Error: Content is not allowed in prolog in Groovy script - groovy

Question

I tried to run following xsd validation in SoapUI using Groovy
import javax.xml.XMLConstants
import javax.xml.transform.stream.StreamSource
import javax.xml.validation.*
// setup validator
Validator validator;
def url = "file:///D:/SoapUI/XSDFile.xsd"
log.info url
URI uri = new URI(url);
InputStream inp = uri.toURL().openStream();
try
{
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
StreamSource entitySs = new StreamSource(inp);
Schema schema = factory.newSchema(entitySs);
assert(schema != null);
validator = schema.newValidator();
}
finally
{
inp.close();
inp = null;
}
def response = context.expand( "file:///D:/SoapUI/response.xml" )
log.info response
validator.validate(new StreamSource(new StringReader(response)))
But I am getting below error in the groovy step in the SoapUI test Case
:ERROR:org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.
org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.

As per solution given on the web I removed unwanted characters though I cannot see as such by converting file from UTF8 file to ANSI
But still giving the same error
Is this caused some other issue?
