As I recall from my 8i days (it's been many years), the only way to do this is to install the XML XDK. From http://www.oracle.com/technology/tech/xml/xdk/xdk_java.html, it says "The Oracle9i versions of the XDK can also be used to build applications designed to interface with Oracle8i databases." I had thought the 10g version could do that as well but I'm not seeing it now.
Since XMLType was not part of 8i, you will need to use PL/SQL to take your Select statement results and build them into a DOMDocument structure.
Hope that helps.

Nested XML structure from Oracle

Using the SQL Adapter i BizTalk, calling a SQL Stored procedure on a MS SQL DB, I can get a nice nested XML structure using p JOIN ii and FOR XML AUTO, like this
<p code="DK003">
<ii stamp="2013-01-14T10:27:38.790"value="180.702052"price="184.000000">
<d Dividend="2.50"DividendDate="2012-03-29T00:00:00" />
</ii>
<ii stamp="2013-01-14T10:27:38.790"value="181.702052"price="14.000000">
<d Dividend="2.50"DividendDate="2012-03-29T00:00:00" />
</ii>
</p>
How can I get the same on Oracle ??

Hi E.,
I guess this an XML namespace issue. I'm creating XmlForms-style documents and had to add an XML namespace to my root element to make them visible as such:
Namespace xf = Namespace.getNamespace("xf", "http://www.sapportals.com/wcm/app/xmlforms");
root.addNamespaceDeclaration(xf);
So what I'd suggest to you is reading out the IResource and treating the content as XML:
Document document = new SAXBuilder().build(content.getInputStream());
Element root = document.getRootElement();
Namespace xf = Namespace.getNamespace("xf", "http://www.sapportals.com/wcm/app/xmlforms");
root.removeNamespaceDeclaration(xf);
Hope this helps!

Christian

Generating multi-level xml in oracle

Hi,
I want to create a multi-level XML structure from oracle, is there a way?
Presently oracle provides DBMS_XMLQUERY and XMLGEN package to generated XML structure given a query. But the structure so generated is of single level. That is say I use
select XMLGEN.getXML('select * from employees') from dual;
the output is
<EMPLOYEE>
<ROW num="1">
<NAME>Mark</NAME>
<TEL>451-638191</TEL>
</ROW>
</EMPLOYEE>
That I call a single level output.
To create a multiple level XML I went in for object type in oracle. But the problem with this is that if I want to have multiple children for a single parent then object types fail. The structure below is not possible with object type.

Then I tried nested tables. Here one needs to create an object type to create a table type. One cannot create a table type out of another table type. So that leavs me with 2 levels
object type
used by
table type
used by
table.
Presently to generated a multi-level output as shown above I'm using cursors and build it in a clob variable.
Is there any other way that one can build a multi-level structure. Or is there a build in package that comes with orace 8i (and higher).

Milton.

