XML Schema Definition validation
Hi all,
I am trying to find the right way to get validation errors out of a xsd file - I found a couple of ways to do this but none of them seem to be the "right" way...
(BTW, I am using Xerces 2.6.2)
The first option was to validate the xsd against it's own xsd (http://www.w3.org/2001/XMLSchema.xsd) - but that's kind of stupid since the parser already knows what an xsd should look like and should be able to provide "smarter" errors besides mere structural ones.
The second option is to set the xsd which I want to validate as the schema source to some pseudo xml which I parse only to get the errors in the xsd....
something like this:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
spf.setValidating(true);
SAXParser sp = spf.newSAXParser();
sp.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
sp.setProperty(JAXP_SCHEMA_SOURCE, xsdForValidation);
sp.parse(new InputSource(new StringReader("<root></root>")), new MyHandler());This is really stupid but as a result MyHandler gets notified about error in the xsd file, which is what I am interested in.... The problem is that I obviously get error reports for my pseudo xml..... How can I differentiate between the xsd errors and the xml errors I am reported about? there is nothing in the error data indicating if it came from the schema-source or the xml itself....
What am I missing here? How can this reasonable need be so annoying to implement?
Some of the Schema Editors validate a schema.

[11g] XML Schema full validation with binary XML ?
Hi,
Oracle's doc quotes " Loading XML data into XML schema-based binary XML storage causes full validation against the target XML schemas. ".
After registering this XML Schema which indicates that a company must have at least a code, name and pilotes element :
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xdb:storeVarrayAsTable="true" version="1.0">
<xsd:element name="compagnie" type="compagnieType"/>
<xsd:complexType name="compagnieType">
<xsd:sequence>
<xsd:element name="comp" type="compType" minOccurs="1" xdb:SQLName="COMP"/>
<xsd:element name="pilotes" type="pilotesType" minOccurs="1" xdb:SQLName="PILOTES"/>
<xsd:element name="nomComp" type="nomCompType" minOccurs="1" xdb:SQLName="NOMCOMP"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="pilotesType">
<xsd:sequence>
<xsd:element minOccurs="1" maxOccurs="unbounded"
name="pilote" type="piloteType" xdb:SQLName="PILOTE"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="piloteType">
<xsd:sequence>
<xsd:element name="nom" type="nomType" xdb:SQLName="NOM"/>
<xsd:element name="salaire" type="salaireType" minOccurs="0"
xdb:SQLName="SALAIRE"/>
</xsd:sequence>
<xsd:attribute name="brevet" xdb:SQLName="BREVET">

<xsd:restriction base="xsd:string">
<xsd:minLength value="1"/>
<xsd:maxLength value="4"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:attribute>
</xsd:complexType>
I can therefore insert a row no valid into this table
CREATE TABLE compagnie_binaryXML_grammaire OF XMLType
XMLTYPE STORE AS BINARY XML

ELEMENT "compagnie"

5 <nomComp>No pilot and no comp!</nomComp>
6 </compagnie>').CREATESCHEMABASEDXML('http://www.soutou.net/compagnies3.xsd'
1 ligne crÚÚe.
Unless the following instruction is done, no valid XML file can be added.
ALTER TABLE compagnie_binaryXML_grammaire
ADD CONSTRAINT valide_compagniebinaryXML
CHECK (XMLIsValid(OBJECT_VALUE) = 1);
Where is the difference between the behaviour of an object-relational table ?My guess is that the virtual column spoils the soup (could you check).
The following works for me on 11.1.0.6.0.

Thank You,
Supreet RHi Sivaram,
Unfortunately, the 8.1 IDE did not have special tooling for schema generation.
You will need to create it by hand or using an external tool
If you are using an external tool to create the file within the schema project, you might want to disable the schema project auto build, which will be triggered every time a file save takes place
cheers

