Oracle XML Parsers DOM vs SAX
I have many huge XML formated data files I'm trying to importing into Oracle tables. The DOM model with XSL stylesheets will work great because many of the files XML element tags do not match the Oracle table column names. The problem is that the XML files are too large and memory is used up. Is there a compatible SAX solution to use a XSL stylesheet to map different columns to an Oracle table?
Thanks in advance

XSLT Transformation is based on the DOM representation of XML documents. However, you can divide the XML Document into small fragments before loading.
If you problem is just that the elements tags doesn't match the database columns, you can just using SAX to do the modification.
Thanks.

XML parser used in Oracle...DOM or SAX?
Hi,
My db version:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
Question:
I get an XML feed and load it into a temporary table T1.
My requirement is to load it in the exact sequence as I get the rows in xml and also populate a column in the temporary table as a sequence like 1 2 3 corresponding to the rows in the xml
When I do load the xml, it gets loaded in same order the xml feed is sent. So no worries.
But while I was researching I came to know that Oracle could use either DOM or SAX parser. If it uses SAX, then the order is maintained as in XML. But if DOM is used, the order wont be maintained.
Please let me know, how I can ensure that the xml order is maintained as it is while loading into temp table.I apologize, here is more details
{code}
CREATE TABLE XMLTEMPTBL
PARAM NVARCHAR2(30 BYTE),
PARAMORDERSEQ NUMBER(3)
XML format:
<?xml version="1.0"?>
<ROWSET>
<ROW>
<PARAM1>abc</PARAM1>
</ROW>
<ROW>
<PARAM2>def</PARAM2>
</ROW>
<ROW>
<PARAM3>ghi</PARAM3>
</ROW>
<ROW>
<PARAM4>jkl</PARAM4>
</ROW>
</ROWSET>
PROCEDURE insertparams (p_xmldoc IN CLOB)
IS
insctx DBMS_XMLSTORE.ctxtype;
ROWS NUMBER;
BEGIN
/*inserting insdoc into a temp table*/
insctx := DBMS_XMLSTORE.newcontext ('xmlTempTbl');
ROWS := DBMS_XMLSTORE.insertxml (insctx, p_xmldoc);
DBMS_XMLSTORE.closecontext (insctx);
END;
I want to insert into table this way:
select * from xmltemptb;
PARAM PARAMORDERSEQ
abc 1
def 2
ghi 3
jkl 4
{code}
My procedure is not 100% correct (but it gives an idea what code I am using to load into table), but I want to ensure the xml rows are loaded into the table in the same sequence. -
Experiences with Adobe XPAAJ, XML Parsers, OC4J /AS 10.1.2,10.1.3 and DB10g
Over the past couple of weeks we have been working on a solution which uses the newly available adobe XPAAJ api's (XML/PDF Access API for Java) for Java.
The client has a legacy requirement to where users are issued with a pdf form which they complete, save and upload to the server via a JSP. A neat bit of Java code utilizing the XPAAJ API's then strips out the form entered data and spits out XML. This is then parsed and inserted into relational tables within the schema.
Our solution needs to be deployed to an Oracle stack. However we ran into a number of problems when deploying the solution to AS 10.1.2. The adobe API's are not compatible with the Oracle XML Parsers. When extracting the form data, no error is reported and the code which performs the xml parsing just fails. Very nasty.
The main problem has been that Oracle XDK libraries have been hard-coded into the classpath of the container using the referential JAR file Class-Path mechanism. Altering this has required the use of the JRE extension library mechanism, or altering the boot classpath of the JVM when it is launched to load the alternative XML parser implementation instead. While this works, it has been an unsupported operation since the effect of this change is not limited to a specific application – it’s effect are felt across the entire container and this may lead to unpredictable results at runtime.
~http://www.oracle.com/technology/tech/java/oc4j/10131/how_to/how-to-swapxmlparser/doc/readme.html
We did look at a number of other solutions including embedding the java classes I'd written into the database. After loading the apache Xerces api's into our schema we hit upon the same problem. It seems that the same thing happens in the database and the Oracle XML parser is used by default.. Please see SR Number : 6153038.994 on Metalink.
If you can upgrade to AS 10.1.3 then you can follow the excellent how to at:http://www.oracle.com/technology/tech/java/oc4j/10131/how_to/how-to-swapxmlparser/doc/readme.html . Demo code can be found at: http://www.oracle.com/technology/tech/java/oc4j/10131/how_to/how-to-swapxmlparser/how-to-swapxmlparser.zip
The how-to details how to swap xml parsers within the application server.
Other possible solutions that are also available include:
- Shelling out to the OS from the DB or Apps Server, You can then execute the app as a command line app with a custom classpath. Very bad architecture design.
- Setting up an RMI client / server application where client is the db or apps server. You can find examples of this on the web. google 'Simple RMI example'.
- Bootstrapping the XML parser in AS 10.1.2 (unsupported).
I hope people have found this informative. It might save someone a lot of time.

