Identifying an XML document type

I am reading XML message off a queue using JMS and I want to determine the XML document type so I can use the proper schema for validation. Since different XML documents will be coming in off the same queue I need to determine the document type so I can use the proper schema for validation.
Is there a good way to do this? So far I have been doing the following but I am looking for a better solution:
*Use the JMS headers to store the XML message type. Not always possible.
*Read the first few lines of the XML as a file and parse for the root node or .xsd.

What I am refering to is a situation where I have one queue that has multiple incoming XML documents.
For example:
PurchaseOrder.xml needs to be read off a queue validated via PurchaseOrder.xsd
PartsOrder.xml needs to be read off the same queue and validated with PartsOrder.xsd. I am trying to find and eloquent solution to identify if I have a PartsOrder or a PurchaseOrder, so I can set the proper schema for validation when parsing the XML doc.

Document types - wildcard support?

My understanding of iFS is that I can define an XML document type, and after that any documents of that type would be automatically parsed for me. In another message there was a note that currently wildcards aren't supported. I'm not clear on this. How about this example: I have an XML document 'order.xml', that I 'define' into iFS. Subsequently any documents called order.xml will be parsed - right?
ok, but what wouldn't work is sending documents called order100.xml, order101.xml... because I'd have to define the format for each one? Right?
Thanks! I can't get the *()& thing to work, so I'm going at this by just reading.

Wildcards don't work in the Parser mapping tables. Eg you cannot map x* to a particular parser.

Oracle Fusion Middleware 11G B2B Document Type not getting Identified

Hello,
I have installed Oracle Fusion Middleware 11g on my local machine and created a custom document type with proper .xsd definition and XPath Expression Identifier in Oracle B2B interface and configured its trading partners ( Host & Remote ) along with an agreement between the partners.
I have also configured the host listening channel of Generic-File type which picks xml files from my c:\orclsrvs_in folder.
My problem is that the moment I drop any sample file in the expected directory, it gets picked up from B2B , but there isn't any record of the same under Reports and Metrics links.
The Business message, Application message and Conversation message tabs are also not showing any information about the record picked, but in wire message tab, the record is shown in PROCESSING state.
I am not able to conclude whats wrong behind this.. where can i track the logs for the same ??
kindly help to resolve this issue.
Thanks & Regards

Hi Hitesh,
i came to know that B2B extracts the TP name from the filename itselfYes, in case of Generic File, Generic SFTP and Generic FTP, file name provides the necessary values to Oracle B2B to identify the Trading Partner. You can define your own file name format in the Delivery Channel under Transport Protocol Parameters in field "Filename format" (It's an optional field but it is always good to define your own format, otherwise B2B will take it's default format - TradingPartner_DocumentType_Revision_msgType_msgId_replytoMsgID_extension.xml ). Following Filename formats can be used -
%FROM_PARTY%
%TO_PARTY%
%DOCTYPE_NAME%
%DOCTYPE_REVISION%
%MSG_ID%
%TIMESTAMP%
These file name formats can be used in any combination; for example,
%TO_PARTY%_%DOCTYPE_NAME%_%DOCTYPE_REVISION%.dat
Note - Any file extension is allowed.
what are the system parameters to be set in weblogic console and how?? This activity is part of the pre and post installation steps. If you have done those without getting any errors then nothing else is required.
how shall I reinstall XEngine properly ??XEngine is part of B2B installation. If B2B gets installed without flashing any errors then we assume that other components of this part has installed properly.

