Question

I am getting a response from a web service call in XML format. I want to search for the status string in the XML response and proceed further depending on its value. How can I do this? The response is below:

<META NAME="ColdFusionMXEdition" CONTENT="ColdFusion DevNet Edition - Not for Production Use."><?xml version="1.0" encoding="UTF-8"?>
<ParticipantService>
    <Response>
        <student_id>10082</student_id>
    </Response>
    <RequestStatus>
        <Code>1</Code>
        <Status>SUCCESS</Status>
        <Message>Valid Credentials.</Message>
    </RequestStatus>
</ParticipantService>

You can use NSXmlParser. If you are checking only for status you can do some string manipulation as follows,

NSString *mystring = @"<Response><status>SUCCESS</status> </Response>";
NSString *neededString = nil;
NSScanner *scanner =[NSScanner scannerWithString:mystring];
[scanner scanUpToString:@"<status>" intoString:NULL];
[scanner scanString:@"<status>" intoString:NULL];
[scanner scanUpToString:@"</status>" intoString:&neededString];
NSLog(@"%@",neededString);
if ([neededString isEqualToString:@"SUCCESS"]){  //do what you like. }
