Validation Problem - .NET Framework

Harry_Crow

I have a schema file PDDSch.xsd which validates the PDD.xml file. the
rootnodes are as shown below

PDD.xml
<PDD xmlns="http://tempuri.org/PDDSch.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-Instance" >

PDDSch.xsd
<xs:schema id="PDD"
targetNamespace="http://tempuri.org/PDDSch.xsd"
xmlns="http://tempuri.org/PDDSch.xsd"
xmlns:mstns="http://tempuri.org/PDDSch.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
attributeFormDefault="qualified"
elementFormDefault="qualified">

now with the above mentioned namespaces and other attributes the validation
works properly. But I'm not able to read the child nodes through
XPathNavigator and XPathNodeIterator.

If the above rootnodes changed as shown below.

PDD.xml
<PDD xmlns:xsi="http://www.w3.org/2001/XMLSchema-Instance"
xsi:noNamespaceSchemaLocation="PDDSch.xsd">

PDDSch.xsd
<xs:schema id="PDD"
xmlns:mstns="http://tempuri.org/PDDSch.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"
attributeFormDefault="qualified"
elementFormDefault="qualified">

With the above rootnode attributes theXPathNavigator and XPathNodeIterator
will read the child nodes. but the validation is not correct.

Could someone tell me What is the mistake I'm making here.

Thanks and regards,
Harry

Could you share the code and the data that you are using. You should be able
to walk the child nodes in both cases.

This is the Code:

I have not assigned any namespaceManager or ParserContext for the rootNode

XmlDocument doc = new XmlDocument();
doc.Load("PDD.xml");
XmlNode rootNode = doc.DocumentElement;
XPathNavigator nav = rootNode.CreateNavigator();
XPathExpression exp = nav.Compile("//PD/*"); //PD is the child node of PDD
XPathNodeIterator it = (XPathNodeIterator) nav.Evaluate(exp);

while(iterator.MoveNext())
{

}

not entering the while loop itself.

Harry

Associate a context to your XPathExpression and pass a NamespaceManager
which has the namespace http://tempuri.org/PDDSch.xsd mapped to a prefix
which you then should use in your query. The method you should use:

exp.SetContext ( NamespaceManager);

nope not entering the while loop yet.
could you please tell me what the follwing error means

The 'http://www.w3.org/2001/XMLSchema-Instance:noNamespaceSchemaLocation'
attribute is not declared.

I have specified the rootnode of PDD.xml as below.
<PDD xmlns:xsi="http://www.w3.org/2001/XMLSchema-Instance"
xsi:noNamespaceSchemaLocation="PDDSch.xsd">

Is it the problem that it is not able to link to PDDSch.xsd file.

what it means by "attribute not declared"

Thank you,

The correct namespace declaration is:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

note the small 'i' in the instance.

Well it was a stupid error, I was working with visual studio and could not
make out the error, When I checked it in XML spy which said "xml file not
well formed".
It was a great help from your side.
Thanks a lot Abbas
