Embedding XML in XML for writing to database

I am creating a BPEL process in Oracle BPEL Manager 10.1.2.0.2 which will read an XML file using a file adapter, perform some XPath operations on the document to obtain attribute values from its content, then write those values and the document itself to a database table using a database adapter. The attribute to receive the document is a CLOB of type SQL.XMLType.
Given that use of a database adapter typically involves using a stylesheet to map the contents of a working document to a document reflecting the table schema, how do I go about mapping the XML document (as an unparsed string, with all tags intact) to the element of type string that represents the value to write to the XMLType CLOB? Every technique I've tried thus far strips away the tags.
Thanks for your time,
Paul Camann

Hi Rauno,
that sample was added in 10.1.3.1 but the idea should work in 10.1.2.0.2.
I am copying and pasting the key parts of that README.txt:
<copy>
<from expression="ora:getContentAsString(bpws:getVariableData('Invoke_1_readMovieSelect_title_param_OutputVariable','MoviesCollection'))"/>
<to variable="Invoke_2_merge_InputVariable"
part="MoviesAsClobsCollection"
query="/ns6:MoviesAsClobsCollection/ns6:MoviesAsClobs/ns6:xml"/>
</copy>
Notice the use of the ora:getContentAsString custom function.
The assign looks like this (in .bpel)
<assign name="Assign_4">
<copy>
<from expression="ora:parseEscapedXML(bpws:getVariableData('Invoke_3_readMovieAsClobSelect_title_param_OutputVariable','MoviesAsClobsCollection','/ns5:MoviesAsClobsCollection/ns5:MoviesAsClobs/ns5:xml'))"/>
<to variable="outputVariable" part="payload"
query="/ns4:MoviesCollection"/>
</copy>
</assign>
Those are the two xpaths you need for converting an xml to a CLOB/string and vice versa.
Thanks
Steve

Selective XML Index feature is not supported for the current database version , SQL Server Extended Events , Optimizing Reading from XML column datatype

Team , Thanks for looking into this ..
As a last resort on optimizing my stored procedure ( Below ) i wanted to create a Selective XML index ( Normal XML indexes doesn't seem to be improving performance as needed ) but i keep getting this error within my stored proc . Selective XML
Index feature is not supported for the current database version.. How ever
EXECUTE sys.sp_db_selective_xml_index; return 1 , stating Selective XML Indexes are enabled on my current database .
Is there ANY alternative way i can optimize below stored proc ?
Thanks in advance for your response(s) !

Confusion for writing Crawling Data to Which XML Methods?

Hi,
I am stucked over here as i m going to use XML.
Problem Having :-
I have implemented the Crawling code .
In which I have written the upcoming Main urls and and its sublinks in the Different Text File with the Incremented numbers.
But in the Text files i can't see each and every URl's Grand Parent ,Parent and Child Relations.
So, it generates the confusion and more time to see which URl having which Sublinks and its Text Files.
Thinkable Approxiamte Solution from my side
To use XML for Writing the Crawling processed all links Grant Parent, Parent and Child Relation Ships.
Which can be useful for Traversing all the links Parent and Child relation Ship into only 1 XML file.
XML files after that will used to read line by line and fetch the uRLs and that will used for other process ahead.
Question Having:
There are so many XML Methods available on the internet.(i.e. XMLwriting,XML Beans,Dom4j,XML Parser,SAX Parser,Dom Parser)
So which method should i used for reading and writing the Crawling Parent and Child Relation ship using Good Schema.?
Pls provide some code or useful links or any Suggetion which makes me to reach at solution.

Use the Write Waveforms to File VI to write to a tab delimited text file. Excel can open those up just fine.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Choosing between SAX & DOM & StringBuffer class for writing XML

Hii Javaties
I need to create a XML document from a swing application.
I need to store this xml in a file.
For writing XML which parser should i use SAX or DOM or should i go for StringBuffer class.

