SAX Parser,setValidationMode

We have to parse an XML of 5 MB size and load into the
Database.We started using the DOM Parser(PL/SQL) and getting the
Out of Memory errors.(The Java Pool Size is 250 MB).As per the
Oracle Documentation we have stated using the SAX Parser.But
Using SAXParser we are not able to use the "setValidationMode"
Method.I am getting "Method setValidationMode(boolean) not found
in interface org.xml.sax.Parser." error message.
Can any one help me what is the problem.
Thanks in Advance.

SAX should mask the fact that some content is specified inside of a CDATA section.. It is just characters.
The safest way to process characters is to setup a StringBuffer or equivalent in the startElement method. There is a variation of the StringBuffer append method that has the same three parameters (char[], int, int) as the characters signature. The characters method may be called many times before you are given all of the content of the string. How it decides when to call you depends on the parser and is subject to change over time. But, if you accumulate the contents in each call of characters and do the toString() in the endElement method you are going to get the right content. Lots of people over the last year or so that I've been involved in this forum have had other ways they thought were better than this, but most of them have eventually tried and accepted this way because it works and their "better" way did not.
It looks like you got the content for the CDATA section (Please refer...).I'm not sure what your problem is.

Is there a SAX parser with PL/SQL??

Hi All,
I am a Oracle developer and generally want to do everything from PL/SQL.
So, from a PL/SQL procedure I would like to parse a XML document. I have tried hard to find a PL/SQL package which can give me a PL/SQL SAX parser, but could not find one.
All packages are based on DOM tree.
Please convey if I am wrong and is there a SAX parser?
I know that there is only one package DBMS_XMLSTORE which is C based and uses SAX parser, but it does not have procedures/functions like ".parse()".
Thanks and regards

Here's an example

How to deal with empty tags in a SAX Parser

Hi,
I hope someone can help me with the problem I am having!
Basically, I have written an xml-editor application. When an XML file is selected, I parse the file with a SAX parser and save the start and end locations of all the tags and character data. This enables me to display the xml file with the tags all nicely formatted with pretty colours. Truly it is a Joy To Behold. However, I have a problem with tags in this form:
<package name="boo"/>
because the SAX parser treats them like this:
<package name = boo>
</package>
for various complex reasons the latter is unaccetable so my question is: Is there some fiendishly clever method to detect tags of this type as they occur, so that I can treat them accordingly?
Thanks,
Chris

I have spent some time on googling for code doing this, but found nothing better, than I had to write in by myself.
So, it would be something like this. Enjoy :)

XML - SAX Parsing Question

Hi,
I am parsing XML using SAX parser and fill the values into the HashTable ( like Key value pair ).. so i can get the vaues for a particular key using hash get function.
For the following XML. There are 2 "subscriberNumber" attribute, one is under "sn:Subscriber" and the another is under "sn:SubscriberChange".
I can able to put this values in hash table and when i print the Hash table it is printing as sn:subscriberNumber=[1234567890, 1234567890] .. But how will i know which one is from "sn:Subscriber" and which is from "sn:SubscriberChange"
This is the XML :
<sn:SubscriberNotification>
<sn:notificationSubType>1120</sn:notificationSubType>
<sn:Subscriber>
 <cng:PaymentType>PostPaid</cng:PaymentType>
 <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:Subscriber>
<sn:SubscriberChange>
 <sn:subscriberNumber>1234567890</sn:subscriberNumber>
</sn:SubscriberChange>
</sn:SubscriberNotification>
Any suggestion and pointers are really helpful
Thanks,
-Raj..

Try something like this:
import java.util.Stack;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
class MyHandler extends DefaultHandler {
 Stack openTags = new Stack();
 public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
 if (qName.equals("sn:subscriberNumber")) {
 String parentTag = (String)openTags.peek();
 System.out.println("Parent tag of this <sn:subscriberNumber> is : <" + parentTag + ">");
 openTags.push(qName);
 public void endElement(String uri, String localName, String qName) throws SAXException {
 openTags.pop();
}Regards

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.
See :
http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/sax/2a_echo.html
http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/sax/work/Echo02.java

XML SAX parser that support LexicalHandler

Hello,
I'm looking for an XML SAX parser that support a LexicalHandler.
I have xml files that are not well formed, ie: (&, <, >, etc...) characters within tags and I need to ignore them.
Anyone have a link to some opensource library ??
Thanks,
Samir

Don't waste your time. Using a LexicalHandler isn't going to help with parsing malformed XML. You should get the person who produced those files to replace them with correct XML.

Why are all the events in the XML SAX parser not activated?

