XML validation against XMLSchema

Hi!
Could anybody give me a clue, where can I find a good tutorial about the topic?
Is there any source code that you tried and worked?
I have some problems with few examples and maybe your working code will shoot the bulls eye for me. :)
Thanks in advance,

Hi!
This Exception is walking with me through all the time I play with XML Schema.
java.util.MissingResourceException: Can't find bundle for base name org.apache.xerces.impl.msg.XMLMessages, locale pl_PL
When I change system locale to EN, then Exception still occurs but with the "en_US" phrase.
Help, please!

XML validation against XSD

Hi,
Does Oracle 8i (Release 3) support XML validations against XSD? I know Oracle 9i (Release 2) supports XML validations against XSD.
Also, Does Oracle support XML validations against XDR?
Any info is appreciated.
Thanks
Pavan

Validate with DOMParser or the SAXParser.

Question about XML validation against schema

My question is probably a basic one about XML. I tried PurchaseOrder example from the book "J2EE Web Services" by Richard Monson-Haefel. A simplified version as followings -
Address.xsd -
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://xml.netbeans.org/schema/Address"
xmlns:addr="http://xml.netbeans.org/schema/Address"
elementFormDefault="qualified">
<element name="address" type="addr:USAddress" />
<complexType name="USAddress">
<sequence>
<element name="name" type="string" />
<element name="street" type="string" />
<element name="city" type="string" />
<element name="state" type="string" />
<element name="zip" type="string" />
</sequence>
</complexType>
</schema>
PurchaseOrder.xsd -
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://xml.netbeans.org/schema/PurchaseOrder"
xmlns:po="http://xml.netbeans.org/schema/PurchaseOrder"
xmlns:ad="http://xml.netbeans.org/schema/Address"
elementFormDefault="qualified">
<import namespace="http://xml.netbeans.org/schema/Address" schemaLocation="Address.xsd" />
<element name="purchaseOrder" type="po:PurchaseOrder" />
<complexType name="PurchaseOrder">
<sequence>
<element name="accountName" type="string" />
<element name="accountNumber" type="unsignedShort" />
<element name="shipAddress" type="ad:USAddress" />
<element name="total" type="float" />
</sequence>
<attribute name="orderDate" type="date" />
</complexType>
</schema>
Then PurchaseOrder.xml is -
<purchaseOrder orderDate="2007-12-12"
xmlns='http://xml.netbeans.org/schema/PurchaseOrder'
xmlns:addr="http://xml.netbeans.org/schema/Address"
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xsi:schemaLocation='http://xml.netbeans.org/schema/PurchaseOrder ../xsd/PurchaseOrder.xsd'>
<accountName>Starwood</accountName>
<accountNumber>220</accountNumber>
<shipAddress>
<name>Data Center</name>
<street>1501 Washington St.</street>
<city>Braintree</city>
<state>MA</state>
<zip>02148</zip>
</shipAddress>
<total>250</total>
</purchaseOrder>
Then I did a XML validation but have this error -
cvc-complex-type.2.4.a: Invalid content was found starting with element 'name'. One of '{"http://xml.netbeans.org/schema/Address":name}' is expected. [19]
It complains <name> tag in <shipAddrss> needs namespace of "http://xml.netbeans.org/schema/Address". Why?
Is it possible to change XML so it does not need name space for elements inside <shipAddress>?
Thanks

Obviously, the w3c.org domain that you specified as ressource location is very slow - and, as the FAQ shows, this delay is intentional!
The W3C servers are slow to return DTDs. Is the delay intentional?
Yes. Due to various software systems downloading DTDs from our site millions of times a day (despite the caching directives of our servers), we have started to serve DTDs and schema (DTD, XSD, ENT, MOD, etc.) from our site with an artificial delay. Our goals in doing so are to bring more attention to our ongoing issues with excessive DTD traffic, and to protect the stability and response time of the rest of our site.

QUESTION: XML validation against a schema - for beginners

Hi folks,
i am new to XML validation.
i would like to find out how to validate an XML file using a schema given to me by a third part company.
the business process requires that our company sends a weekly file which complies with their schema.
in real-life, i am expecting some details of our file to fail against their schema.
thus i would like to find a way validating the file localy before sending it to this third part.
this validation would ideally allow me to highlight and identify which records are failing the validation, and enable me to strip those and send only those that are successfully checked.
on the example below, i would expect to have the record for John Smith to be successful (country has an integer); while Queen Victoria would fail as it uses UK instead of an integer to identify the country.
thus i would need to find a way validating this XML file, move the record of Queen Victoria to another file to be fixed and to allow, the record for John Smith to be sent out.
if you guys could post some links to where i can find further information on this type of processing, i would be most grateful.
Many thanks,
Nicolas

XML validation against schema in XSD format

I have a requirement for validation of XML file against XML schema(XSD format). Using IXML liabrary I know how to validate XML file against schema in DTD format. But i am not getting how to do it against XSD. Is it possible using IXML liabrary? Also i wanted to know how to attach one XML or CSV file into another XML file using SAP ABAP.
Please provide solution!!

