XML -- PL/SQL parser

I am trying to read a XML document using PL/SQL into the database ( to update or insert records). Could you point me in the right direction as far as documentation and may be samples. I have never used XML before and not really familiar with this technology.
Appreciate any help.
Thanks,
Mujahid.

Take a look at OTN's XML Home page. It includes links to Oracle's XML Developer's Kit (XDK) for PL/SQL.

These errors were due to not running initjvm etc. I have resolved all the jvm sqlj related problems now .

XML PL/SQL Parser Out of memory

Im parsing a 20M file and recieving the following result.
I have tried to cut the file size down and have found a small
version that will parse successfully.
We have tried adjusting
the ulimit -d 2097152
ulimit -s 32768
and also set java_pool_size = 41943040 in init.ora
none of these seemed to be enough to enable parsing of the file.
The following are 2 executions of the parser using 2 different
file sizes.
Thanks,

Performance degradation in pl/sql parsing

We are trying to use xml pl/sql parser and noticed performance degradation as we run multiple times. We zeroed into the following clause:
doc := xmlparser.getDocument(p);
The first time the procedure is run the elapsed time at sqlplus is something like .45sec, but as we run repeatedly in the same session the elapsed time keeps on increasing by .02 seconds. If we log out and start fresh, we start again from .45sec.
We noticed similar degradation with
p := xmlparser.newParser;
but we got around by making the 'p' variable as package variable, initializing it once and using the same for all invocations.
Any suggestions?
Thank you.

Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.
http://www.oracle-base.com/articles/10g/SQLTrace10046TrcsessAndTkprof10g.php
Also this informative thread can give you more ideas:
HOW TO: Post a SQL statement tuning request - template posting
as well as doing a search on 10046 at AskTom, http://asktom.oracle.com will give you more examples.
and reading Oracle's Performance Tuning Guide: http://www.oracle.com/pls/db102/to_toc?pathname=server.102%2Fb14211%2Ftoc.htm&remark=portal+%28Getting+Started%29

Hi Steven:
Yep...I just checked our install and there are no java classes in user_objects. We had the init*.ora file shared_pool_size set too low (as indicated under $ORACLE_HOME/javavm/doc/readme.txt).
So I'll get our DBA to try it again.
Thanks,
Derek

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

Importing/Parsing XML using SQL and/or PL/SQL

What is the recomended way of importing/parsing XML data using SQL and/or PL/SQL?
I have an XSD that defines the structure of the file, and an XML file that has the content in the appropriate structure. I have parsed (checked) the structure of the XML file using JDOM in my java application, and then passed it to a function in a package on the database as a CLOB.
What I need to do is parse the contents of the XML file that is passed into the function and extract the values of each XML element so that I can then do some appropriate validation before inserting and committing the data to the database (hence completing the import function).
A DBA colleague of mine has been experimenting with various ways of acheiving this, but has encountered a number of problems along the way, one of which being that he thinks that it is not possible to parse XML elements that are nested more than four levels deep - is this the case?
The structure of the XSD/XML that the database function needs to manipulate and import data from is very complex (and recursive by it's nature).
I would appreciate any suggestions as to how I can achieve the above in the most efficient manner.
Thanks in advance for your help
David

This is the forum for the SQLDeveloper tool. You will get better answers in the SQL and PL/SQL forum, and especially the XML DB forum.
Oracle has comprehensive and varied support for XML, including a PL/SQL parser.

Logging errors in PL/SQL Parser

Using PL/SQL Parser, is it possible to obtain the parsing errors
output in other place than a file (ref: setErrorLog function)?
as varchar variables or kind?

Does PL/SQL Parser Validate?

Just wondering if the PL/SQL parser can parse in validation mode?
I think I remember reading that the PL/SQL parser is a non-validating parser only but I didn't know if this changed.
Thanks for you help

I am also experiencing problems with the setDocumentType
This is my code
p := xmlparser.newParser;
xmlparser.parseBuffer(p,'<My_Data/>');
doc := xmlparser.getDocument(p);
docNode := xmldom.makeNode(doc);
xmldom.setVersion(doc, '1.0');
OuterNode := xmldom.getLastChild(docNode);
--Get DTD to parse against
xmlparser.setValidationMode(p,TRUE);
xmlparser.parseDTD(p,'c:\temp\v109.dtd','My_Data');
--Set DTD to validate against
docType := xmlparser.getDoctype(p);
xmlparser.setDoctype(p,docType);
xmlparser.freeParser(p);
The problem I am having is that the output now looks like this
<?xml version="1.0" encoding="UTF-8"?>
<My_Data>
</My_Data>
<!DOCTYPE My_Data SYSTEM "file:/c:/temp/v109.dtd">
The xmlparser.parseDTD requires as the third parameter the root element so the !DOCTYPE field comes after the root element and not before as required.
Hope this code helps a bit and if you solve the problem please let me know

PL/SQL parser for 7.3 DB?

SQL Parser supporting nested queries

I require a SQL parser that supprt nested queries. JavaCC doesnt support nested queries so that one is out. If anyone knows of any open sourse parser, please enlighten me. I have already looked enough on Google but not of much use.

| 1. as suggested , i was able to get the oraclexmlsql.jar

Could only be a CLASSPATH problem difference in your two
tests.
| 2. Is there anyway to supress the rownum attribute tag in

| setRowIdAttrName .... w/o using xslt
Not at this time. Rownum supression on the subquery should
probably follow your settings on the main query. I'll
suggest to the devs.
| 3. We are implementing a solution using these tools.... we

XDK Components for XML and XSLT are production.
XML SQL Utility and XSQL Servlet are still Technical

SQL Parsing Errors

We are running htmldb 1.5. We have an application running without problems on the development server. When we export the application and then import it on another server (QA or Production) we sometimes get the following errors in report regions that are retrieving data based on a page item:
failed to parse SQL query:
ORA-06502: PL/SQL: numeric or value error: NULL index table key value
The form with the page item is displaying the value for the item, but the reports based on the page item fail. If we go into the htmldb development environment and edit the page for viewing purposes, the problem appears to disappear from that point on. We do not make any changes to the page.
Is there a problem with the export/import process? Is there a way to make sure the page item has the value expected? We are using DML processing to fetch the record for the page. The fetch occurs 'After the Header'. Should the fetch be 'Before the Header'. Should we force a computation that reads the value into the page item again? If so, at what point?
Usually we invoke the page and set the page item values with a url that looks like:
f?p=&APP_ID.:510:#APP_SESSION#:UPDATE::510:P510_CLASS_ID:#CLASS_ID#
Thanks for your help,
Peter
