Here: http://www.w3.org/TR/sprot11/ I read that wsdl can be download from adress http://www.w3.org/TR/sprot11/sparql-protocol-query-11.wsdl but these wsdl import xsd which doesnt exits: http://www.w3.org/TR/rdf-sparql-XMLres/result2.xsd . I wrote w3c 3 days ago but still no aswer. is there some other server where I can download all xsd about sparql which I need ?

I went ahead and downloaded the wsdl that you mention in your question, but cannot find a reference to an xsd other than this one:

<xs:schema targetNamespace="http://www.w3.org/2005/08/sparql-protocol-query/#">
    <xs:import namespace="http://www.w3.org/2005/09/sparql-protocol-types/#"
             schemaLocation="http://www.w3.org/2001/sw/DataAccess/proto-wd/sparql- 
             protocol-types.xsd" />
</xs:schema>

The xsd in the excerpt above is available at the URL given in the schemaLocation attribute.