so you talk about the db version. SOA 10.1.3.x runs on 10.2.0.1 and above (I ran for the longest time on XE) and if I remember correctly that's a warning, and not a hard prereq.
Regarding Appserver versions - soa 10.1.3 runs on AS 10.1.3 only -
Does anyone know which XML parser is used by default in the XPAAJ API's.
We are trying to compile an application into the Oracle Database. The solution then uses the internal Oracle JVM which strips out form data. However there appears to be a problem extracting xml data and we think its down to the Oracle XML parsers. Running the solution from the command line works as expected.
Anyone have any ideas?

KrisIn addition to what lk555 says, you have to specify the position of the node with reference to its other siblings to specifically point to the node you are referring to.
if you have the following structure:
<root>
<child/>
<child/>
<child/>
</root>
The third child is obtained by /child[3], instead of just /child. The value 3 specifies its position.
Hope this helps -
XML Validation using XDK SAX/DOM Parser
Hello,
I am trying to validate xml against xsd using SAX/DOM parser, both the files are stored as CLOB column in the database. I have the requirement to report all the validation errors and based on some helpful advice/code from the earlier posts in this forum, I have used the following code to validate and report the errors.
The code works fine but for large files it never goes beyond a certain number of errors i.e. getNumMessages() (XMLParseException) never returns value greater than 100 and thus limits the output of the validation errors. Any pointers to suggest change in code or an alternative will be extremely helpful.

Java.lang.ClassCastException: oracle.xml.parser.v2.XMLText cannot be cast to org.w3c.dom.Element
Hello
I am getting java.lang.ClassCastException: oracle.xml.parser.v2.XMLText cannot be cast to org.w3c.dom.Element error. This code is in java which is present in java embedding.
The SOA is parsing the xml in java code using oracle.xml.parser.v2 . This wont be a problem if the SOA uses default w3c DOM parser. How do i force SOA to use w3c DOM parser.
Is there any thing i can do with class loading?
Kindly help.

SharatCan you paste your java code here ? I assume, you must have tried type-casting.

How to remove element namespaces in XML file using DOM or SAX?
Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.

Edited by: Eddie Zhang on Feb 14, 2008 9:24 AMHi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks

Problem casting org.w3c.dom.Document to oracle.xml.parser.v2.XMLDocument
I have the following problem:
I get my xml-documents as an XMLType from the database and want to compare these using the supplied Oracle class oracle.xml.differ.XMLDiff (i use the java version supplied with Oracle 9i r2).
XMLType.getDOM() returns the xml-document as a org.w3c.dom.Document,
what i need for oracle.xml.differ.XMLDiff is a oracle.xml.parser.v2.XMLDocument.
How can i cast/convert between these two formats?
thanks!
p.s. cross-posting with Re: Casting/Converting XMLType to XMLDocument? (but i think this forum is more relevant).Hi,
thanks for the suggestion: i have written the code shown below. It results in a casting error.
As far as i know, i don't use a oracle.xdb.dom.XDBDocument, i only use a oracle.xdb.XMLType as the input parameter for my conversion-method:
any new suggestions ???
p.s. the second method which is commented does work, but is a bit verbose.

