Format using default namespace prefix.

Is there any way to format XML using default namespace prefix in an expression?
My expression is as follows:
oraext:get-content-as-string(bpws:getVariableData('JmsMdx_InputVariable','body'))

This seems wrong to me. I've filed Bug 2400119 to get this looked into by development.
I'd expect any document with an appropriate qualified name to be found by your XPath expression, irrespective of whether syntactically one of the documents happened to use the default namespace syntax.

How to suppress n0: default Namespace prefix in Transformations

Hi,
I use Simple Transformations for serialization of deep structured data.
In the XML File the whole tree needs to use a special namespace. Therefore i use the attribute xmlns="ABC.de" without a namespace prefix in my root element. During serialization SAP generates a default namespace prefix like 'n0:'.
Is it possible to suppress the generated namespace prefix?
Thank you very much for reply
René

Maybe somebody is interested.
It seems to be a problem on old 640. On a NW 702 the result is as expected. NW 700 was not tested.
Workaround for the 640 is to use as result a STRING field not an XSTRING.
Greetings René

XML DB: using default namespace gives different result

In Oracle9i R2 I created an XMLTYPE table based on a XML schema. The schema uses a namespace. When I insert an instance document that has a namespace prefix for every element querying works fine. When I insert an instance document that has the namespace defined as the default namespace, the query returns an empty row for that document. It seems to me that before storing the document the namespaces must be expanded and hence there should be no difference between the two documents and the query should return a value for both rows. Any thoughts? Thanks in advance! Below is the script and the results of the queries.

How are you using the Namespace Prefix?

As the subject says...
The top-level namespace prefix looks very useful for segregating projects into their own namespaces...is this what this is for, or does SAP have another recommended use for this prefix?
The vendor name already makes the namespace unique to a corporate entity (if you use the domain name), so anything after that is really only of importance to the internal development environment...

Even if your development isn't that big, using the 'name space prefix' would allow you to further segregate your codebase.
This also becomes important when your domain name is rather long - 15 characters. Take away four or so more for the namespace prefix, and you're left with 20 characters for the DC name. Add in a few separators, and you're down to 12-15 characters.
Obviously, readability can suffer when you start to abbreviate too much, so I'm looking for best practices when it comes to the namespace prefix.
Thanks for your comment.

Using default namespace with XMLNode.valueOf()

XMLNode.valueOf(String, NSResolver) takes in a namespace resolver. Is it possible to specify a default namespace with the namespace resolver so that if the XSL Pattern is not qualified, e.g., "/myElt/bar", default namespace will be used?
Thanks.

Things that are wrong with the mapped XML: 
- the namespace "http://www.MyTest.com/My_Namespace/Part3" was prefixed with MyNS3 but XI reassigned it to ns0
 - original prefixes are not used in the element tags 
 
Appreciate if anyone can help. 
Thanks.

Thank you for all your valuable suggestions. Does any know why XI/PI does not acknowledge/use the namespace prefix that is defined in the XML? Is there no other way around this short-coming apart from using XSLT mapping?
 
I did try using the anonymizer (as suggested by Manjusha). With the anonymizer I am able to change the namespace prefix in the element tags to the way I want it. However the namespace definition is still showing in the element tag.
 
 <MyNS2:SubStruc_1 xmlns:MyNS2="http://www.MyTest.com/My_Namespace/Part2"> 
 <MyNS2:Fld_1_1_A>Value001</MyNS2:Fld_1_1_A> 
 <MyNS2:Fld_1_1_B>Value002</MyNS2:Fld_1_1_B> 
 </MyNS2:SubStruc_1> 
 
This is almost perfect only if I am able to remove the definition xmlns:MyNS2="http://www.MyTest.com/My_Namespace/Part2" from the element tag. Suggestion any one?
Thanks All.

JDeveloper 10.1.3 - Disabling ns0: namespace prefix in soap body children ?

