Oracle9i XMLType and namespace declaration

Hi Folks,
I am using the new XMLType for storing XML data and when I want to insert a XML document that contains a namespace declaration
using sys.XMLType.createXML('<lom xmlns="http://www.imsglobal.org/xsd/imsmd_rootv1p2p1"...>...</lom>') function, nothing is inserted into the field and no error message is shown. If I remove the namespace declaration like: sys.XMLType.createXML('<lom>...</lom>') then it works.
I am wondering if there is a problem with the XML Parser or I should do something that I don't. I have read most of the online documents in this regard but couldn't find any answer.
Your help is really appreciated.

I ran into the same (almost) problem a few weeks ago and posted a question to this forum - no response... sigh. Seems like a pretty obvious bug.

Add a root node and namespace declaration

According to the requirement,I have a large appended .txt file.
This .txt file is created by appending various xml files (without the namespace and root node).
I need to add a root node and namespace declaration to the large appended .txt file so that it can be read as .xml.
Please provide the pointers for the same.
Thanks & Regards,
Rashi

My appended file looks like following.
<input>
   <Store>
      <StoreHeader>

            <ItemPrice>56</ItemPrice>
         </Transaction>
      </Transactions>
   </Store>
</input>
Now according to the requirement, I need to add namespace and root node and make it like follows:
<ns0:output xmlns:ns0="http://xxx">

Problems with XMLType and namespace

Dear subscribers:
I have been using XMLType successfully with simple XMLs - without namespaces. Now I must handle messages with "xmlns" and it seems XMLType is failing.
I tested the following XML, extracted from w3c.org examples:
<?xml version="1.0"?>
<bk:book xmlns:bk=''urn:loc.gov:books''
xmlns:isbn=''urn:ISBN:0-395-36341-6''>
<bk:title>Cheaper by the Dozen</bk:title>
<isbn:number>1568491379</isbn:number>
</bk:book>
The result of xmlt.getRootElement() is book.
However, the use of xmlt.extract( 'book' ) returns an empty object:
xmlt1 := xmlt.extract( 'book' );
dbms_output.put_line( 'StringVal: ' || xmlt1.getStringVal() );
ORA-30625: method dispatch on NULL SELF argument is disallowed
The following usages also raise errors:
xmlt1 := xmlt.extract( 'bk:book' );
ORA-31011: XML parsing failed ORA-19202: Error occurred in XML processing LPX-00601: Invalid token in: 'bk:book' ORA-06512: at "SYS.XMLTYPE", line 111
xmlt1 := xmlt.extract( 'bk::book' );
ORA-31011: XML parsing failed ORA-19202: Error occurred in XML processing LPX-00601: Invalid token in: 'bk::book' ORA-06512: at "SYS.XMLTYPE", line 111
xmlt1 := xmlt.extract( 'book', 'bk' );
ORA-31013: Invalid XPATH expression ORA-06512: at "SYS.XMLTYPE", line 119
I am using Oracle version 10.2.0.1.0. Had someone also faced this problem?
The code I used to test is at the end of this message.
Thanks in advance

If you put your XML into a namespace then you also need to extract from that namespace.... e.g.
No namespace...
SQL> select t.xml.extract('myroot')
2 from (select XMLTYPE('<myroot><mychild>test</mychild></myroot>') as xml from dual) t
3 ;
T.XML.EXTRACT('MYROOT')
<myroot>
<mychild>test</mychild>
</myroot>Put XML in namespace and now the extract returns nothing...

2* from (select XMLTYPE('<myroot xmlns="fred"><mychild>test</mychild></myroot>') as xml from dual) t

--------------------------------------------------------------------------------------------------------Extract, specifying the namespace to extract from and now returns the result...

Namespace declaration and W3C standart

Hello,
W3C has following specs for Namespace declaration in XQuery:
http://www.w3.org/TR/xquery/#id-namespace-decls
"[117] NamespaceDecl ::= "declare" "namespace" NCName "=" StringLiteral
A namespace declaration declares a namespace prefix and associates it with a namespace
URI, adding the (prefix, URI) pair to the set of in-scope namespaces. The string
literal used in a namespace declaration must be a valid URI, and may not be a
zero-length string.[err:XQ0046] The namespace declaration is in scope throughout
the query in which it is declared, unless it is overridden by a namespace declaration
attribute in an element constructor.
The following query illustrates a namespace declaration:
declare namespace foo = "http://example.org";
<foo:bar> Lentils </foo:bar> "
BNF production grammar requires "declare" token to be placed before namespace,
while
Liquid Data reports parsing error if the word is there.
How close Liquid Data XQuery grammar to the W3C standart?
Also, does "of type" exist in XQuery ?
Sincerely,
Benjamin.

