I'm trying to validate an XML file with XSD, but I get a " Could not find schema information for the element 'xxx' " for each element and attribute.
My C# code is:
public ReadeXmlFile(string FilePath)
{
var settings = new XmlReaderSettings
{
IgnoreComments = true,
ValidationType = ValidationType.Schema,
CheckCharacters=true,
ValidationFlags= XmlSchemaValidationFlags.ReportValidationWarnings
};
settings.ValidationEventHandler += settings_ValidationEventHandler;
var xsdReader = new XmlTextReader("KeyEmFileSchema.xsd");
settings.Schemas.Add(null, xsdReader);
using (var reader = XmlTextReader.Create(FilePath, settings))
{
while (reader.Read()){}
}
}
void settings_ValidationEventHandler(object sender, ValidationEventArgs e)
{
Debug.WriteLine(e.Severity + " - " + e.Message);
}
My XML file:
<?xml version="1.0" encoding="utf-16"?>
<keyem description="test"

according to your schema you have a wrong node inside of your xml :
<groupp text="rad 1">
Just group or key element could be inserted at that level.
Concerning your specific problem try to use the next root node inside your schema file :
<xs:schema id="FileSchema"
elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
...
</xs:schema>
If you defined schema in the KeyEmFileSchema.xsd
file you can use schemaLocation
instead of noNamespaceSchemaLocation
:
<keyem description="test"
xmlns="http://tempuri.org/KeyEmFileSchema.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:schemaLocation="http://tempuri.org/KeyEmFileSchema.xsd KeyEmFileSchema.xsd"
>
which defines file name (it can be with the path if required) where the definition http://tempuri.org/KeyEmFileSchema.xsd
can be found and used. Then you can use
XmlReaderSettings settings = new XmlReaderSettings ();
settings.ValidationType = ValidationType.Schema;
settings.IgnoreWhitespace = true;
settings.IgnoreComments = true;
settings.ValidationFlags = XmlSchemaValidationFlags.ProcessSchemaLocation;
XmlReader reader = XmlReader.Create (xmlFilePath, settings);
If you want you can additionally use ValidationEventHandler
. Without the handler you will receive exception with the information about validation errors.
UPDATED : By the way after including of xmlns="http://tempuri.org/KeyEmFileSchema.xsd"
and xsi:schemaLocation="http://tempuri.org/KeyEmFileSchema.xsd KeyEmFileSchema.xsd"
in the root element of your xml file you will be seen already in Visual Studio Text Editor the errors in your XML file:
description
in keyem
element. layout
element which are also undeclared. groupp
element instead of group
. UPDATED 2 : The requirement number 3: to replace groupp
to group
is clear. Because nobody commented my answer I suppose that somebody ask "what is wrong with attributes of the XML file?". OK I have to comment this more.
The problem in your XSD file is that you declare attributes as NOT a part of some simple types, attribute group or attributes of some element . You just declare some "independent" attributes and then use there per "ref" reference. It is in general possible, but this way require usage of qualified attributes . So if you make no changes in your schema the fixed version of your XML file will be following
<?xml version="1.0" encoding="utf-16"?>

</group>
</layout>
</keyem>
A small remark : <empty>
element is wrong defined in your schema, so to follow the schema we have to use it like <empty><empty/></empty>
.
Another version of possible changes (which you will probably prefer) is to place all attributes in the definition of elements or attribute group . Usage of simple types in your case seems me not needed. So the fixed version of the schema can be following:
<?xml version="1.0" encoding="utf-16"?>

If we save the new schema in the file KeyEmFileSchema1.xsd
then KeyEmFileSchema.xml
file can be almost the same as you have before:
