I want to parser both the parent and child tag contents. But The Child tag contents are are found null. I looked various posts and tutorials but undone.Can any one help me please
Add an Log on the didStartElement method and see if all the tags are logged.It will be listed properly and you have to extract it in the rightway
NSLog(@"\n%@", elementname);
See how the parser works first adding this tag.It is not in the parent child way the parser parse the data.It is just First come first serve way the values approch aand you have to write the logic supporting that
For more information on parsing Read this document by apple