Problem to validate XML document if the type of root element is abstract

I have the following XML document:
<?xml version="1.0" encoding="UTF-8"?>
<ct013/>
It corresponds to the following XSD Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
     <xs:element name="ct013" type="foo"/>
     <xs:complexType abstract="true" name="foo"/>
     <xs:complexType name="fixedType">
          <xs:complexContent>
               <xs:restriction base="foo"/>
          </xs:complexContent>
     </xs:complexType>
</xs:schema>
Please take attention to the fact that the type of root element of that BDD is abstract.
XML Schema provides a mechanism to force substitution for a particular element or type. When an element or type is declared to be "abstract", it cannot be used in an instance document. When an element is declared to be abstract, a member of that element's substitution group must appear in the instance document. When an element's corresponding type definition is declared as abstract, all instances of that element must use xsi:type to indicate a derived type that is not abstract.
Declaring an element as abstract requires the use of a substitution group. Declaring a type as abstract simply requires the use of a type derived from it (and identified by the xsi:type attribute) in the instance document.
For more information of using abstract types please see chapter 4.7 Abstract Elements and Types of XML Schema Part 0: Primer Second (http://www.w3.org/TR/xmlschema-0/#abstract).
In this case there is Oracle bug when I try to validate this XML document using Oracle XDK:
String validate(String xml, String schema)
throws XSDException, XMLParseException, SAXException, IOException
System.setPropert("oracle.xml.parser.debugmode", "true");
XSDValidator xsdValidator = new XSDValidator();
XMLError xmlError = new XMLError();
xmlError.setErrorHandler(new DocErrorHandler());
XMLDocument xmlDocument = parseXMLDocument(xml);
XMLDocument schemaXMLDocument = parseXMLDocument(schema);
XMLSchema xmlSchema = (XMLSchema) new XSDBuilder().build(schemaXMLDocument, null);
xsdValidator.setError(xmlError);
xsdValidator.setSchema(xmlSchema);
xsdValidator.validate(xmlDocument);
return getValidationError(xsdValidator);
I get the following error:
Can't find resource for bundle oracle.xml.mesg.XMLResourceBundle, key XSD-2046.
I tried to validate this XML document using two other libraries - XSD Schema Validator (http://apps.gotdotnet.com/xmltools/xsdvalidator/Default.aspx) and xsdvalid-29 (http://www.w3.org/XML/Schema#XSDValid). Both libraries pointed me on the error that the type of root element is abstract and it cannot be used for doing validation.
I think that Oracle should return me explaining message but not to throw exception.
Am I right? Is there really Oracle bug or I miss something?
Any help, hits, advices would be gratfully apriciated.

Define Element1 as follows:
<xs:element name="Element1">
<xs:complexType>
<xs:complexContent>
<xs:restriction base="xs:string"/>
</xs:complexContent>
</xs:complexType>
</xs:element>
Does the XML document get validated if the element is specified as
<Element1></Element1>

Adding XML Declaration and Document Type Declaration.

I'm using Oracle's XML Class Generator C++ version 1.0.2.0.0. I can create classes from a defined external DTD and create my XML document. But the document does not contain the XML Declaration <?xml version='1.0?> nor does it contain the Document Type Declaration <!DOCTYPE root-element-name SYSTEM "system-identifier">. What do I need to do to get these as part of my XML document? Does the class generator have methods to do this? Could someone show me an example?

If you invoke the print method on the top-level ELEMENT, you get
just the body of the document with no DTD or XMLDecl. if you invoke
print on the top level NODE (the DOCUMENT node), then the output
document will contain the XMLDecl and DTD.
So please try to print from DOCUMENT node.

Identify individual elements in repeated elements in an XML document

Hello,
I'd like to identify individual elements in repeated elements in an XML document.
For example a table 'dataXML' which has a column 'sample' (XMLType). If I have an XML document such as,
<ELEMENT>
<PO>
<PONO>100</PONO>
<PONO>200</PONO>
</PO>
</ELEMENT>
I can use //PONO[1] to identify the first "PONO" element (with value 100) and //PONO[2] to identify the second "PONO" element in the document.
If I write this query:
select L.sample.extract('ELEMENT/PO/PONO/text()')).getStringVal()"SAMP"
from dataXML L
I'll receive this result:
SAMP
100200 (the first row)
And if I write this query:
select L.sample.extract('ELEMENT/PO/PONO[1]/text()')).getStringVal()"SAMP"
from dataXML L
I'll receive this result:
SAMP
100 (the first row)
But I'd like the following result:
SAMP
100 (the first row)
200 (the second row).
Could you help me, please?
Thank you very much.
Melissa Lemos

you have to use something like this.
select extractvalue(xmltype_column, '/Name/@attributename')
from table_name

List all documents types in a XML file...

