Namespaces in DTD

I can specify the namespace of the element in DTD
by declaring the xmlns attribute for it with
#REQUIRED value of namespace the element belongs to.
But how can I specify elements with the same name
belonging to different namespaces in one single
DTD not to get error of duplicate definition of element?

I read this documentation to get familiar with XML DTD,
but when I tried to do what I mentioned above, I didn't
find answer for that.

Import cXml dtd

We downloaded cxml 1.2 dtd from cxml.org and tried to import into XI external def. We imported cxml.dtd and received no errors. When accessing from message mapping and Message Type we are unable to import/select cXml dtd structures/messages.
How do we import cXml dtd message into XI?
We have tried to convert to a .xsd file using Xml Spy and are experience namespace errors.

Hi Frank,
concerning namespaces the philosophies of DTD and XSD are not compatible (indeed the philosophy of DTD is not compatible with that of XML namespaces itself). As XI is completely XSD-based it is not able to deal with DTDs containing namespace information, although they are well-formed.
Other tools (like XMLSpy) may try to make a conversion anyway (on a somehow heuristic basis). The result of that maybe imported as External Definition, but sometimes it is necessary to make some adjustments to the XSD.
According other DTDs coming from cxml I cannot tell you, because I do not know. Anyway, the namespace information is an important information which cannot be left out. If the XML structure defined by cxml really uses xml namespaces, then DTDs are not a suitable way to describe this structure (as explained above). XML structures with namespaces should always be described using XSD.

Using Log4j2 in weblogic for logging in OSB

Hi All,
I was trying to use log4j2 logging in OSB. I did below mentioned steps:
Copied external jars "log4j-api-2.0-beta7" and "log4j-core-2.0-beta7" into %Domain_Home%\lib directory.
Placed wllog4j.jar into same location.
Created log4j2.xml and placed it into %Domain_Home% directory.
Modified setDomainEnv.cmd in %Domain_Home%\bin directory to include log4j2.xml location(set LOG4J_CONFIG_FILE=%DOMAIN_HOME%\log4j2.xml) and enable log4j logging by setting java option(-Dwlw.log.Log4jLoggingEnabled=true)
Content of log4j2.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="debug" name="MyApp" packages="">
   <appenders>
      <RollingFile name="RollingFile" fileName="C:/Oracle/MiddlewareNew/user_projects/domains/base_domain/servers/AdminServer/logs/services.log" filePattern="logs/$${date:yyyy-MM}/app-%d{yyyy-MM-dd-HH}-%i.log.gz">
         <PatternLayout>
            <pattern>%d %p %m%n</pattern>
         </PatternLayout>
         <Policies>
            <TimeBasedTriggeringPolicy/>
            <SizeBasedTriggeringPolicy size="10 MB"/>
         </Policies>
         <DefaultRolloverStrategy max="10"/>
      </RollingFile>
      <Async name="Async">

      </Async>
   </appenders>
   <loggers>
      <root level="debug">
         <appender-ref ref="Async"/>
      </root>
   </loggers>
</configuration>
After setting all the above things, when i am starting weblogic server then i am getting parsing exception in console with error like below:
log4j:ERROR Parsing error on line 3 and column 44
log4j:ERROR Document root element "configuration", must match DOCTYPE root "null
log4j:ERROR Parsing error on line 3 and column 44
log4j:ERROR Document is invalid: no grammar found.
log4j:WARN The <configuration> element has been deprecated.
log4j:WARN Use the <log4j:configuration> element instead.
I am not able to figure out what is going wrong here. In my information log4j2 has done away with namespaces, schema/dtd references and looks like still weblogic is using log4j 1.2 reference. I would really appreciate of one can tell me what is going wrong here.
There was reference to log4j-1.2.8 in my setDomainEnv.cmd as
set POST_CLASSPATH=%POST_CLASSPATH%;%ALSB_HOME%\lib\version.jar;%ALSB_HOME%\lib\alsb.jar;%ALSB_HOME%\3rdparty\classes;%ALSB_HOME%\lib\external\log4j_1.2.8.jar;%DOMAIN_HOME%\config\osb
could this be causing issue? If yes then how can we remove old references of log4j 1.2(if i am removing this entry from here then log4j is giving error for classes not found).
Any input will be helpful.

The log4j:ERROR messages are not coming from Log4j 2 and are most likely from Log4j 1.x. Somehow Log4j 1.x must be getting the log4j2 configuration.