Hi everyone,
I have written a mini server that parses XML files into SQL queries.
Below is a segment of my code;
 try {
 Class.forName( JDBC_DRIVER );
 myConnection = DriverManager.getConnection( DATABASE_URL, "username", "password");
 EventXMLParser myEXP = new EventXMLParser(directory, myConnection);

 myEXP.XMLtoDB(xmlFile);
 outWriter.println("File:" + xmlFile.getName() + " DONE");
 } catch (SQLException e) {
 System.err.println("SQLException for establishing connection");
 e.printStackTrace();
 } catch (ClassNotFoundException e) {
 System.err.println("CLASS NOT FOUND EXCEPTION HERE");
 e.printStackTrace();
 } catch (Exception e) {
 System.err.println(e);
 e.printStackTrace();
 finally {
 outWriter.println("PARSING COMPLETED");
 outWriter.close();
 }Where the constructor EventXMLParser constructs the following:

 try {
 this.XMLpath = path;
 this.db_connection = connection;
 this.xr = XMLReaderFactory.createXMLReader();

} My question is: I have taken my SQL query generated by toSQL() method in events and it worked.
Here is the funny thing:
Everything is correct syntax wise: No complaints what soever
The mysql part works: Tested separately.
So I tend to think that the problem lies within the SAX parser. I have written SAX2 parsers on this machine before and they have worked too. I tried inserting println statements all over startElement endElement etc etc only to find out that the SAX parser did not call any of the methods that I overided!! Why is that so?
Can you guys spot where my SAX parser fails?

I see.
I try to correct this problem by removing super();
so right now my code looks like this:
 static Event temp = new Event(0, 0, "null", "null", new Date(), 0, "null", 0);
 static String CurrentElement = null;
 static File XMLpath;
 static Connection db_connection;
 static XMLReader xr;
 static DefaultHandler XMLSAXhandler;
 //Constructor, Build the SAX Parser
 public EventXMLParser(File path, Connection connection) {
 try {
 this.XMLpath = path;
 this.db_connection = connection;
 this.xr = XMLReaderFactory.createXMLReader();
 this.XMLSAXhandler = new DefaultHandler(); //create a new own handler
 this.xr.setContentHandler(XMLSAXhandler);
 this.xr.setErrorHandler(XMLSAXhandler);
 //System.out.println("DEBUG: db_connection is " + db_connection.toString());
 catch (Exception e) {
 System.out.println("Constructor Error!");
 e.printStackTrace();
 }This time, I created a new instance of default handler() which can be referenced by as the objects's XMLSAXhandler. However, that did not solve the problem, why does the problem still persist?
Right now, there is only one instance of a default handler created. So why does all my parsing event functions still get ignored?

How to Create XML file with SAX parser instead of DOM parser

HI ALL,
I am in need of creating an XML file by SAX parser ONLY. As far as my knowledge goes, we can use DOM for such purpose(by using createElement, creatAttribute ...). Can anyone tell me, is there any way to create an XML file using SAX Parser only. I mean, I just want to know whether SAX provides any sort of api for Creatign an element, attribute etc. I know that SAX is for event based parsing. But my requirement is to create an XML file from using only SAX parser.
Any help would be appreciated
Thanx in advance
Kaushik

Hi,
You must write a XMLWriter class yourself, and that Class extends DefaultHandle ....., the overwrite the startElement(url, localName, qName, attributeList), startDocument(), endElement().....and so on.
in startElement write your own logic about how to create a new element and how to create a Attribute list
in startDocument write your own logic about how to build a document and encodeType, dtd....
By using:
XMLWriter out = new XMLWriter()
out.startDocument();
Attribute attr1 = new Atribute();
attr1.add("name", "value");
out.startElement("","","Element1", attr1);
Attribute attr2 = new Atribute();
attr2.add("name", "value");
out.startElement("","","Element2", attr2);
out.endElement("","","Element2");
out.endElement("","","Element1");
out.endDocument();

Sax parser problem

hi,
i am assuming the problem is with sax parser but i cant be sure. I am parsing a xml file (about 1.4MB) with some data in it. the parser i have created reads the xml file correctly for the most part but when at some point the
"public void characters(char buf[], int offset, int len) throws SAXException"
function stops working correctly....i.e it doesnt fully read read the data between the "<start>" and "</start>" element. say it reads about 100 id's correctly---for 101 ID it does this. This is just an example. Since, the problem might be with how :
"public void characters(char buf[], int offset, int len) throws SAXException"
function is reading the data i was wondering if anybody else had encountered this problem or please let me know if i need to change something in the code: here's a part of the code :

I haven't gone through your code but I also had a similar error....and the exception in my was because of an "&" instead of the entity reference & in one of the element values. I use a non-validating parser but if you use a validating one then this might not be the reason for your exception.

SAX Parser

I am using the sax parser provided by the package javax.xml.parsers to parse an XML file. It works fine as long as I have an XML file which has English characters. When I use it for parsing a file which has Korean characters in it, the parser fails to recognize them.
It used to throw an error "Line too long" on reading the Korean characters. Then I added an XML directive encoding="EUC-KR" and now it reads the file but does not recognize the characters correctly. It reads all the korean characters as question marks ('??').
Any pointers on what can be done to fix this problem.
Thanks,
RahulJ

Hi,
We've got a very similar problem. I'm parsing with SAX and DOM but the MS special characters keep appearing as ? or ??.
If the encoding is not specified in the XML file there are Parser Exceptions. If I set the encoding to "JISAutoDetect", "JIS", "MS932", "Cp1250 to Cp1258" or "ISO8859-1" then there are no exceptions but the stray characters still appear as ?s.
I managed to display the left and the right quotation marks in a servlet by setting the response Content Type to "text/html; charset=Shift_JIS" and the encoding="Cp1252" in the XML file. But I still have problems with the rest of the characters.
What kind of output do you use? Do you display in a web page or you just write to a file?
Thanks,
Ross

Using the SAX Parser

As I reported in this thread: Carriage Returns in XSLT output I am trying to produce a text output file with each line terminating in cr-lf (using the output from ViewObject.writeXML() passed through the XSLProcessor.processXSL() method to apply a XSLT stylesheet transformation to it), but the cr characters in the stylesheet are being converted to nl characters, so I am ending up with two nl characters at the end of each line.
I found a 2002 query (here: http://www.xslt.com/html/xsl-list/2002-04/msg00193.html) by someone with the same problem, and a reply by Steve Muench explaining it and stating that the Oracle SAX parser does not have the same problem.
So my question now is - does the SAX parser still retain cr characters (or is it too now converting them to nl) and if it does, how do I make XSLProcessor.processXSL() use it rather than the default XML parser? Can I do it from within my code, or does it need to be set in some sort of environment variable? We are on version 9.0.5.2 of JDeveloper(10g)

JDBC receiver adapter - Error processing request in sax parser

Hello,
I want to INSERT idoc data via JDBC adapter into a MS SQL database. After digging through SAP Help, numerous blogs and forum discussions on SDN and even posting an OSS message I still get the same error:
'Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)'
When testing my mapping in the Integration Repository the resulting XML message is:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Employee xmlns:ns0="http://prodrive.nl/xi/HRMasterdata/HRMD_A_2_d_bcommerp">
 <STATEMENT>
 <T_PD_Employees action="INSERT">
 <access>
 <KeyTag>00088888</KeyTag>
 <PerNo>00088888</PerNo>
 </access>
 </T_PD_Employees>
 </STATEMENT>
</ns0:Employee>
The connection to the database is fine, Sender adapter with a SELECT * works perfect.
Can anyone help me solve this problem? I'm lost.
Best regards,
Roelof Jan Bouwknegt

Hi Bhavesh,
I have tried out the change you suggested. Without success. Message I get back is
- 2006-12-28 10:34:08 CET: Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)

 <PERNO>00088888</PERNO>
 </ACCESS>
 </T_PD_Employees>
 </STATEMENT>
</ns0:Employee>
Somehow the SAX parser doesn't like the result of my mapping. Maybe there is something wrong with the structure cardinality. Let me describe what I have built:
XSD:
WA_T_PD_Employees - Complex Type
> STATEMENT - Element - Occurence = 1
>> T_PD_Employees - Element - Occurence = 1
>>> STATEMENT - Attribute - Occurence = optional
>>> access - Element - Occurence = 1..Unbounded
Best regards Roelof Jan and thanks for your quick response

Error processing request in sax parser

Hi all,
I am doing an asynchronous interface.
It is an interface from IDOC to JDBC. While testing the interface,am getting the following error
"Error processing request in sax parser: Error when executing statement for table/stored proc. 'put_delivery' (structure 'Statement_Delivery'): java.lang.NumberFormatException: null"
Any kind of help is appreciated.
Regards,
Thireesha.

Hello,
Please refer to SAP NOTE 801367.
In advanced tab, use logSQLQuery-->true. Tt will display the actual sql statement in audit log instead of xml format.
You can copy this sql statement and execute directly in database to check the problem.