XML Parsing in Java Stored Proc--Oracle XML Support Installation?
I am working with a third party product that is having difficulty running a java stored proc that is parsing a supplied XML file. The proc basically looks like:
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
InputStream is = getXMLAsInputStream(xml);
try {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse( is );
... parse the document ....
catch (FactoryConfigurationError e) {
// unable to get a document builder factory
We are running on 9.2.0.6, HP-UX 64-bit. At first, when we would attempt to run the proc, a database hang would occur; now after attempting to install using loadjava jars for xerces2.6: ORA-29532: Java call terminated by uncaught Java exception:
javax.xml.parsers.FactoryConfigurationError: Provider
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found)
The vendor says that the errors we are getting when running are not due to any dependency on xerces or jre1.4, and that we need to "install Oracle XML support", but I'm not certain what this means (I cannot find any documentation on what to install). I believe that there are jars that need to be loaded into the database to support the XML parsing, as jre1.3 does not include built-in XML support, and Oracle 9.2.0.6 uses jre1.3.
So...does anyone have any thoughts as to how to resolve the missing references? Is there a way to "install Oracle XML support", or is it to install the necessary jars?
Thanks,

Need help, oracle xml db jar conflicts with sup app server v9
I am trying to create a web service on sun app v9 that will work with calls to oracle xml db on oracle 10gr2. I have successfully created a web service on other application servers (weblogic and websphere) but sun was the app server of choice. The oracle jar xmlparserv2.jar is causing problems with the sun server as it seems to have bundled some java classes from the javax.xml.parsers, javax\xml\transform (and even from dom, sax and streams sub folders) packages.
If I put the oracle jar in my war the error I get in the log file when accessing my webservice tester is:
[#|2007-08-13T08:37:48.691-0400|INFO|sun-appserver-pe9.0|javax.enterprise.system.stream.out|_ThreadID=15;_ThreadName=httpWorkerThread-8080-0;|error: http://www.w3.org/TR/html4/loose.dtd<Line 31, Column 3>: XML-20100: (Fatal Error) Expected '>'.

line ? of http://ann-griffithlap.jsc-eses.com:8080/TestWS/TestWSService?WSDL#types?schema1|#]
And the UI error from the tester call is:

I had attempted to move the xmlparserv2.jar elsewhere in the classpath for classloading and one error I got while trying different spots was:

which gets repeated for each deployment and then the server would not start up.
Is there any suggestions of where I can put the oracle jar to get sun to still start up as well as the jar to be available for use by the classes in my war that also contains the webservice that will call my underlying class? I have not found a way to eliminate the oracle jar if I want to do an xquery against oracle xml db.

ANN: Oracle XML Parser for Java v2.0.0.1
A new maintenance release of the Oracle Parser for Java is
available for download. It has the following fixes and changes:
Bug fixes for #920536, i.e. Cannot access element attributes via
XSLT; #898423. i.e. ElementDecl's in DTDs; #774774, i.e. DOM
extensions using XSL pattern matching; #863890 i.e. SAX
IOException not thrown.
New APIs in the following new interface:
1. oracle.xml.parser.v2.NSResolver
- resolveNamespacePrefix( find the namespace definition in scope
for a given namespace prefix )
New APIs in the following classes:
1. oracle.xml.parser.v2.XMLNode
- selectNodes( Selects nodes from the tree which match the given
pattern; client can provide an NSResolver implementation to
resolve namespace prefixes in the pattern ).
2. oracle.xml.parser.v2.ElementDecl
- getParseTree( Returns the root Node of Content Model parse
tree, which could then be traversed node by node using
getFirstChild() and getLastChild(). The Node types are: PLUS,
COMMA, ASTERISK, ELEMENT, QMARK ).
This is the first beta patch release for v2.

