going to fetch a value from xml response when going to parse but i am fail to get value

Question

Below code is the response from the server:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><SendCardDetailsResponse xmlns="http://tempuri.org/"><SendCardDetailsResult><ROOT xmlns=""><DocumentElement><res-auth><auth-data count='1' ><**attribute name='OTP1'** length='6' type='N' label='OTP' prompt='Please enter OTP as send to your mobile.'/></auth-data></res-auth></DocumentElement></ROOT></SendCardDetailsResult></SendCardDetailsResponse></soap:Body></soap:Envelope>

I have to fetch attribute name which is 'OTP1' how can I get value of attribute name any help will be appreciable

Answer 1

I would use smth like this:

-(NSString*) getAttribute{
    NSString *attribute = @"";
    NSString *xmlString = @"";//put the XML in this NSString
    int endOfSrc = [xmlString rangeOfString:@"\"><attribute name='"].location+[xmlString rangeOfString:@"\"><attribute name='"].length;
    int borderPos = [xmlString rangeOfString:@"' length='"].location;
    if(borderPos != NSNotFound){
        NSRange range;
        range.location = endOfSrc;
        range.length = borderPos - endOfSrc;
        attribute = [xmlString substringWithRange:range];
        return attribute;
    }
    return @" ";
}

Nothing hard here, if some questions about the code appear, just see the documentation for the functions i've used here. maybe there are more efficient ways, dunno. It works like a charm for me.
