Question

I have an XML file with IDs, names and URLs stored in it

I need to read the file and check the value of the ID. If it is equal to soe parameter, I will read the name and URL and stop checking. Else I advance to the next element and do the same check.

I have the following code for iPhone. It is similar to what I need to do, but I need to do it on Android:

NSString *url = @"my http url to get xml file";    
NSURL *xmlURL = [NSURL URLWithString:url];
XMLParser *parser = [[XMLParser alloc] initXMLParser];

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
      namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName     
{
    if([elementName isEqualToString:@"person"])
    {
        Pickers.person= person; 
        Pickers.fullName   = fullName;
        Pickers.ID = ID;
        Pickers.URl = URl;
        return;
    }

    //There is nothing to do if we encounter the Books element here.
    // and release the object.

    NSString *P_ID ;
    NSString *P_URl;

    if([elementName isEqualToString:@"ID"]) 
    {
        P_ID = currentElementValue;
        NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"\n"];

        P_ID = [[P_ID componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];

        P_ID =  [P_ID stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceCharacterSet]];

        [ID addObject:P_ID];
    }    
    else if([elementName isEqualToString:@"Name"]) 
    {

        [fullName addObject:currentElementValue];
    }
    else  if([elementName isEqualToString:@"Symbol"]) 
    { 
        [person addObject:currentElementValue];
    }
}

else if([elementName isEqualToString:@"URl"]) 
{
    P_URl = currentElementValue;
    NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"\n"];

    P_URl = [[P_URl componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];

    P_URl =  [P_URl stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceCharacterSet]];

    [URl addObject:P_URl];
}


}

Also I want to know which is better to use in my case: SAX parser, DOM parser or XMLPullParser?

Answer 1

after a long research and trial and error i fond the most efficient and easiest (less code, less bugs) is to use Simple framework; it is amazing how easy and fun to use!