Spliting xml document- or sending portion of xml document

Hi,
I have large xml document and has to share between multiple components. But each component requires only portion of xml .How to pass only portion of node value as xml documentto different component.?
say I have the following xml file.
<AccountManager name="AccountManager" type="java" namespace="com.AccountManager">
     <Transformer name="RequestTransformer" type="java" namespace="com.RequestTransformer">
          <Resource name="RequestDTD" type="dtd" namespace="RequestDTD.dtd"/>
          <Resource name="RequestXSLT" type="xslt" namespace="RequestXSLT.xslt"/>
     </Transformer>
</AccountManager>
I want to send Transfomer node to different component. (This should include Resource Name i.e., all child nodes).

Convert the node that is to be sent to a String with either the Transformer API or DOM 3 Load and Save API and send the string.

Accssing xml tags with name space

<XML>
<A> Text line 1 </A>
<A> Text line 2 </A>
<A> Text line 2 </A>
</XML>
I need to know how to Create and access the tag values using name space. could you send me the code please ?
Thanks

Hi:
If you want to use namespace in XML file. You have to define a DTD file or Schema file. Those file you created to validate the XML file. So you can also define a namespace in DTD and Schema or not.
When you define a namespace in DTD or Schema, you can use a prefix in front of tag name.

Namespace addition in a DTD in ESR

Hi,
I have imported an external definition, a DTD, in my ESR. In external definition window in ESR there is a tab WSDL where I cant see namespace for he schema.
Can someone help me with how to get namespace in that WSDL or how to declare and add a namespace in a DTD (doctype) structure?
PFB the my DTD structure where MyMessage is root node in message structure.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE MyMessage SYSTEM "http://host.com/app_docs/dtd/PO/xyz.dtd" [

<!ELEMENT abc (#PCDATA)>

DTD's and namespace

Hi,
According to a number of threads on this forum it is not possible to import and use DTD's with namespaces in it. These posts are rather old. So, is this still the situation?
If yes,
What's the best way to go on with DTD's with namespace?
When I convert the DTD into XSD using Stylus the XSD is not recognized by XI after importing it as a External Definition.
Best regards
Ron

Hi Ron
On service.sap.com , SAP solutions / Netweaver / NW in detail / process integration / XI / Media Library / documentation you find some excel file that indicate the current subset of an open standard ( WDSL / DTD etc..) supported by SAP according to the SP level.
But I think it hasn't changed yet.
When you imported as XSD, did you try to choose 'from all unreferenced global elements '

Dom can't parse dtd reference in xml file

Hi all,
I am trying to parse a xml file (hibernate mapping file *.hbm.xml) using DOM. But itis getting timeout errorwhile parsing due to the external dtd reference in the xml file.

How to use the namespace with a parser?

I want to use the namespace in my project. For this reason, I use a sample
from
http://java.sun.com/xml/jaxp/dist/1.1/docs/tutorial/sax/7b_pe.html
http://java.sun.com/xml/jaxp/dist/1.1/docs/tutorial/dom/5_ns.html
to test my understanding.
The slideshow2.dtd refer to the definition in 'xhtml.dtd'. Because in these
two files, they all use the 'title' as the element names. To solve these
conflicts, The namespace is used to qualified the one in slideshow2.dtd.
But the parser still complain that the 'title' in slideshow2.dtd is declared
more than once.
I use apache's Xerces.
I want to know if Xereces realy support namespace spec. now, or how to use
the namespace with a parser. Can anyone kindly tell me where to find some
material that demo the use of namespace in Java program.
Thanks for any help!!!

How to Add namespace to all elements in a xml document

Hi,
I am trying to read an xml file that does not have any namespace definitions. I have been able to create another schema in which i specify the namespace defination as shown below.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://TargetNamespace.com/AckPaymentFile_PL" targetNamespace="http://TargetNamespace.com/AckPaymentFile_PL" xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd" nxsd:version="DTD" elementFormDefault="qualified" attributeFormDefault="unqualified">
<include schemaLocation="PM_XML_FILE_ACK_SCHEMA_NO_NAMESPACE.xsd"/>
</xs:schema>
Once i do it, i am able to see the namespace has been assigned to the root element. I am looking for a way to assign the namespace and prefix tag to all elements in the xml document. If i don't i am unable to access any part of the xml document, keep getting please verify if xpath is correct.
Thanks
Sridhar

Hello,
Once you've answered all the above.
If you can run xpath that supports functions against the xml, the expression:
count(//phone)Otherwise, without leaving SQL:
select count(*) from
xmltable('//phone' passing
-- Your XML goes here, could be a table column with type XMLTYPE.
xmltype('<person><phone>123-456-7890</phone><phone>098-765-4321</phone></person>')
columns phone varchar2(24 char) path '/phone'
;

HTTP Post(partner 1)----------------->SOA--------------->HTTP Post(Partner 2).
I have cXML its in dtd format which i have converted to Native format using file-adapter and added namespace schema. so My question is while cXML is post to SOA i have added namespace schema and consumed it to my BPEL, while it leaves out Partner2 through HTTP post again the namespace should be removed and sent to partner 2. I am stuck at this Point. need Urgent help. please. how to remove name space.