How to generate WPF Xaml through XSD (xml schema definition)
Hi Experts
I am working on Projects where we need to generate wpf ui (xaml) at runtime as per different requirements. We are trying to generate xaml from xsd file. We are able to generate UI from xml but as size of xml can be large we are reluctant to use xml as xaml
generation source. I am attaching a sample image what we are trying to do
UI elements Description
For each complex node in xsd, we need a panel which can have add or delete button depending on minoccurs and maxoccurs of the node. Inside panel we want to add different ui elements.
Please suggest if there is any way to do this or any one have worked in this direction?
Thanks
PraveenI should think you could use xsl on xsd to generate xaml.
I have used xsl on xml to do this sort of thing - for reporting style stuff.
Xsd is just an odd kind of xml so I should think that's do-able.
Failing that.
You could use the template approach and generate xml from that but use c# to read the xsd.
You would have like a textbox template etc.
Is that UI truly representative?
You could leverage the approach I use in this:
http://social.technet.microsoft.com/wiki/contents/articles/29777.wpf-property-list-editing.aspx
The EditRow user control has label + editing control as a pair.
You would add another control for that pattern thing I see in grey after some of those.
But you could essentially iterate the fields in an xsd , decide what control to use based on field type.
Set the label....
Add that to a Listbox.
You have a big bunch of xsd and you're thinking of generating the UI?
I suppose you could then use icustomtypeprovider to generate matching viewmodels inheriting some base vm functionality.
I don't follow how a "supporting dll" comes into this.
Could you explain?
Hope that helps.

Is it possible to modify the XSD file used by BPEL Designer to evaluate my BPEL Project?
The XSD file is:
http://schemas.xmlsoap.org/ws/2003/03/business-process/Hi,
I also like to add a tag to the invoke activity.
But I always get the warning: the extension element is unknown.
Have you got any examples or tutorials how to extend the activity?
1.) how does an example xsd-file look like?
2.) what is the namespace of it to reach it from the bpel-file
3.) where do I store it: in the mywork folder?
Thanks. -
I have a question, if in the XDK there is a
possibility to check a .xsd file, if it belongs to the XML Schema Definition http://www.w3.org/2000/10/XMLSchema
Thanks for your help
Greetings, Merry Christmas and Happy new Year
AndreasSimply use the self-same XML Schema Processor to validate your *.xsd schema against the schema for XML Schema itself. That is, the XML Schema spec "ships" with a normative XML Schema which describes the valid elements that a schema author can use to write a schema. If you have a particular XML schema definition in hand, it is in particular an instance of a document that should be valid by the XML schema for XML Schema, if you've done it correctly.

Hi all,

It worked nicely. But, I just found out the coding that was downloaded from the website of Apress and I just executed was different from the coding of Listing 4-8 listed in the book: all the <xs: ....> and </xs: ..> in my SSMS2012 are
listed as <xsd:...> and </xsd:...> respectively in the book!!?? The same thing happens in the Listing 4-3 Simple XML Schema, Listing 4-5 XML Schema and Valid XML Document with Comple Type Definition, Listion 4-6 XML Schema and XML
Document Document with Complex Type Using <sequence> and <choice>, and Listing 4-7 Complex XML Schema and XML Document with Model Group Definition (I executed last week) too. I wonder: should xs or xsd be used in the XML
Schema Collection of SSMS2012? Please kindly help, clarify this matter and explain the diffirence of using xs and xsd for me.
Thanks in advance,
Scott ChangHi Scott,
Using xs or xsd depends on how you declare the namespace prefix.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="item">
I've posted a very good link in your last question, just in case you might have missed it, please see the below link.
Understanding XML Namespaces
In an XML document we use a namespace prefix to qualify the local names of both elements and attributes . A prefix is really just an abbreviation for the namespace identifier (URI), which is typically quite long. The prefix is first mapped to a namespace
identifier through a namespace declaration. The syntax for a namespace declaration is:
xmlns:<prefix>='<namespace identifier>'
If you have any question, feel free to let me know.

Specifying Case-Insensitive Element Names in XML Schema
Hope someone knows this!
Is it possible to define an an XML Schema Definition so that Element names in the target XML File can be case insensitive.
At the moment my Parser throws an error if the element names in the XML file do not have the exact same case as the definition in the XML schema.
E.g
In Schema i have:
<xsd:element name="HOSTINVENTORYLINE" type="HostInventoryLineType" maxOccurs="unbounded" minOccurs="0"/>
but in xml file i have
<HostInventoryLine field=""/>
or
<hostinventoryline field=""/>
Does anyone know anyway to get around this, so that the parser accepts the HostInventoryLine element in the xml as an instance of the HOSTINVENTORYLINE element defined in the schema.
Thanks in Advance
JJ
Message was edited by:
[email protected]You could use substitution groups to handle this. You would need an entry in the schema for each valid capitalization. This won't scale well if you want to be completely case insensitive, but if you only support lower case, upper case, and camel case it should do the trick.