Milton,
I was able to generate hierarchical XML from Oracle using object views and XML-SQL Utility (XSU).
Here is a simplified version of my OR schema:
/* Physical spec object */
create or replace type physical_specifications_object as object (
physical_specifications_id number(15),
page_count number(10),
product_id number(10),
four_color_count number(10),
two_color_count number(10),
table_count number(10),
binding_type varchar2(100),
height varchar2(20),
width varchar2(20)
/* Market object */
create or replace type market_object as object (
market_id number(15),
master_class_name varchar2(50),
market_name varchar2(100),
market_type varchar2(100),
market_description varchar2(500),
level_rank varchar2(15),
market_code varchar2(100),
product_id number(10)
/* List of markets */
create or replace type market_table as table of market_object;
/* Market object view */
create or replace view market_object_view of market_object
with object identifier (market_id) as
select mkt.market_id,
class.master_class_name,
mkt.market_name,
mkt.market_type,
mkt.market_description,
prod_mkt.level_rank,
mkt.market_code,
p.product_id
from market mkt,
product p,
product_market prod_mkt,
master_class class
where p.product_id = prod_mkt.product_id
and prod_mkt.market_id = mkt.market_id
and mkt.master_class_id = class.master_class_id(+);
/* Feature object */
create or replace type product_feature_object as object (
feature_id number(15),
feature_text varchar2(3500),
feature_type varchar2(100)
/* List of features */
create or replace type product_feature_table as table of product_feature_object;
/* Product object */
create or replace type product_object as object (
product_id number(10),
title varchar2(150),
media_type varchar2(20),
standard_number varchar2(100),
physical_specifications physical_specifications_object,
markets market_table,
product_features product_feature_table
/* Product object view */
create or replace view product_object_view of product_object
with object identifier (product_id) as
select p.product_id,
p.title,
p.media_type,
p.standard_number,
physical_specifications_object(spec.physical_specifications_id,
spec.page_count,
spec.product_id,
spec.four_color_count,
spec.two_color_count,
spec.table_count,
spec.binding_type,
spec.height,
spec.width),
cast(multiset(select *
from market_object_view mkt
where mkt.product_id(+) = p.product_id) as market_table) as markets,
cast(multiset(select f.feature_id, f.feature_text, f.feature_type
from feature f
where f.product_id = p.product_id) as product_feature_table) as product_features
from product p,
physical_specifications spec
where p.product_id = spec.product_id(+)
The objective is to generate XML for a product list with all the product subelements. The simple query "select * from product_object_view" when fed to the XML-SQL utility generates multi-level SQL. Note that Oracle 8i allows up to two level collection nesting in object types. Oracle 9i removes this limitation.

Generating multi-level XML in Oracle 8i using XML-SQL utility

Oracle 8i has a limitation when it comes to the object types. Only one-level nesting of collection is allowed. Oracle 9i apparently removes this limitation.
I am trying to generate XML for a hierarchical (conceptually) structure. To do that I am using XML-SQL utility (XSU) running agains an object view build on top of the relational data. The problem is the limit to onelevels of colelction nesting. Oracle 8i gives you a way to create a view with more levels of nesting by using references (REF). The problem is that when XSU runs agains a view with the references, it inserts the references into the XML document (instead of dereferencing them).
Is there a way to generate XML with Oracle 8i with more than two levels of collection nesting?
Thank you.
Michael

Nested XML with XSU

I have data in an Oracle8i-database and will use Java to export
it to XML. I’m trying to use XML Developer’s Kit’s (XDK’s) XML
SQL Utility’s (XSU’s) OracleXMLQuery class. But I’ve problems to
get the nested XML-structure I need!
Oracle says there’s two good ways to do this:
“Source Customization
This category incompases customizations done by altering the
query or the database schema. Among the simplest and the most
powerful source customizations are:
* over the database schema, create an object-relational view
which maps to the desired XML document structure.
* in your query, use cursor subqueries, or cast-multiset
constructs to get nesting in the XML document which comes from a
flat schema.”
They then have an example how to create an object-relational
view. But this is done with an empty database, and I already
have tables with data so I don’t know how to do this.
I’ve tried with some simple subqueris like
SELECT name, id,
(SELECT COUNT(*) FROM order o WHERE c.id = o.id) AS
NumOfOrders
FROM cust c
But it adds just another colum.
Could somebody help me or direct me to some resource, please?
Thanks!

which maps to the desired XML document structure.
* in your query, use cursor subqueries, or cast-multiset
constructs to get nesting in the XML document which comes from a
flat schema.”
They then have an example how to create an object-relational
view. But this is done with an empty database, and I already
have tables with data so I don’t know how to do this.
I’ve tried with some simple subqueris like
SELECT name, id,
(SELECT COUNT(*) FROM order o WHERE c.id = o.id) AS
NumOfOrders
FROM cust c
But it adds just another colum.
Could somebody help me or direct me to some resource, please?
Thanks!