In Your bpel process under assign activity give it as below
<copy>
ora:getContentAsString( ora:processXSLT( 'xsl/removeNamespaces.xsl', bpws:getVariableData('variable name','rootelement')))
<to variable="String"/>

String variable contains your xml message with out namespaces in string format.
You can pass this string content to your partnerlink 2.

Add Namespace in XPATH - Declaration - [JS]-CS4

Dear All,
Here I have a big doubt regarding for XPATH - Add Namespace in JavaScript.
I have to written in Vb.NET
//---------------- Add Namespace in VB.NET --------------------//
Dim xDom As New XmlDocument
Dim xNs As New XmlNamespaceManager(xDom.NameTable)
xNs.AddNamespace("ce", "http://www.elsevier.com/xml/common/dtd")
xNs.AddNamespace("aid", "http://adobe.com/4.0")
AuthorNds = xDom.SelectNodes("//ce:author", xNs)
//--------End
and using the xNs in anywhere, But I can't declare the namespace in Javascript+XPATH.
this.name = "AddReturns";
//XPath will match on every XML element in the XML structure.
this.xpath = "//ce:author";
// Define the apply function.
this.apply = function(myElement, myRuleProcessor)
Only is there in the XPATHs. So How to use and insert the namespace in the Javascript + XPATH operations.
Please kindly give me a suggestion to declare the XPATH in javascript....
Thanks & Regards

Is there a predefined $variable for the envelope?

Error opening external DTD 'Segnatura.dtd' using dbms_xmlsave.insertXML

I've been trying to insert a document in a table. All works fine
if the xml doesn't contains the doctype element!
If I add the row
<!DOCTYPE Segnatura SYSTEM "Segnatura.dtd">
to my xml I get the error:
oracle.xml.sql.OracleXMLSQLException: Error opening external DTD
'Segnatura.dtd'.
If I specify all the path "file:///temp/Segnatura.dtd" the insert
works, but I don't want to do in that way beacause I don't want
to modify the original xml that i'm inserting!
In the package dbms_xmlsave I have no ways to change the
basedir/baseurl
or to setValidationMode to false like in xmlparser package.
Is there any way to solve this problem??
Thank's in advance
Mauro
This is an example scratch of my xml doc:
<?xml version = '1.0' encoding = 'ISO-8859-1'?>
<!DOCTYPE Segnatura SYSTEM "Segnatura.dtd">
<Segnatura versione="2001-05-07"
xmlns:xml="http://www.w3.org/XML/1998/namespace" xml:lang="it">
</Segnatura>

Hy Steven, thank's for your attention.
I'm not using the xsql servlet.
I'm reading an xml file coming from the file system and I want to
import it in the db using a java stored proc.
I also have the dtd file (Segnatura.dtd) but I don't know where
to put in on the server.
If I run my java program and I put Segnatura.dtd in the execution
classpath on the program the xml is loaded fine.
If I load the stored proc in the db then I don't know where to
put the dtd. Do I have to put the directory containing the dtd in
the server classpath and the restart the db maibe?
thank's
mauro

Namespace declarations

I have an XML file that declares some namespaces in its root
element, like this:
<config-ui xmlns='ocfgui.dtd'
xmlns:cfg='ocfg.dtd'>
|
(innards deleted)
|
</config-ui>
When I run this though the Oracle XMLParser v2.0.0 with
validation on, I get "Illegal attribute name" errors on the
namespace declarations. It's true that they're not in my DTD,
but I didn't think the DTD had to specify xmlns attributes on
every element that could use them. I thought that as reserved
attribute names, they were implicitly valid on any element. Can
someone set me straight on this?
null

David, see http://www.jclark.com/xml/xmlns.htm which states that
the XML Namespaces Recommendation doesn't define additional
validity distinct from XML 1.0 validity, so the behavior of our
parsers is correct. There are two ways you can minimize size of
your document. Either namespace scoping/defaulting, or attribute
defaulting. See also section 5 of the following:
