	xmlns:xsd="http://www.w3.org/1999/XMLSchema"
	xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
	xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" 
	SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
	<SOAP-ENV:Body>
		<mns:ProcessSRL xmlns:mns="http://www.SoapClient.com/xml/SQLDataSoap.xsd">
			<SRLFile xsi:type="xsd:string">/xml/whois.sri</SRLFile>

    If Not Reader.Fault Is Nothing Then
        MsgBox Reader.faultstring.Text, vbExclamation
    Else
