XML File Generation

How we can generate XML file using Oracle PL/SQL!!
We have oracle supplied packages for this!!! Which is preferable for printing table data into XML file!!!!
DBMS_XMLDOM
DBMS_XMLGEN
DBMS_XMLPARSER
DBMS_XMLQUERY
DBMS_XMLSAVE
DBMS_XMLSchema
DBMS_XMLStore
UTL_FILE
Thanks

There may be several alternative ways, but maybe the simplest way around is using object views and spool the data coming -
CREATE TABLE warehouse_table (
WarehouseID NUMBER,
Area NUMBER,
Docks NUMBER,
DockType VARCHAR2(100),
WaterAccess VARCHAR2(10),
RailAccess VARCHAR2(10),
Parking VARCHAR2(20),
VClearance NUMBER );
INSERT INTO warehouse_table
VALUES(5, 103000,3,’Side Load’,'false’,'true’,'Lot’,15);
CREATE VIEW warehouse_view OF XMLTYPE
– XMLSCHEMA “http://www.oracle.com/xwarehouses.xsd”
– ELEMENT “Warehouse”
WITH OBJECT ID
(extract(OBJECT_VALUE, ‘/Warehouse/Area/text()’).getnumberval())
AS SELECT XMLELEMENT(”Warehouse”,
XMLFOREST(WarehouseID as “Building”,
area as “Area”,
docks as “Docks”,
docktype as “DockType”,
wateraccess as “WaterAccess”,
railaccess as “RailAccess”,
parking as “Parking”,
VClearance as “VClearance”))
FROM warehouse_table;
SELECT VALUE(e) FROM warehouse_view e;
VALUE(E)
<Warehouse><Building>5</Building><Area>103000</Area><Docks>3</Docks><DockType>Si..

Error in XML file generation :240416

Hi All,
I am facing problem with XML file generation.
Steps:
1. Source-->Query Transform and maintained Nested Stucture
2. Generated XML fomat from query transform
3. Created XML format file
4. Make XML format as target and given XML generate path
source table-->Query(nested structure)-->XML Format
when I validate the job no errors found.
Note: XSD file is in Local mechine and XML file will be generated in SFTP.
Prooblems:
1. Getting below error
The input XML refers to file which is not part of the definition of this XML Schema format. Check your schema and XML files,
and check that the root element in the XML file corresponds to the root element in the XML Schema
Validate your XML Schema using external schema validators (found at w3.org)
Thanks,

Hi,
I think issue Because in your Query Transform output the Root element is Query and XML target is having some other root element. Make the Query trasform name similar to root element and try...

Basic doubt about XML file generation

Hi,
I am new to Java. I am facing some trouble designing and implementing a particular problem involving XML files.
Problem:
I have an XML file which contains a set of properties and their default value. What I need to do is to read another file/stream which will have name=value strings and then, for all the names that I find there, change default value to current value. These names can appear in any order. For example,
<name1 value=default1/>
<name2 value=default2/>
<name3 value=default3/>
And I will get something like "set name3=value3 name1=value1" (This data comes to me from a stream -usb device- and not from a file). Then I should change it to
<name1 value=value1/>
<name2 value=default2/>
<name3 value=value3/>
What is the best possible way to do this in Java? This has to go into an embedded system so it will be nice if it can be done with minimum memory and less processing power.
I am currently reading J2EEtutorial (1.4). I have not read much. But I am confused if I should be using SAX, DOM or XSLT. To speak the truth, I don't even know the difference between all those. Any help will be greatly appreciated.
Thanks & Regards,
Suseelan

Use a DOM parser to parse the original XML.
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
Document document = domBuilder.parse( inputStreamToFile );Then read in the contents from your USB stream into say an array or Vector. Then go through each child node in the domBuilder class, get the nodes name and see if it's in the Vector of objects from the USB stream. If it is, then replace the "Value" attribute in the dom node with what is in the Vector.
Make sense?

Web.xml file generation problem

Hi,
I am trying to create web.xml file automatically using "java weblogic.marathon.ddinit.WebInit
" command.
I got the following message in the command prompt:
Found Web components. Initializing descriptors
filters=0 servlets=0 tags=0
Above command is creating the web.xml and weblogic.xml files but it is not including
the servlet-mapping information. why?
Thanks,
Prakash

It doesn't look like it found any servlets. You'd have to show me your
files if I'm to understand what's going on.

Wait XML File Generation and Present in APEX

Hi All,
I need advice on how can I implement following -
I will be creating Input XML file using database procedure called from APEX, which will then go and executed the call using web services and create output XML file in one of the output directory. What I need help is -
1. Once execute the initial call, then I need to be keep looking for file under output directory. Once the file is generated then I can show it on APEX, but I would like to know how can I implement, so continuously watch the directory for the file and as soon as file generated pick that file and present on APEX and stop watching directory for file.
2. Also APEX will be used by many users concurrently, so how can I create and direct unique file for their own sessions, so myfile should not go to another user?
Please advice

There are lots of thread on ingesting XML and generating XML in this forum. Have a read through some of them and you should get some ideas on where to start. In particular look for threads on rcreating elational views of XML documents and using the SQL/XML Operators

XML file generation in Java

Hello,
I'm using XML files to communicate two systems. The XML files fulfill a W3C Schema.
I want to know if there is any Java library, API or something like this, to generate automatically XML files that fulfill a schema, giving the schema file and the data to fill the XML file.
Thanks,
Laura.