I'm not aware of a way to use SAX to create an XML document. It is used to view the contents of an existing XML document or data that is well-structured.
That leaves you with a choice of DOM or StringBuffer. We cannot tell enought about what you are doing to know which is better. Each has some advantages and disadvantages.
StringBuffer:
+ less overhead
- no assistance in ensuring the validity of the result
+ greater control over layout of resulting document (how and when to indent)
- any control over layout must be done by you.
DOM (although this task is easier in JDOM)
- more overhead
- some learning curve
+ result is guaranteed to be valid XML.
+ there are pretty formatters to generate good looking results
- there may be layout choices that the standard pretty formatters cannot do
As an example, consider this part of the Document being created.
You want <name>John Doe</name>
With a StringBuffer, you can just add these pieces. With DOM, you need to:
1) create an Element named "name".
2) create a Text object with a value of "John Doe".
3) add the Text object as a child of the Element
4) add the Element to the parent
Having done the DOM version (also a JDOM version) several times, I have developed an XMLHelper class that has several static methods to make simple, common constructs.
It lets me do things like:
parent.addChild( XmlHelper.makeElement( "name", customerName ) );
So, the answer to your question is the same as many other questions: It depends.

Wrong XML OraDbType code for database column type CHAR

Hi there!
I have a strange issue with the XML retrieved from an Oracle DB. I'm using OraDB11g and my problem is described next:
When I create a table with a CHAR type columns and get the XML from a query the returns a cursor with the table rows, I get the supposed right OraDbType code 104:
Table creation:
create table AA_Table1
ID number(2,0) not null,
ColumnA char(1) null,
ColumnB char(1) default 'S' not null,
constraint PK_AA_Table1
primary key ( ID )
tablespace "X"
storage
compress for all operations
and the returned XML:
<?xml version="1.0" encoding="utf-16"?>
<xs:schema id="o_ListaTable" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop">
<xs:element name="o_ListTable" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="o_List" msprop:REFCursorName="REFCursor">
<xs:complexType>
<xs:sequence>
<xs:element name="ID" msprop:OraDbType="111" type="xs:short" minOccurs="0" />
*<xs:element name="COLUMNA" msprop:OraDbType="104" type="xs:string" minOccurs="0" />*
*<xs:element name="COLUMNB" msprop:OraDbType="104" type="xs:string" minOccurs="0" />*
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
BUT...when I insert another column on the table, changing it, after that, I get a wrong OraDBType code on the returned XML for the new added column...
Added new column:
alter table AA_Table1 add ColumnC char(1) default 'S' not null;
The returned XML is:
<?xml version="1.0" encoding="utf-16"?>
<xs:schema id="o_ListaTable" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop">
<xs:element name="o_ListTable" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="o_List" msprop:REFCursorName="REFCursor">
<xs:complexType>
<xs:sequence>
<xs:element name="ID" msprop:OraDbType="111" type="xs:short" minOccurs="0" />
<xs:element name="COLUMNA" msprop:OraDbType="104" type="xs:string" minOccurs="0" />
<xs:element name="COLUMNB" msprop:OraDbType="104" type="xs:string" minOccurs="0" />
*<xs:element name="COLUMNC" msprop:OraDbType="126" type="xs:string" minOccurs="0" />*
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
My question is: why is this OraDbType code different? Check that the same column type CHAR(1) NOT NULL DEFAULT 'S' is created on table create and the OraDbType is ok, so I think this can be a bug...Because of this, I cannot do a right XML parser to convert CHAR(1) columns in other type I want, in this case, to convert it to .Net bool type. My parser now is ignoring the OraDbType code 126, because this is also the code used for nvarchar2, and I won't convert nvarchar2 to bool.
How can I solve this problem?
Some additional tests I've done:
Have also inserted new columns nullable/not nullable and with default value:
alter table AA_Table1 add ColumnD char(1);
alter table AA_Table1 add ColumnE char(1) not null;
alter table AA_Table1 add ColumnF char(1) default 'S';
And the returned XML was:
<?xml version="1.0" encoding="utf-16"?>
<xs:schema id="o_ListTable" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop">
<xs:element name="o_ListTable" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="o_Lista" msprop:REFCursorName="REFCursor">
<xs:complexType>
<xs:sequence>
<xs:element name="COLUMNA" msprop:OraDbType="104" type="xs:string" minOccurs="0" />
<xs:element name="COLUMNB" msprop:OraDbType="104" type="xs:string" minOccurs="0" />
<xs:element name="COLUMNC" msprop:OraDbType="126" type="xs:string" minOccurs="0" />
*<xs:element name="COLUMND" msprop:OraDbType="104" type="xs:string" minOccurs="0" />*
*<xs:element name="COLUMNE" msprop:OraDbType="104" type="xs:string" minOccurs="0" />*
*<xs:element name="COLUMNF" msprop:OraDbType="104" type="xs:string" minOccurs="0" />*
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
All OraDbTypes are right, except that one for the column not null and with default value. Any solution for this issue?
If I change the type of the column that returns the wrong code (ColumnC) to CHAR(1) null default 'S' and then change it again to the original type CHAR(1) not null default 'S', I get the right ORaDbType code 104 as expcted and not the 126. This behaviour is strange - can this be an Oracle bug?
I am using the following Oracle DLL and respective version:
oci.dll (version 11.2.0.1)
Oracle.DataAccess.dll (version 4.112.3.0)
orannzsbb11.dll (version 11.0.0.1)
oraocci11.dll (version 11.2.0.3)
OraOps11w.dll (version 2.112.3.0)