Database data to nested xml structure

Hi All,
I need to convert the data in the oracle database to nested xml tree structure as below:
Data in the database is in the following structure:
1     branch1     13-JAN-11     a.txt
1     branch1     25-JAN-11     b.txt
1     branch1     25-JAN-11     c.txt
1     branch2     20-JAN-11     d.txt
2
XML for the above data should be in the format:
<Root>
<Account_no value="1">
<Desc value="branch1">
<Date value="13-JAN-11">
<Name value="a.txt"/>
</Date>
<Date value="25-JAN-11">
<Name value="b.txt"/>
<Name value="c.txt"/>
</Date>
</Desc>
<Desc value="branch2">
<Date value="20-JAN-11">
<Name value="d.txt"/>
</Date>
</Desc>
</Account_no>
<Account_no value="2">
</Account_no>
</Root>
I am able to get this kind of xml structure using java after storing the database data in a n-ary tree. But it takes more time to execute.
Can this kind of same xml format be achieved using pl/sql programming?
Please help me with your valuable insights.
Thanks,
Alagappan

Hi,
Please always mention your db version (select * from v$version).
Here's one solution using SQL/XML functions :
Sample data used :
create table sample_data
account_no number,
description varchar2(30),
dt          date,
name        varchar2(30)
insert into sample_data values(1, 'branch1', to_date('13-JAN-11','DD-MON-RR'), 'a.txt');
insert into sample_data values(1, 'branch1', to_date('25-JAN-11','DD-MON-RR'), 'b.txt');
insert into sample_data values(1, 'branch1', to_date('25-JAN-11','DD-MON-RR'), 'c.txt');
insert into sample_data values(1, 'branch2', to_date('20-JAN-11','DD-MON-RR'), 'd.txt');
insert into sample_data values(2, 'branch3', to_date('20-JAN-11','DD-MON-RR'), 'e.txt');Query :
SELECT xmlserialize(document
         xmlelement("Root",
           xmlagg(
             xmlelement("Account_no", xmlattributes(account_no as "value"),
               xmlagg(
                 xmlelement("Desc", xmlattributes(description as "value"), dt)
                 order by description
             ) order by account_no
       as clob indent ) doc
FROM (
SELECT account_no, description,
         xmlagg(
           xmlelement("Date", xmlattributes(to_char(dt,'DD-MON-RR') as "value"), name)
           order by dt
         ) dt
FROM (
    SELECT account_no, description, dt,
           xmlagg(
             xmlelement("Name", xmlattributes(name as "value"))
             order by name
           ) name
    FROM sample_data
    GROUP BY account_no, description, dt
GROUP BY account_no, description
GROUP BY account_no
DOC
<Root>
<Account_no value="1">
    <Desc value="branch1">
      <Date value="13-JAN-11">
        <Name value="a.txt"/>
      </Date>
      <Date value="25-JAN-11">
        <Name value="b.txt"/>
        <Name value="c.txt"/>
      </Date>
    </Desc>
    <Desc value="branch2">
      <Date value="20-JAN-11">
        <Name value="d.txt"/>
      </Date>
    </Desc>
</Account_no>
<Account_no value="2">
    <Desc value="branch3">
      <Date value="20-JAN-11">
        <Name value="e.txt"/>
      </Date>
    </Desc>
</Account_no>
</Root>
Here, I used XMLSerialize function with indent option to format the output (available starting with 11g).

Producing nested xml with querying attributes from a nested table

How can one produce nested xml querying columns from a nested table? Looking at the object documentation, I can readily unnest the tables. Using your examples in the book, unnesting is select po.pono, ..., l.* from purchaseorder_objtab po, table (po.lineitemlist_ntab) l where l.quantity = 2;
what if I don't want to unnest and don't want a cursor. I would like to produce nested xml.