Hi,
I need to load some XML schema definitions to afterwards validate some DOM documents against this schemas. My problem is, when loading those XML schema definitions I have to validate them. How to do this? How to provide an javax.xml.validation.Schema object and check is valid XML schema?
Thanks in advance.The very act of loading the schema into a schema object will validate it. That is, if you get as far as having an instance of Schema, it's valid.

Using XSDBuilder to build XML Schema objects
I want to parse an XML document using an XML Schema Definition that I provide explicitly to the parser, rather than one identified in the document being validated. It appears that I can create an XML Schema object using XSDBuilder, and give it to the XML parser using XMLParser.setXMLSchema(). The problem is that XSDBuilder.build() wants an XSD system ID that is a file, and I want to retrieve XSD documents from non-file-based stores. Ideally, I'd like to give the builder a stream containing the XSD, or barring that, provide a custom entity resolver that it can use. Any ideas how to go about doing that? Or am I going about this the wrong way?
Thanks for any advice,
markl
nullHi,
I didn't test it wit XML Schema, but any parser that finds a system ID should call an implementation of EntityResolver that returns an InputSource for the system ID.
An InputSource is a wrapper around an InputStream and its url and it ssystemID.
An example for sun's parser is on http://www.s-line.de/homepages/gerd_castan/java/resolve.html
(I "tested" this code also with oracles DTD and Schema parser. This means that I used this code for oracle, too, but I didn't go through the debugger to see what it does.)
Cheers,

GetXMLSchema java method generates invalid XML Schema document
Hi all,
I managed to get the xdk FAQ demo to work eventually on oracle 9.2.0.1.0 for windows, I noticed however that when I generate an XML Schema definition against a query, the document contains an outdated namespace declaration (minor flaw) and "nullable" attributes instead of "nillable", resulting in an invalid XML Schema document when edited with certain tools like Altova's XmlSpy.
How can I fix this?
See below for the XML Schema source.

Do you want XMLSPY to convert it to the new one:

When I click "Yes" and save, I get a perfectly valid schema (with nullable replaced by nillable). -
XMLType column based on XML Schema: several questions
Hi,
I've a table on an oracle db version 10.1.0.4 where I stage the xml files containing orders created on a third party's system using BizTalk.
Although the storage I opted for is based on an XML Schema, defined by this third-party, I am facing big perfomance issues with files bigger than a few hundreds of kBs.
For instance, a 32Mb file takes more than 2 hours to be processed.
Now, after reading other threads in this forum and the documentation, my understanding of the problem is that the whole issue is with the correct indexing of the nested tables.
Here is my current XML Schema definition:

When I registered the XMLSchema, the following types and tables were automatically created and you can see the hierarchy below:
(by the way, I could not find any xdb_utilities.printNestedTables mentioned elsewhere)

These objects are then used in the following nested tables:

Note that I cancelled this operation before it was over so I imagine that these figures refer to the statistics as of the time when the operation was interrupted.
So, here are finally my questions.
In order to create the constraints on the nested tables as shown in other threads, do I need to drop the existing xml_orders table and ancillary object types and recreate them or is there a way to add such constraints using the existing system generated object names?
Secondly, the xml_orders table may contain severale documents, not just one and his current primary key is the column ID. So, in order to uniquely identify the deepest element in the xml document, I need first to select the relevant document by means of the id column.
Would it be better to create the indexes containing this id column together with the nested_table_id and array_index?
Thanks for you help.

