Sql/xml - no namespace

Hi
I get a "LPX-00234: namespace prefix "def" is not declared" when i run the SQL/XML code below. It works fine when i run it without the Extract() function. I am using 9.2.0.6.0.
any help is much appreciated. i am running this directly against the database and I have no namespace set up.
select xmlelement(name "ItemDef",
XMLAttributes (a.oid as "OID",a.name as "df.Name"),NULL).extract('/*').getclobval()
FROM xmlview a

Please ignore i am a fool... declared namespace def: in code, so need to declare a def namespace in code. Used workaround
SELECT xmlelement("links", xmlattributes('link1' AS "xmlns:def",'link2' AS "xmlns:xlink"),
rest of code
works now
cheers

How do I create an undeclared namespace node with sql/xml?

I have to interact with a .NET web service that is expecting to have an xml node with an undeclared namespace, i.e. <address xmlns=""> I figured that I could create this by using XMLATTRIBUTES ( '' AS "xmlns") but a null attribute will not be added to the attribute listing. This works fine for other xmlns entries that contain values. Without this undeclared namespace node, the web service reports an Internal SOAP failure message, so I have to include it. Do I have to resort to manually injecting this null attribute via DOM after I produce the xml? I'm using SQL/XML query generate the xml as a view which gives me the entire packet for this document/literal web service OTHER THAN this missing undeclared namespace element.
Any tips/suggestions would be helpful! Thanks a bunch, and have a Happy Holiday Season.

You can use UTL_RAW package.
First, convert string to raw with UTL_RAW.CAST_TO_RAW, then using UTL_RAW.CONVERT to convert raw to utf-8 and finally UTL_RAW.CAST_TO_VARCHAR to get utf-8 string.

Unable to locate Spring NamespaceHandler for XML schema namespace

I am not sure if this is the best practice approach but this is the problem I am ruining into. Below, I explain what I am doing:
1) What I am doing:
=============
Based on the oracle incubator example (http://coherence.oracle.com/display/INCUBATOR/Processing+Pattern+Examples); I am running a server and submitting tasks through a proxy application that submits them to ProcessingPatternConfigurator; let's call my task processReport.
a) my processReport is using spring and ibatis together, I created a utility static class to obtain a spring context and retrieves beans using the following lines ( see exhibit "A1 and A2" below).
b) when my task calls the context and that spring loads, it is failing with the error show in exhibit "B".
I suspect I am missing a lib? I googled the error and searched you site but could find a meaningful discussion on it. I guess my question is if this is not the best approach, how do I integrated with spring initializing beans and setting up ibatis framwork, providing beans and database access through Ibatis for each task ruining on the grid (processReport).
thanks
A1) processReport (submitted in the grid) uses this line
AbstractXmlApplicationContext ctx = (AbstractXmlApplicationContext) AmrContextUtil.getInstance();
          System.out.println("Classpath loaded. Executing Report...");
          ReportProcessor repProcessor = (ReportProcessor) ctx.getBean("reportProcessor");
A2) Here is the AmrContextUtil:
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public final class AmrContextUtil {
     private static AbstractApplicationContext ctx = null;
     public AmrContextUtil() {
          super();
     public final static synchronized AbstractApplicationContext getInstance(){
          if (ctx == null){
               ctx = new ClassPathXmlApplicationContext("classpath:config/applicationContext.xml");
               setCtx(ctx);
          return ctx;
     public final static synchronized AbstractApplicationContext getCtx() {
          return ctx;
     public final static synchronized void setCtx(AbstractApplicationContext ctx) {
          AmrContextUtil.ctx = ctx;

My guess is that something is broken in the configuration of the cacheServer and its not finding
all of the dependencies that your process pattern application needs. Probably the best way
to debug this stuff is to define a static main in your runnable task which will make the call
to the run() method and invoke it as the main class using the identical settings (classpath,
run directory) that you are using to launch the Coherence cache server.