Gail,
Although you can use XSU (XML-SQL Util) in 8.1.7, I would recommend that you upgrade to 9i for much better support (both in functionality and performance) of XML in the database. For example, in Oracle9i there are:
- a new datatype - XMLType for storing and retrieving XML documents
- DBMS_XMLGEN package and SYS_XMLGEN, SYS_XMLAGG functions for generating XML document from complex SQL queries
- A pipelined table function to break down large XML documents into rows.
You can check out some examples using SYS_XMLGEN and DBMS_XMLGEN for your specific needs at http://download-west.oracle.com/otndoc/oracle9i/901_doc/appdev.901/a88894/adx05xml.htm#1017141

You could flatten the XML into table style output using XMLTABLE...
WITH t as (select XMLTYPE('

    <POINT>1800</POINT>
    <USER_INFO>

    <USER_INFO>
      <USER_ID>5</USER_ID>
      <TARGET>19</TARGET>

      <TASK>90</TASK>

              PASSING t.xml
              COLUMNS country NUMBER PATH '/REC/COUNTRY'

Just trying to clarify some issues as I try and learn about XML, and specifically how it integrates into the DB.
1 - Is there a way with Oracle tools for me to get an XSD of an existing 9i relational schema? We are not currently using the XML DB, but our middleware developers would like to have an up to date XSD to use for their internal mapping.
2 - Is there any way that I can keep that XSD up-to-date automatically, so I get a new one whenever the schema gets updated?
3 - If I wanted to investigate storing XML docs within the DB in native XML format, I need to have an XML DB, correct? Is this DB construct maintained seperatelly from my "normal" relational schema? or are they kept in sync by Oracle?
I know these may all be real basic questions, but as I said, I'm new to XML and Oracle. I am reading as much as I can, but there are a lot of docs out there.
Thanks,
Mike

Hi
1. On my opinion such a tool doesn't exists. Some parts can be implemented elsewhere, but not as described by you... e.g. with XSU if you specify the parameter "withschema" the XSD of the executed statement is generated. Another example is to use DBMS_METADATA to dump the data dictionary in XML (but not XSD, of course you could write your own XSLT to do this transformation...).
2. -
3. If you use XSD-based tables the XSD and the relational model are stored separately in the data dictionary. Therefore if you change the XSD you have to drop/create the XSD-based table... no schema evolution yet.

Ben,
The following link as some information regarding DOM API and XSQL.
http://asktom.oracle.com/pls/ask/f?p=4950:8:2923508047773696280::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:17309127931717
For XML DB, you may want to create an XMLSchema and build a table off the schema definition. Then use WEBDAV to load the xml into a folder (ie object table) Once the xml is in the database you could build a view for a relational look at the data.
Example from XMLDB Techical White Paper doc.
create or replace view PURCHASEORDER_MASTER_VIEW
(reference, requestor, userid, costcenter,...)
as select extractValue(Value(p),'/PurchaseOrder/Reference'),
extractValue(value(p),'/PurchaseOrder/Requestor'),
extractValue(value(p),'/PurchaseOrder/User'),
extractValue(value(p),'/PurchaseOrder/CostCenter'),...
from PURCHASEORDER p

Spry Menu Using Nested XML Dataset (Spry 1.6)