Have you tried using minOccurs="1" ? Since the column is not null, it is guaranteed 1 value, correct?

Embedding data from xml file into metadata of a pdf

Hi All
I'm wanting to do the following, but struggling to figure the right way to go about it.
I want to embedded data from my MIS into a pdf's metadata (as scrnshot). I can create a standalone xml file with all the data I require, but I'm unsure how to automate that being embedded into a pdf's advanced metadata. I know this can be done, as it worked at a previous employer, but I didn't get chance to find out how they did it.
I'm wanting to do this so I can carry out a more advanced search of the metadata in Bridge.
Any advice would be appreciated!

Hi Northern,
    I have modified the modifyingXMP sample for you. After this change, put your xmp file as sample.xml and also put pdf file in the same folder where ModifyXMP executable is. After merging my changes, ModifyXMP file will read the sample.xml and will embed it into pdf file.
   Please follow the following steps
1. Download XMPToolkit SDK and follow the steps to compile Sample
2. Open ModifyingXMP file, replace all the content of that file with the below content
3. Compile the ModifyingXMP file.
4. The ModifyXMP.exe will be generated in folder (samples\target\windows\Debug), if you have changed the output folder it will be generated there.
5. In parallel to ModifyingXMP.exe put the sample.xml (the xml file you have) and also the pdf file (say pdf file name is mypdf.pdf)
6. Go to console and change directory to the directory where ModifyingXMP is and pass the following command
ModifyingXMP mypdf.pdf
7. Open the pdf file and check that value/properties
For your reference, I am putting the content of the sample.xml file too, put this content in sample.xmp and any pdf and you will find subject field is getting added.
************** content of the sample.xml file. Create a file name sample.xml and put that content. Put sample.xml in parallel to ModifyingXMP.exe*******

Extract Embedded XML within XML using XSLT

Hi,
We have a unique scenario where our incoming payload is coming from Oracle Database table which has one column of CLOB type storing complete raw XML.
We need to extract this embedded raw XML and process it further, each XML has a unique XSD associated and we have that details in a separate column.
So our DBAdapter incoming payload looks like below
<rows>
<row>
<xml_xsd>xyz.xsd</xml_xsd>
<xml>RAW XML DATA</xml>
</row>
<row>
<xml_xsd>xyzv2.xsd</xml_xsd>
<xml>RAW XML DATA</xml>
</row>
<row>
<xml_xsd>xyzv2.xsd</xml_xsd>
<xml>RAW XML DATA</xml>
</row>
<row>
<xml_xsd>xyzv3.xsd</xml_xsd>
<xml>RAW XML DATA</xml>
</row>
</rows>
How can we leverage XSL Transformation to extract this embedded XML in each row? I need the each individual XML available for further mapping. I can split the payload using XPATH filtering per XSD, but not able to find a solution to parse the embedded XML and assign to a target schema?
Research done so far points to do two transformations to get resulting XML or using Saxon Parser if available and use the parse() extension.
Any other ideas/suggestions will be helpful. Challenge here is performance as i need to do this in bulk, will have many rows to process
Thanks in advance.