Hi Keith
11g uses the EPG so the images are stored in the database, however are also accessible as a webfolder. This is the same as (or very similar to) XE which I've previously successfully installed this on. The files have been uploaded to the images directory as I'm able to reference /i/sample.html in the iframe successfully. I've never needed to change the .xml file and run apxldimg script, a simple copy and paste has always worked. However, I will try this just to make sure.
Hi Denes
I've tried putting in the absolute path of the directory, which I assume you mean the full path i.e. http://localhost:8080/images/charts_library. But this makes no difference. I know there are differences with 11g, the EPG and that you have to open http://localhost:8080/images/ as a web folder rather than http://localhost:8080/i/ to access the files in the images directory. However, the database that your example application on http://htmldb.oracle.com is running on is an 11g database. It's running 11.1.0.6.0 the same as my database, so it must be possible and by the fact you didn't know this I assume you didn't need to make any changes to make it work!

Datalink sequence method (XML file generation problem using Rdf)

Hi All
I want to Generate XML File using RDF , Here i used 4 datablocks and i lilnked each datablock with datalink like 1 to 2, 1to 3 and 1 to 4 respectively. while executing the report it choosing only one link like 1 to 2 and writting the data in the file for the same. its not touching 3rd and 4th datablocks I need to have data for all the blocks that are available.
One more thing i want to close each blockonce the data is written in the file.But in this case the tags get open wites data goes to the other block write the data for this block come back to the first block and closes the block.
eg: <Start>
<First block>
<Second block>
<Third Block>
</Third block>
</second block>
</First block>
</Start>
My requirment is
<start>
<First block>
</First block>
<Second block>
</Second block>
<Third Block>
</Third block>
</Start>

You might want to look at the SQL/XML operators XMLAGG, XMLELEMENT, XMLFOREST, XMLATTRIBUTES. They provide you with fine grained control over the XML generated.

Automatic xml file generation

parsing xml file and then getting data from xml is ok but is there any api that support xml file generatoion from data itself
help plz

JDOM has an XMLOutputter.
DOM Level 3 allegedly supports outputting from the DOM itself.
However if you don't want to use JDOM, and you don't have access to DOM Level 3, there is a way to do it using transformers. I'm not sure if this is a trick or whether it's considered the standard way to do it.
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
Document dom; // this is what you want outputted
OutputStream stream; // this is where you want it outputted
Transformer identity = TransformerFactory.newInstance().newTransformer();
identity.transform(new DOMSource(dom), new StreamResult(stream));Note that it's not actually much code if you keep the identity transform around for reuse. JDOM's approach is a lot simpler though. :-)

How to suppress ?xml version = '1.0'? in XML file generation thru PLSQL?

Hi,
I am using
1. dbms_xmlgen.newContext to get the information from table.
2. After that I am using dbms_lob.createtemporary
3. Then I am using dbms_xmlgen.getXml
4. Finally I am using dbms_xmlgen.closecontext
I am using the above four steps to repatedly taking records from different tables.
My requirement is : Each and every time I am getting the <?xml version = '1.0'?>.
How to suppress <?xml version = '1.0'?> ?
Regards
Srini

Hi,
Use DBMS_XMLGEN.getXMLType to retrieve the XML data into an XMLType variable.
Then, with getClobVal method, you can convert it to CLOB :
SQL> DECLARE
2    v_xml XMLType;
3    v_lob CLOB;
4 BEGIN
5    v_xml := dbms_xmlgen.getXMLType('select * from scott.emp where rownum = 1');
6    v_lob := v_xml.getClobVal();
7
8    dbms_output.put_line(v_lob);
9 END;

The same query is running fine with apps user. What are the objects privileges required for the custom module user?.

I have found resolution for this.
1. Created the Public Synonym for the following Apps user Java Class objects:
/109a284b_OracleXMLStaticQuery
/12249373_OracleXMLStaticQuery
/c33162ba_OracleXMLStaticQuery
2. Execute privilege for Apps.DBMS_XMLQUERY to custom application user.

How do I modify invoice request xml file by adding posting date?

Hi,
We import customer invoice requests via xml files from an external data source. Currently the standard SAP xml file does not include the posting date, and invoices enter SAP with a blank posting date. When the invoice is released, the posting date is taken from the invoice date.
Due to our month end processes, we have hundreds of invoice requests every month where we do not want posting date to equal the invoice date, and for each of those invoices the posting date is manually entered one invoice at a time during the release process. This is very time consuming.
We would like to build functionality in our external system to create the posting date at the xml file generation stage. Could anyone let us know the following:
- what is the name of the posting date field on invoice requests (invoice documents)?
- where would we place the additional script in the xml file?
I'm attaching one of our current xml files (which already contains one section that has been customized)
Your suggestions would be appreciated.
Thanks,
Kerstin

Kerstin,
The closest i could find in the WSDL of the Manage Invoice Request Web Service that handles this integration is "<ProposedInvoiceDate>" or possibly even "<ProposedDeviatingPostingdate>", both of which sit directly under the <CustomerInvoiceRequest> element.
For more information, go to the Service Explorer, find the ManageInvoiceRequestsIn Web Service, download the WSDL, and open it in SOAP-UI or something similar. This way you can see all the fields that you can write to, which is where i found these two elements.