Thank you for quick answer.
Sorry, my fault - didn't notice that fact.
Benjamin.

JSP documents and namespaces

I have an issue involving JSP documents (i.e. JSP pages that are
          well-formed XML documents). I am using namespaces on children elements
          of the <jsp:root> element, because my JSP page generates XML with
          namespaces. The simple fragment below illustrates this:
          <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
          version="1.2">
          <d:document xmlns:d="http://example.org/xml/document">
          <d:head>
          <d:title>Example</d:title>
          </d:head>
          <d:body>
          Some Text.
          </d:body>
          </d:document>
          </jsp:root>
          This example works with Tomcat 4 and Tomcat 5, but fails with WL
          8.1. I get an error like this:
          /example/my.jsp(20): no corresponding open tag for tag extension
          close: //[ ; Line: 20]
          probably occurred due to an error in /example/my.jsp line 20:
          </d:document>
          This seems to be a bug in the WebLogic JSP implementation. It should
          be possible to generate XML documents containing namespaces. The JSP
          1.2 spec is actually silent on this, but it says (JSP.5.2.2):
          "the root is where namespace attributes of taglibs will be inserted.
          All tag libraries used within the JSP document are represented in the
          root element through additional xmlns attributes."
          This to me implies that namespace declarations occurring elsewhere in
          the document are not interpreted as tag libs and therefore should be
          handled like regular tags.
          Any help is appreciated.

          As far as i can remember, this doesn't restrict the namespaces in themselves
          i.e not attached to any taglibs. Given a namespace which is not resolved as
          a taglib, it will be considered a standard namespace no? .. Am i missing
          something. Also which section and which PFD version of the spec are you
          looking at? It would be great if you can give a little more detail about the
          issue so it can be fixed in the spec if possible..
          I would also be interested in knowing how you are using the Jsp documents
          (in xml format) in general. (since I'm trying to get an insight into the
          various ways in which jsp Docs are being used by customers)

Avoid repeating namespace declaration in xml output

Hi all,
I'm trying an IDoc -> XML File (specifically UBL-format) scenario, and it is working fine. But the resulting XML contains repeating namespace declarations for each element, instead of a "common" declaration at the root element.
How can I avoid this, so the message contains the namespace declarations in root node, and only uses the namespace prefix for each element?
The target format, external definition, is an XSD with several import statements, and all external references have been set up, meaning all referenced XSD's are imported too, and have the "Source"-field set according to the import statement.
Sample result file (top of file only):
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Invoice xmlns:ns0="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2">
<ns2:UBLVersionID xmlns:ns2="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">2.0</ns2:UBLVersionID>

Thanks for all help.

Hi Mon,
You can use below xslt 1.0 mappings.
The first one will copy all namespaces (declared) to a newly created root element.
The seconde one will delete the 'old' root element.
=> The result will look like an xml where the namespacesare moved to the root element.
First xslt:
<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:template match="/">
<Invoice xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ns1="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:ns3="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:ns4="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2">
<xsl:copy-of select="." />
</Invoice>
</xsl:template>
</xsl:stylesheet>
Second xslt:
<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Invoice" >
<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
Kind regards,

RFC Call: Missing namespace declaration

Dear experts,
I have a file to RFC scenario. I imported the RFC and create files exactly according to the RFC structure, so I don't use a mapping. When I create a file, it provides the following error in the adapter log:
<i>Exception caught by adapter framework: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: could not get functionname from XML requst: com.sap.aii.af.rfc.RfcAdapterException: failed to read funtionname from XML document: missing namespace declaration(2)</i>
What do I need to do to fix this.
Thanks in advance!

This is the whole message:
I created my own interface and mapped it to the RFC:
This is the message. Now it successfully pass XI and the adapter sais it is delivered.
BUT nothing is seen in the target system... how is that possible???

