thinking to use xml file generated by Oracle report itself.
Report "US Gross to net summary" generates xml output in standard output directory and then show output in PDF file. I have 7 such file generated for each payroll. I want to merge output of xml into a single xml so that i can create single report having data from all 7 xml files showing me All payroll output in a single report.
Can someone please guide me , how can i read xml file data from the output directory of a seeded concurrent program and how to manipulate data in it.
Thanks
Ankur

Hi Tim,
Thanks for replying. I have looked for "PDFBookBinder class" in xml publisher user guide for ver 5.6.2. I didn't get any reference of this text. Can you please guide me to a tutorial/link where i can get more information about this class.
Also, i originally thought of similar to your second logic, as my design basis. Oracle process generates the xml file in output directory which i can get. What i didn't get is how do i "pick them up and merge" using publisher. Also, is there way to do this merging process using pl/sql ? Can you please give little more information on your second approach.
My original plan of action is that i will create a report set in which i will call oracle seeded report for all 7 payrolls in a sequential manner. Then using the child requests of the report set i will get to 7 xml files generated by seeded oracle process. Then the piece i am not sure of , i will use those 7 files to generate a single xml file having payroll name as tree top for each output. Once single xml is ready, i can easily design a template and register the process to generate output as Excel.This process will not require me to actually change any data or do any calculation. It will only reformatting the feilds we see and abiity to see all 7 payroll at one time rather then entering these numbers manually into an excel to do analysis.
Please provide your feedback, if you think above plan is not feasible or need corrections.
Best Regards,
Ankur

Can Discoverer have link to display documents stored outside the database?

I posted a message some time ago called "Possible for Discoverer to display BLOB type documents stored in database?" and got great answer.
Now our customers are asking if it is possible, from Discoverer, to link somehow to a file stored outside the database on the Unix file system and get their computer to display it? Can anyone tell me if this is possible please?
The only thing I've seen in the documentation that may be related is in Oracle Business Intelligence Discoverer Configuration Guide, section 10.6 List of Discoverer user preferences. It says there that Discoverer preference ProtocolList can be set so that Discoverer hyperlinks can be set to use protocols such as telnet, but the default is HTTP, HTTPS, and FTP.
THank you in advance if you can help.
Regards,
Julie.

Hi Rod,
I have tried the second method: "create a Oracle directory pointing to the Unix directory containing the files". I have had success with it, but I'd be grateful if you could advise me if you would have done this the same way as described below:
I put two Word docs and two text docs called clob_test1.txt, clob_test2.txt, blob_test1.doc, blob_test2 in the Unix directory corresponding to an Oracle directory called 'EIF'. I thought an extrenal table was needed so that Discoverer would have an object to write a queruy against. So I created a file called lob_test_data.txt with the following contents:
1,01-JAN-2006,text/plain,clob_test1.txt
2,02-JAN-2006,text/plain,clob_test2.txt
3,01-JAN-2006,application/msword,blob_test1.doc
4,02-JAN-2006,application/msword,blob_test2.
THen I created an external table using the following DDL:
CREATE TABLE jum_temp_lob_tab (
file_id NUMBER(10),
date_content DATE,
mime_type VARCHAR2(100),
blob_content BLOB
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY EIF
ACCESS PARAMETERS
RECORDS DELIMITED BY NEWLINE
BADFILE EIF:'lob_tab_%a_%p.bad'
LOGFILE EIF:'lob_tab_%a_%p.log'
FIELDS TERMINATED BY ','
MISSING FIELD VALUES ARE NULL
file_id CHAR(10),
date_content CHAR(11) DATE_FORMAT DATE MASK "DD-MON-YYYY",
mime_type CHAR(100),
blob_filename CHAR(100)
COLUMN TRANSFORMS (blob_content FROM LOBFILE (blob_filename) FROM (EIF) BLOB)
LOCATION ('lob_test_data.txt')
PARALLEL 2
REJECT LIMIT UNLIMITED
then created a Discoverer End User Layer folder against this external table, and used exactly the same technique as we did for downloading the BLOB from the database table (creating a new folder item containing a URL calling a database procedure which calls the Oracle code to download the doc). THis worked, but sometimes my PC didn't seem to know that the Word docs were Word docs and it needed to launch Word. Other times it did manage to do this OK. It always displayed the two .txt files as HTML docs.
Just wondered if you'd be good enough to critique this approach.
THank you, Julie.

Best ways to view/display PDF/Excel files stored in the Database

What are best ways to display/view PDF/Excel files stored in the Database? thanks L

Thanks tom, sorry let me explain. Currently we have oracle forms screen, using webutil to store/view files into DB. client won't like the interface, they want us to make it more friendly, drag and drop if possible, load multiple files, as possible.. So I am exploring different ways to improve may be java (or jdev/any any other), different screen designs, different features for fileupload/download/view options.

Creating multiple XML files from Schema

We are extracting data from Oracle DB into XML using ODI. We are successful in generating the XML file, using command "create xmlfile <file name> from schema <Schema Name>, but the entire data comes in Single file.
Our database schema is relatively Huge and we would like to generate multiple XML files. We want to generate one file per particular number of records. Can anyone help to do this.

one solution i can think of is to use SQLX operator instead of dbms_xmlgen.
here is a sample example.
declare
l_xmltype xmltype;
l_deptno emp.deptno%type;
begin
for i in (select * from emp order by deptno)
loop
    select xmlconcat(
                xmlelement("ename", i.ename)
               ,xmlelement("sal", i.sal)
               ,xmlelement("detpno", i.deptno))
      into l_xmltype from dual;
    dbms_output.put_line(l_xmltype.GetClobVal());
end loop;
end;
/Now here you can open the query once, keep writing to the file till the deptno
is same, when the deptno changes, close the file and open a new file with new
deptno and start writing.
Note : in this way you will have to add the xmlprolog manually to each of the file which should not be an issue. after opening the file add the prolog string manually.
Hope this helps.
