How to dynamically load schema from a file and then assign to xmldocument and validat

[kamii47]

I am creating in memory xmldocument.Pre viously I were validating my file against a dtd file and then by the help of GetElementByID read my needed node.
i.e.

XmlDocumentType doctype = null; 
doctype = statementsDocument.CreateDocumentType("queries", null,statementsPath +"\\Validation.dtd", null); 
statementsDocument.AppendChild(doctype); 
nodeElem = statementsDocument.CreateElement("queries"); 
statementsDocument.AppendChild(nodeElem); 
.... 

Now I have created validate.xsd.I don't know how to validate through xsd file
Sometime Later I want's validate from this validate.xsd then read my element by Get element ByID()



MY validate.dtd were

<?xml version="1.0" encoding="UTF-8"?> 
<!--DTD generated by XMLSpy v2006 sp2 U (http://www.altova.com)--> 
<!ELEMENT queries (query+)> 
<!ELEMENT query (statement)> 
<!ATTLIST query 
type CDATA #REQUIRED 
id ID #REQUIRED 
> 
<!ELEMENT statement (#PCDATA)> 

and now my validate.xsd is

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> 
<xs:import namespace="http://www.w3.org/XML/1998/namespace"/> 
<xs:element name="queries"> 
<xs:complexType> 
<xs:sequence> 
<xs:element ref="query" maxOccurs="unbounded"/> 
</xs:sequence> 
</xs:complexType> 
</xs:element> 
<xs:element name="query"> 
<xs:complexType> 
<xs:sequence> 
<xs:element ref="statement"/> 
</xs:sequence> 
<xs:attribute name="type" type="xs:string" use="required"/> 
<xs:attribute name="id" type="xs:ID" use="required"/> 
</xs:complexType> 
</xs:element> 
<xs:element name="statement"> 
<xs:complexType mixed="true"> 
<xs:choice minOccurs="0" maxOccurs="unbounded"/> 
</xs:complexType> 
</xs:element> 
</xs:schema>