?xml version = '1.0' encoding = 'ASCII'? pl/sql xml parser

When ever I parse a document which has the
<?xml version = '1.0' encoding = 'ASCII'?> tag as the first line hangs the pl/sql xml parser . If I remove the "encoding = 'ASCII'" from the file everything works fine ! What is the problem ?
version 8.1.6 / plsql parser v2 / hpux 11x
Here is the input file
<?xml version = '1.0' encoding = 'ASCII'?>
!--- This is a comment -->
<person>
<employee>
<lastname>GHANTASALA</lastname>
<firstname>SREE</firstname>
<age>32</age>
</employee>
<employee>
<lastname>TAMATAM</lastname>
<firstname>SATISH</firstname>
<age>30</age>
</employee>
</person>
Here is my program
declare
p xmlparser.parser;
doc xmldom.DOMDocument;
dir varchar2(100) := '/apps/oracle/drugstore';
errfile varchar2(30) := 'err.txt' ;
inpfile varchar2(30) := 'person.xml';
nl xmldom.DOMNodeList;
len number;
n xmldom.DOMNode;
new_node xmldom.DOMNode;
node_name varchar2(100);
node_value varchar2(100);
begin
-- new parser
p := xmlparser.newParser;
-- Set some characteristics
xmlparser.setValidationMode(p, FALSE);
xmlparser.setErrorLog(p, dir| |'/'| | errfile );
xmlparser.setBaseDir(p, dir);
-- parse input file
xmlparser.parse(p, dir| |'/'| |inpfile);
-- get document
doc := xmlparser.getDocument(p);
-- get all elements
nl := xmldom.getElementsByTagName(doc, '*');
len := xmldom.getLength(nl);
dbms_output.put_line('Length='| |len);
-- loop through elements
for i in 0..len-1 loop
n := xmldom.item(nl, i);
node_name := xmldom.getNodeName(n);
-- get the text node associated with the element node
n := xmldom.getFirstChild(n);
if xmldom.getNodeType(n) = xmldom.TEXT_NODE then
node_value := xmldom.getNodeValue(n);
if node_name='lastname' then
dbms_output.put_line('The value you are looking for is -->:'| |node_value);
if node_value = 'GHANTASALA' then
xmldom.setNodeValue(n,'TEST2');
end if;
end if;
end if;
end loop;
new_node := xmldom.makeNode(doc);
xmldom.writeToFile(new_node, dir | |'/'| |'mod.xml');
end ;
null

The encoding header is actually generated by
by the following piece of code in my pl/sql program .
new_node := xmldom.makeNode(doc);
xmldom.writeToFile(new_node, dir | |'/'| |'mod.xml');
Since this is a document created by the pl/sql parser, I assume there is some meaning to it !
Also why is it hanging ? PL/sql parser should tell me that it is not a valid string !

There is no such limit on our Parser for PL/SQL. Could you
perhaps be using the PLXML Utilities? If you are you might try
our PL/SQL Parser instead.

JMS Adapter getting xml without namespace

Hello,
We're using BPEL 10.1.3.4 and we need to integrate a legacy system with a new one. The legacy system writes in a JMS queue a simple xml message without namespaces (following although a specific schema). When in BPEL I try to get this xml I cannot access its elements and I'm getting errors like the following:
variable/ expression is empty
Which seems normal as bpel tries to access the element using namespaces.
I found this thread which seems to be the same issue Re: writing XML without namespace? but I cannot actually understand the approach.
Any help will be really usefull!
Thank you!

Hi,
Did the solution mentioned in the other thread worked for you? I am having the exact problem.
Thanks.

Can I use SQL/XML feature on EVERY Oracle DB?

I appreciate the SQL/XML as described here:
http://www.oracle.com/technology/oramag/oracle/03-may/o33xml.html
But I wonder if I can use these commands on EVERY Oracle DB.
Do I have to prepare/setup an existing DB in any way for receiving such SQL/XML commands ? Or do I have to enable this feature/install an Add-On?
Can I use this feature even with the Express Editions ?
Peter

SQL/XML appears in 9.2.x and later. Not all of the operators in the current (11g) product are available in earlier releases. Please check the SQL reference guide for a particular version. However that article is quite old so it probably only refers to the ones in 9.2.x

Strange Behavior with SQL/XML

Our University have had for quite some time now a rather difficult situation with a very significant course handbook web site that creates HTML based on database XSL transformation of XML content generated with SQL/XML. The database is 10.2.0.2.0. The HTML is passed via a distributed database link to an Oracle Portal dynamic portlet for display. Some of the derived XML originates from XML Schema registered instance documents and some from relational storage.
Let me explain. Occasionally after a period of operating (could be one week, sometimes even less) we will experience a problem whereby our derived XML content (just prior to PL/SQL database XSL transformation) will develop a parsing problem. Once this happens to one XSL transform of a course then subsequently it happens for every course viewed/transformed there-after.
Recently I experienced the problem and then added the XMLNS argument to the extract function. That seemed to fix things and I thought I had it licked.
Today we started to get the same problem again. The error reported was:
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00242: invalid use of ampersand ('&') character (use &)
Error at line 1
Now this might have been reasonable for one course. But every course reported the same problem there-after without fail. I managed to fix the issue but in a way that really doesn't seem to make sense. What I did was to alter the SQL/XML statement by adding in an extra XMLEMENT and then to recompile the function that returns an XMLTYPE based on the execution of the SQL statement. After compiling the function everything returned to normal.
This doesn't seem to make sense.
I am pretty desperate for help on this. I really don't know how to progress the solution. I don't get much joy from Oracle Support as our application covers too many high tech areas. This is really shaking confidence in our organization's use of Oracle technology.

Hi Mark.
We've isolated the problem a bit more now and there is a support SR (6089662.994). At this stage we are unable to reproduce - I am testing out an export though. The problem only occurs when a certain condition has been reached. Once that happens then extraneous characters are produced in the XMLTYPE feed returned by a function. We are not at all sure about how to make this condition occur. This doesn't just happen with one SQL/XML cursor - I've seen it happen with 3 different cursors. All are located in the same function that returns an XMLTYPE.
We are convinced the problem lies with one or more SQL/XML cursors located in the same function. Once one of these cursors malfunctions it will produce XML that is not well formed OR on occasion has content omitted but is well formed (there often seem to be extraneous characters). When the XML content is not well formed then the parsing stage (dbms_xmlparser.parseclob(myparser, xml_clob)) of XSL transformation crashes. This error then propagates to the dynamic portlet in Oracle Portal thus removing the content on the page. This happens for every execution of the cursor while the condition manifests, the only difference between calls being bind variables.
The interesting thing is that the error if left to itself will eventually stop. The cursor seems to right itself eventually. On the last occurrence, the problem commenced at 4.30am and went for 3.5 hrs and then seemed to right itself.

