SAX Parser for Oracle 8.1.5

I need SAX parser - i want load this class into DB. Any ideas?
Adam

Have i possibilities to using some javatypes in oracle java stored procedure if this class is not loaded into db?
Cause i would like to create a java stored procedure to parse and insert some data from xml. I was thinking to pass xml file name as a parameter to my java procedure.
I must use Oracle 8.1.5 with jdk 1.1.7, and the best parser for me is SAX.
Please help.
Have i possobilities to use class inside oracle, which are placed outside oracle?
Something like classpath, where can i modify value (but classpath inside oracle)?

Java +XML (SAX) Parser for Oracle 8.1.5 EE

Hi there :)
I am looking java classes for SAX to parse XML. I cannot find a valid parser, cause after downloaded from Oracle XDK for java, when i try to load this calasses i get a messages that i alot of classes connot be resolved.
If somebody have valid classes on Ora 8.1.5 please send me mail.

ANy suggestions on improving performance of the parser.
ANy other approach I should be taking to load this file into DB.

SAX parser for PL/SQL

For a long time on technet the
PL/SQL parser release notes have
said that they will be supporting
SAX in a future release. Is there
any idea of when this support may
materialize? Or is Java the only
option for a parser in the db for
the near future that can handle large
documents?
null

What would you want to use as the implementation of the SAX2 ContentHandler interface in PL/SQL? Stored procedure-based callbacks? Just curious how you would envision this working. Your input is valuable to our future thinking in this area. Most teams using PL/SQL that want to use SAX have written Java Stored Procedures that use SAX internally inside the stored procedure (written in Java) but are not doing the SAX parsing with PL/SQL-based callbacks.

AGAIN - Needed SAX parser for java on Oracle 8.1.5

like in subject.
I load succesful sax2, but i need load more useful parser like from oracle or ibm.
But when i try i get a lot of errors like ORA-29534 (NullPointerOperation).
Kail

Only XML Parser v2 release 2.0.2.7 from Oracle works in 8.1.5, and this release does not support SAX2 unfortunately.

XML parser for Oracle 8i

I would like to use XMLparser for plsql in Oracle 8i. I know that I can download the parser from the OTN. Can anyone tell me how to install it to Oracle8i? or does Oracle 8i DBMS already has one installed/embedded into it as the default DBMS.
Furthermore, the directions in OTN tells us to install JKD1.1.x or above and GNUgzip?
Why do I have to install JDK to use the parser? and what is GNU gzip?
Thank you very much
Ben

There is a readme file in that package which
show you how to install it into your Oracle8i
database.

How to conevrt a Document into InoutSource for SAX parsing

I was trying to perform SAX parsing for a Document.
Can anybody help me out?
regards,
Ranjan

I need it because I have two big Documents with cross references depending upon business requirement. If I am doing DOM manilation then its very expensive in terms of performance. So I want to perform a SAX parsing.
One way to achieve this it to perform Transformation with
SAXResult result = new SAXResult(conHandler);//this is my DefaultHandler
transformer.transform(dsource,result); //dsource is the DOM source of my first Document
Is the any otherway around?
regards,
Ranjan

Xml sax parser

Hi all,
I am newbie to xml. I am using SAX parser for parsing xml documents. I have to write a code which parses all types of xsd files(including which can contain inline , referenced or both). Can anyone help / guide me how to code a generic xsd parser??
Thanks in advance,

An XSD file is an XML file, so you can parse it using sax.

SAX parser splits up character data; I expected Ign. whitesp

Im am working on a XML parser for loading data from some back
end systems into an Oracle 8i database. I am using the SAX
parser for this purpose. After doing some tests with larger
amounts of XML data (> 1M), I found some unexpected behaviour.
The parser sometimes splits up character data into two chunks of
data. The XML looks as follows:
<TAGNAME> this is the character data </TAGNAME>
The parser raises the following events:
1 startElement name = "TAGNAME"
2 characters chbuf = " "
3 characters chbuf = "this is the character data "
4 endElement name = "TAGNAME"
I expected an ignorableWhitespace event at step 2. The XML
document contains repetitive tagnames. The strange thing about
the parse process is that the parser splits up the character
data only sometimes, and I can't determine any kind of logica
for this behaviour. Most occurrences of exactly the same tagname
and character data are parsed correctly (that is, as I
expected).
Am I dealing with correct behaviour here, or is it a bug??

Thank you for your quick response.
In my test XML, there are about 27500 tags containing character
data. All character data starts with a whitespace character.
After parsing the xml, the whitespace of only 5 (!) tags is
treated as a seperate character event (so two character events
are raised in succession). The remaining tags all raise only ONE
character event for the entire character data. I can't explain
the difference in treatment.

SAX Parsing in Adapter Module

Hi All,
I need to build a custom Adapter Module where i want to use SAX Parsing for parsing XML document. I tried with a piece of Code but i'm getting following error while running the same:
Error occurred while sending message (GUID 6da4ff1c-3736-4990-1881-a8f09edd5fde): null
When i check the Audit Log the i just see following two lines:
Success Channel JDBC_s_Article_Grp1: Query executed successfully and confirmation skipped. Data may be sent again ("TEST" mode)
Send query result. Size: 1398556 characters
There are no logs being created for module at all. Also when i run the same code with DOM parsing, it works perfectly fine.
I have tries with re-deployment multiple times but no result.
Any pointers?
Regards,
Anurag

try to handle exceptions and use logging to know what the issue is.
That is the best way to troubleshoot your code

I've a problem with errors message in the sax parser

Hello,
I'm quite new to Java.
I'm trying to create a SAX parser for my XML file, with a XML schema.
When my pars run a XML file, the following mistakes go out:
1)org.sax.SAXParseException:s4s-elt-must-match: the content of 'restriction' must match (annotation?,.....)
2)org.sax.SAXParseException: src-ct.0.1:Complex Type Definition Rappresentation Error for type..... Element 'sequence' is invalid,misplaced or occurs to often
but I don't understand where I must go in the schema to correct.
Many thanks!

Hi,
Perhaps it would help if you post your XML file.

SAX Parser method charaters trouble

Hi,
I am using a sax parser for loading an xml file of size over 1gb. The problem whats happening is that the content gets truncated at random.
And this truncation happens in the characters method of the sax parser. This am sure as I logged the content I get from characters method before starting my processing. for ex:
<content>signal1,signal960</content>
<content>signal1,signal970</content>
On parsing the above snippet, the first content "signal1,signal960"
gets extracted completely, however the next one is truncated, and the truncation is random. This happens for some tags, and then the extraction resumes normally. And this truncation starts occuring again after it has extracted a few tags.
Also the first truncation started occuring only after parsing around 200 mb of the 1gb file.
Could anyone tell if there is some limitation with XERCES or CRIMSON.
or if any other one that I can use???
Regards,
R.

To quote from the Documentation of ContentHandler.characters:
-- start quote --
The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.
-- end quote --
So providing the content in two seperate calls is perfectly valid and must be handled by your code. It's probably a result of the internal workings of the XML parser and allowing that in the Parser specification probably allowed some optimizations that would otherwise be impossible (a constant buffer size, for example).

Using the SAX parser to split up a document to be processed by a DOMParser

I need to process a potentially large document which could prove too large to be read into memory at once by the DOM parser. The document would look something like..
(sorry about the formatting - can't use tabs!)
<Root>
<Parent>
<Child>
<Blah.....................
</Blah>
</Child>
</Parent>
<Parent>
<Child.......
</Child>
</Parent>
etc...
etc...
</Root>
The number of Parent elements could potentially be in the thousands. What I would like to do would be to use the SAX parser to read the document and when a Parent element is encountered, write the parent element and all its children to a stream in order that an input source can be created. The input source can then be parsed by a DOM parser. Once complete, the next Parent element encountered by the SAX parser could be passed to the DOM parser and so on until all of the Parent elements have been processed.
This way I can combine the ease of parsing the document using the DOM parser without having to worry about the overhead on memory.
Does anyone have any ideas as to the best approach? I could use the SAX parser for the whole thing but the XML is quite complex and lends itself to DOM parsing much more conveniently.

Can you read the file line by line:
start the reading at <child>
pause reading at </child>
copy the string to a var
wrap it with respective tags (<?xml<doctype etc...) and parse
proceed to the next <child>xx</child>
and repeat till you hit the closing of the file...
