XML with PL/SQL

i want to generate the XML document in tree
structure format by writing the Pl/sql

Use the xmlgen.getXML package/proceure. This comes with the Oracle SQl Utility (I believe) tool.

Validate xml with PL/SQL Parser

Hi,
i have an xml DTD into a VARCHAR2 variable and an xml document
into a CLOB, i'd like to know how to validate the xml with my
DTD using PL/SQL API for xml.
Sorry for my terrible english (i'm not english) :-)
Tank you.

Here's an example:
set serveroutput on
DECLARE
p xmlparser.parser;
d xmldom.DOMDocument;
dtd xmldom.DOMDocumentType;
v varchar2(32700);
good clob;
bad clob;
xml_parse_error exception;
pragma exception_init(xml_parse_error,-20100);
BEGIN
bad   := '<!DOCTYPE Department SYSTEM "test.dtd"><Deprtment/>';
good := '<!DOCTYPE Department
SYSTEM "test.dtd"><Department/>';
v := '<!ELEMENT Department EMPTY>';
p := xmlparser.newParser;
xmlparser.parseDTDBuffer(p,v,'Department');
xmlparser.setDoctype(p,xmlparser.getDoctype(p));
xmlparser.setValidationMode(p,TRUE);
xmlparser.parseClob(p,good);
xmlparser.parseClob(p,bad);
xmlparser.freeParser (p);
EXCEPTION
WHEN xml_parse_error THEN
     DBMS_OUTPUT.PUT_LINE(sqlerrm);
     xmlparser.freeParser (p);
END;

Create XML with PL/SQL

Hi,
What is the best way to create large XML in pl/sql?? and to read large XML from CLOB procedure parameter?????
Thanks

Use the internal XML-structures of the database, such as XMLType, XMLElement, XMLForrest. Have a look at the XMLDB-documentation.

Validating XML with PL/SQL parser

How can i validate a xml that is on a buffer with the grammar
stored in a BLOB column of o table? I'm using PL/SQL parser and
i can parse it correctly but i don't know how can i validate it
because my grammar is stored in DB.

You can't currently but this will be available in our next

XML Publisher Report with PL/SQL

Hi
Like to know how to develop the XML Publisher Report with PL/SQL, i did the following
1. created a pkg like as below
CREATE OR REPLACE PACKAGE BODY APPS.TEST_XMLTAG_PKG AS
PROCEDURE main (errbuf OUT VARCHAR2,
retcode OUT NUMBER
) IS
BEGIN
DECLARE
ctx DBMS_XMLGEN.ctxHandle;
xml CLOB;
BEGIN
ctx := dbms_xmlgen.newcontext('select * from scott.emp');
dbms_xmlgen.setrowtag(ctx, 'MY-ROW-START-HERE');
xml := dbms_xmlgen.getxml(ctx);
dbms_output.put_line(xml);
Fnd_file.put_line (fnd_file.LOG, XML);
END;
END;
END TEST_XMLTAG_PKG;
this pkg produces the output with xml tag in the view log.
I have registered the conc program & xml rtf but it does not produce the output in PDF, , I am not able to get the xml tag when i click the Diagnostics --> View XML.
can you please let me know the next steps involved.
Regards
Yram

I think the problem is because there is no begin and end tag. save the xml from the logfile and open with xml editor or IE.. then you will see the problem.
add Begin and end tag...then you should be fine.. i.e
fnd_file.put_line(fnd_file.output,'<EMP_DATA>'); -- begin Tag
tx := dbms_xmlgen.newcontext('select * from scott.emp');
dbms_xmlgen.setrowtag(ctx, 'MY-ROW-START-HERE');
xml := dbms_xmlgen.getxml(ctx);
dbms_output.put_line(xml);
Fnd_file.put_line (fnd_file.LOG, XML);
fnd_file.put_line(fnd_file.output,'</EMP_DATA>'); -- End Tag
Hope this helps..>Good Luck