Hi, i want to list all document files that are on the portal and make a XML file with result. I found the Interface Query where i can use "search" method. Is there a way to use the APIs from hyperion, i try to do a servlet and obtain a list of all document type like with NAME, DATE CREATED, TYPE, UUID, DESC, etc.. The list can be order by NAME, DATE, etc... And put the result in a XML file. Is it possible to do this with that Hyperion API, or i spend my time to find the solution with this restricted/limited APIs? And first, is there a documentation for the developpers on what we can do with API's Hyperion? The JavaDoc Hyperion just give a little bit information, nothing consisting!! Thanks in advance for any help : [email protected]!Max

Help - Inserting an XML document into a Oracle 8i Column (CLOB Type)

Hi JavaGurus,
I am looking for a simple java code which will take my XML document as input and insert the same into a Oracle 8i database's column which is of type CLOB.
Insert statement won't work and I can not use SQL Loader.
Any one?
JK

Maybe you can adapt some of the code in Oracle's "LOB Datatype" example, which is a complete working program that stores and retrieves BLOBs and CLOBs.

Example for calling document type service using a XML

Hi,
Can anybody give me some pointers to any examples about Document type webservice
that is passed an XML document? The service expects a custom java object.
I am running WLS 7.0 with sp2.
This is what i have done so far:
I have created a document type web-service with the following signature
public CustomReturnObject provideService(customParameter) { }
The 'customParameter' is based on a "CustomParameter.xsd" and 'CustomReturnObject'
is based on its schema. I ran the "autotype" to generate the java classes for
the schema.
Now, we would like to invoke the service by passing an XML document instead of
calling it by creating instances of "CustomParameter" java class. Also we would
like to get the XML represented by "CustomReturnObject" in the client program
instead of the java object.
Can anybody help?
Thanks
Raghu

The latest version of WLS is 8.1.
I think the the "endpoint" needs to be string.
String endpoint =

How to set Document Type Declaration of xml Document?

Hi,
I am referring to "org.w3c.dom.Document".
How can we set the Document Type Declaration (DTD) of a document?
Thanks.

Hi,
But when we have to create a document(org.w3c.dom.Document) dynamically, and that document has to be validated against a DTD......How can we do it?
I am using the following code
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
DOMImplementation domi = builder.getDOMImplementation();
DocumentType docType = domi.createDocumentType("query", null, "c:\\queryDtd.dtd");
Document doc = domi.createDocument(null, "query", docType);But this code is not working. Resulting document is not having <!DOCTYPE...> tag
I have to build a Doument object (not xml file) whose content is as below
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE query SYSTEM "queryDtd.dtd">

Encoding Type XML Document

Hi,
I have an XML document which is essentially data pulled from the craigs list website. It contains alot of Ampersands and pound signs and other stuff which i have been told does not follow the UTF-8 encoding which i put in the tag at the top of the document. Could someone tell me what the correct encoding would be so that i can parse the file using the Java DOM parser without it throwing out errors such as;
Invalid byte 1 of 1-byte UTF-8 sequence.
Thanks Alot
Richard.

Sounds like you don't know too much about XML and encoding. Try reading this tutorial, it's long but it's thorough:
[http://skew.org/xml/tutorial/|http://skew.org/xml/tutorial/]
That should take care of the XML part. Now you need to know the Java part: the simple rule is to not create XML documents if you don't know what encoding they will have. Your best bet is to write them using UTF-8 in the first place. I don't know how you're writing the documents but my bet is you're using plain old Java I/O. In that case use an OutputStreamWriter which specifies UTF-8 for the encoding. Here's a link to the Java I/O tutorial if you don't know how to do that:
