XMLValidatingRe ader desperate...

[sorinuc]

Hi all,

I'm quite desperate after so much time of frustration trying to
validate an xml doc with a schema using XmlValidatingRe ader. I know I
miss something but I cannot solve this for the life of me:

My xsd is:

<xs:schema targetNamespace ="http://myUrl.com"
elementFormDefa ult="qualified"
attributeFormDe fault="qualifie d" xmlns:a="http://myUrl.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
....
....
<xs:element name="mainNode" >...

The xml file is:

<?xml version="1.0" encoding="UTF-8"?>
<mainNode xmlns:xsd="http ://www.w3.org/2001/XMLSchema"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xmlns:a="http://myUrl.com">
.....
other elements here...
</mainNode>

This is my code using XmlValidatingRe ader:

Dim _reader As New XmlValidatingRe ader(xmlFragmen t,
XmlNodeType.Ele ment, Nothing)
Dim _xsc As New XmlSchemaCollec tion

__isValid = True

_xsc.Add("http://myUrl.com", New XmlTextReader(s chema))

' I have tried this as well:
'_xsc.Add(Nothi ng, New XmlTextReader(s chema))

_reader.Schemas .Add(_xsc)
_reader.Validat ionType = ValidationType. Schema

AddHandler _reader.Validat ionEventHandler , AddressOf
ValidationCallB ack

While _reader.Read()
End While
....

And the ValidationCallB ack sub just changes the value of __isValid to
false.

Anytime I call the validation routine it returns false and the message
error is:
The 'mainNode' element is not declared. An error at , (..)

If I changed the elementFormDefa ul and attributeFormDe fault to
"unqualifie d" everything is fine.

I would prefer buying you beer rather than banging my head against the
walls.

You don't declare default namespace in your xml document, so the validator
doesn't find the mainNode element in your schema. Change your xml file to
read:

<mainNode xmlns="http://myUrl.com">
...
</mainNode>

It doesn't look like you were using the other two namespaces, so I removed
them. If you need them, feel free to put them back. Also, you haven't
defined the default namespace in your schema, which might cause some
problems. Since you haven't posted the entire schema, I can't tell. And
finally, you might want to change the attributeFormDe fault to "unqualifie d".