Create document with PL/SQL xml parser

Hello,
I'm trying to create a document with PL/SQL package xmldom on 8.1.7 and write to a file.
The problem is that my file is empty when it's created.
Can anyone send me an example of this simple problem or fullfill my example so it's works.
As you understand I'm new in using XML. :)
My example is:
declare
doc xmldom.DOMDocument;
n xmldom.DOMNode;
e xmldom.domelement;
t xmldom.domtext;
begin
doc := xmldom.newdomdocument;
t := xmldom.createtextnode(doc, 'ROOT');
n := xmldom.makenode(t);
doc := xmldom.makedocument(n);
xmldom.writetofile(doc, 'd:\orant\xdk\plsql\demo\test.xml');
end;
Regards
Hekan

Your problem may be memory for the JavaVM. Remember, the PL/SQL
parser uses the Java XML Parser APIs which run in a VM instance.
Are you running Oracle 8i? If you are you can access our Java
XML parser loaded in 8i's VM directly from your PL/SQL code.
That is in fact how our PL/SQL Parser does it.
Finally, we have no experience loading other XML Parsers into
Oracle.

Oracle SQL - Extracting clob value from XML with repeating nodes

Hi All,
I am attempting to run SQL on a table (called test_xml with a column xml_data [data type xmltype]). The column contains xml with repeating nodes (description). The following statement runs successfully when the node contains data of a non clob size:
SELECT
extractvalue (Value (wl), '*/description')
FROM test_xml
, TABLE (xmlsequence (extract (xml_data, '*/record'))) wl
but fails when description node contains a lot of data:
ORA-01706: user function result value was too large
I amended my query:
SELECT
extractvalue(Value (wl), '*/description').getClobVal()
FROM test_xml
, TABLE (xmlsequence (extract (xml_data, '*/record'))) wl
but this fails with:
ORA-22806: not an object or REF
Thanks in Advance

Hi Greg,
11.2.0.2.0 (Although I will need to do this on my work instance also which is 10.2.0.4)That's gonna be a problem...
Direct CLOB projection is supported starting with 11.2.0.2, using XMLTable or XMLCast/XQuery functions (extractvalue, extract, xmlsequence are deprecated now) :
SELECT x.*
FROM test_xml t
   , XMLTable(
       '/*/record'
       passing t.xml_data
       columns
         description clob path 'description'
     ) x
;On prior versions, implicit conversions will occur to VARCHAR2 datatype, hence the limitation observed.
AFAIK you have two options on 10.2.0.4 :
1) Using Object-Relational storage, with the xdb:SQLType="CLOB" annotation.
2) Using the following trick :
SELECT dbms_xmlgen.convert(x.description.getClobVal(), 1) as description
FROM test_xml t
   , XMLTable(
       '/*/record'
       passing t.xml_data
       columns
         description xmltype path 'description/text()'
     ) x
;

Batch Reading with Custom SQL

Hello,
Queries
1. Is it possible to use Batch Reading in conjunction with Custom Stored Procs/ SQL?
2. Is it possible to map an attribute to a SQL expression (like in Hibernate we have formula columns mapped using the formula* property)?
Background
1. We use Toplink 11g (11.1.1.0.1) (not EclipseLink) in our application and are controlling mapping using XML files (not annotations).
2. We are migrating a legacy application with most of its data retreival logic present in stored procedures to Java.
3. I am effectively a newbie to Toplink.
Scenario
1. We have a deep class heirarchy with ClassA+ at the following having a one-to-many relation with ClassB+ and ClassB+ having a one-to-many relation with ClassC+ and so on and so forth.
2. For each of these classes the data retreival logic is present in stored procedures (coming from the legacy application) containing not so simple queries.
3. Also there are a quite a few attributes that actually represent computed values (computed and returned from the stored procedure). Also the logic for computing the values are not simple either.
4. So to make things easy we configured toplink to use the stored procedures to retreive data for objects of ClassA+, ClassB+ and ClassC+.
5. But since the class heirarchy was deep, we ended up firing too many stored procedure calls to the database.
6. We thought we could use the Batch Reading feature to help with this, but I have come across documentation that says that it wont work if you override toplink's queries with stored procedures.
7. I wrote some sample code to determine this and for the heirarchy shown above it uses the speicifed Custom procedure (I also tried replacing the stored procs with custom SQL, but the behavior is the same) for ClassA+ and ClassB+, but for ClassC+ and below it resorts to its own generated SQL.
8. This is a problem because the generated SQL contains the names of the computed columns which is not present in the underlying source tables.
Thanks
Arvind

Batch reading is not supported with custom SQL or stored procedures.
Join fetching is though, so you may wish to investigate that (you need to ensure you return the correct data from the stored procedure).

