2-byte error in XML Parser for PL/SQL

environment:
oracle 8.1.5
XML parser for Java 2.0.2.6.0
XML parser for PL/SQL 1.0.1.0.0
we use CLOB as xml data container, but it does not work properly with 2 byte chracter set.
I tested same situation except using VARCHAR2 instead of CLOB, it works without problem.
I think there is some bug in method parseClob of oracle.xml.parser.plsql.XMLParserCover about converting CLOB into String.
I appreciate any help to work around this problem.

Hi,
We couldn't reproduce this error with our test case. Can you please post a test case that gives you this problem so we can assist you further?
Thank you,

I updated loadjava.bat to call JRE 1.1.8 instead of JRE 1.1.7.
Can't afford an upgrade to 8.1.6
Any help appreciated

It looks like you have not initialized JServer in your 8.1.5

Loading XML parser for PL/SQL

I am working my way thru 'Building Oracle XML Applications' by Steve Muench.
I am getting a problem when I try to install the XML parser for PL/SQL

About 20 classes get loaded correctly. All the rest get ORA-29545 or ORA-04043 errors.
I expect the ORA-04043 errors are a result of the earlier errors.
The documentation seems to indicate that there is no need to do
dbms_java.grant_permission to load into your own schema.
I have NT4 (sp6)
Oracle 8.1.7
xmlparserv2.jar dated 24/8/2001 17:01 size 1,177,259
xmlparserv2_2027.jar gives the same errors.
Any help would be appreciated.

Was it definitely xmlparsev2.jar that you had to load?
I recently started going through some of these examples as well and found that the standard xml parser was there but that I needed to load the xml parser for PL/SQL. I did this using loadjava from a subdirectory within the xdk directory and everything worked fine.

XML parsing problems with Oracle XML parser for PL/SQL

I am using the Oracle XML parser for PL/SQL to transform XML into HTML usign XSL. The parser gives me sporadic errors trying to parse various XML documents. For the same XML source, the XMLPARSER will parse without errors one day and the next day will give me errors such as "invalid char in text", "Expected ';'.", or even Java null pointer exceptions.
I have verified that the XML sources are well formed, so I am pretty certain that the problems I am having are bugs in the XMLPARSER.
Is there going to be a XML parser for PL/SQL version 2 that will fix these bugs? If so, when??? If not, is there anything else I could do to fix these problems?
Thanks!

You can use the latest version.

Oracle8.1.5 and XML parser for PL/SQL

Hi,
Does XML parser for PL/SQL work with Oracle 8.1.5? Did any one install the
same and if so what are steps to follow? I ran initjvm.sql to install
JServer and then tried to load jar files using loadjava, but it's giving
error. It's working fine with Oracle8.1.6.
Any idea?

Oracle XML Parser has differents distributions for 8.1.5 and 8.1.6 databases, try the correct version, then runs the oraclexmlsqlload.csh from the lib directory of XSU distribution.

Oracle 8i XML Parser for PL/SQL

Hi,
Using "Building Oracle XML Applications" by O'reilly, I am
trying to get XML working on an Oracle 8i database. I have done the following steps:
1) verify oracle.xml.parser.v2.DOMParser class is running;
select substr(dbms_java.longname(object_name),1,30) as class, status
from all_objects
where object_type = 'JAVA CLASS'
and object_name = dbms_java.shortname('oracle/xml/parser/v2/DOMParser');
CLASS STATUS
oracle/xml/parser/v2/DOMParser VALID
OK
2) Check for Oracle XML Parser for PL/SQL is installed:
DESCRIBE xmlparser
ERROR:
ORA-04043: object xmlparser does not exist
So apparently i need to download the Oracle XML Parser for PL/SQL.
I cannot locate this download on the oracle site for version 8i (8.1.7.4 specifically).
Any helpers out there?

You can use the latest version.

XML Parser for PL/SQL - charset

Hi,
I'm using XML Parser for PL/SQL and have some trouble with encoding of results xmldom.writeToBuffer and xmldom.writeToCLOB procedures.
Some tags in my DOM documents contain text values in RUSSIAN (server nls_charset is CL8ISO8859P5). When I write document in varchar2 variable, buffer content is in UTF8 encoding ( convert UTF8->CL8ISO8859P5 -OK).
xmldom.setCharset(doc, 'ISO-8859-5') just after xmldom.newDOMDocument has no effect.
xmldom.setCharset(doc, 'CL8ISO8859P5') has no effect also.
Explicit charset direction in third parameter of
xmldom.writeToBuffer and xmldom.writeToCLOB procedure has no effect.
When I write document in CLOB, and then read part of CLOB in varchar2 buffer - result contain '?' in place of all russian text characters.
What's a problem?
How can I force XML Parser write XML in server charset?
Platform:
Oracle8i Enterprise Edition Release 8.1.6.1.0
JServer Release 8.1.6.1.0
Oracle XML Parser for PL/SQL v 1.0.2

I have the same problem. But in my case I am allowed only to use XML Parser for PL/SQL.
Characterset 'WE8ISO8859P1' is used. And the language is latvian.
After parsing a XML document and printing its contents, all latvian characters are replaced by "f".
xmldom.setcharset(doc,'WE8ISO8859P1') has no effect.

Is this a bug or a typo of XML Parser for PL/SQL or something else?

Hello,
Below is a piece of codes I copied from the sample that comes with the XML parser for PL/SQL. I found that this sample could not be compiled since:
1- the method printElements takes in a parameter 'doc' of type 'xmldom.DOMDocument'
2- then this 'doc' is refered to in API method
xmldom.getElementsByTagName which takes two parameter, one of type DOMElement, the other of type char.
Are these tow types compatible?
where can i get a better documentation for the XML parser for PLSQ, the one come with the zip fileis not up to date since the miss documentation for DOM. thank you.

Using XML Parser for PL/SQL in 8.1.7

The XML Parser for PL/SQL is part of 8.1.7,
which is a good thing.
Now my question: What steps do I need to
perfom after installation of 8.1.7 to make
the parser available for my PL/SQL packages,
which call
xmldom.makeNode()
xmldom.appendChild()
xmlparser.newParser()
and other procedures from these packages ?
The schema SYS does not contain the
required packages XMLDOM, XMLPARSER, ...
after installation of 8.1.7.
Do I have to call loadjava and
sqlplus @load.sql extra as in 8.1.5 and
8.1.6 before ?
Of course I'd like to use the natively
compiled XML parser
libjox8_oraclexml_parser_v2.so.
Doesn't the above loadjava override the
installation of this fast parser ?
How can I be safe, that I am using the fast
parser under the PL/SQL cover ?
Tnx for your help
Richard
null

Richard,
That's weird? The packages were installed when I installed 8.1.7. You can just download the latest version of the XDK and reinstall using loadjava and then running the load.sql file to get the packages in. You should use the -f parameter for loadjava to force the new classes to be loaded over the old ones. For code examples and lots of other good tips on using the XDK, check out my new website for everything Oracle and XML at: www.webspedite.com/oracle.

XDK10g supports XML parsing for PL/SQL?

Hi,
I have a couple of questions here:
1) Does XDK10g support XML parsing for PL/SQL? (More specifically, I need to use xmlDom and xmlParser)
2) Does Oracle 10g come installed with XDK 10g? If not, does it even need to install XDK 10g to use xmlDom and xmlParser?
Thank you all and have a nice day.

Well, if you are talking 10.2, then
"The (Java-based) Oracle XDK PL/SQL packages XMLDOM, XMLPARSER, and XSL_PROCESSOR have been deprecated in favor of the (C-based) Oracle XML DB packages DBMS_XMLDOM, DBMS_XMLPARSER, and DBMX_XSLPROCESSOR. Synonyms have been provided to smooth the migration of legacy applications" (http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/whatsnew.htm#CHDCAICE)
Whether that is a default install option or one that requires selecting I can't say, but it is available without needing to additionally use the XDK. So odds are you can do whatever you need in PL/SQL using those DBMS_ packages (or XMLTYPE based variables if the need arises).

Installation of XML parser for PL/SQL, and XML_SQL

I have just migrated a 7.3.4.4 database to 8.1.7. Please could you tell me what I need to install (and where I would find the software and installation instructions) so that we can use the XML parser for PL/SQL and also XML_SQL. (NB Do I need to install java - and if so, again where would I find the installation software and instructions). Many Thanks.
Jenny

The XML Parser for Java comes preinstalled, as does the XML SQL utility.
Assuming your 8.1.7 Oracle home is represented by ?, you need to:
[list=1]
[*]cd ?/xdk/lib
[*]loadjava -v -r -u user/password xmlplsql.jar
[*]cd ?/xdk/plsql/parser/bin
[*]sqlplus user/password @load

XDK for PL/SQL and XML Parser for PL/SQL

Is there a difference between the terms:
XDK for PL/SQL
and
XML Parser for PL/SQL V2
or are they the same thing...?
cheers,

XDK stands for XML Developer's Kit. There are Oracle XDKs for Java, C, C++, and PL/SQL. These development kits contain building blocks for reading, manipulating, transforming, and viewing XML documents.
XML Parser is one component of XDK. Other components of XDK are
XSLT Processor, XSU, XSQL Servlet, XML Class Generator, etc.
For more information on XDK and its components please refer to:

XML-Parser for PL/SQL: OutOfMemoryError

When using the XML-Parser for transforming an
XML document into HTML, I sometimes get the
following error:
ORA-29516: Aurora assertion failure: Assertion failure at eox.c:187
Uncaught exception System error: java/lang/OutOfMemoryError
ORA-04030: out of process memory when trying to allocate 25509408 bytes (joxcx
callheap,ioc_allocate ufree)
The operation nevertheless seems to finish correctly. I run Oracle 8.1.6 under WinNT4
(384MB RAM) with a shared_pool_size of about
30MB and a java_pool_size of 40MB.
The original document is stored in a CLOB,
so I use xmlparser.parseClob to get it.
After the parsing is finished, the result is written to a file using xmldom.writeToFile.
Can anybody point me in the right direction?
Many thanks in advance!