I have a vertical menu with a few items. One of which is
labeled Products which has submenus. I want to have that submenu
read from a Nested XML dataset. Using a single dataset for one
level in a menu is easy enough, but the subenu will have submenus.
Example Menu:
Home
Company
Products
|-- Product 1
|-- Item 1
|-- Item 2
|-- Item 3
|-- Product 2
|-- Item 1
|-- Item 2
|-- Product 3
|-- Item 1
|-- Item 2
|-- Item 3
|-- Item 4
|-- Product 4
|-- Item 1
|-- Item 2
|-- Product 5
I have been looking for an easy way to use the Spry Nested
XML Dataset to create the Product/Item menu. The number of Products
may vary as well as the number of Items in each Product submenu
(also, some Products may not have Items).
I already have an ASP page that creates the XML data from a
database.
Schema follows (XSD ):
<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="
http://www.w3.org/2001/XMLSchema">
<xsd:element name="products">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="product_type"
maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="type_name" maxOccurs="1"
type="xsd:string"/>
<xsd:element name="type_url" maxOccurs="1"
type="xsd:anyURI"/>
<xsd:element name="product_name"
maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="item_name" maxOccurs="1"
type="xsd:string"/>
<xsd:element name="item_url" maxOccurs="1"
type="xsd:anyURI"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
I have been programming for 17 years but am new to Spry. If
this cannot be done easily with the Spry framework, I'll probably
wind up splitting the XML data into 2 files (Products and Items)
then writing a nested loop and call each by row, but then I have to
find out how Spry Datasets reference XML data. Figuring out how to
call rows from the XML data shouldn't be so bad, but this method
just seems like such a hassle for something that should be easy.
Pseudocode follows:
j=1
i=1 to TotalNumberProducts
display Product i from Products
ItemsExist=true
While ItemsExist
if j > TotalNumberItems | Item j is not for Product then
ItemsExist=false
else
display Item j from Items
j++
Wend
Next
Thanks in advance for any help or direction!

That's exactly what I'm trying to do. However, I implemented
that code and the submenus won't appear. I suspect the submenus
aren't finding the field names from the Nested XML Dataset. The
first level of Product menus work great (this is a submenu of the
overall menu) and correctly identify products that do not have
submenus, so I know it's picking up the number of records in the
Nested Dataset correctly - it just won't display the data in the
next level of menu.

How to construct the where clause for a nested xml target file

Post Author: jlpete72
CA Forum: Data Integration
I'm having some problems getting the desired results creating a multi-level nested xml file. Specifically, it does not seem that the where clause in the child schemas respects values from parent schemas. I'm sure I'm constructing something incorrectly, but am running out of ideas.
I am working with the classic company/order/line hierarchy and there are three levels of output schemas in my target xml file, one for company, order header and order line information.
For testing, I have hardcoded a restriction at the order header line to deal with only one order. But unless I hardcode values into the where clause at the order line level of the schema, all values are returned for orders belonging to the company defined in the company level.
I'm trying a where clause at the order line level similar to:
order_line.customer = order_header.customer and order_line.order_num = order_header.order_num
If the customer has more than one order in the data file, then all orders for that customer are placed in the detail for the order header. Only if I hard code the order number in the where clause do I get only the lines for the order specified in the header section. Not very practical.
What am I missing?

An External Parsed Entity could be used to reference a schema.
In your DTD:
<!ENTITY datamodules SYSTEM "file:///c:/Datamodules/Datamodules.xsd">
Refer the external entity in xml document:
<datamodules>&datamodules;</datamodules>

XML in Oracle 9i (best method to return a xml file from a table query)

Hello.
What is the best method to query a table, or set of tables (that will return thousands of rows) using xml in oracle? (best performance)
I'm currently using DBMS_XMLGen, is there a better method ?

I think, if your talking about generating XML, that you should use XMLElement, XMLForest, etc. to create your XML.
Lets assume that you base is relational data, then maybe the following great example will give you an idea how to do it : Re: Generate XML Schema from oracle tables
As michaels pointed out (did you read the link/ URL given?), the general expectancy is that the packages will be less and less important. So also maintenance wise the XMLElement, etc way will be the best, also for the future, maintainable method.

Generating Deeply nested XML from a flat file

Hi All,
I am working on a MQ to IDOC scenario.
I am getting a flat file as input. I need to convert it into XML( so that XI can understand it).
But conversion is into a "Deeply Nested XML from a Flat File" at sender side (JMS Adapter).
Any inputs on this.
Regards,
Vikas

You can only convert flat file into xml structure with 3 levels.
If you need to convert flat file into deep nested xml structure, you have to do java mapping or xslt or abap mapping. There is a tool, I think it's called conversion agent by itemfield (bought by SAP), which can do pretty everything with conversion. Never used it though.
