I am calling one web service and getting response in XML and while iterating through that XML i got below exception
System.XmlException: ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog.
Code:
HttpRequest req = new HttpRequest();
String url='abaccc';
req.setEndpoint(url);
req.setMethod('GET');
// Send the request, and return a response
HttpResponse res = h.send(req);
XmlStreamReader reader = res.getXmlStreamReader();
// Read through the XML
while(reader.hasNext()) {
System.debug('Event Type:' + reader.getEventType());
if (reader.getEventType() == XmlTag.START_ELEMENT) {
System.debug('Local name :'+reader.getLocalName());
}
reader.next();// Getting exception at this line.
}Can anybody help me?
Thanks

Hey Yash,did you get solution for this????
Occasionally the XML stream that is returned has a "hidden" character before the first "<". In this case you will receive the ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog error message. In order to move past this hidden character and get to the xml you are trying to parse use the following:
//Obviously do your setup before this point
//Send the request and return a response
HttpResponse res = h.send(req);
result = res.getBody(); //Get the result
result = result.substring(1); //Move past the first character but keep the remainder of the string (which is the XML you want)
This worked for me.
Just encountered the same error, in my case, I used next() method initially in traversing the StreamReader else to move to the next node, before doing the loop --
XmlStreamReaderVariable.next();
