Sandy (et al), I've been out of touch with XML for a couple years (remember back when there were no schemas and namespaces?).
Basically, you're saying that the schema against which the XML instance is validated and the namespace in which that instance exists are independent unless you specify a targetNamespace in the schema, in which case the instance must use that namespace. Right? BTW: Is it just me or does anyone else find it odd that XML schema is used to validate existing XML "instances" (a.k.a. documents) and everywhere else on the planet schema is used to create instances? (although I suppose an argument could be made that an SQL UPDATE statement is validated against the database schema before it is executed.) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 04, 2001 2:00 PM To: [EMAIL PROTECTED] Subject: Re: More validating schema problems... Hi Pete, In your schema file, you specified a targetNamespace, so in your instance document, you should tell the parser that your element is from that namespace. Change your instance document to the following should solve the problem: <?xml version="1.0"?> <test xmlns="http://localhost"; xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"; xsi:schemaLocation="http://localhost test.xsd"> </test> Cheers, Sandy Gao Software Developer, IBM Canada (1-416) 448-3255 [EMAIL PROTECTED] [EMAIL PROTECTED] .com To: [EMAIL PROTECTED] cc: 04/04/2001 Subject: More validating schema problems... 02:26 PM Please respond to xerces-j-user Hello all, I was looking through the recent schema validating posts, but didn't see a complete resolution to the issues, or at least a resolution to the issue that I am running into. This issue is with an error generated by the parser when validating a schema: "Element type "test" must be declared." I thought what I thought were valid xsd/xml documents and am calling the parser correctly. I then took almost everything out of the files, and was still getting the error.. Obviously I'm doing something wrong... I was hopeing that someone would spot my mistakes. Also, I've been scouring the schema tutorial at xml.com, which seems to be the best schema reference I could find. I also downloaded a schema tutorial, and from what I can tell, I'm doing what they say... I think I've got a reasonable handle on schemas, except for this little problem... I'm guessing the problem is in the header somewhere, as the parser does read from the schema file. I can't find a good document on all the information that should/needs-to be put in the header, anyone know of one? I call the parser with: jre -classpath %xerces_CLASSPATH% sax.SAXCount -s -v test.xml My xml and xsd files look like: <?xml version="1.0"?> <test xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"; xsi:schemaLocation="http://localhost test.xsd"> </test> ------------------------------- <?xml version="1.0"?> <xsd:schema xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"; targetNamespace="http://localhost"; xmlns="http://localhost"; elementFormDefault="qualified" attributeFormDefault="unqualified"> <xsd:element name="test" /> </xsd:schema> Thanks for any help! -Pete --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