do i still need to do that step?No, you do not have to since "XML Parser for Java v9.0.4" is already installed as part of appsborg2.zip -
[CDATA] not the same way read in DOM and SAX (DOM: O.K., SAX: not O.K.)
I wrote a test application that reads a XML file. First method reads it via DOM in a Document object, second that reads it via SAX in a string. The output is almost the same but the character data is different:
while the dom outout is as expected:
<hap>EUSF</hap>
<name><![CDATA[WADDELL&REED ADV BOND CL Y]]></name>
the SAX output is different:
<hap>EUSF</hap>
<name>WADDELL&REED ADV BOND CL Y</name>
as both elements have text data, only the second is enclosed in a <![CDATA]> value. The DOM output is the same as when displayed the XML in internet explorer, so i guess this is the correct result. but my SAX reader does not display the <![CDATA]> value ...
to get the sax output i subclassed DefaultHandler and overwrote the methods like described in the Web Service Tutorial "Echoing an XML File with the SAX Parser" (http://java.sun.com/webservices/docs/ea2/tutorial/doc/JAXPSAX3.html#64190):
* Overwrites super.
* Receive notification of character data inside an element.
public void characters(char buf[], int offset, int len) {
String s = new String(buf, offset, len);
if (!s.trim().equals("")) { //suppress output of characters that are all whitespace
write(s);
}//characters()
the characters() method has the content of an element, but it has not the information if a CDATA is enclosing the data or not(?). How can this be done?There's a thing called a LexicalHandler (org.xml.sax.ext.LexicalHandler) that has startCDATA and endCDATA methods. The API documentation suggests that you could create your own LexicalHandler and use it somehow, but it doesn't give you a nicely packaged example. I don't have an example of it either, sorry.
However despite what you say, those two outputs are not different. In XML terms they are identical and parsers will treat them identically. -
Java.lang.NullPointerException javax.xml.parsers.DocumentBuilder.parse
Hi all,
i have a problem by solving an error in my code. The Code is mainly from Ian Darwin.
The code i am running works with j2sdk1.4.2_04. But now i have to bring it to work with jdk1.6.0_13.
The code parses xml documents. With small xml documents the code works. With large xml documents i get the following error while running the produced class file.
Exception in thread "main" java.lang.NullPointerException

I know what a java.lang.NullPointerException mens. But i don't know where i have to look for. Specially i don't know what or where "com.sun.org.apache...." is.
Is there a package that a have to add to the environment? Can some one tell my where i can find this package?
I wrote the code for some years ago, 2006 or so. With the knew jdk1.6.0_13 some thinks chance in the environment. Couldn't find what exactly.
The code has only 215 lines, but some how i can't add it to this Message, because Maximum allowed is only 7500.
Is there an other Forum, which may is better for my question?Here is the code:

NoSuchMethod: javax.xml.parsers.SAXParserFactory.getSchema()
Hi All,
In a servlet I have created a SOAPMessage object based on the request received, and when I execute
message.getSOAPBody I get the message:
java.lang.NoSuchMethodError: javax.xml.parsers.SAXParserFactory.getSchema()
I am running tomcat with jdk 1.5 and I am using saaj-api.jar, saaj_imp.jar and Fastinfoset.jar from jwsdp 1.6
Anyone got any ideas what to do ?
Kind regards,
Marco LaponderAlong with jdk1.4.2, Sun has bundled a currently ancient version of JAXP.
So, get a recent version of a JAXP implementation (e.g. with JWSDP1.6), probably contained in jar-files called jaxp-api.jar, dom.jar, sax.jar, xalan.jar and xercesImpl.jar, and add these to your classpath when you're compiling/running.
You're not done yet! Because the old jaxp libraries are bundled with your JVM, the classloader will find them through your bootclasspath, and they will be prefered above the new implementation you just added to the classpath. To resolve this, the JVM creators came up with the endorsed mechanism. This allows you to provide new classes for a list of predefined packages. These classes are already included in the jvm distribution, but are foreseen to be updated. See for more information about the endorsed mechanism: http://java.sun.com/j2se/1.4.2/docs/guide/standards/ .
So to be short, you also have to make the jvm recognise them as endorsed libraries. E.g. by adding them to the <java-home>/lib/endorsed directory or by setting the java.endorsed.dirs property to the directories which include the new jar files.
Your commandline to run app.class would become: java -Djava.endorsed.dirs=/home/endorsedDir;/anotherDir app
