I am using Soap UI 5.7.0, i’m new in scripting. below script is failing with error ‘ERROR:An error occurred [Failed to dispatch using script; org.apache.xmlbeans.XmlException: error: Content is not allowed in prolog.], see error log for details’ What to do to resolve it.

import groovy.xml.*

import groovy.sql.Sql

import groovy.lang.Binding;

import groovy.lang.Script;

def requestBody="";

try {

while ((line = mockRequest.getrequestContent().getReader().readLine()) != null)

{

requestBody = requestBody+line;

}

} catch (Exception e) {

log.info(e)

}

def groovyUtils = new com.eviware.soapui.support.GroovyUtils(mockRequest.requestContext);

def holder = groovyUtils.getXmlHolder(requestBody);

def CCNumReq = holder.getNodeValue("//cardNumber");

requestContext.ccnum = CCNumReq

Expecting return value as one of the tag value from request xml.
