trouble validating against xsd

[Jon Poploskie]

Hello,

I have an xsd file that I'm trying to use to validate some xml against. I'm
hoping this is a simple problem, but I just don't see it. I get the error
"The 'role' element is not declared." when trying to validate this xml:

<users>
<user id="jon" pwd="pass">
<roles><role>Ad min</role></roles>
</user>
</users>

Against this schema:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema elementFormDefa ult="unqualifie d" xmlns=""
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="users">
<xs:complexType >
<xs:sequence>
<xs:element name="user" minOccurs="0" maxOccurs="unbo unded">
<xs:complexType >
<xs:sequence>
<xs:element name="roles" minOccurs="0" maxOccurs="1">
<xs:complexType >
<xs:sequence minOccurs="0" maxOccurs="unbo unded">
<xs:element name="role" type="xs:string ">
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="id" type="xs:string " />
<xs:attribute name="pwd" type="xs:string " />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Any thoughts?

Thank you very much!
Jon

The schema seems to be ok and xml looks valid against it. In caannot
repreoduce the problim neither in XML Spy nor in .NET. Make sure you
ahve posted real XML and schema and show us your code.

Hi Jon,

Can you show the code you used to valid the XML file? This may help us
better understand the problem. Thanks.

Oleg,

That was the actual XML fragment and the real schema. Here is the code I'm
using to validate it:

private void ValidateSchema( XmlNode node)
{
Stream xsdFile;

XmlValidatingRe ader val = new XmlValidatingRe ader(new XmlTextReader(
new StringReader(no de.OuterXml)));
val.ValidationT ype = ValidationType. Schema;

xsdFile = Resource.Resour ceManager.GetSt ream("users.xsd ");
val.Schemas.Add (XmlSchema.Read (new XmlTextReader(x sdFile), null));
val.ValidationE ventHandler +=new
ValidationEvent Handler(Validat ionCallBack);

// Read the document
while(val.Read( ) && _isValidDoc) {}
if(!_isValidDoc )
throw new ApplicationExce ption("Not a valid user xml file.");
}

private void ValidationCallB ack( object sender, ValidationEvent Args args )
{
_isValidDoc = false;
}

The code is based on the validation code in the MS UIProcess Application
Block. The only other thing I can think of it that the schema has a
different encoding than the document, would that make a difference (utf-8 vs
uts-16)?

Thanks!
Jon

Well, the only suspicious place left is
Resource.Resour ceManager.GetSt ream("users.xsd ") - are you sure it returns the
schema you have posted?
The following code works ok to me, no validation errors:

public class Test {
static bool _isValidDoc = true;

static void Main(string[] args) {
string xml =
@"<users>
<user id=""jon"" pwd=""pass"">
<roles><role>Ad min</role></roles>
</user>
</users>";
string xsd =
@"<?xml version=""1.0"" encoding=""utf-8"" ?>
<xs:schema elementFormDefa ult=""unqualifi ed"" xmlns=""""
xmlns:xs=""http ://www.w3.org/2001/XMLSchema"">
<xs:element name=""users"">
<xs:complexType >
<xs:sequence>
<xs:element name=""user"" minOccurs=""0"" maxOccurs=""unb ounded"">
<xs:complexType >
<xs:sequence>
<xs:element name=""roles"" minOccurs=""0"" maxOccurs=""1"" >
<xs:complexType >
<xs:sequence minOccurs=""0"" maxOccurs=""unb ounded"">
<xs:element name=""role"" type=""xs:strin g"">
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name=""id"" type=""xs:strin g"" />
<xs:attribute name=""pwd"" type=""xs:strin g"" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>";
XmlValidatingRe ader val = new XmlValidatingRe ader(new XmlTextReader(
new StringReader(xm l)));
val.ValidationT ype = ValidationType. Schema;

val.Schemas.Add (XmlSchema.Read (new XmlTextReader(n ew
StringReader(xs d)), null));
val.ValidationE ventHandler +=new
ValidationEvent Handler(Test.Va lidationCallBac k);

// Read the document
while(val.Read( ) && _isValidDoc) {}
if(!_isValidDoc )
throw new ApplicationExce ption("Not a valid user xml file.");

}
public static void ValidationCallB ack( object sender, ValidationEvent Args
args )
{
if (args.Severity == XmlSeverityType .Error)
_isValidDoc = false;
}
}