How to remove SOAP namespaces declarations in body content?

Hi!
I'm calling a WS with WS-Security without problems but when I extract the content the SOAP message's Body(the "business" part), the namespace declarations of the SOAP part (envelope, security, etc.) are present in the root element. However, any of this namespaces is referenced in the message that I extract.
I'm extracting the message inside the body like this
XmlObject[] aXml = xml.selectPath(##THE QUERY##);
return XmlObject.Factory.parse(aXml[0].xmlText(_opts));
Is there a way of getting rid of these declarations?
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
I've tried changing the XmlOptions (setSaveAggresiveNamespaces, setLoadSubstituteNamespaces, etc.) without success.
Thanks in advance!

just use $body/* and you will have what u wanted.

E4X and Namespaces - How best to handle?

Hi,
I need to use E4X to create a list of nodes of a particular type from an xml document returned form a Web Service. The document uses multiple namespaces, so I can't access its content, event nodes which aren't prefixed with a namespace.
I can get round this problem by using:
namespace all = "http://www.w3.org/2005/Atom"
use namespace all;
in the class which parses out the nodes, however, I want to wrap the nodes in an XMLListCollection and set them as a list's dataProvider, and becuase the node's themselves have namespaces declared, it seems that the list can't access the nodes (which all have a label property) and displays the whole node instead.
What is the correct way to handle this situation?
Thanks.

Hi Alex,
Thanks for the reply. Overlooked that completely.

Retrieve namespace declarations from unmarshalled object

Hi,
     I hope this is a beginner's question:
Still working on a web service, that uses an EJB for implementation. I'm using types/classes that were derived automatically from a WSDL (top-down/outside-in/what have you), or rather the corresponding schemata. I'm trying to retrieve namespace declarations from the unmarshalled object/element, but they are not contained in the "otherAttributes" [Map<QName, String>] member field of the respective object. However, I can retrieve any other attribute, qualified and non qualified, as long as the namespace isn't that of xmlns (http://www.w3.org/2000/xmlns/). For example:
Client:
            MyElement my_element = new MyElement();
            Map<QName, String> atts = my_element.getOtherAttributes();
            QName ns_att = new QName("http://www.w3.org/2000/xmlns/", "a");
            atts.put(ns_att, "http://www.example.com/");
            QName test_att = new QName("test-att");
            atts.put(test_att, "http://www.example2.com");
Service:
            MyElement my_element = parent.getMyElement(); // ...
            Map<QName, String> atts = my_element.getOtherAttributes();
            for (QName qn : atts.keySet()) {
                System.out.println("qn: ["+qn+"] value["+atts.get(qn)+"]");
This would print:
qn: [test-att] value[http://www.example2.com]
What am I missing? How do I get the namespace declaration? Thanks for your help in advance.
Cheers,
Felix

I'll try to explain in a better way ...
I have a server with 2 different client and each client communicate to the server with a different interface.
My needs are to recognize from the server, the type of the client that are operating, and to do this I was thinking to recognize the interface used from the client to interact with the server
An other option is that, from the client, after retrieving the server and it's cast, a can call a method to pass to the server object, the type of the interface actually used.
But I think this makes a bit of nonsense because When I receive the marshalled object in my opinion doesn't make sense that i have to say the object it's type (the interface used).
the object is already alive and I think it has to know the interface used to refer it even if is on another VM
The cast operation doesn't store nothing into the current object instance?
local code example (I don't know if with JRMI the situation is different because the different JVM)
Map foo = new HashTable();
I need a method like
foo.curretUsedInterface() ... that return "Map"
instead of
foo.getClass().getName() that return "HashMap"
It's possible to obtain this information or I have to try another idea to make the server distinguish the client type?
thank you very much for your comprehension

Unnecessary Namespace declarations

Hi,
When mapping (graphic) to an externally defined XML schema where some elements belong to different namespaces I get namespace declarations on each element in the resulting XML instance even though they refer to the same ns name. The problem is that the XML document, even though valid, is very verbose. Is there a way to get all ns declarations in the root element instead without using XSLT?
Example output
<?xml version="1.0" encoding="utf-8" ?>
<ns1:RootElement xmlns:ns1="http://foo.com">
<ns2:Element1 xmlns:ns2="http://junk.com" />
<ns2:Element2 xmlns:ns2="http://junk.com" />
<ns2:Element3 xmlns:ns2="http://junk.com" />
</ns1:RootElement>
I would like to get something like this instead:
<?xml version="1.0" encoding="utf-8" ?>
<ns1:RootElement xmlns:ns1="http://foo.com" xmlns:ns2="http://junk.com">
<ns2:Element1 />
<ns2:Element2 />
<ns2:Element3 />
</ns1:RootElement>
Kind regards Johan