I am attempting to use a PeopleSoft web service. However, the PeopleSoft web service does not recognize operations which have a namespace prefix. Using visual studio, namespace prefixes are not used in the child elements of the soap body element. I am able to call the service using visual studio.
JDeveloper 10.1.3 uses a namespace prefix for children of the body element which is recommended by the soap spec. However, I need to disable that behavior so that I can actually get the program working with PeopleSoft.
Can anyone tell me if there is an easy way to disable the ns0: prefix that is used by the generated web service proxy stub? I have traced through the generated proxy code but I do not see any properties that can be modified. The only thing I can think of is to modify the generated code but I do not want to go that route.
Thanks,
Rich

Delete the NS0: related text, in JDev, from your WSDL and it should work. I had the same problem with .NET not liking it also.
Keep in mind you'll have to tweak the WSDL again if you regenerate it.
You sure you're using 10.1.3? I upgraded and it shows the NS0: as a problem in existing projects. I'm working on the latest, production download so maybe it's been corrected.

Output XML with a default namespace using XQuery

I'm having a problem with namespaces in an XQuery within ALSB.
We receive XML from a file which doesn't have any namespace and have to transform it into a different structure, giving it a default namespace such as below:
Input XML
<inputRoot>
 <inputAccountName>Joe Bloggs</inputAccountName>
 <inputAccountNumber>10938393</inputAccountNumber>
</inputRoot>
Desired output XML
<outputRoot xmlns="http://www.example.org/outputSchema">
 <outputAccounts>
 <outputAccountName>Joe Bloggs</outputAccountName>
 <outputAccountNumber>10938393</outputAccountNumber>
 </outputAccounts>
</outputRoot>
When I attempt to do this using XQuery mapper tool, I end up with a namespace prefix on the outputRoot. The XQuery and result follows:
XQuery
declare namespace xf = "http://tempuri.org/XQueryProject/scratchTransformations/test/";
declare namespace ns0 = "http://www.example.org/outputSchema";
declare function xf:test($inputRoot1 as element(inputRoot))
as element(ns0:outputRoot) {
<ns0:outputRoot>
<outputAccounts>
<outputAccountName>{ data($inputRoot1/inputAccountName) }</outputAccountName>
<outputAccountNumber>{ data($inputRoot1/inputAccountNumber) }</outputAccountNumber>
</outputAccounts>
</ns0:outputRoot>
declare variable $inputRoot1 as element(inputRoot) external;
xf:test($inputRoot1)
Result
<ns0:outputRoot xmlns:ns0="http://www.example.org/outputSchema">
 <outputAccounts>
 <outputAccountName>inputAccountName_1</outputAccountName>
 <outputAccountNumber>inputAccountNumber_1</outputAccountNumber>
 </outputAccounts>
</ns0:outputRoot>
How can I write the XQuery in such a way thay the namespace prefix isn't output? I've tried many different methods with no success. I can't declare a default element namespace because my input element doesn't have a namespace
Thanks in advance

I spoke too soon, it didn't work quite as perfectly as I'd thought :-) It turns out our client can't handle the xml with the namespace prefix but we've worked out the solution to return XML in the format we originally needed.
Example below:
XQuery
declare namespace xf = "http://tempuri.org/XQueryProject/scratchTransformations/test/";
declare default element namespace "http://www.example.org/outputSchema";
declare namespace ns1 = ""
declare function xf:test($inputRoot1 as element(ns1:inputRoot))
as element(outputRoot) {
<outputRoot>
<outputAccounts>
<outputAccountName>{ data($inputRoot1/inputAccountName) }</outputAccountName>
<outputAccountNumber>{ data($inputRoot1/inputAccountNumber) }</outputAccountNumber>
</outputAccounts>
</outputRoot>
declare variable $inputRoot1 as element(inputRoot) external;
xf:test($inputRoot1)

XQuery mixed prefixed / default namespaces in input documents

Hi there,
I am developing an Atom Publishing Protocol server. The feeds produced by the server, which are regular atom documents being generated with XQuery, need to be formatted such that they have no namespace prefixes, only xmlns="..." attributes. However, my input documents (atom entry documents stored in dbxml) sometimes have the atom: namespace prefix.
How can I get XQuery to 'notice' that the namespace is the same as the default element namespace and remove the prefixes from the output?
Example input document in database (generated by Windows Live Writer):
<?xml version="1.0" encoding="utf-8"?>
<atom:entry xmlns:atom="http://www.w3.org/2005/Atom">
<atom:id>urn:uuid:a8cc06e6-3d63-4411-a984-019dc3bf6d75</atom:id>
<atom:title>With NS</atom:title>
<atom:content type="html">aera raw
awre awre aw
 awreawer
awer 
 awer </atom:content>
</atom:entry>
Some XQuery that reproduces the problem:
declare default element namespace "http://www.w3.org/2005/Atom";
declare namespace app = "http://www.w3.org/2007/app";
let $entries := collection('dbxml:entries')/entry
return
<feed xmlns="http://www.w3.org/2005/Atom">
<id>http://some.server/</id>
<title type="text">Example of problem</title>
<author><name>Andrew Bruce</name></author>
<updated>{current-dateTime()}</updated>
<link href="http://some.place/" rel="self"/>
{$entries}
</feed>
This outputs (formatted to aid readability):
<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
<id>http://some.server/</id>
<title type="text">Example of problem</title>
<author><name>Andrew Bruce</name></author>
<updated>2008-04-05T22:47:23.136Z</updated>
<link href="http://some.place/" rel="self"/>
<atom:entry xmlns:atom="http://www.w3.org/2005/Atom">

<atom:title>With NS</atom:title>
<atom:content type="html">aera raw
awre awre aw
 awreawer
awer 
 awer </atom:content>
</atom:entry>
</feed>
Any help would be greatly appreciated.

Hi Andrew,
DB XML will try to preserve the namespace prefix or lack-thereof of the XML it is serializing. In this case the atom entry from the source document uses the prefix, so DB XML uses it. Since the choice of namespace prefix is orthogonal to the meaning of the XML document, DB XML does not provide a way to alter this behaviour.

Namespace prefix: Using Anonymizer

Hi guys,
I'm having some difficulties using XMLAnonymizer for placing some namespace prefix's in my message.
After sending the message, I can check on RWB that the module Anonymizer is loaded, but results in the following:
2007-06-21 16:55:45 Success MP: processing local module localejbs/AF_Modules/XMLAnonymizerBean
2007-06-21 16:55:45 Warning Anonimizer: message is empty or has no payload
2007-06-21 16:55:45 Success MP: leaving
Well, why do I have message empty? to what message is he referring to?
Why do I need Anonymizer? Well, the thing is, some namespace prefixes are not being place on the sent message. Without this prefixes the actual mapping fails and no fields are mapped....
Can you give me a hand?

Hi Stefan,
Thanks for your reply! It works, well, the anonymizer gets the message, but now I've another question....

2007-06-22 11:04:42 Success Message successfully put into the queue.
I've checked my message but a strange thing happened, maybe I've misunderstood the anonymizer function....
The original message was:
So the namespaces introduced were deleted. But What I thought it was going to happen was that the Anonymizer would introduce the prefix ns0 and ns1 on the tags that had the namespace declaration.... Is this possible with the anonymizer?
Problem solved.... it was a wrong namespace :S
Thanks for the help Anonymizer does wonders and saves a hell lot of time

I'm just new to XMLP and am receiving the same error.. My error is occuring when trying to use sub-templates in my master template.
I believe I have the syntax correct:
To import template file:
<?import:file:h:///CN_LTR_TEMPLATES.rtf?>
to call the sub-template:
<?call-template: signature:?>
Its the call-template to signature thats generating my error message.. My only thought is that its not calling my import properly..
Anyway.. Hope this might help you a bit.. you never mentioned anything about using a sub-templates. Perhaps since you formated your computer, your template may be in a different location or gone all together (that is if you are using sub-templates).
If i figure anything out in the mean time, i'll let you know..

"...Prefix when a default namespace..." error inside javascript

I get this exception:
The function $ must be used with a prefix when a default namespace is not specified
in this piece of jsp code
<html:checkbox property="copyAddress" value="true"
onclick="if (this.checked) { $('postal').hide()} else { $('postal').show(); }"/>Also, I get this error locally but not in the server. I use tomcat 5.5, jsp-api 2.0 and servlet-api 2.4.
What's wrong? Please help me
Edited by: poroto20 on Jan 13, 2010 6:56 AM

I would move this method over to its own function and pass the arg in full.
Also if this is JQuery then it sould read, if this is Struts then there are better ways of doing this.
if (this.checked) { $('#postal').hide()} else { $('#postal').show(); }"
{code}
When you create the method wrap it up in a try catch (Javascript try catch) and see what outputs. You can also use Firefox/Firebug to get better debugging information regarding JS errors.
Also you should read as follows, otherwise you will get a JS error
{code}
if (this.checked) $('postal').hide(); else $('postal').show();
{code}
Note the ";" after the hide();

Unknown namespace prefix Error - when using custom Aliases with RDF aliases

I am getting unknown namespace prefix error when I use custome SEM_ALIAS with rdf SEM_ALIAS. It seems once you specify custom SEM_ALIAS, the default rdf alias is not recognized. Following are the details of queries
I have a sem_Model "test" which has "event" as a class and "Merger" as a sub-class of event, with "acquiringorg" as a property having the domain "org". "Org" is also defined as a class with the literal attribute "hasname". I have added one instance of "merger" class with appropriate values for "acquiringorg" property. There is one instance or "Org" as well for reference in the instance above.
the following query(return all objects having property "acquiringorg" and its .e. "hasName" attribute for the object) runs fine and returns appropriate resultset
select x event,z acquiringorg ,l acquireeorg from table(SEM_MATCH(
'(?x Evnt:AcquiringOrg ?y)(?k orgn:hasName ?l)',
SEM_MODELS('test'),
null,
SEM_ALIASES(SEM_ALIAS('Evnt','http://www.abc.com/Event/Merger/'),
SEM_ALIAS('orgn','http://www.abc.com/Org/')),
null));
However when I want to add another criteria i.e. show me events of type merger(?x rdf:type :Merger) , the query fails with the "unknown namespace prefix error" as above
select x event,z acquiringorg ,l acquireeorg from table(SEM_MATCH(
'(?x rdf:type :Merger)(?x Evnt:AcquiringOrg ?y)(?k orgn:hasName ?l)',
SEM_MODELS('test'),
null,
SEM_ALIASES(SEM_ALIAS('Evnt','http://www.abc.com/Event/Merger/'),
SEM_ALIAS('orgn','http://www.abc.com/Org/')),
null));
specifying "rdf" ALIAS explicitly also does not work
select x event,z acquiringorg ,l acquireeorg from table(SEM_MATCH(
'(?x rdf:type :Merger)(?x Evnt:AcquiringOrg ?y)(?k orgn:hasName ?l)',
SEM_MODELS('test'),
null,
SEM_ALIASES(_SEM_ALIAS('rdf', 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'),_
SEM_ALIAS('Evnt','http://www.abc.com/Event/Merger/'),
SEM_ALIAS('orgn','http://www.abc.com/Org/')),
null));
I am unable to figure out why default namespace i.e. rdf is returning this error
Stuck at this point badly!!Any pointers would be useful!!

Full error details are as below
ORA-29532: Java call terminated by uncaught Java exception: oracle.spatial.rdf.server.ParseException: Unknown namespace prefix ''

JAXB: using anonymous namespace (no prefix)

I am using a namespace for my JAXB serialized object, so that the first part looks like that:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:DataRecords xmlns:ns2="http://test.org/DataRecord/" StartProcessingTime="2010-05-20T12:34:37.123Z" ChargingDataVersion="1.0">
<Item>
....As you can see JAXB uses the default Prefix "ns2" for assigning the DataRecords node to the namespace. Due to a special request I need
to use an anonymous namespace with no prefix, something like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<DataRecords xmlns="http://test.org/DataRecord/" StartProcessingTime="2010-05-20T12:34:37.123Z" ChargingDataVersion="1.0">
<Item>
....If I got the XML specifications right this should do the job as well, as long as only one namespace is used. Using JAXB I only recognized the
possibility to change the prefix via a property of the marshaller and a custom prefix manager. But it seems impossible to abandon the prefix
completely (returning null or an empty string in the custom prefix manager falls back to the default name prefixes)
any idea?

This seems wrong to me. I've filed Bug 2400119 to get this looked into by development.
I'd expect any document with an appropriate qualified name to be found by your XPath expression, irrespective of whether syntactically one of the documents happened to use the default namespace syntax.

Please reply if anyone has solved this problem before.

Hi ,
>>>i removed namespace from source and target Message Type of message mapping but still getting "ns3" prefix. My requirement is to just have this ns3 removed.
Which process you've used for removing namespace...java/xslt mapping. In case of java mapping plese remove ns3 while creating the target element. Please go through the below blog it may help you.