PS: I wrote a 10 lines xsl transformation that I passed on to Saxon together with the 32Mb file. It took less than 1 minute to produce a flat file that was loaded almost instantly by SQL*Loader. So, what I am looking for is a procedure loading this stuff in less than 2 minutes or possibly less.Does the following help

Problems using mathml XML Schema in XMLDB
I have successfully loaded the hierarchy of XML Schema definition documents for the current 'mathml' by adjusting the relative paths in all include and import statements, and by forcing the load to overcome cyclic dependency issues.
However when I try to create a table using the XMLTYPE or register another schema which is dependent on mathml I receive the following error:
ERROR at line 1:
ORA-31079: unable to resolve reference to group "Content-expr.class"
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 37
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 61
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 126
ORA-06512: at line 14
Having tried loading into both 9iR2 and 10GR2 databases and pasting the document containing the 'Content-expr.class' into the parent document (i.e. removing the include) I have come to the conclusion that there is a problem with the schema definition.
However being new to XML I do not know what ths issue is as the file containing the definition (math.xsd) is included well before the references in the parent document.
Here is the group definition corresponding to the offending reference:
<xs:group name="Content-expr.class">
<xs:choice>
<xs:group ref="ContExpr.class"/>
<xs:group ref="PresExpr.class"/>
</xs:choice>
</xs:group>
I am also unable to trace which reference is causing the problem as there are several.
Does anyone have any suggestions as to what could be causing this issue, or how I can obtain further diagnostics?
Any help much appreciated.

*********** New info ***************
OK. I have tried further to register the schema, and have the following additional information.
I determined that I thought my problem was cyclic dependencies being resolved ONLY by virtue of the parent file mathml2.xsd. I therefore pasted all the files together in include order so that this was no longer an issue. I then performed the following actions:
1. I tried to register into Oracle 9iR2 database (9.2.0.4) and received the following error:
ERROR at line 1:
ORA-31151: Cyclic definition encountered for group: "Content-expr.class"
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 26
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 131
ORA-06512: at line 14
2. I then tried registering the schema into an Oracle 10G Release 2 database as well, and received the following error:
ORA-31084: error while creating table "MEDLINE"."math729_TAB" for element
"math"
ORA-01792: maximum number of columns in a table or view is 1000
ORA-02310: exceeded maximum number of allowable columns in table
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 37
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 61
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 126
ORA-06512: at line 14
My conclusions are as follows:
1. 9iR2 (the version I was using at least 9.2.0.4) can't handle cyclic dependencies at all, or at least not complex ones.
2. Neither 9iR2 or 10gR2 can handle cyclic dependencies (or other dependent definitions managed purely by virtue of a parent file with multiple include statements)
3. 10gR2 can handle cyclic dependencies when they are all defined in the same file or resolved by an explicit include regardless of complexity.
4. 10gR2 cannot handle highly complex XML Schema definitions due its limit of 1000 columns per table.
Does anyone have any comments on these conclusions?
I don't even want to handle Mathml, just another schema definition that imports it. I may try to make my own adjustments.

nullThanks, I found the relevant sections in the XML DB 10GR2 documentation (chapter 3 I think). As far as I can tell my options are to either use one of the following:
- top-down technique creating tables for sub elements in the schema definition
- bottom-up technique collapsing some of the lower elements into CLOBs (I guess this is semi-structured storage)
The problem with Mathml is that it seems quite complex, with only one global schema element and many nested elements, hence only one table is created by XMLDB and it logically follows that we run out of columns.
To get it to work is likely to involve a fair amount of manual schema modification, which incurs a maintenance overhead for me.
It would be good if Oracle could provide a way of simplifying this maintenance of complex schemas to get them to be registered. I guess this would be increasing the number of columns alllowed for a table or offering some other parametric option for DBMS_XMLSCHEMA.REGISTER_SCHEMA that allowed a threshold and either a top-down or bottom-up approach to be taken automatically.
For the time being I am using a simplified schema that does not depend on Mathml for my storage needs. -
Unable to create xml from xml schema
JDeveloper 10.1.3 EA1
I am unable to create a new xml file from an xml schema when the starting root element is a complex type (but it works with a simple type). It does not matter if the xml schema is registered within JDeveloper.
Is this a bug or intended behaviour?
Error message:
''XML Document from XML Schema creation could not be competed succesfully. Make sure the source schema is valid and that you have write permissions to the output directory."
NB The xml schema is valid and I have write permissions on the specified directory.When I do not register this (or other) schema with JDeveloper, I can create an xml document from xml schema. However, when I register this schema and then try to generate an xml document (either from the registered xsd either from a filesystem xsd) with person as starting node it fails with the mentioned error. However, when I use city as starting node it is generated successfully.