Hi,
I was probably not clear enough in my question.
My Scenario is CRM -> Xi -> External system.
The inbound interface to the external system is a predefined XML Schema where not all components/elements belong to the same namespace.
When executing a mapping, created with the graphical mapping tool in Xi, the resulting XML document/Instance is valid but very verbose since XI put namespace declarations in every element over and over again instead of just putting them once in the root element.
I don't think this has anything to do with the XSD, but rather with the mapping program.
The result is that the receiving system takes a performance hit. I would like to find a way to force XI to just declare the same ns once in the root element instead of over and over again?
kind regards Johan

Duplicate namespace declarations when writing a file with JCA file adapter

I am using JCA File adapter to write a an XML file. The composite contains a mediator which received and transforms an XML to desired format and then calls a JCA file adapter to write the file.
The problem that I am having is that the written file has declaration of namespaces repeated with repeating elements instead of a single declaration at root. For ex.
instead of
<ns0:Root xmlns:ns0="namespace0" xmlns:ns1="namespace1" xmlns:ns2="namespace2">
<ns0:RepeatingChild>
<ns1:Element1>value1</ns1:Element1>
<ns2:Element2>value2</ns2:Element2>
</ns0:RepeatingChild>
<ns0:RepeatingChild>
<ns1:Element1>value3</ns1:Element1>
<ns2:Element2>value4</ns2:Element2>
</ns0:RepeatingChild>
</ns0:Root>What I see in the file is:
<ns0:Root xmlns:ns0="namespace0" xmlns:ns1="namespace1" xmlns:ns2="namespace2">
<ns0:RepeatingChild>
<ns1:Element1 xmlns:ns1="namespace1" xmlns:"namespace1">value1</ns1:Element1>
<ns2:Element2 xmlns:ns2="namespace2" xmlns:"namespace2">>value2</ns2:Element2>
</ns0:RepeatingChild>
<ns0:RepeatingChild>
<ns1:Element1 xmlns:ns1="namespace1" xmlns:"namespace1">>value3</ns1:Element1>
<ns2:Element2 xmlns:ns2="namespace2" xmlns:"namespace2">>value4</ns2:Element2>
</ns0:RepeatingChild>
</ns0:Root>So basically all the elements which are in different namespace than root element have a namespace declaration repeated even though the namespace identifier is declared at the root elment level.
Although, the XML is still valid, but this is unnecessarily increasing the filesizes 3-4 times. Is there a way I can write the XML file without duplicate declarations of namespaces?
I am using SOA Suite 11.1.1.4
The file adapter has the schema set as above XML.
I tried the transformation in mediator using XSL and also tried using assign [source(input to mediator) and target(output of mediator, input of file adapter) XMLs are exactly same].
but no success.

I used automapper of JDeveloper to generate the schema. The source and target schema are exactly same.
I was trying to figure it out and I observed that if the namespaces in question are listed in exclude-result-prefixes list in xsl, then while testing the XSL in jDeveloper duplicate namespaces occur in the target and if I remove the namespace identifiers from the exclude-result-prefixes list then in jDeveloper testing the target correctly has only a single namespace declaration at the root node.
But, when I deployed the same to server and tested there, again the same problem.

CFFEED & Namespace Declaration

I would appreciate some help with generating rss feed for Google Merchant. I am trying to use cffeed to generate the xml file which I am good with. The issue is formatting it to google's specifications and their namespace declaration (<g:price></g:rpice>) how to set a xml structure to include g: in front of the names?
Here is a sample of googe xml structure:
<?xml version="1.0"?>
<rss version="2.0"
xmlns:g="http://base.google.com/ns/1.0">
<channel>
<title>The name of your data feed</title>
<link>http://www.example.com</link>
<description>A description of your content</description>
<item>
<title>Red wool sweater</title>
<link> http://www.example.com/item1-info-page.html</link>
<description>Comfortable and soft, this sweater will keep you warm on those cold winter nights.</description>
<g:image_link>http://www.example.com/image1.jpg</g:image_link>
<g:price>25</g:price>
<g:condition>new</g:condition>
<g:id>1a</g:id></item>
</channel>
</rss>

I had a google around, and as far as I can tell it cannot be done with <cffeed> (*). Just use <cfxml> instead, I reckon.
And maybe raise an issue with Adobe: http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html. If you do so, and post the bug ref back here, I'll vote for it too :-)

Inclusion of unused namespace declarations in marshalled XML

Hello.
I have noticed that by default any XML marshaled from an object contains namespace declarations related to every package specified when instantiating the JAXBContext even though they are not used in the instance being marshalled.
Is there any way to avoid this during the marshalling as opposed to via some sort of post processing (e.g. XSLT transform).
Example source below:
package test;
import javax.xml.bind.*;
import java.io.*;
import test.sample1.*;
import test.sample2.*;
public class Converter {
     public static void main(String[] args) {
          try {
               String sample1 = "<Message1 xmlns=\"http://www.example.org/sample1\">" +
                                         "<tns:Field xmlns:tns=\"http://www.someother.org\">value</tns:Field>" +
                                    "</Message1>";
               String sample2 = "<Message2 xmlns=\"http://www.example.org/sample2\">" +
                                        "<Field1>value1</Field1>" +
                                        "<Field2>value2</Field2>" +
                                    "</Message2>";
               JAXBContext ctx = JAXBContext.newInstance("test.sample1:test.sample2");
               Unmarshaller um = ctx.createUnmarshaller();
               Marshaller m = ctx.createMarshaller();
               StringWriter sw1 = new StringWriter();
               Message1 msg = (Message1)um.unmarshal(new StringReader(sample1));
               m.marshal(msg, sw1);
               System.out.println("Marshalled sample1: \n"+sw1.toString());
               StringWriter sw2 = new StringWriter();
               Message2 msg2 = (Message2)um.unmarshal(new StringReader(sample2));
               m.marshal(msg2, sw2);
               System.out.println("Marshalled sample2: \n"+sw2.toString());
          } catch (JAXBException e) {
               e.printStackTrace();
}Produces output:-
Marshalled sample1:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Message1 xmlns:ns2="http://www.example.org/sample2" xmlns="http://www.example.org/sample1"><tns:Field xmlns:tns="http://www.someother.org">value</tns:Field></Message1>
Marshalled sample2:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><ns2:Message2 xmlns:ns2="http://www.example.org/sample2" xmlns="http://www.example.org/sample1"><ns2:Field1>value1</ns2:Field1><ns2:Field2>value2</ns2:Field2></ns2:Message2>

Thanks for the quick response. I really appreciate it.
Yes, as you say, there is no real problem as such but part of my app lets the user see the RAW message XMLs and this could confuse them and would be tidier to remove but I can also see why it is easier from the Marshaller perspective not to have to back track to remove unused declarations.
Also, I'm a little concerned about the increased size of the XML produced. One of my webservices does handle quite a few different types and our Oracle namespace URLs are all pretty long!
Like I say, I can see a way to get rid of them after the fact but wondered if there was a more elegant/performant way.

Add dynamic namespace declaration into xml root element

Hello all,
i've have two scenarios (mail to mail and file to file) with the same issue : no namespace in my XML file and i have to create one 'dynamically' from XML values.
Example :
<root>
<name>test</name>
<email>test</email>
<schema>schemaID</schema>
</root>
Now I want to add infos into the root element for namespace declaration and so on, without expansion of the xsd. I've must use the value from the field schemaID.
Example:
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns: namespace="http://test.de/schemaID">
<name>test</name>
<email>test</email>
</root>
I've already done it before through XSLT but it wasn't dynamic !! I don't know how to do it in XSL and i am not a java expert.
Someone got an idea ?
Thanks,
Jean-Philippe.

Hi,
If you want to add name space at mapping level two options
1)Using XSLT Mapping ,its very easy,google it to get sample XSLT code ,it will solve your problem.
2)Using java mapping,in java mapping use regular expression code ,using regex(Regulkar expresion)we can add any content in message at any level.

Raj