Sql/xml - powerful tool for complex reports

I just want to share euphoria...
HTMLDB itself provides powerful ways how to control the design of the page - various types of regions, page types, templates...
Nevertheless sometimes you need even more precise control over the content and format of the displayed page. The combination of SQL/XML and HTMLDB solves it in very elegant way.
- create page with common SQL report region.
- prepare the SELECT gathering the data to be displayed
- prepare another SELECT using SQL/XML functions adding HTML formating tags upon the first select.
Example:
select
XMLTYPE.getStringVal(
XMLElement("table",
XMLAttributes('5' as cellpadding),
XMLConcat(
XMLElement("tr",
XMLElement("td",
XMLAttributes('left' as align, 'top' as valign),
XMLElement("a",
XMLAttributes(provider_url as href),
XMLElement("img",XMLAttributes(provider_icon as src, provider_name as alt, provider_name as title))
XMLElement("td",
XMLAttributes('left' as align, 'top' as valign, '150' as width),
XMLElement("a",
XMLAttributes(event_url as href),
XMLElement("div",XMLAttributes('font-weight:bold; font-style:normal; font-size:10px; ' as style), event_name_part2)
XMLElement("div",XMLAttributes('font-weight:normal; font-style:normal; font-size:10px; ' as style), event_name_part1)
XMLElement("td",
XMLAttributes('right' as align, 'top' as valign),
XMLElement("div",
XMLElement("a",
XMLAttributes( edit_url as href),
XMLElement("img",
XMLAttributes( '#IMAGE_PREFIX#ed-item.gif' as src, '14' as width, '14' as height, 'Editovat článek/pořad' as alt, 'Editovat článek/pořad' as title)
XMLElement("div",
XMLElement("a",
XMLAttributes( delete_url as href),
XMLElement("img",
XMLAttributes( '#IMAGE_PREFIX#wastebasket.gif' as src, '16' as width, '16' as height, 'Smazat článek/pořad' as alt, 'Smazat článek/pořad' as title)
) as event_description
from (select
case
when EVENT_PROVIDER_TYPE='Magazine' then set_1 || ' ' || set_2 || ' ' || set_3 || ' ' || set_4
when EVENT_PROVIDER_TYPE='Radio' then set_1 || ' ' || set_2 || ' ' || set_3 || ' ' || set_4
when EVENT_PROVIDER_TYPE='Author' then set_2
end as event_name_part1,
case
when EVENT_PROVIDER_TYPE='Magazine' then set_5 || ' ' || set_6
when EVENT_PROVIDER_TYPE='Radio' then set_5 || ' ' || set_6
when EVENT_PROVIDER_TYPE='Author' then set_1
end as event_name_part2,
events.url as event_url,
my_events.issue_date,
providers.icon_path as provider_icon,
providers.provider_name,
case
when substr(upper(providers.www_address),1,7)<>'HTTP://'
then 'http://' || providers.www_address
else providers.www_address
end as provider_url,
'f?p=' || v('APP_ID') || ':2:' || v('SESSION') || '::NO:16:P2_EVENT_ID,P2_EVENT_NAME:' || events.event_id || ',' || events.event_name as delete_url,
'f?p=' || v('APP_ID') || ':35:' || v('SESSION') || '::NO:35:P35_SELECTED_EVENT_ID,P35_SELECTED_EVENT_NAME:' || events.event_id || ',' || events.event_name as edit_url
from my_events
join events on my_events.event_id=events.event_id
join providers on EVENTS.PROVIDER_ID= PROVIDERS.PROVIDER_ID
where my_events.user_id=:IAL_USER_ID
order by my_events.issue_date desc)
P.S. It's cool to use XMLAGG function in combination with GROUP BY clause - it enables you to easily display list of strings as a single filed on the formular....

You will be able to use our XSL Processor to format into HTML or
CSV once it is released next month. Adobe is sponsoring a
context for a PDF engine for XML.

