Get valid elements using XmlSchema - .NET

[merdaf]

Hallo all,

I am looking for a funcion in the .Net framework that returns a list of
all the valid elements, for a specific element, accrording to the xml
schema restrictions.

I will try to be more accurate using this example:
if this is the xml
<a>
<b>
</b>
</a>

and this is the xml schema:
<xs:element name="a">
<xs:complexType>
<xs:sequence>
<xs:element name="b" type="xs:string"/>
<xs:element name="c" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>

I am looking for a function that returns the element 'c' as the only
element valid for element 'a' (and this is true because element 'b' is
already decleared in the xml)

I have used XmlSchemaValidator.GetExpectedParticles() but it doesn't
help - it returns all the possible values regardless to the xml data.
in this case it returns a list with both 'b' and 'c'.

I really appreciate any help in this matter,
Thanks in advance,
Izik Lisbon

XmlSchemaValidator.GetExpectedParticles() is the right method to use.
XmlSchemaValidator is a push model validation engine and
GetExpectedParticles will return expected elements given the current state
of the validator.
Consider the following sequence of calls,
ValidateElement(a)
GetExpectedParticles() -Should return b since b is the next expected
element as a's first child
ValidateElement(b)
ValidateEndElement() -closing b's context
GetExpectedParticles() -should return c since c is the next expected
sibling

Thanks,
Priya