Hi,
You dont have finite set of XSD's and probably you wont be creating a variable for each type of xsd from that finite set.
Secondly, xslt doesnt support dynamic xpath as per my knowledge.
Question:
Do you really need XSD to do the validation?
A possible solution to your question would be using java approach as below: Pass the xml and the xpath query
    public String evalXpath(String xml, String xpathQuery) {
          String xpathResult ;
        DocumentBuilderFactory domFactory =
            DocumentBuilderFactory.newInstance();
        try {
            DocumentBuilder builder = domFactory.newDocumentBuilder();
            InputSource is = new InputSource(new StringReader(xml));
            Document dDoc = builder.parse(is);
            XPath xPath = XPathFactory.newInstance().newXPath();
            Object result =
                (NodeList)xPath.evaluate(xpathQuery, dDoc, XPathConstants.NODESET);
            NodeList nodes = (NodeList)result;
            for (int i = 0; i < nodes.getLength(); i++) {
                xpathResult = nodes.item(i).getNodeValue();
                System.out.println(xpathResult);
        } catch (Exception e) {
            e.printStackTrace();
        return xpathResult;
Thanks,

Problem with running sample code from XML Schema Processor for Java

Hi there,
I downloaded the XML Schema Processor for Java and tried it out. Unfortunately, it failed at the first step. FYI, I included all xmlparserv2.jar and xmlschema.jar in my classpath.
I compiled XSDSample.java with a warning: XSDSample.java uses a deprecated API. Recompile with "-deprecation" for details. There was no problem with compiling XSDSetSchema.java.
When I tried to run report.xml by typing java XSDSample report.xml, I got Parsing report.xml
NonParserException: null.
I guess that report.xml from the sample is not valid.
Could any one give me a hint? Any suggestion would be greatly appreciated.

Is XML-SQL Utility for Java run on Client Side?

A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?

Set JDK_HOME to the directory where you install your JDK (Java Development Kit).
So instance, I've install JDK1.1.8 on my
C drive so
set JDK_HOME=c:\jdk1.1.8;c:\jdk1.1.8\bin

Here's an example that ships with
the XSQL Servlet release 0.9.8.6
(due out any day now on OTN!!)
With this set of types and object view
you can insert documents like the
example at the end that is REM'd out.
drop view department;
drop type dept_t;
drop type emp_list;
drop type emp_t;
create or replace type emp_t as object (
empno number,
ename varchar2(80),
sal number
create or replace type emp_list as table of emp_t;
create or replace type dept_t as object (
deptno number,
dname varchar2(80),
loc varchar2(80),
employees emp_list
create or replace view department of dept_t
with object OID (deptno)
as select deptno, dname, loc,
cast(multiset(select empno, ename, sal
from emp
where emp.deptno = dept.deptno
) as emp_list ) employees
from dept;
create trigger department_ins
instead of insert on department
for each row
declare
emps emp_list;
emp emp_t;
begin
-- Insert the master
insert into dept( deptno, dname, loc )
values (:new.deptno, :new.dname, :new.loc);
-- Insert the details
emps := :new.employees;
for i in 1..emps.count loop
emp := emps(i);
insert into emp(deptno, empno, ename, sal)
values (:new.deptno, emp.empno, emp.ename, emp.sal);
end loop;
end;

Compile build.xml with Ant for web service with annotations

Hi Friends,
I have a web service with annotations, using javax.annotation.PostConstruct, and javax.annotation.PreDestroy.
I have a build.xml to create a EAR for this web service.
When I run the ant task, the build complete successfully but the .war file cannot be deployed on the WLS server. Taking a closer look, I see that the required files such as, webservices.xml, weblogic.xml, weblogic-webservices.xml, Provision.wsdl files are not generated.
Following is the build.xml file:
<?xml version="1.0" encoding="windows-1252" ?>
<project default="jwsc">
<property file="build.properties"/>
<property name="weblogic.jar.classpath"
value="C:/bea_jDev/wlserver_10.3/server/lib"/>
<property name="oimclient.jar.classpath"
          value="C:/_data/Project_Dc/OIM_jars" />
     <property name="com.jar.classpath" value="C:/JDeveloper/mywork/Service_Test/lib" />
<taskdef name="jwsc" classname="weblogic.wsee.tools.anttasks.JwscTask">
<classpath>
<path id="weblogic.classpath">
<pathelement path="WEBLOGIC_HOME"/>
<fileset dir="${weblogic.jar.classpath}">
<include name="**/*.jar"/>
</fileset>
</path>
</classpath>
</taskdef>
<target name="all" depends="clean,build-service,deploy"></target>
<target name="build-service">
     <jwsc srcdir="${src.home}" destdir="ear_directory" >
<classpath>
<path id="oim.classpath">
<pathelement path="OIM_HOME"/>
<fileset dir="${oimclient.jar.classpath}">

</jwsc>
</target>
<target name="deploy">

</target>
<target name="clean">
<delete dir="output" />
</target>
</project>
Can you please point out what else is to be done and where exactly am I going wrong in writing the build.xml file.
Let me know if some else information is required.

This is what I get when I run the ant task:

XML-25004: Could not acquire a database connection named: gksconnection

HI Gentlemen,
I am trying to build up an XSQL page with a query against an XMLTYPE table, to display the contents using a stylesheet. I have set up an IDE connection, the test was successful. Now I would like to start the page just to see if it works altogether. Now without a stylesheet, only that the page executes. And I am constantly running into
XML-25004: Could not acquire a database connection named: gksconnection
I entered the connection in the XSQLConfig file by manual editing--it did not help. Well, there is some stuff in the forum about setting some preferences for OC4J, but in my version of JDeveloper only Weblogic Server is available. So I am prevented from clearing the cause of the problem.
My JDeveloper is a Studio Edition Version 11.1.1.3.0, Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660.
Please help me if you can.
Many thanks in advance,
kind regards from
Miklos HERBOLY

Sorry, I found a solution in My Oracle Support which will suffice.
Thank you very much

When / why use XML to store data instead of database table ?

Hi All,
I still not use XML much in applications and don't know much about its utilization.
I read here and there about storing data as XML instead of into database tables.
- could any body please tell me when / why use XML to store data instead of database table ?
e.g : store inventory per warehouse in XML format. ?
- What is the other cases or reasons of extracting database records into XML or vice versa ?
- is there any good pdf on this ?
Thank you for your help,
xtanto

It depends entirely what you want to accomplish with the 'XML in the database'. There are basically 3 independent methods: As CLOB, as XMLType views or as native XMLType 'columns'
Each method has advantages and disadvantages, especially in the performance vs purpose tradeoff.
The Oracled Press book "Oracle Database 10g XML & SQL Design, Build, & Manage XML Applications in Java, C, C++, & PL/SQL" is highly recommended for anyone interested in Oracle and XML. http://books.mcgraw-hill.com/getbook.php?isbn=0072229527&template=oraclepress

Generate xml source file for Oracle Order Capture Print Quote

Hi,
I am new to xml and need to work on creating templates for Print Quote.
I am trying to generate the xml source file for which I enabled the report in system administrator and set the output to XML and assigned to Quoting Reports responsiblity. I then assigned XML Report Publisher to the same responsiblity.
I ran the report (Print Quote) and then I am trying to run the XML Report Publisher but I cannot get the request id in the list of values.
I am able to generate xml source file for other reports like Printed Purchase Order etc.,
The view output for the (Print Quote) report is as follows:
<?xml version="1.0" ?>
- 
<ASOPQTER />
How do I get the xml source file? Or are there seeded templates that I can use to create more templates? Any help would be appreciated. Thanks Ravi

Hi, I am in the same position - did this issue ever ger resolved by anyone. I have done a few XMLP reports successfully now using the Word add-in, but customising the Quote output differs from other standard reports.
If you look at the data definition for Quote it is a 'dummy' definition and has no XML file attached. Does anyone know how I can get the XML format for the report output?
Also the template uses XSL-FO ?!?!?! rather than RTF - not sure how to work with this, the Oracle docs are not very helpful in this regard either.
Has anyone successfully managed to customise the Quote print report? Many thanks,
Roger