Creating optional elements using SQL / XML functions

Hi,
I am struggling with some SQL / XML functionality in order to create some optional elements in a XMLType.
I have one table with data to be generated into an XML document. The table looks like this (only the attributes related to the problem are shown):
msg_id (pk)
geslacht_hoofdverzekerde
geboortedatum_hoofdverzekerde
geslacht_medeverzekerde
geboortedatum_medeverzekerde
I have to create an XML document that looks like this:
<ber:rekenparameters>
<ber:verzekerde>
<ber:codeRelatierol>HVZ</ber:codeRelatierol>
<ber:geslacht>M</ber:geslacht>
<ber:datumGeboorte>01-01-1960</ber:datumGeboorte>
</ber:verzekerde>
<ber:verzekerde>
<ber:codeRelatierol>MVZ</ber:codeRelatierol>
<ber:geslacht>V</ber:geslacht>
<ber:datumGeboorte>01-01-1961</ber:datumGeboorte>
</ber:verzekerde>
</ber:rekenparameters>
Where <ber:codeRelatierol> is hard coded: i.c. of hoofverzekerde 'HVZ' in case of medeverzekerde 'MVZ'.
Geslacht en datumGeboorte are taken form the table.
The element <ber:verzekerde> is obligatiry for hoofdverzekerde but optional for medeverzekerde: only in case geslacht_medeverzekerde and geboortedatum_medeverzekerde are not null this 2nd <ber:verzekerde> element has to be added.
I created the next SQL (I skipped some stuff in order to focus on the problem):
CREATE OR REPLACE
VIEW dps_v_berekening_berichten
AS
SELECT msg_id as msg_id
, XMLElement( "ber:berekening"
, XMLAttributes( 'http://www.w3.org/2001/XMLSchema-instance' AS "xmlns:xsi"
, 'http://www.mycompany.nl/berekenen' AS "xmlns:ber"
, 'http://www.mycompany.nl/berekenen http://www.mycompany.nl/berekenen/berekening.xsd' AS "xsi:schemaLocation"
, XMLElement( "ber:nummerRekenRegel"
, XMLAttributes( 'http://www.mycompany.nl/berekenen' AS "xmlns:ber" )
, 1
, XMLElement( "ber:rekenparameters"
, XMLAttributes( 'http://www.mycompany.nl/berekenen' AS "xmlns:ber" )
, XMLElement( "ber:codeEvolutie" ) -- Empty
, XMLElement( "ber:verzekerde"
, XMLForest ( 'HVZ' AS "ber:codeRelatierol"
, xoa.geslacht_hoofdverzekerde AS "ber:geslacht"
, xoa.geboortedatum_hoofdverzekerde AS "ber:datumGeboorte"
, XMLElement( "ber:verzekerde"
, XMLForest ( 'MVZ' AS "ber:codeRelatierol"
, xoa.geslacht_medeverzekerde AS "ber:geslacht"
, xoa.geboortedatum_medeverzekerde AS "ber:datumGeboorte"
-- Some more elements.
) AS bericht
FROM DST_UP1_XML_OUTDATA xoa
The problem is that the XMLForest always creates an <ber:verzekerde> element for medeverzekerde. I tried to create an inline view with just the "vezekerde"attributes and conditionally joining this inline view with the dst_up1_xml_outdata table. That didn't solve my problem. Because in case of a medeverzekerde available it returned two XML documenst: one that included the hoofdverzekerde and one that included the medeverzekerde. And obviously that's not what I want.
I imagine I have to juggle with some of these SQL / XML functions although I cannot put the finger on the exact differences between some of these (XMLElement, XMLForest, XMLAgg, XMLSequence). The examples shown in de XML DB Developer's Guide don't seem to adress my problem.
Help !

Hi, are you talking about this part that you don't want to be there? I am not so clear about your requirements.
XMLElement( "ber:verzekerde"
, XMLForest ( 'MVZ' AS "ber:codeRelatierol"
, xoa.geslacht_medeverzekerde AS "ber:geslacht"
, xoa.geboortedatum_medeverzekerde AS "ber:datumGeboorte"
If you want to control certain subelements so they don't appear, do not use xmlforest. Use xmlelement instead so it is easier to control it using case when. Mark (of Oracle, he should be here soon since OOW is over) showed me this technique and it helps tremendously, because oftentimes XDB will return an empty tag even though your consumers don't like it!
try something like this,
(case when xoa.geboortedatum_medeverzekerde = 'MVZ' then
xmlelement("ber:verzekerde",
xmlelement("What you want", colname),
xmlelement("ber:codeRelatierol", 'MVZ'),
(case when colname is not null or = some other value then
xmlelement("Rest", colname))
end)
end),
You may have to twig some details there. But the key is to use the case when construct to get rid of unwanted elements or empty elements. So you should only have the elements if you have a value of 'MVZ'. Hope this helps.

PL/SQL + XML with Excel report format?

Dear all,
I am a new beginner in XML Publisher. For the EBS11i, I can use PL/SQL with http scripts to generate excel report format.
The following code will include in store procedure:
>
begin
owa_util.mime_header(ccontent_type => 'application/vnd.ms-excel');
     htp.htmlopen;
     htp.headopen;
     htp.print( '<STYLE>' );
htp.print( '' );
     htp.print( '</STYLE>' );
     htp.headclose;
     htp.bodyopen;
     htp.para;
     htp.strong( '<U>' || 'Sample Report Name'|| '</U>');
     htp.para;
htp.tablerowopen;
     htp.tabledata('<DIV align="left">' || rec_main2.vendor_name || '</DIV>',cattributes => ' class="xl24" width="190"');
htp.tablerowclose
>
How can I do that in R12?
Please advice.

We currently do not support SQL aliasing of directories. This
is causing your errors.