Loading XML file in SQL Developer become ONE ROW !!

Hi:
I load the XML file to SQL Developer.
I found out that the XML files data are in one ROW?
Am I right?
Please let me know please
Sem

Hi RAGS1109,
If our XML data starts to get more complicated (multiple levels of elements / attributes), we start getting more outputs, we will have to join those outputs with a merge join transform.
Please refer to the following document how to dealing with multiple outputs for XML data source:

JMS and XML in PL/SQL

I'm prototyping a JMS Listener / XML Parser in PL/SQL. I've not used either technology in conjunction with PL/SQL before, so I'm looking for resources to aid my research.
Our current system is a Java Application that receives JMS messages off of a TIBCO EMS queue, parses the XML payload, and inserts the resulting records into the database using JDBC. What weâre hoping to do is to move all of this inside the database to improve the performance and reduce the network traffic. Recommendations of resources would be greatly appreciated!

My mistake...
exec dbms_aqadm.create_queue_table(queue_table=>'JMSDEMO_QUEUE_TABLE', queue_payload_type=>'sys.aq$_jms_text_message',multiple_consumers=>true);
instead of sys.aq$_jms_text_message, I used sys.xmltype
Once I corrected, things are working fine.

Problem loading XML-file using SQL*Loader

Hello,
I'm using 9.2 and tryin to load a XML-file using SQL*Loader.
Loader control-file:
LOAD DATA
INFILE *
INTO TABLE BATCH_TABLE TRUNCATE
FIELDS TERMINATED BY ','
FILENAME char(255),
XML_DATA LOBFILE (FILENAME) TERMINATED BY EOF
BEGINDATA
data.xml
The BATCH_TABLE is created as:
CREATE TABLE BATCH_TABLE (
FILENAME VARCHAR2 (50),
XML_DATA SYS.XMLTYPE ) ;
And the data.xml contains the following lines:
<?xml version="2.0" encoding="UTF-8"?>
<!DOCTYPE databatch SYSTEM "databatch.dtd">
<batch>
<record>
<data>
<type>10</type>
</data>
</record>
<record>
<data>
<type>20</type>
</data>
</record>
</batch>
However, the sqlldr gives me an error:
Record 1: Rejected - Error on table BATCH_TABLE, column XML_DATA.
ORA-21700: object does not exist or is marked for delete
ORA-06512: at "SYS.XMLTYPE", line 0
ORA-06512: at line 1
If I remove the first two lines
"<?xml version="2.0" encoding="UTF-8"?>"
and
"<!DOCTYPE databatch SYSTEM "databatch.dtd">"
from data.xml everything works, and the contentents of data.xml are loaded into the table.
Any idea what I'm missing here? Likely the problem is with special characters.
Thanks in advance,

I'm able to load your file just by removing the second line <!DOCTYPE databatch SYSTEM "databatch.dtd">. I dont have your dtd file, so skipped that line. Can you check if it's problem with ur DTD?

Portal 4.0 with MS SQL Server 2000 using CLOBs

Hello,
I'm driving Portal 4.0 with MS SQL Server 2000. I have encountered serious
problems when trying to persist events (e.g. RuleEvent) to database. In my
application-config.xml file I have JdbcHelper attributes
ShouldUseClobsForReads & -Writes set to 'false' as they should be or
mssqlserver4v70 driver.
It seems that when it is time to write the event to database, Portal4.0
can't find JdbcHelper MBean configuration values and therefore it uses
default values (=true) for both attributes.
Otherwise reading and writing works fine with MS SQL Server 2000 (at least
DATA_SYNC_ITEMs).
Any help appreciated.
Regards,
JR

Hi,
I would suggest better to have a backup of existing database remove your existing SQL server. Install the one given by SAP. And restore your previous databases.