Using XSL on XML validated against XSD

Transforming XSD validated XMLType Data
Re: example XSL in Chapter 6 that transforms XML with associated XSD schema definition (Oracle 9i XML Database Developer's Guide)
I noted that this XSL uses only the "general" node identification functions (e.g., name() ) to access nodes in the <xsl:value-of select..>. I have also noted that standard XSL templates from other sections of the documentation, for example in Chapter 3 and in Appendix D, do not work with an XML which is validated against an XSD schema.
Can anyone give me an example <xsl:value-of select..> that addresses a specific node in the "purchase order" example, like the shipTo, name, street -- or any other specific node. This is critical since there is always bound to be node-specific processing in any transformation, and this is not demonstrated by any example of XML which has been validated against an XSD.
I have tried this endlessly on my own examples of XML w/XSD validation. Even if the value-of select="name(.)" tells you that the name of the node is "FooBar", you cannot use FooBar as a select test to do FooBar specific processing.
Help?????

Not quite understand your question. Can you send me the example doc?

XML validation against DTD.. Is it possible?

Hello all,
Sorry for what may be a trivial post, but I'll keep it short..
According to the docs:
"The Validate XML command will validate the XML against the schema defined in the XML file. This command on the context menu is disabled whenever an XML file does not have an XML namespace defined."
I'm used to the XML editor retrieving a DTD from somewhere and validating it against that.. is it possible to do this in JDev?

Unfortunately it's not. We only have support for validating against XML Schemas.

XML validation against DTD

Hi,
I have an application that receives XML from an external source. The XML received does not have the XML version and the doc type declaration lines. I want to validate the XML against a DTD.
One dirty way of doing this is to open the XML received and prepend the XML versions and doctype lines to it. And then parse the XML. But is it the right way to do it?
What I would like to know is that does the XML parser provide any API which can tell it to validate an XML document against a certain DTD.

Yes, there is an API to do this. You have to do something like this:
DocumentBuilderFactory dbf =DocumentBuilderFactory.newInstance();
dbf.setValidating(true);
DocumentBuilder db = dbf.newDocumentBuilder();
XMLErrors eh = new XMLErrors(frame);
db.setErrorHandler(eh);
Document doc = db.parse(f);
(where f is the XML file)
In this example, the class XMLErrors is used as the ErrorHandler. XMLErrors extends the DefaultHandler class and provides the user with information about the various error levels. A call to the over-ridden "error" method notifies the user (using a Dialog box) that the document doesn't meet the DTD.
Hope this helps.

XML validation against registered XSD

I have registered XSD into oracle database, while validating xml against this xsd I got stuck with non-mandatory tags.
Below is the tag-XSD structure:
Status field as String:
<xs:element name="Status" nillable="false"> <xs:annotation> <xs:documentation>Values are 'N' or 'E'</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:maxLength value="1"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
idnumber tag field as Integer:
<xs:element name="idnumber" type="xs:int" nillable="false">
<xs:annotation>
<xs:documentation>id value </xs:documentation>
</xs:annotation>
</xs:element>
As status tag is of string type and I have mentioned it as nillable = "False", but even though when I am passing this tag as <status/>, then also its validating xml.... but as i mentioned nillable property as false then it should not validate it ..... please correct me if i m wrong..
In case of idnumber tag it is of int type. In this case <idnumber/> will not work in either case even it is nillable = true or false. Means we cannt pass null values in integer field..... right?
Please suggest me how to make tag of string datatype as not nillable.
Is there any significance of using nillable = "false" in int datatype tag. Means if we want to make it as optional then need to mention it as minoccurs = 0..... is it correct?
Requirement is simple:
Just want to make some tag as optional and some as mandatory, tag can be of integer or string type.
Thanks in advance.....

The nillable attribute doesn't work that way. It's easy to look that up in any tutorial.
nillable = "true" means you allow the element to have a NULL content (different from empty string) by specifying an explicit null attribute :
<Status xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>nillable = "false" is the default behaviour.
Please suggest me how to make tag of string datatype as not nillable.

Requirement is simple:
Just want to make some tag as optional and some as mandatory, tag can be of integer or string type. You have to be careful about the vocabulary.
In my mind, an "optional" element means you can omit it entirely in the instance document (minOccurs="0"), whereas an empty element means the start tag and end tag are there but with no content.
There are multiple ways to allow for empty or non-empty elements.
e.g. for a non-empty string :
<xs:minLength value="1"/>or, as in your example, if the content is actually constrained to a list of values, use enumerations.
xs:int datatype doesn't allow empty values (unless you use xsi:nil).
A possible solution is to build a new type by unioning (xs:union) an xs:int and an empty string type.

XML validation against schema (NOT DTD)

Hi,
I am fairly new at parsing XML documents, but I am trying to parse
an XML document using the Xerces SAXParser.
I can parse my xml document, no problems there, but I want to validate
it against an xml schema file, without specifying the file in the xml document.
How can I do this? If I set validating to true, it gives me errors about a DTD,
but I don't have a DTD, I want to use a schema file.
Can anybody help me, or give me a code example?
THanks,
Sven

SAXParser parser = new SAXParser();
             parser.setFeature("http://xml.org/sax/features/validation",
                      true);
             parser.setFeature("http://apache.org/xml/features/validation/schema",
                      true);
             parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking",
                      true);

XML validation against XSD Schema in ABAP

Hi colleagues,
I'm looking for a way to validate a XML against a XSD schema in ABAP, without using java or command line or something like that. Is there any way to do this only with ABAP?
Thanks in advance.
Regards,
Guenter

Hi everyone,
I'm currently facing the same problem. I need to validate a xml file with an existing xsd schema for some export/import functionality. I just found an ABAP program doing this with a Java fallback. But isn't there a way doing this wihtout using Java but only ABAP? There certainly is, anyone an idea?
Thank you and regards
