SQL and XML Schema

I hope this is the right forum to post. I was wondering if there are any good tutorials or books on SQL to XML?
Basically I need to query accounts in the state of North Carolina that have recieved a certain document in the past day. That is a very easy task to do in SQL however the state of NC wants us to report our findings in a specific XML schema using nodes.
Luckily I have the schema which was given by the state of NC however not sure how to get my query to fit into the XML schema. Just wondering from a beginners perspective.
Sorry for the newbie questions.

The [XML DB Forum|http://forums.oracle.com/forums/thread.jspa?threadID=410714&tstart=0] is a good place to start.

Port and XML Schema

I wanted to configure the Port and XML schema for a repository.
I followed the following steps.
I have XML Schema file in my local disk. Then I created Port in the console.
However I am not able to see any folder structure getting created on unix server. The port was saved successfuly.
I can not see the Ready folder for this particular folder.
Can you please help me?

Hi SudhaViz,
Firstly create a remote system and associate that with the port.
You can find the port in the following path of that particular remote system.
C:\Program Files\SAP MDM 7.1\Server\Distributions\HostName_DB\Repository Name\Inbound\Remote_System\Port\Ready,
C being the drive where you have installed MDM Server
Thank you,

XDK for PL/SQL and XML Parser for PL/SQL

Is there a difference between the terms:
XDK for PL/SQL
and
XML Parser for PL/SQL V2
or are they the same thing...?
cheers,

XDK stands for XML Developer's Kit. There are Oracle XDKs for Java, C, C++, and PL/SQL. These development kits contain building blocks for reading, manipulating, transforming, and viewing XML documents.
XML Parser is one component of XDK. Other components of XDK are
XSLT Processor, XSU, XSQL Servlet, XML Class Generator, etc.
For more information on XDK and its components please refer to:

Which way to go with PL/SQL and XML

Hi fellows,
I have a general question to XML on Oracle.
I read already some parts of the three manuals coming with the online documentation of 9i
- XML developer kit XDK
- XML API - XDK and Oracle XML DB
- XML database developer guide Oracle XML DB.
Also I wrote already a PL/SQL package using DBMS_XMLGEN to generate XML data from relational Oracle tables.
Actually I like the simplicity how I can create XML data with this DBMS package but I still missing the features like using a DTD/XML Schema to generate XML data.
I still don't know what the best way would be to use these features of XML in Oracle.
Hopefully someone can give me some advise and possibly can point to some code samples so that I can see the proper use of the package.
How about DBMS_XMLQuery?
To use this package, would that be the better solution for my problem?
Any comment much appreciated.
Thanks
Fred

Hi Fred,
Having written a fair amount of PL/SQL code to generate and process XML in the past years, I can give you my opinion on the matter. If you look at the PL/SQL API's Oracle has been written to handle XML, you will find two types/categories of API's: PL/SQL code based on wrapping java (i.e. DBMS_XMLQUERY) and PL/SQL code based on C (i.e. DBMS_XMLGEN). The first category is usually slower, so I tend to use these only if there are no other options. You can measure execution times by executing the same query using both DBMS_XMLGEN. vs. DBMS_XMLQUERY.
I usually tend to store xml into relational tables by extracting the xml document in PL/SQL using the functions XMLType data type offers (i.e. extract, existNode, getStringVal, etc) function rather than using DBMS_XMLSTORE for flexibility reason (more control over what's being stored).
Besides the PL/SQL API's there are some rather neat SQL functions to handle XML (i.e. XMLElement, XMLForest, XMLAgg, XMLAttribute, etc) I like to use to build XML documents that are to complex for DBMS_XMLGEN. But, on the downside, I think these functions might cost considerable amounts of CPU, because behind the scene a DOM-tree is build in the SGA/UGA(?), especially on large XML structures or high concurrency systems. I have not measured this yet, so I say might.
Further, what I think is lacking from the Oracle API's in general is handing of CDATA sections and the fact that some XML functions default generate "pretty-printing" XML, which can not be switched of as far as I know. In my opinion XML should never be "pretty printed", because XML basically is about data transportation, not about lay-out. CDATA sections are not handled, even worse "<![CDATA[ ]]>" is being escaped (to &lt and &gt) and not properly interpreted when processed back to text.

Webservices and xml schema valdiation

Hi everyone,
I have a method call thru web services, where the xml document comes as a string. I need to validate the xml document using xml schema. I have searched the xerces and dom4j apis, but couldn't find anything which allows me to validate an xml document, coming as a document, or as a string (not the location to the file system).
can anyone help with any resource site, or any code , thats going to be of great help.
thanx

DOMParser parser = new DOMParser();
parser.setFeature("http://xml.org/sax/features/validation", true);
parser.setProperty(
"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
"test.xsd");
hope this helps.

Validation with jaxp 1.3 and xml-schema

I'm totally green when it comes to xml&jaxp. Using jse 1.5 (jaxp 1.3), I'm trying
to have my app parse and validate an xml doc with xml schema. I want the validation to
happen using the schema specified in the xml doc. Also, I'd prefer if my application didn't have to set
the schema to use. As far as I can make out though, it appears that I need to parse the schemaLocation when
I want to validate using xml schema. Anyone know a way to avoid that step?
If not, then any idea why I'm getting the following err?

     documentFactory.setValidating(true);
     DocumentBuilder builder = documentFactory.newDocumentBuilder();

     I would anticipate being able to have the parser see the XSD reference in the XML and
     apply it. Anyway, here's code to programmatically specify an XSD to use for validation....
     documentFactory.setAttribute(
     "http://java.sun.com/xml/jaxp/properties/schemaLanguage",

Query resultset to xml using java and XML schema

Hi,
I query data using JDBC and I want to store it to an XML file which has a well defined XML schema. I searched a lot in the forum but did not find an answer. Please guide me to create this program.
I have managed to use JDBC to get result set but I do not know how to export is to XML using XSD and Java.
Please help.
Regards,
Ravi

I have managed to use JDBC to get result set but I do
not know how to export is to XML using XSD and Java.Export using XSD? Schemas are for validation.
Iterate through the result set, and build up the XML stream by creating an entry for each row.
Another way to do it is to load the ResultSet into a Java object and serialize that to XML using something like XStream.

Trouble Using Netbeans and XML Schema

I am currently experimenting on using XML files to store data for a game that I am developing. I had been using NetBeans 5.5 to validate my XML Schema (I am still new to XSD); however, now I am getting errors and have been trying for the better part of the week but am still unable to resolve them. Here is a clip from one of the schemas:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:cdt="http://JoaL.blissfulTragedy.com/Characters"
           targetNamespace="http://JoaL.blissfulTragedy.com/Characters" >
    
    
    <xs:simpleType name="name">
        <xs:restriction base="xs:NMTOKEN">
            <xs:maxLength value="15"    />
            </xs:restriction>
        </xs:simpleType>
... When I validate the XML (the two down arrows) I get the following errors for every restriction I have declared:
s4s-att-invalid-value: Invalid attribute value for 'base' in element 'restriction'. Recorded reason: UndeclaredPrefix: Cannot resolve 'xs:NMTOKEN' as a QName: the prefix 'xs' is not declared.After retyping the file three times I tried one of the stock NetBeans schemas, which will produce the same error whenever I add a restriction through the UI.
Any advice will be greatly appreciated :P

I think this is a dirty great bug in the Sun version of the apache Xerces classes that were bundled with jdk1.5.
I've had similar problems, and it seems to boil down to the fact that the NamespaceSupport class's getURI method does == instead of .equals when looking up the uri for a particular prefix. I'm told that this is a deliberate feature for the Apache stuff, and that the class assumes interned strings or strings that have gone through their internal SymbolTable mechanism, and that I can work around it by using interned strings. However, it is one of their classes that fails to intern the string (or put it through the symbol table etc.), so that doesn't really make sense as there are no hooks into this stuff.
They have even marked the bug as closed/fixed, and I'm attempting to re-raise it at present (so it'll be fixed in about ten years then).

OLEDB Dataconnection and XML Schema

Hi,
I create a form with fields binding with a OLEDB dataconnection.
It's work, I can request my database and store my data.
I want to be able to can access these field in a process (with workbench ES).
If I bind fields with a xml schema I can access to them and manipulate them but I can't bind them with a OLEDB dataconnection and a xml schema.
How can I do this ?
Thank you and I hope you could understand me :D

Yes, I have a DB but I am already working with the XML file. The Data Connection that I am using has this config:<br /><br />XML Schema<br />Schema file: contents.xsd<br />Options: <contents>, no checkboxes activated<br /><br />My solution is supposed to run online in a LAMP env, when the user clicks a Print Button, I run a script to generate the XML from the DB, and then I open a new page with the PDF form that I've built in LC Designer (8.0) with the generated data. I don't need data navigation, it's a summary report that will be printed.<br /><br />So, while developing, I've saved a populated XML locally and keep trying to open the PDF file with the data without success. Same if I save the 3 files (xsd, xml and pdf form) in the server and try to open the PDF through browser. But, as I said before, when previewing it in LC, I see the form exactly as I want.<br />I did what you mentioned (import data in Adobe Reader), and it worked partially, since the repeating row just showed one record.<br /><br />As I can see, I need some kind of script in the PDF form that, when it's loaded, the data (XML file) is imported. By now, I am trying to do it locally and think this should work. Then, for the online solution, I thought that I would need something running on the server, and based on what you said, I will need LC Forms, is that correct?<br /><br />Hope things are clearer now. Answering to your question, my form is binded globally. The repeating row is connected (Default Binding) to > $record.content[*] < and each field in the row connected to an item from the XSD definition. No Import/Export Bindings in use.<br /><br />Thanks for the help so far! :)

XDK and XML Schema

Hello All!
I am using standalone Oracle XDK for C 9.2.0.2.0 on Windows NT 4.0. The fragment of my XML schema is shown below:
<xsd:simpleType name="Text30">
<xsd:restriction base="xsd:string">
<xsd:maxLength value="30"/>
</xsd:restriction>
</xsd:simpleType>
<xsd:simpleType name="CCode">
<xsd:restriction base="xsd:string">
<xsd:pattern value="\d{5}|\d{8}|\d{12}"/>
</xsd:restriction>
</xsd:simpleType>
<xsd:complexType name="ReferenceNo">
<xsd:simpleContent>
<xsd:extension base="Text30">
<xsd:attribute name="cCode" type="CCode" use="required"/>
<xsd:attribute name="docDate" type="xsd:date" use="required"/>
<xsd:attribute name="TIRPageNo" type="TIRGreenPageNo" use="optional"/>
<xsd:attributeGroup ref="DeclarType"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
And the part of the instance document looks like:
<DocNo cCode="10501000 ... />, where "DocNo" is of type "ReferenceNo".
Then validating my XML document I am always getting error that my "cCode" attribute doesn't match
pattern. After removing <xsd:pattern value="\d{5}|\d{8}|\d{12}"/> from schema all seems to be OK.
Why? Where is the error? "\d{5}|\d{8}|\d{12}" is a valid regexp according the W3C XML Schema specification.
Any help will be appreciated. Thanks.

I have tested the same examples with XML Spy 4.4, MSXML 4.0 and Xerces-C 1.7.0.
All parsers have validated this examples without any errors... except XDK.

Regular Expressions and XML Schemas

The standard regular expression syntax in JDK1.4 doesn't support some of the constructs used by pattern facets in XML schemas.
For example the "Name" type is specified by the pattern "\i\c*" but the java.util.regex regular expression handler throws an exception when it encounters this with the following message:
Illegal/unsupported escape squence near index 1
Is anyone aware of any regular expression java libraries or tools that will cope with the XML syntax?

Thanks, but perhaps I should clarify. I realise that \i\c* is invalid syntax in the java regexp handler. My point is that in XML Schema regular expressions \i is meaningful - in fact it means
"the set of initial name characters, those matched by Letter | '_' | ':' "
I was wondering if anyone knew of a regular expression library that understood and correctly interpreted that.

Using PL/Sql And XML

Hello,
Am trying to use the xml packages from pl-sql. Could someone please tell me what priviliges are required to use these package fully. I also guess that public synonyms should be set up.
Tia.
Rgds.
Kim.

I have checked that the XML parser is installed using the suggested select statement. It seems ok.
Logging in as dba user, using Desc xmlparser is ok.
Created user XmlTesting, granted the roles javauserpiv and javasyspriv to this user. Desc xmlparser give error sys.xmlparser does not exist.
More thoughts appreciated.

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by ilho Ye ([email protected]):
You first need to install XML parser for java since XML parser for PL/SQL depends on it.
Try this SQL and see if Oracle XML parser is already installed on your machine.
select substr(dbms_java.longname(object_name), 1, 30) AS class, status
from all_objects
where object_type = 'JAVA CLASS'
and object_name = 'dbms_java.shortname('oracle/xml/parser/v2/DOMParser');
If you see the result that status is valid and class is 'oracle/xml/parser/v2/DOMParser.
Then you are good to go.
secondly try this after connecting sqlplus
describe xmlparser
If you do not get anything, then you need to install XML parser for PL/SQL.
You can download it in which there is a readme that would help you to install from technet.
Also make sure that you grant javauserpriv and javasyspriv privilege to the one who is going to execute XML.
When you finish up installing all this, try the command, describe xmlparser again.
If you now see the result, you are all set.
From now on you can run PL/SQL to access and retrieve XML.
Hope this helps !!! <HR></BLOCKQUOTE>

Jax-ws and xml schema

hello,
i'm developping a web service that returns an object person(String name, int age) as result, when generating my wsdl using jax-ws I've found that just the name of the xml schema representing my object person is present (relatif path), so i want either to generate the absolute path in my wsdl or to incorporate the xsd in it.
thanks.

Sax and xml schema

Quick question
Can you use SAX with XML Schema? or SAX will only work on DTD?
Thanks!

sax can use either
i believe all that is needed is calling
setNamespaceAware(true) on the parser factory to use xsds (along with setValidating(true))
